Cryptocurrency wallets are a type of light software needed to interact with a decentralized network, like Bitcoin, Ethereum, or Obyte. As the name suggests, they mostly work to store funds and make payments, but using different kinds of decentralized apps (Dapps) is also on the table in the crypto world. Every distributed ledger often has its own wallet, but that doesn’t mean they can’t cooperate. That’s the case with MetaMask and Obyte. MetaMask is, likely, the most popular crypto wallet for Ethereum-compatible networks and tokens. It was released in 2016 by ConsenSys, as free and open-source software. It’s available as a simple web browser extension or mobile app, and it’s easy enough to set up and handle. You’ll recognize it everywhere for its characteristic low-poly fox logo that may follow the movements on your touchscreen or your mouse. What can you do with MetaMask? After the installation on your preferred device, the first thing you’ll need to do is make a backup of your seed. In other words, write down and safely keep the string of random words that’ll be the only help to recover your funds if you happen to uninstall the app or lose the device. This is an important step when using any crypto wallet, not only MetaMask. Setting up a password is also a good idea. Then, you can start storing and trading funds through the app, just by selecting a crypto network and using the crypto addresses provided by your recipients, or sharing your own to receive. MetaMask, of course, manages Ether (ETH) and ERC-20 tokens inside Ethereum (such as the most popular stablecoins). However, you can also select tokens from other compatible ledgers, including Polygon, BNB Chain, Avalanche, Kava, and Gnosis. Obyte isn’t included in the list, because it isn't directly compatible with Ethereum, but we’ll get there below. Besides the most basic functions, another key feature of MetaMask is its ability to connect you to Dapps. Whether you're interested in decentralized finance platforms (exchanges, lenders, liquidity mining, etc.), Non-Fungible Token (NFT) marketplaces, or decentralized games, this wallet could serve as a gateway, allowing you to interact with these platforms without abandoning the app in most cases. MetaMask + Obyte We can say that MetaMask is the first bridge between Obyte and other decentralized networks. As you may know, Obyte has its own wallet to store, send, and receive funds, chat privately, and access Dapps and chatbots within its own ledger. However, some Dapps are meant to connect to the outside crypto world, and users will need a MetaMask wallet for that. We’ll look into three of them. Counterstake Bridge This is a cross-chain bridge in Obyte, which means it works to exchange Obyte-based tokens for an equivalent in external networks (export) or bring external tokens into the Obyte network (import). This way, you could, for instance, exchange some GBYTE on Obyte (from the Obyte wallet) for GBYTE on Ethereum (to MetaMask), or ETH on Ethereum to ETH on Obyte. In both cases, your address or payment in MetaMask will be required. LINE Token This is a price-protected token based on Kava but meant to be borrowed and bridged into Obyte to earn rewards. You can use KAVA, Tether, or Kava-based GBYTEs (Obyte native coin) to borrow LINE, all of them from MetaMask. Decentralized Exchanges Obyte has its own DEX, Oswap.io, but it only works with Obyte-based assets. To trade with other networks, these assets should pass first through Counterstake and land on MetaMask. Once there, you can use external DEXes like Quickswap to exchange, for example, some Polygon-based GBYTEs for Tether (USDT). So, MetaMask and Obyte, although different, can work together to enhance your experiences in the crypto world. Bridges like Counterstake enable seamless asset exchanges between them, expanding possibilities for users by connecting two distinct ecosystems and leveraging the strengths of both.

Last week, the SEC filed a suit against Consensys, the developer of the popular MetaMask wallet. The SEC claims that Consensys, which “markets itself as a leader and innovator in the crypto asset industry”, was offering products that performed age-old functions. These products include brokering securities transactions for retail investors and engaging in the offer and sale of securities. According to the SEC, Consensys should have registered as a broker, as well as registered the offer and sale of certain securities. The SEC is focused on going after MetaMask Swaps and MetaMask Staking services. This is not the first time the SEC has accused staking services of violating securities laws. Back in 2023, the SEC sued Coinbase and Kraken. Meanwhile, the well-known case against Binance involved multiple allegations and ultimately put Binance’s founder CZ in jail. Kraken’s case is illustrative. The management of the crypto exchange decided that it was futile to oppose the regulator. As a result, Kraken stopped offering its staking-as-a-service program for U.S. users. The service is still available for customers in other countries. Kraken’s settlement with the SEC also involved payment of $30 million in disgorgement, prejudgment interest, and civil penalties. Apparently, Consensys believes that it is in a better position compared to Binance or Kraken. The company has previously sued the SEC in a preventive effort to stop a potential suit against Consensys. As we know now, this attempt has failed, and the regulator proceeded with its own lawsuit against the company. Consensys' lawsuit centered on the classification of ETH, arguing that it should be recognized as a commodity rather than a security. The company emphasized that Ethereum is a global computing platform, not an investment scheme. Consensys expressed concerns about the potential designation of ETH as a security, given MetaMask's pivotal role in the ETH ecosystem. Taking a look at last year’s cases of Binance, Coinbase, and Kraken, it is obvious that the SEC does not plan to destroy the whole industry or any single coin. Such a plan is impossible both technically and politically as the crypto industry has gained strong momentum and coins have found their place in portfolios of multiple investors of any level, from retail guys to institutional pros. The regulator uses lawsuits to get more control over the industry and slow down its development. However, things are not always going in the SEC's favor. In the case of SEC vs Ripple, the regulator has mostly lost the case. The court found out that Ripple violated securities laws when selling XRP to institutional investors but dismissed other charges brought by the regulator. In this light, Consensys should have a decent chance for a long and complicated court battle against the SEC. Potentially, the company may try to wait for the changes in the SEC leadership, hoping that new people will be more crypto friendly. Talking about ETH, its holders have nothing to worry about. As usual, the case might generate some FUD on Ethereum, which is typical for the industry. Last week, the SEC filed a suit against Consensys, the developer of the popular MetaMask wallet.

SEC vs MetaMask: Is Staking Is Under Fire Again?

Cryptocurrency and blockchain technology are becoming increasingly popular, but getting started can be intimidating. One essential tool for anyone looking to explore decentralized finance is MetaMask. This browser extension allows users to interact with the Ethereum blockchain easily and securely. What is MetaMask? MetaMask is a cryptocurrency wallet that runs as a browser extension. It works with Chrome, Firefox, and Edge and allows users to store and manage Ethereum-based assets like ETH and ERC-20 tokens. With MetaMask, you can send and receive cryptocurrencies, use decentralized applications, and access the world of Web3 directly from your browser. A key advantage of MetaMask is that it functions as a "light client." This means you don't need to download the entire Ethereum blockchain to start using it. MetaMask handles all the complex backend interactions for you. Setting Up a Wallet Getting started with MetaMask takes just a few minutes. Download and install the extension for your browser: When you first open it, you'll go through an initial setup process: Create a password Save your secret recovery phrase (12 random words). This phrase gives you access to the wallet if you ever lose access. Accept the terms of use Once your wallet is set up, you'll get an Ethereum address that starts with "0x". This public address allows you to receive funds and interact with smart contracts. For security, it's crucial to keep your recovery phrase and private keys safe. Never store them digitally in plain text. Write them down on paper and keep them somewhere secure. Using MetaMask The main MetaMask interface shows your account balance, transaction history, and options to buy, send, and swap tokens: To receive funds, simply share your public wallet address. Then transactions will show up automatically in your history. You can customize MetaMask to use test networks like Ropsten and Goerli. These allow you to experiment without paying real gas fees. Faucets like provide free test ETH on testnets. Goerli Faucet With your wallet set up, you can start exploring DeFi apps, games, markets, and more! MetaMask makes Web3 accessible. What is a Transaction? A transaction is a message sent over the network that changes address balances. For example, transferring currency deducts from one address and adds to another. Transactions have a unique hash. Their status can be: Pending - Not yet processed Success - Added to the network Fail with error - Rejected The sender, receiver, amount, and gas fee are shown. Gas is paid in Gwei, equal to a billionth of an Ether. Exchanging Currency A sample exchange contract is used to swap Ether for USDT, a stablecoin pegged to USD. On Etherscan, the MetaMask wallet is connected to use the contract's function. swapEthForUsdt After confirming, the USDT balance changes in MetaMask. The Etherscan page acts as a receipt for the transaction. Key Takeaways MetaMask is a crypto wallet browser extension used to manage Ethereum assets. It allows you to access Web3 DApps directly from your browser. Set up only takes a few minutes. Be sure to save your recovery phrase securely. Use test networks like Ropsten and Goerli to try things out without fees. Your public wallet address lets you receive crypto and interact with smart contracts. MetaMask opens up the world of decentralized apps and finance. With just a simple browser extension, anyone can now access Web3 and become part of the blockchain ecosystem. Conclusion We have learned to use MetaMask for transferring, receiving, and exchanging cryptocurrency. Next, we will explore smart contracts in more detail.

You’ve probably heard that Generative AI has demonstrated the potential to disrupt a huge number of industries and jobs — and web3 is no exception. But how well can ChatGPT create smart contracts? Can using ChatGPT to code smart contracts make you a 10x developer? In this article, we’ll try it out and see. We’ll walk through writing and deploying an Ethereum smart contract using , , and … and we will ask ChatGPT for instructions on how to do everything from the code to the deployment. MetaMask Infura Truffle The goal is to see if we can break down the task of creating a smart contract into a set of simple prompts. Ideally, ChatGPT can parse those prompts and give good (and accurate) answers to them, making us a faster, and better, developer. Let’s see what we can do! A Note on Accuracy ChatGPT is a Large Language Model (LLM) extremely proficient in explaining blockchain concepts, providing advice, and even generating code snippets related to web3 development. However, keep in mind that some of the code or answers it generates may be partially or completely incorrect. Access to ChatGPT does not remove the need to know the basics of blockchain development. However, even a beginner can use artificial intelligence to dramatically increase productivity. The second point to note is that the free, public version of ChatGPT isn’t very aware of events, updates, and practices that have emerged after 2021. This can be an issue in a field such as web3 development, where everything is improving and changing at a breakneck pace. However, it is possible to get good answers if something that you’re asking is fundamental and has been stable over the years (for instance, Truffle and Solidity). Create an Escrow Contract with Truffle and ChatGPT To see what ChatGPT can do, we’re going to ask it to create an escrow smart contract that allows a buyer and a seller to exchange money, and we’ll have ChatGPT establish an arbiter to resolve disputes. Let’s see what Generative AI can do! Step 1: Install MetaMask First we need to set up a wallet. We’ll use wallet — the most popular Ethereum option — and add the Sepolia test network. MetaMask is secure and easy to use. MetaMask You can download the MetaMask extension for your browser . Then, just install and set up the wallet. You’ll be given a “secret phrase” — keep this private and safe! Never store it anywhere public. here Note: If you need background or a primer on web3, check out this on learning web3/smart contracts/Solidity. previous article I wrote Next, click on the “Network” tab in the top-right. Click on the option to show test networks. You should now see the Sepolia test network in the dropdown. Select that. Step 2: Get SepoliaETH To deploy and interact with a smart contract, you need ETH. Since we are using the Sepolia test network, we’ll need to get some Sepolia test ETH. Don’t worry — it’s free! You can obtain free SepoliaETH from Infura’s recently released faucet . This faucet gives up to 0.5 SepoliaETH each day for free. here Step 3: Install Node and NPM In order to build an escrow system using Truffle, we will need . Node and NPM To check to see if it’s installed, run: $ node -v You should see the Node version. Step 4: Sign Up for Infura Infura is an RPC provider. They provide easy API-based access to everything we need to connect to—and work with—the Ethereum blockchain (and quite a few others). Sign up for a free account . Then go to the and select Create New Key. here dashboard Choose Web3 API as the network and name the new key Escrow (though you can name it whatever you want). Click Create, and Infura will generate an API key. This key is what you need to access your RPC endpoint. For our purposes, we just want the Sepolia endpoint. https://sepolia.infura.io/v3/<your API key> Step 5: Create the Node Project Next we need to create our Node project and then complete our setup with any necessary packages. $ mkdir escrow && cd escrow
$ npm init -y To deploy and test our contract, we’ll use Truffle. Truffle is a suite of tools that give you everything you need to develop, test, and deploy smart contracts. Let’s install it: $ npm install —save truffle You can create a project skeleton using Truffle by running: $ npx truffle init To check that everything ran correctly: $ npx truffle test We now have Truffle successfully configured. Let’s next install the OpenZeppelin contracts package. This package will give us access to a few more helpful functionalities that we may require. $ npm install @openzeppelin/contracts We’re almost done with the setup! Next we have to allow MetaMask and Truffle to work together. We need Truffle to be able to sign transactions, pay gas, etc. For this we’ll use . Install it: hdwalletprovider $ npm install @truffle/hdwallet-provider And finally, let’s use to keep our wallet information secure. dotenv $ npm install dotenv Step 6: Sign Up for ChatGPT We won’t be writing the escrow smart contract code from scratch. Instead, we’ll see what ChatGPT can do. In order to use ChatGPT, with OpenAI. sign up for a free account Once you’ve signed up for an account, visit . You should see an interface that looks something like this: this page Step 7: Create the Escrow Contract Next, we’ll have ChatGPT create an extremely simple escrow contract that allows a buyer and a seller to exchange a certain amount of money, and an arbiter to resolve disputes. Let’s use the following prompt in ChatGPT. `As an expert smart contract developer, create a smart contract using Solidity that implements an escrow. There will be three parties: the buyer, the seller, and the arbiter. The constructor will set the buyer, seller, and arbiter. It will also set the value which will be equal to the amount sent to the constructor. There will be two functions. The first function allows the buyer or the arbiter to release funds to the seller. The second function allows the buyer or the arbiter to refund the amount back to the buyer. Implement any other functions that you may think are relevant.` Note the “As an expert smart contract developer” beginning of the prompt. This type of “role playing” with ChatGPT works very well. Now ChatGPT will generate a unique response for you. And this response will change every time. So you may not get the same output that is shown below, but it should be something similar. Sure, here's an example implementation of an escrow smart contract in Solidity: pragma solidity ^0.8.0; contract Escrow {
address payable public buyer;
address payable public seller;
address public arbiter;
uint public value;
bool public released;
bool public refunded; constructor(address payable _buyer, address payable _seller, address _arbiter) {
    buyer = _buyer;
    seller = _seller;
    arbiter = _arbiter;
    value = msg.value;
}

function release() public {
    require(!released, "Funds have already been released.");
    require(msg.sender == buyer || msg.sender == arbiter, "Only buyer or arbiter can release funds.");
    released = true;
    seller.transfer(value);
}

function refund() public {
    require(!refunded, "Funds have already been refunded.");
    require(msg.sender == buyer || msg.sender == arbiter, "Only buyer or arbiter can refund funds.");
    refunded = true;
    buyer.transfer(value);
}

function getBalance() public view returns (uint) {
    return address(this).balance;
}

function setArbiter(address _arbiter) public {
    require(msg.sender == arbiter, "Only arbiter can set arbiter.");
    arbiter = _arbiter;
}

function setSeller(address payable _seller) public {
    require(msg.sender == seller, "Only seller can set seller.");
    seller = _seller;
} } The `Escrow` contract has a constructor that takes three arguments: the addresses of the buyer, seller, and arbiter, and sets the `value` equal to the amount sent to the constructor.

The `release()` function allows the buyer or the arbiter to release the funds to the seller. It first checks that the funds haven't already been released, and that the caller is either the buyer or the arbiter. If both conditions are met, the `released` variable is set to `true`, and the `value` is transferred to the seller's address.

The `refund()` function allows the buyer or the arbiter to refund the funds back to the buyer. It first checks that the funds haven't already been refunded, and that the caller is either the buyer or the arbiter. If both conditions are met, the `refunded` variable is set to `true`, and the `value` is transferred back to the buyer's address.

The `getBalance()` function returns the balance of the contract.

The `setArbiter()` function allows the arbiter to set a new arbiter.

The `setSeller()` function allows the seller to set a new seller.

Note that this is a very basic implementation of an escrow contract and should not be used in production without thorough testing and auditing. Also, there may be additional features that you may want to add to suit your specific use case. Upon inspection, the snippet provided by ChatGPT is pretty good! But it does have an error—the constructor is not marked even though we’re accessing and expecting Ether to be sent to it. payable msg.value Again, an important note: Never expect ChatGPT to give you code that is 100% correct. More often than not, you will have to make small corrections like we did here. Also notice that ChatGPT uses an earlier version of Solidity, and it uses a practice of fund transfer that is not considered best practice anymore. For the purpose of this tutorial, we’ll just let it be. In the contracts folder of your project, create a new file called and add the code provided by ChatGPT with the corrections. Escrow.sol // SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;

contract Escrow {
    address payable public buyer;
    address payable public seller;
    address public arbiter;
    uint public value;
    bool public released;
    bool public refunded;

    constructor(address payable _buyer, address payable _seller, address _arbiter) payable {
        buyer = _buyer;
        seller = _seller;
        arbiter = _arbiter;
        value = msg.value;
    }

    function release() public {
        require(!released, "Funds have already been released.");
        require(msg.sender == buyer || msg.sender == arbiter, "Only buyer or arbiter can release funds.");
        released = true;
        seller.transfer(value);
    }

    function refund() public {
        require(!refunded, "Funds have already been refunded.");
        require(msg.sender == buyer || msg.sender == arbiter, "Only buyer or arbiter can refund funds.");
        refunded = true;
        buyer.transfer(value);
    }

    function getBalance() public view returns (uint) {
        return address(this).balance;
    }

    function setArbiter(address _arbiter) public {
        require(msg.sender == arbiter, "Only arbiter can set arbiter.");
        arbiter = _arbiter;
    }

    function setSeller(address payable _seller) public {
        require(msg.sender == seller, "Only seller can set seller.");
        seller = _seller;
    }
} Make sure the contract is compiling correctly by running: $ npx truffle compile Step 8: Update Your Truffle Config Next, we’ll do a little configuring without ChatGPT. This is a standard setup and will depend on the environment we’re using. Create a new file in your project’s root directory and add the following: .env INFURA_API_KEY = "https://sepolia.infura.io/v3/<insert API key here>"

MNEMONIC = "<insert metamask secret phrase here>" Now let’s configure the Infura endpoint. In replace the existing code with this standard config: truffle.config.js require('dotenv').config();
const HDWalletProvider = require('@truffle/hdwallet-provider');
const {INFURA_API_KEY, MNEMONIC} = process.env;

module.exports = {
    networks: {
      development: {
        host: "127.0.0.1",
        port: 8545,
        network_id: "*"
      },
      sepolia: {
        provider: () => new HDWalletProvider(MNEMONIC, INFURA_API_KEY),
        network_id: '11155111',
      }
    }
}; Step 9: Deploy the Contract Now it’s time to deploy! Instead of giving you the script to deploy our contract using Truffle, let’s ask ChatGPT for the relevant instructions. In the same window that you used to ask for the escrow contract code, we’ll enter the following prompt: Give me a migration script that deploys the Escrow contract using Truffle. . I need to send 0.001 ETH to the constructor during deployment. And I need the address that deploys the contract to be the buyer We get this response: Sure, here's an example migration script that deploys the `Escrow` contract and sends 0.001 ETH to the constructor during deployment. In this script, the address that deploys the contract will be set as the buyer.

1. Create a new JavaScript file named `2_deploy_escrow.js` (the number at the beginning indicates the order in which the migrations will be executed).
2. Copy the following code into `2_deploy_escrow.js`: const Escrow = artifacts.require("Escrow"); module.exports = async function(deployer, network, accounts) {
const buyer = accounts[0]; // set the buyer as the address that deploys the contract
const seller = "0x2222222222222222222222222222222222222222"; // replace with seller address
const arbiter = "0x3333333333333333333333333333333333333333"; // replace with arbiter address
const value = web3.utils.toWei('0.001', 'ether'); // change to the value you want to send await deployer.deploy(Escrow, seller, arbiter, { from: buyer, value: value });
}; 3. Replace the seller and arbiter addresses with the actual Ethereum addresses of the parties involved in the escrow transaction.
4. Save the file.
5. Make sure you have a network configured in your `truffle-config.js` file. If you want to deploy to a testnet, you'll need to configure your Truffle project to use the network you want to deploy to.
6. Run `truffle migrate --network <network-name>` to deploy the contract to the specified network. Replace `<network-name>` with the name of the network you want to deploy to, e.g. `ropsten` for the Ropsten testnet. This will deploy the contract and send 0.001 ETH to the constructor with the address that deploys the contract set as the buyer. Once again, the instructions provided by ChatGPT are mostly correct. It gets the naming wrong (we want it to be prefixed with 1_ and not 2_) and makes a minor mistake in setting the arguments of the function. deploy Let’s create a new file in the folder. Add the following, slightly modified code. 1_deploy_contract.js migrations const Escrow = artifacts.require("Escrow");

module.exports = async function (deployer, network, accounts) {
    const buyer = accounts[0]; // set the buyer as the address that deploys the contract
    const seller = accounts[1]; // replace with seller address
    const arbiter = accounts[2]; // replace with arbiter address
    const value = web3.utils.toWei('0.001', 'ether'); // change to the value you want to send

    await deployer.deploy(Escrow, seller, arbiter, { from: buyer, value: value });
}; And finally, let’s deploy our contract: $ truffle migrate --network sepolia You should see something similar to this: Compiling your contracts...

And you did this using ChatGPT to generate more than 95% of your code. Tips and Tricks Here are a few tips and tricks for using ChatGPT when coding: ChatGPT has limited knowledge and has a knowledge-base cutoff of September 2021. So some of those best practices and latest developments in smart contracts are going to be missing from its knowledge. There are several versions of ChatGPT. GPT-4 tends to give better answers, but is a paid service. GPT-3.5 (which we used here) is free, and does pretty well. Make your questions as specific as possible. Don’t stop with writing code. ChatGTP can debug your code, audit it, document it, make it pretty, analyze it, find vulnerabilities, and more. Conclusion ChatGPT was an extremely useful co-developer. But it wasn’t perfect. I wouldn’t use it to create unmodified code that I pushed to mainnet—especially if I was a newdeveloper. But as a coding partner, and as a place to start, it was helpful. It saved me significant time and created surprisingly good code. In the hands of an experienced developer, I believe it can increase productivity by many times. I plan on using it quite heavily on future projects, alongside MetaMask, Infura, and Truffle. Have a really great day!

While you can earn a lot from investing in crypto assets, there are also risks you’ll have to manage if you are to protect your earnings. Security lapses give hackers opportunities to loot people’s assets. What to do if your wallet gets hacked? You’ll find out in this post. Metamask More than 20 million people around the world store and safeguard their cryptocurrencies in Metamast wallets. This makes it a major target for thieves. If you check your wallet one day and discover that unsanctioned withdrawals were made from your account, it's likely that you have been hacked. This post is about the steps you should take when notice that your MetaMask wallet has been hacked, and how to prevent its recurrence. My MetaMask Just Got Hacked If you realize that hackers have gained access to your or suspect attempts to hack into it, your response must be rapid. Metamask account Your main priority and the first step you should take is to protect your remaining investment from the attackers. Reach out to the MetaMask support team immediately and inform them that you suspect you have been hacked. How do you secure your remaining funds? You have to transfer all of them out of the compromised wallet to a secure one if you have more than one wallet. You must create an alternative wallet if you don't already have one. The new wallet could be another MetaMask account or a different wallet entirely like a Trust wallet. The new account or wallet must be created with an email account different from the one you used to create the compromised wallet. This is because your attackers could have accessed your wallet from security lapses in your email. Besides using a fresh email account, you must use a different device from the one that got hacked. This is because some hackers gain access to your device and wallet by tricking you into installing malware. They then use this to get information about your login details and seed phrases. If you use the same device despite the malware it is injected with, the subsequent accounts you'll create will remain vulnerable to hackers. The malware/spyware they've embedded in your device will still detect the login details of the new accounts you create, and then serve the data to the hackers. And the cycle continues. To clean your device and prevent future attacks, you'll need to use an efficient malware cleaner to rid your system of the injected malware. Don't use the most common free antivirus software for this as they aren't capable of mitigating these threats. Just invest some money in a premium malware cleaner to wipe your system of this harmful software. After you've created a new MetaMask account, using a new email, in either a fresh device or a device already cleaned of all malware, move your remaining funds from the old account to the new one. This will protect you from losing everything. If you're unlucky and the hackers have changed the login details of the old account and lock you out, then your funds are gone for good and the probability of regaining them is negligible. After moving your funds out of the compromised account, do not use it again. The Bitter Truth About a MetaMask Hack One unpleasant fact about hacks, including MetaMask, is that it is crypto wallet almost impossible to recover stolen funds. One of MetaMask's disclaimers is the warning that "transactions cannot be reversed". Even if it is confirmed that indeed you were hacked, the funds cannot be recovered. And they make it clear that they can't be held liable if your account is hacked. Taking safety measures like moving out the remaining funds, if any, might not return your stolen investment, but it will save you from further exploitation. However, you can provide adequate information to MetaMask support to see if your funds can be tracked. Since a hack or cyberattack is basically an unauthorized person gaining access to your wallet and making withdrawals you did not approve, at least you can track the destination of your funds. Informing MetaMask will enable them to check the details of the receiving account in their database and block further attempts of the attackers to repeat similar withdrawals in the future. Measures you can take to protect your cryptocurrency investments. There are many wolves in the crypto space, ready to pounce on privacy breaches to empty people's wallets. Protecting your privacy details must be prioritized so that a random criminal won't gain access to your wallet. Here are some of the steps you can take to maintain the security of your crypto wallets: . This includes the username and password you use, the email account connected to it,  or the seed phrase for the device. (Seed phrase is a secret group of words used to log in and recover accounts ). Never share your MetaMask wallet information with anyone or any organization . Ensure you do not use a password you use for other apps or passwords related to your name or date of birth, which can easily be guessed. Change your password occasionally or other unsecured networks. This makes it susceptible to malware attacks and hacking. Never use the MetaMask app or website while connected to public WiFi , or let others log in with your device. Don't use someone else's device to log into your MetaMask When you are not actively using the app, so another person doesn't gain access to it. remember to log out If you use Chrome or any other browsers' s extension for accessing your MetaMask account, remember to delete your browsing history and to clear your cache. These precautionary measures are easy to understand but a lot of people fail to follow them. You don't always need high-tech solutions to protect your account. Following these simple safety rules will keep your wallet safe. Advanced Tips to Prevent Being Hacked Again While we can always try our best to protect our digital wallet and safeguard our investment, there is still a possibility of fraudsters gaining access to it.  Below are measures and precautions recommended by MetaMask for keeping your wallet safe: , or initiate a conversation. Any unsolicited message from someone claiming to be a MetaMask staff member should be treated with caution. Don't respond carelessly, or not at all. Some types of spyware gain access to your wallet when you respond to their messages. No MetaMask member of staff or admin will send you a message first This private information must never be shared with anyone. There is no MetaMask admin that will require you to visit another website or redirect you to another website where they prompt you to download another app that requires your seed phrase. If this happens, someone is trying to hack your wallet. If you're browsing and you see a pop-up on your screen requesting for your sensitive information like password or seed phrase, ignore it and close the tab. The email domain is "metamask.io" and must be visible in the sender's address. If the message comes from a different domain asking you to download a file or click some buttons, NEVER click on it as it might be a phishing link. Just delete the email. When MetaMask communicates with its users concerning software or security updates, their emails follow recognizable templates. Do not get greedy and follow their advice, just report to MetaMask admin and then delete. This type of scam often works on greedy people who want to send small funds and receive more. One of the most common scopes used by crypto scammers is to ask you to send funds to a wallet's address, so you can receive more funds. If a deal or proposition sounds too good to be true, it probably is. Scammers often trap their victims by proposing returns with high yields and zero risks. Ask yourself if this is possible. Always question people's motives, skepticism is a protective shield in this industry. If you don't know why you are receiving a message, it might be a scam attempt. The paranoid survive. Always be security conscious about your crypto assets. Whenever you use crypto apps, follow the established security protocol religiously. The more consistently you do this, the lower the risk of your getting scammed. Some might be in a rush to complete a crypto task and then cut corners which leaves openings for fraudsters to exploit. Don't be like that. If you have any other security tips, or updates you'd want to share, drop them in the comment section.

Introduction Do you want to test your Ethereum smart contracts without having to worry about running out of ethers? We'll show you how to add as many free Ethers as you like to your Metamask wallet in this guide. By using this technique, you can have a plentiful supply of ethers available for use in testing and development. You only need NodeJs, the Chrome extension for Metamask, and a few easy steps. Don't miss out on valuable insights into the world of Web3 development! , you'll have access to a wide range of educational videos that can help take your skills to the next level. And if you're interested in connecting with me personally, be sure to , and I offer. Join me on this exciting journey of Web3 development and let's unlock its full potential together! By subscribing to my channel check out the books, courses services Prerequisites To follow this tutorial and load free ethers into your Metamask, you will need the following packages: NodeJs Metamask Chrome Browser You can watch the video tutorial with the YouTube video below. https://www.youtube.com/watch?v=qnudOwva0fM&embedable=true Now let’s take a look at the steps and methods you will need to load unlimited free ethers to your Metamask wallet. Hardhat Method Because of its flexibility, extensibility, and speed, many web3 developers and web3 professionals alike have adopted Hardhat as the go-to framework for developing applications on the Ethereum network. Here are the steps to load Ethers to Metamask using Hardhat. Create a project named , this could be any JavaScript-based project such as NodeJs, ReactJs, VueJs, or even a NextJs project. For this example, we will do a NodeJs project. STEP 1: Setting Up Project Structure **freeTestEthers** Next, open the project folder on the terminal or simply navigate to that directory and run the following commands. cd freeTestEthers
npm init --y The above command will initiate the folder as a nodeJs project. See the image below. Install the Hardhat packages that enable you to run a blockchain server, on the terminal, run the following commands: STEP 2: Creating Hardhat Project npm install hardhat After the installation, run the hardhat command below. npx hardhat Now, follow the promptings as can be seen in the image below to complete the installation: On completion of the installation, again run this command to spin up the Hardhat blockchain server: STEP 3: Running Hardhat Server npx hardhat node The above command should spin up a server looking like the one in the image above. Please observe the difference between the accounts and their private keys. We will later use the private keys to import Ethers to Metamask. With Metamask already installed, open your browser and visit the following link which will open up your Metamask extension interface in full. It should look like the image below. STEP 4: Accessing Metamask chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/home.html# STEP 5: Configuring Network We now tell Metamask to use the Hardhat server running on step 3 of this section. Metamask normally comes with a Localhost network by default which has Hardhat configured, so we wouldn’t need to set up the network from scratch. Head to the networks page of Metamask and ensure that your setup is on the same page as mine. Did you notice the network configuration in the image above? Refers to the alias you prefer giving to your blockchain network. Network Name: Points to the HTTP endpoint where the blockchain service can be accessed from, it comprises the host and port of the blockchain server. New RPC URL: Specifies a unique identification number for a particular blockchain network, for the Hardhat server, it is always 31337. Chain Id: Indicates the kind of cryptocurrency used in a particular blockchain network. Currency Symbol: From step 3, copy the first private key for the account zero (0) as can be seen in the following image. STEP 6: Importing Accounts Now, ensure that you select Localhost as your preferred network and click on the “ ” button as can be seen in the image below. import account Congratulations, you have been able to import a new account using its private key, now compare how through the private key account 5 address is the same as the one in the image below. You can now repeat this process to import more accounts from your Hardhat server. With this one-time process implemented, anytime you spin up your Hardhat blockchain server, your account will be updated with a fresh 10,000 ETH balance. You can now use all these Ethers for your Hardhat development processes. Ganache Method Truffle is one of the most comprehensive suites of tools for smart contract development. For a blockchain server, they have Ganache. With Ganache you don’t need to install it on a specific project, you just need to set it up globally one time on your Local machine. Here are the steps to load Ethers to Metamask using Ganache. To Install Ganache globally on your machine, run the following command on your terminal: STEP 1: Installing Ganache Server npm install ganache --global //or
sudo npm install ganache --global After the installation, you should see a result similar to the image below. On completion of the installation, run the command below to spin up the Ganache blockchain server: STEP 2: Running Ganache Server ganache -d A server that resembles the one in the image above should be created using the aforementioned command. Please pay attention to how the accounts and their private keys differ. The private keys will eventually be used to import Ethers into Metamask just as we did with Hardhat. Once more, we must instruct Metamask to connect to the Ganache server that is active in this section's step 3. This time, a brand-new network will be added from scratch. STEP 3: Configuring Network Verify that your configuration is on the same page as mine on Metamask's networks page. Now it should be known that the only difference between Hardhat and Ganache servers is their chain Id. While Hardhat has a 31337 chain id, Ganache has 1337. Ensure that you click the save button to add it to your network list. From step 3, copy the first private key for the account zero (0) as can be seen in the following image. STEP 4: Importing Accounts Now, ensure that you select Localhost as your preferred network and click on the “ ” button as can be seen in the image below. import account Congratulations, you have been able to import a new account using its private key, now compare how through the private key account 5 address is the same as the one in the image below. You can import accounts into your Metamask wallet in this manner. Doing this procedure now will allow you to import more Ganache server accounts. After completing this one-time procedure, every time you power up a Hardhat blockchain server, your account will be updated with a new balance of 1,000 ETH. All of these Ethers are now available for usage in your Hardhat development procedures. Don't miss out on the opportunity to become a sought-after smart contract developer! , and gain the skills and knowledge you need to excel in this exciting field. And while you're at it, be sure to to stay up to date with the latest web3 development videos. Get your hands on a copy of my book, "Capturing Smart Contract Development" subscribe to my channel Conclusion In conclusion, this guide offers two methods, the Hardhat and Ganache methods, to add unlimited free Ethers to a Metamask wallet for testing and development purposes. Both methods require the installation of NodeJs, the Chrome extension for Metamask, and the use of either the Hardhat or Ganache framework. By following the steps outlined in the guide, users can easily load Ethers onto their Metamask wallet and have a plentiful supply available for testing and developing Ethereum smart contracts.

Internal JSON Error, a 32603 error, is the most common and significant error that occurs on MetaMask. It happens for various reasons. If Internal JSON 32603 error appears, it means the MetaMask is having some difficulty detecting the error. In this article, we are sharing 5 best practices and 8 possible solutions that can help you solve the internal JSON 32603. Before I get started, I would like to explain a bit about JSON and JSON RPC. What is JSON? JSON is famous for being a lightweight format that can transfer data faster than its competitors. JSON’s full form is JavaScript Object Notation, which breaks the data in the format until it becomes easy to process. As JSON is JavaScript based, you will find different variables like strings, objects, boolean, and null characters while you try to understand its data element. As JSON helps to process data easily, the data is mapped into a manageable structure that allows different programming languages. JSON was originated in the year 2000 by Douglas Crockford, and thus, it encourages server communications and Web applications. What is JSON RPC? JSON RPC is a progression of a JSON, and globally, JSON RPC is identified as a Remote Procedure Calling (RPC) protocol. JSON RPC is a new protocol with a narrow scope. It brings diverse data structures into action by defining tasks for application by working at the development level. It is an ideal pick for developers for rapid development or uncomplicated things. Moreover, JSON RPC comes with the following 4 pointers - It reflects data processing-related limitations over a network. As it is lightweight and processes the data faster, those 2 features make it suitable for Ethereum nodes. JSON-RPC protocol can utilize HTTPS and sockets for interacting. JSON RPC protocols are the best option for developing Ethereum-based solutions. Further, JSON RPC has 2 specifications, JSON RPC 1.0 and JSON RPC 2.0 - JSON RPC 1.0 was a peer-to-peer communication method. And, it lacked name parameters and explanation of error messages which caused more trouble. Another updated and highly advanced specification, JSON RPC 2.0, solved the problems of the previous version 1.0. The updated version includes error details along with additional extensions. Internal JSON RPC 32603 error on MetaMask - If you are getting Internal JSON-RPC Errors while interacting with other networks, then the below pointers can help to solve your problem - Make sure that you have added the network correctly. You can even use to add your custom network or even tokens. Chainlist Make sure you hold enough native tokens to pay the gas fees. Make sure you are using MetaMask’s latest version extension. Internal JSON RPC error with the Custom network or sidechains - Internal JSON RPC error while interacting with the sidechains or custom network, here is the detailed guide for you to solve your internal errors - A custom network or a sidechain is a technology that supports and is compatible with the Ethereum Ecosystem. It allows users to transfer crypto assets/tokens between different networks. MetaMask has been essential for the Ethereum Ecosystem, allowing users to move between networks. Moreover, there are some common problems when dealing with the sidechains which you should avoid. And we will provide 6 best practices required when dealing with sidechains. The following guidelines are general guidelines. 5 best practices for Sidechains and Custom Networks - Not all custom networks are safe because they offer cheaper and faster transactions; they come with reliability guarantees and different security as compared to mainnet. Analyze the risks before moving to custom networks. 1. Do your Verification - You must have trust in the network provider because a malicious network provider may record your IP address and network activity and lie about the blockchain withholding transactions and affecting the state. You can find the network on Chainlist, which you can add further in MetaMask automatically. You can even add the network to MetaMask Manually, but it is not recommended until you are a Software Developer. You can add a manually in the MetaMask. 2. Ensure that you hold accurate custom network information - custom network Make sure that you verify the information of the custom network. You can go through this “ ” to understand more about the custom network and analyze it. Verification Guide MetaMask does not track transactions between different networks. You need to understand how different networks work for transactions. You must ensure you trust the network operator and any Ethereum address to which you send your funds. 3. Make use of established bridges to move tokens between different networks - If you attempt to send your tokens from one network/chain to another network/chain, the result will most likely be permanent crypto asset loss. 4. Avoid sending tokens directly from one network to another - A custom network may be compatible with the Ethereum Ecosystem, but they are not the same as Ethereum Mainnet. You may have the same Ethereum address for all your crypto assets, but your crypto assets are specific to each network, and you will require permission from the custom network provider to move those crypto assets. To move your crypto assets, you will require a bridge or portal to transfer your assets from one network/chain to another. When you interact with a side chain network/non-Ethereum network, the transaction fees are always paid in the native cryptocurrency of the network. 5. Understand the usage of Gas on different networks - For example — On Binance, you must pay BNB for gas fees. You must hold enough native crypto tokens/assets for any transactions you want to work on. 8 Possible solutions to solve Internal JSON RPC 32603 error on MetaMask - The internal JSON RPC 32603 error occurs mainly while creating smart contracts, and this happens due to Ganache’s Gas Estimation. No, the problem can’t be solved by limiting the Gas Limitation, as it has been experimented with by numerous people and none have been able to do so. The bytecode runs properly on Ropsten and Rinkeby testnet, but the issue occurs while running the bytecode on Mainnet. Even the problem doesn’t get solved by changing the different .

8 Tips for Solving The JSON RPC Error In Metamask 

Not every day can you meet people like Joel Dietz, Founding Member of , Architect of MetaMask, and the Founder of MetaMetaverse. I sat down with Joel to chat about Web3 technologies, innovation, and our future as he sees it. Ethereum What's your current role and what do you like about it? I founded the , and am currently running it as CEO. I'm also the lead language designer of the __ __language and metaurl protocol. We believe we have the best secret sauce for uniting all metaverses and becoming the platform of choice for individuals, DAOs, and businesses in building their metaverse. We focus on the experience of the Web3 travelers, and engagement throughout their journey traversing our cosmic system with a narrative to give travelers purpose when initiating their launch sequence. In the past, I was a founding member of Ethereum and the founding architect of . I have over a decade of experience in Ethereum development, governance protocols, cryptoeconomics, and establishing legal standards for utility tokens at Harvard and MIT. MetaMetaverse metalambda MetaMask How and when did you get into programming? I was always a logical thinker. I think of myself more as a thinker, rather than just a programmer. I first started programming games, but later my research interests focused on the confluence of blockchain network topologies and swarm intelligence, especially how the principles within decentralized organizations can be used to fuel global innovation. I also worked on holonic philosophy, the evolution of jurisprudence, data-driven approaches to innovation, and smart city data architecture. What's your earliest memory of learning to code? Very long ago. I think I was about six years old and started with Qbasic, and this cool magazine called 3-2-1 contact that used to have basic programming challenges. Not to show my age, but I think nowadays a lot has changed within the sector. When Elon Musk achieves his dream of getting us to Mars, what technology do you think would be important on Mars and why? Well, once the dream becomes a reality the next step needed would be one of Horticulture, they say Martian soil has some nutrients which plants need to grow and survive. But because of Mars's extremely cold conditions, plants such as Watney's potatoes would need to grow inside a controlled environment. This technology might already be around to sustain this growth. Another important step would be transportation, outside of the obvious necessity of providing appropriate tech and science to have individuals being able to breathe air freely. What's a programming language that you would build EVERYTHING and ANYTHING in and why? I love metalambda because it is the first language oriented about generating your own metaverses, simulations, and virtual reality. MetaLambdas are cross-platform functions that accompany computational lifeforms such as anticipated by Von Neumann in his Universal Constructor Theory. What's something you think Software developers do not do enough of? I believe software developers nowadays need to focus more on QA, effectively making sure they read their own code and making sure it works in that scenario. Planning out the purpose of building that code is another one of major importance, rather than building it because it ‘ended up in your lap.’ Writing test coverage is another thing. For those who do not know what that is, it’s a technique that determines whether our test cases are actually covering the application code, and how much code is exercised when we run those test cases. Build it with integration in mind - this is of the utmost importance nowadays given flexibility and robustness are of the highest necessity. A solid life balance is significant. Honestly, more developers need to cut time away from their computers and enjoy life a bit. Sometimes individuals who are constantly coding become lost in their work, and mistakes become abundant. What is your least favorite thing about programming? This goes back to my previous answer, it’s very easy for programmers to become introverted, with lots of people ending up not understanding you. It ends up being easier for people with bad intentions to take advantage of you. That’s why a solid life balance is important. What’s a technology you’re currently learning or excited to learn? There are too many, time is the issue. Currently, I’m looking at Pickover, who has a list of esoteric languages, and, in general, I like these very obscure programming languages. Time travel 10 years into the past or 10 years into the future? What does technology look like? Give reasons for your answer. In my opinion, I feel as if Telepathy will be the new frontier for the future. Imagine having the element of a smarter, sharper AI connected to your mind, and having the possibility to manipulate 3D space. The implications of this would be incredible. I’ll also be chatting with Joel about metaverses in twenty years on stage during Badass Show, an edutainment talk show about Web3, that I’m launching as a host during on November 2nd. I can’t wait for hundreds of people to see the show live at WOW, and millions - online. WOW Summit Lisbon Learn more about the summit here.
