Although Ethereum has firmly established itself as the leading blockchain platform capable of running smart contracts, it isn’t without its defects. It has solved some of its problems, such as enormous energy consumption by switching to a proof-of-stake consensus protocol. However, scaling issues continue to exist. Ethereum has a low transaction throughput (approximately 15 transactions per second), slow transaction finality (around 1 minute), and at times high gas fees when the network is under strain. Avalanche is an independent blockchain platform designed to overcome some of the barriers to scalability mentioned above. In this article, we will explore what Avalanche is and its benefits compared to other blockchain platforms. We will also create an ERC-20 smart contract on Avalanche from scratch using Infura. What Is Avalanche? According to its website, Avalanche is the fastest smart contracts platform in the blockchain industry, as measured by time-to-finality. Unlike Ethereum or Bitcoin, Avalanche consists of several chains, each performing a specific task. The Avalanche network's three most important chains are the C-Chain, the X-Chain, and the P-Chain. The C-Chain is an EVM-compatible blockchain capable of running smart contracts. The X-Chain is responsible for token transactions. And finally, the P-Chain maintains consensus among subnets, arguably the most critical component of Avalanche. Through , Avalanche allows anyone to spin up their own instance of a blockchain within the ecosystem. Additionally, users can customize these blockchains to suit their own needs. These custom blockchains can use different consensus protocols (proof-of-work or proof-of-stake) and offer over 4,500 transactions per second without putting any additional strain on the rest of the network. Each one is a sovereign network that defines its own rules. subnets Subnets are one of the most unique features Avalanche offers. Not only can anyone build their own custom blockchain network as a subnet, each one is completely interoperable with the rest of the Avalanche network. This makes subnets a powerful tool for creating custom solutions, while still being part of a broader network. Benefits of Using Avalanche Through the usage of subnets and novel consensus protocols, Avalanche can provide the following benefits: Since there is no upper cap on the number of subnets that can be created, and subnets operate fairly independently, Avalanche can offer extraordinarily high tps rates. Theoretically Infinite Transactions Per Second Avalanche has the lowest time-to-finality in the industry, with transaction confirmation in under two seconds. Low Transaction Finality Avalanche uses proof-of-stake to secure its network, which makes it extremely energy efficient. It also allows validators without access to high-end GPUs to participate. Energy Efficient Over thousands of validators secure Avalanche. And unlike Ethereum or Bitcoin, a small number of pools do not control the vast majority of the network. Extremely Decentralized Creating an ERC-20 Token with Avalanche As mentioned earlier, the Avalanche C-Chain is entirely EVM-compatible. This means it's simple to port projects from Ethereum and other EVM-based chains onto Avalanche. It also means that the mature tools for Ethereum development like devnet, Truffle, and top API suite, Infura work natively to develop on Avalanche. In this section of the article, we will create an ERC-20 contract that implements a cryptocurrency on Avalanche. We will do so using Solidity, Infura, Truffle, and the Truffle Dashboard. Step 1: Install the MetaMask Extension Install the for your browser in case you haven’t already, and follow the instructions put forward by Metamask to create your wallet. MetaMask extension Step 2: Add Avalanche and Fuji Testnet to MetaMask By default, MetaMask comes configured with only the Ethereum mainnet and Goerli testnet. In order to add the Avalanche C-Chain, and the Fuji testnet, follow the instructions in . this document Step 3: Get AVAX from a Faucet Head over to the on the Avalanche website and request a free test AVAX for your wallet. If all goes well, you should see 2 AVAX in your MetaMask wallet. Fuji faucet page Step 4: Get Infura Avalanche / Fuji URL Before we start building the project, let’s get the endpoint we will use. Go to infura.io and either sign up for an account or login, then perform the following: Click on the button and create a new Web3 API project. Create New Key Navigate to the tab and scroll down to . Endpoints Avalanche C-Chain Switch the endpoint from to . MAINNET FUJI Copy the endpoint for future use in this project. Step 5: Install NPM and Node We will build our project using node and npm. In case you don't have these installed on your local machine, you can do so . here To ensure everything is working correctly, run the following command: $ node -v If all goes well, you should see a version number for node. Step 6: Create a Node Project and Install Dependencies Let's set up an empty project repository by running the following commands: $ mkdir my-crypto && cd my-crypto
$ npm init -y We will be using Truffle, a world-class development environment and testing framework for EVM smart contracts, to build and deploy our smart contract. Install Truffle by running: $ npm install -g truffle We can now create a barebones Truffle project by running the following command: $ npx truffle init To check if everything works properly, run: $ npx truffle test We now have Truffle successfully configured. Let us next install the OpenZeppelin contracts package. This package will give us access to ERC-20 implementations (the standard for fungible tokens and cryptocurrencies), on top of which we will build our contract. $ npm install @openzeppelin/contracts Finally, let us install the package that will allow Infura to sign transactions on our behalf using addresses derived from a 12- or 24-word mnemonic. We will use the mnemonic from our MetaMask wallet in step 1 for this purpose. hdwallet-provider $ npm install @truffle/hdwallet-provider Step 7: Writing the ERC-20 Smart Contract Open the repository in your favorite code editor (e.g. VS Code). In the folder, create a new file called . contracts MyCrypto.sol We are going to write a very simple ERC-20 contract that creates a token with an uncapped supply. We will also mint 100 tokens in our wallet. Add the following code to the file: // SPDX-License-Identifier: MIT
pragma solidity ^0.8.4;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyCrypto is ERC20 {

    constructor() ERC20("My Custom Token", "MCT") {
        _mint(msg.sender, 100 * 10 ** ERC20.decimals());
    }
} Step 8: Deploy the Smart Contract to Ganache & Fuji In order to deploy the contract to the Fuji testnet, we will require an RPC endpoint. Fortunately, Infura offers access to free, blazing-fast Avalanche C-Chain endpoints. Here’s where the endpoint URL we obtained in Step 4 will come in. Next, in the file, replace the contents of the file with the following: truffle-config.js const HDWalletProvider = require('@truffle/hdwallet-provider');
const INFURA_API_KEY = "<-- Fuji Infura API Key -->";
const MNEMONIC = "<-- MetaMask Wallet Mnemonic or Private Key -->";

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "*"
    },
    fuji: {
      provider: () => new HDWalletProvider(MNEMONIC, INFURA_API_KEY),
      network_id: '43113',
      gas: 4465030
    }
  },
  compilers: {
    solc: {
      version: "0.8.13",
    }
  }
}; Replace the placeholders in lines 2 and 3 with your Infura Fuji API key and MetaMask wallet's mnemonic respectively. (The latter is the string of 12 words given to you when you first set up your wallet.) Take care to never share this key or mnemonic publicly. Alternatively, you can use your wallet’s private key instead of the mnemonic. This is found in your MetaMask wallet’s tab when you click on . Account Details Export private key Let us ensure that the contract is compiled correctly by running: npx truffle compile If there are no errors, we are clear to deploy the contract. With our smart contract in place, we can now write a simple deployment script. In the directory, create a file called and add the following code: migrations 1_deploy_contract.js const myCryptoContract = artifacts.require("MyCrypto");

module.exports = function(deployer) {
   deployer.deploy(myCryptoContract);
}; Now, before we deploy to the Fuji network, we should ensure it will deploy without any problems. We can do this by first deploying our contract to a local Ganache blockchain instance. To get Ganache running, open up a new terminal and type the following command: ganache Now we can test deployment to Ganache by typing: npx truffle migrate --network development That should produce output in our console similar to this one: Now that we know our contract will deploy successfully, we are all set to deploy our contract to Fuji. From the terminal, run the following command: npx truffle migrate --network fuji If all goes well, your terminal will display the transaction hash and the address of the deployed contract on the Fuji network. Head over to and search for your contract address to view your contract. https://testnet.snowtrace.io/ Step 9: Add Your Token to MetaMask Now that our token exists on a real blockchain, we can add it to our MetaMask wallet. Switch the network on MetaMask to Fuji, and choose on the Assets tab. Here, you can import a custom token by entering the contract address of your token, the name, and the symbol. Import Token If all goes well, you should be able to see your token and a balance of 100 under the tab. Assets Conclusion In an extremely short amount of time, Avalanche has emerged as one of the most formidable alternatives to Ethereum and its ecosystem. Its network of subnets promises faster transactions and low costs at the same time. As evidenced by the token we created in this article, Avalanche uses the same tools Ethereum uses. Therefore, if you are an Ethereum developer, you are also an Avalanche developer by default. To start building on Avalanche using Infura, . check out the documentation here Have a really great day!

How To Deploy An ERC-20 Smart Contract On Avalanche with Infura

GitHub Repo:- https://github.com/PradhumnaPancholi/Figbot Hey everyone! A little while ago, I was learning as it has fantastic tools for developing and auditing smart contracts. And although I loved the experience, I soon learned that it is in the clandestine development stage. This means that casual/individual users can not depend on maintainers for support and updates. Dapp Tools Then I stumbled upon . It has everything that Dapp Tools offers apart from built-in symbolic execution (which is not a problem for me as I use e by Trail of Bits ). And this is auditing related hence not a hindrance in smart contract development by any stretch of the imagination. Foundry Manticor After working with Foundry for a bit, I enjoyed the experience and wanted to share that with others. Hence, this article. This article will go through the benefits of Foundry, the installation process,  developing an NFT (because everyone is interested in that), testing the contract, and deploying it with . Figment Datahub Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust. Foundry is made up of three components: Ethereum testing framework (like Truffle, Hardhat, and Dapptools). Forge: Swiss army knife for interacting with EVM smart contracts, sending transactions, and getting chain data. Cast: local Ethereum node, akin to Ganache, Hardhat Network Anvil: Today’s focus is going to be on But I will be posting in-depth articles on Caste and Anvil in the upcoming weeks. Forge. Why Foundry: There are many smart contract development tools like Truffle, Hardhat, and Brownie. But one of my primary reasons for looking into Dapp Tools in  the first place was native Solidity tests. Writing smart contracts is not hard when switching between frameworks like Hardhat and Brownie. And they are incredible tools with plugins, but one needs to be well versed in JavaScript/TypeScript and Python to perform testing. Foundry allows us to write our tests natively in Solidity. This saves a lot of time onboarding new developers and makes the process smoother. In my experience of helping people navigate their way into smart contracts development, I have learned that the best and most efficient way for junior developers to engage with DAO/community-maintained projects is by writing tests and learning about the code-base itself. I remember once mentioned that they used the same approach while developing Alchemix Finance on . Scupy Trooples Bankless In addition to that, built-in fuzzing, cheat codes, Cast, and Anvil make it a solid suite for testing smart contracts. There will be more detailed articles on those components coming soon. [Easy to integrate static analyzer] Let’s dive in and build an NFT project now. Installation: If you are on Mac or Linux, all you need to do is run two commands: curl -L https://foundry.paradigm.xyz | bash foundryup Make sure to close the terminal before running . foundryup And Voila! You are all done. For Windows, you need to have Rust installed and then : cargo install --git https://github.com/foundry-rs/foundry --locked Project Setup: For this article, we will be creating a simple NFT project called Figbots. Start by creating a directory called “Figbots.” And  run once you are inside the directory. This command will create a foundry project for you with initialized. forge init git Let’s take a quick look at the folder structure. You have three primary folders, namely src, lib, and test. Very much self-explanatory here, you write your contracts in , tests in , and contains all the libraries you installed, e.g., OpenZeppelin. In addition to that, you get which contains all the configurations just like and if you have used those frameworks. Another sweet thing is .github, where you can write your Github Actions. I find it really helpful for tests when working in a team. src test lib foundry.toml hardhat.config.js brownie-config.yaml Let’s start building! We will create a simple NFT called Figbot with a limited supply, cost (for minting), and withdrawal. With this approach, we can cover edges for different tests. First of all, rename and to and respectively. Now, we can not write smart contracts without Openzeppelin, can we? Contract.sol test/Contract.t.sol Figbot.sol Figbot.t.sol Installing libraries with Foundry is slightly different than Hardhat and Brownie. We don’t have npm or pip packages. We install libraries directly from the Source (GitHub repo) in Foundry. forge install Openzeppelin/openzeppelin-contracts Now we can import the ERC721URIStorage.sol extension to create our NFT. To check that everything is alright, we can run the command , and it will compile our project. The compiler will yell at you if there is something wrong. Otherwise, you will get a successful compile. forge build Managing dependencies Just like any other package manager, Forge allows you to use , and to manage your dependencies. forge install <lib>, forge remove <lib> forge update <lib> Let’s Complete The NFT Contract: We will be using three contracts from the Openzeppelin. Counters, ERC721URIStorage, and Ownable. Time to upload our to IPFS using . We use the Ownable contract to set deploying address and have access to modifier to allow only the owner to withdraw funds. to help us with token id(s) and to keep the NFT contract simple. asset Pinata owner onlyOwner Counters ERC721URIStorage Setting state variable: to 100 MAX_SUPPLY to 0.69 ether COST to CID, we receive from Pinata TOKEN_URI Using Counter for token id: using Counters for Counters.Counter; Counters.Counter private tokenIds; ERC721 constructor: constructor() ERC721(“Figbot”, “FBT”) {} Mint function: Check if is greater than msg.value COST Check if is greater or equal to tokenIds.current() MAX_SUPPLY Perform and _safeMint _setTokenURI Withdraw function: function withdrawFunds() external onlyOwner {         uint256 balance = address(this).balance;         require(balance > 0, "No ether left to withdraw");         (bool success, ) = (msg.sender).call{value: balance}("");         require(success, "Withdrawal Failed");         emit Withdraw(msg.sender, balance);     } TotalSupply function: function totalSupply() public view returns (uint256) {                                         return _tokenIds.current();        } Testing The Contract: As we all know, testing our smart contracts is really important. In this section, we will be writing some tests to get a solid understanding of and get used to writing tests in native solidity. We will be three (I love them!) to manage account states to fit our test scenario. forge test Foundry cheat codes We will be testing for the following scenarios: Max Supply Successful mint Failed mint due to insufficient balance Withdraw (by owner) Cheatcodes As we can have complex logic in our smart contracts. And they are expected to behave differently depending on the state, the account used to invoke, time, etc. To deal with such scenarios, we can use cheatcodes to manage the state of the blockchain. We can use these cheatcodes using instance, which is a part of  Foundry’s library. vm Test We will be using three cheatcodes in our tests : : Sets for all subsequent calls until is called. startPrank msg.sender stopPrank : stopPrank Stops an active prank started by , resetting and to the values before was called. startPrank msg.sender tx.origin startPrank : Sets the balance of an address provided address to the given balance. deal Setup Foundry comes with a built-in testing library. We start by importing this test library, our contract (the one we want to test), defining the test, setting variables, and function. setUp pragma solidity ^0.8.13;

import"forge-std/Test.sol";
import "../src/Figbot.sol";

contract FigbotTest is Test {

  Figbot figbot;
  address owner = address(0x1223);
  address alice = address(0x1889);
  address bob = address(0x1778);
  
  function setUp() public {
      vm.startPrank(owner);
      figbot = new Figbot();
      vm.stopPrank(); 
  }
} For state variables, we create a variable of type . This is also the place where I like to define user accounts. In Foundry, you can describe an address by using the syntax . you can use any four alphanumeric characters for this. I have created the accounts named owner, Alice, and bob, respectively. figbot Figbot address(0x1243) Now our function. This is a requirement for writing tests in Foundry. This is where we do all the deployments and things of that nature. I used the cheatcode to switch the user to the “owner.” By default, Foundry uses a specific address to deploy test contracts. But that makes it harder to test functions with special privileges like . Hence, we switch to the “owner” account for this deployment. setUp startPrank withdrawFunds Test MaxSupply: Starting with a simple assertion test to learn Foundry convention. By convention, all the test functions must have the prefix . And we use to test if two values are equal. test assertEq We call our function and test if the result value is 100, as we described in our contract. And we use to run our tests. MaxSupply forge test And Voila!!! we have a passed test. Test Mint: Now that we have written a simple test, let’s write one with cheatcodes. The primary function of our contract. Switch user account to Alice. Set Alice’s balance to 1 ether Call the mint function Check if Alice is 1 balanceOf TestFail Mint: We have another testing function used for tests that we expect to fail. The prefix used for such a test is . We will test if the function reverts if the caller has insufficient funds. testFail mint Switch user account to Bob Set Bob’s balance to 0.5 ether (our NFT is 0.69 ether) Call the mint function (it will be reverted due to not having enough funds) Check if Bob is 1 balanceOf Because mint didn’t go through, the balance of Bob is not going to be 1. Hence, it will fail, which is exactly what we are used for. So when you run , it will pass. testFail forge test Test Withdraw: Here we will test a function that only the “owner” can successfully perform. For this test, we will : Switch user to Bob Give Bob’s account the balance of 1 ether Mint a Figbot from Bob’s account ( this will give the contract a balance of 0.69 ether ) Switch the user to the owner account Perform function ( if successful, it should make the owner’s balance 0.69 ether) withdrawFunds To verify, we assert if the owner’s balance is 0.69 ether Deployment: Now that we have tested our contract, it is time to deploy it. We need private keys to a wallet (with some Rinkeby test ETH) and an RPC URL. For our RPC URL, we will use . Figment DataHu Figment DataHub provides us with infrastructure to develop on Web 3. It supports multiple chains like Ethereum, Celo, Solana, Terra, etc. Setting up Figment DataHub: Create an account on . Figment DataHub Click on “Create New App.” Fill in the app name. Choose “Staging” for the environment. Select “Ethereum” from the provided options. You can get your RPC URL for Rinkeby from under the “Protocols” tab. Open your terminal to enter both of these things as environment variables. export FIG_RINKEBY_URL=<Your RPC endpoint>
export PVT_KEY=<Your wallets private key> Once we have the environment variables, we are all set to deploy forge create Figbot --rpc-url=$FIG_RINKEBY_URL --private-key=$PVT_KEY Verification: We are almost done here. So far, we have written, tested, and deployed a smart contract with Foundry and Figment DataHub. But we are not entirely done just yet. We are now going to verify our contract. We will need to set up our API key for that. Etherscan export ETHERSCAN_API=<Your Etherscan API Key> And now we can verify our smart contract. forge verify-contract --chain-id <Chain-Id> --num-of-optimizations 200  --compiler-version <Compiler Version> src/<Contract File>:<Contract>  $ETHERSCAN_API Congratulations! Now you can write, test, and deploy smart contracts using Foundry. I hope you enjoyed and learned from this article. I indeed enjoyed writing this. Feel free to let me know your thoughts about it.

The goal of this article is to demonstrate how to create an ERC20 token in as little time as possible. Let’s start with the basics: What is an ERC20 token? In recent years, the ERC20 token specification has become the defacto standard for Ethereum tokens. In other words, most Ethereum contracts out there today are ERC20-compliant. This article will detail how you can create your own Ethereum token, but before we get started, let’s take a closer look at the ERC20 standard. What makes ERC20 tokens so attractive and successful? There are several factors in play: ERC20 tokens are simple and easy to deploy, as you will see in this tutorial. The ERC20 standard solves a significant problem, as blockchain-based marketplaces and crypto-wallets need a single, standardized set of commands to communicate with the range of tokens they manage. This includes interaction rules between different tokens, as well as token purchase rules. It was the first popular specification to offer Ethereum token standardization. It was not by any means , but thanks to its popularity, it quickly became the industry standard. the first Just like other Ethereum tokens, ERC20 tokens are implemented as smart contracts and executed on the Ethereum Virtual Machine (EVM) in a decentralized manner. Solidity: the Smart Contract Programming Language Ethereum smart contracts are written in Solidity. While there are alternative languages, hardly anyone uses them for this purpose. Solidity is similar to JavaScript, so if you have some knowledge of JavaScript, or even Java and other C-like languages, you should have no trouble figuring out that a piece of code in Solidity does, even before you actually master Solidity enough to use it. This is where the fun starts, as you should be able to start creating a simple ERC20 contract in no time. This is a straightforward task, simple enough that this article will demonstrate how you can write and deploy an ERC20 token in under an hour. The token we will be creating in this demonstration will be a bare-bones ERC20 implementation, without too many bells and whistles. However, I have seen many similarly simple tokens in the real world, and they tend to do quite well. Overview of ERC20 Token Standard What is ERC20? Put simply, the ERC20 standard defines a set of functions to be implemented by all ERC20 tokens so as to allow integration with other contracts, wallets, or marketplaces. This set of functions is rather short and basic. function totalSupply() public view returns (uint256); function balanceOf(address tokenOwner) public view returns (uint); function allowance(address tokenOwner, address spender) public view returns (uint); function transfer(address to, uint tokens) public returns (bool); function approve(address spender, uint tokens) public returns (bool); function transferFrom(address from, address to, uint tokens) public returns (bool); ERC20 functions allow an external user, say a crypto-wallet app, to find out a user’s balance and transfer funds from one user to another with proper authorization. The smart contract defines two specifically defined events: event Approval(address indexed tokenOwner, address indexed spender, uint tokens); event Transfer(address indexed from, address indexed to, uint tokens); These events will be invoked or when a user is granted rights to withdraw tokens from an account, and after the tokens are actually transferred. emitted In addition to standard ERC20 functions, many ERC20 tokens also feature additional fields and some have become a de-facto part of the ERC20 standard, if not in writing then in practice. Here are a few examples of such fields. string public constant name; string public constant symbol; uint8 public constant decimals; Here are a few points regarding ERC20 and Solidity nomenclature: A public function can be accessed outside of the contract itself view basically means constant, i.e. the contract’s internal state will not be changed by the function An event is Solidity’s way of allowing clients e.g. your application frontend to be notified on specific occurrences within the contract Most Solidity language constructs should be clear if you already possess essential Java/JavaScript skills. Writing an ERC20 Token in Solidity Now that we’ve outlined the basics and explained what it takes to create an ERC20 token, it is time to start writing some logic. First, we need to define two mapping objects. This is the Solidity notion for an associative or key/value array: mapping(address => uint256) balances; mapping(address => mapping (address => uint256)) allowed; The expression mapping(address => uint256) defines an associative array whose keys are of type address— a number used to denote account addresses, and whose values are of type uint256 — a 256-bit integer typically used to store token balances. The first mapping object, balances, will hold the token balance of each owner account. The second mapping object, allowed, will include all of the accounts approved to withdraw from a given account together with the withdrawal sum allowed for each. As you can see, the value field of the allowed mapping is by itself a mapping plotting account address to its approved withdrawal sum. These mappings together with all other contract fields will be stored in the blockchain and will be resulting in changes being propagated to all network user nodes. mined Blockchain storage is expensive and users of your contract will need to pay for, one way or another. Therefore you should always try to minimize storage size and writes into the blockchain. Now that we have the required data structures in place, we can start to actually write the ERC20 logic into the appropriate functions. Setting the Number of ICO Tokens How do we set the number of ICO tokens? Well, there are a number of ways of setting the maximal number of ICO tokens and this matter might be worth a lengthy discussion by itself. For the needs of our ECR20 tutorial, we shall use the simplest approach: Set the total amount of tokens at contract creation time and initially assign all of them to the “contract owner” i.e. the account that deployed the smart contract: uint256 totalSupply_; constructor(uint256 total) public { totalSupply_ = total; balances[msg.sender] = _totalSupply; } A constructor is a special function automatically called by Ethereum right after the contract is deployed. It is typically used to initialize the token’s state using parameters passed by the contract’s deploying account. msg is a global variable declared and populated by Ethereum itself. It contains important data for performing the contract. The field we are using here: msg.sender contains the Ethereum account executing the current contract function. Only the deploying account can enter a contract’s constructor. When the contract is started up, this function allocates available tokens to the ‘contract owner’ account. Get Total Token Supply function totalSupply() public view returns (uint256) { return totalSupply_; } This function will return the number of all tokens allocated by this contract regardless of owner. Get Token Balance of Owner function balanceOf(address tokenOwner) public view returns (uint) { return balances[tokenOwner]; } balanceOf will return the current token balance of an account, identified by its owner’s address. Transfer Tokens to Another Account function transfer(address receiver, uint numTokens) public returns (bool) { require(numTokens <= balances[msg.sender]); balances[msg.sender] = balances[msg.sender] — numTokens; balances[receiver] = balances[receiver] + numTokens; emit Transfer(msg.sender, receiver, numTokens); return true; } As its name suggests, the transfer function is used to move numTokens amount of tokens from the owner’s balance to that of another user, or receiver. The transferring owner is msg.sender i.e. the one executing the function, which implies that only the owner of the tokens can transfer them to others. Solidity’s way of asserting a predicate is require. In this case that the transferring account has a sufficient balance to execute the transfer. If a require statement fails, the transaction is immediately rolled back with no changes written into the blockchain. Right before exiting, the function fires ERC20 event Transfer allowing registered listeners to react to its completion. Approve Delegate to Withdraw Tokens This function is most often used in a token marketplace scenario. function approve(address delegate, uint numTokens) public returns (bool) { allowed[msg.sender][delegate] = numTokens; emit Approval(msg.sender, delegate, numTokens); return true; } What approve does is to allow an owner i.e. msg.sender to approve a delegate account — possibly the marketplace itself — to withdraw tokens from his account and to transfer them to other accounts. As you can see, this function is used for scenarios where owners are offering tokens on a marketplace. It allows the marketplace to finalize the transaction without waiting for prior approval. At the end of its execution, this function fires an Approval event. Get Number of Tokens Approved for Withdrawal function allowance(address owner, address delegate) public view returns (uint) { return allowed[owner][delegate]; } This function returns the current approved number of tokens by an owner to a specific delegate, as set in the approve function. Transfer Tokens by Delegate The transferFrom function is the peer of the approve function, which we discussed previously. It allows a delegate approved for withdrawal to transfer owner funds to a third-party account. function transferFrom(address owner, address buyer, uint numTokens) public returns (bool) { require(numTokens <= balances[owner]); require(numTokens <= allowed[owner][msg.sender]); balances[owner] = balances[owner] — numTokens; allowed[owner][msg.sender] = allowed[from][msg.sender] — numTokens; balances[buyer] = balances[buyer] + numTokens; Transfer(owner, buyer, numTokens); return true; } The two require statements at function start are to verify that the transaction is legitimate, i.e. that the owner has enough tokens to transfer and that the delegate has approval for (at least) numTokens to withdraw. In addition to transferring the numTokens amount from owner to buyer, this function also subtracts numTokens from the delegate’s allowance. This basically allows a delegate with a given allowance to break it into several separate withdrawals, which is typical marketplace behavior. We could stop here and have a valid ERC20 implementation. However, we want to go a step further, as we want an industrial strength token. This requires us to make our code a bit more secure, though we will still be able to keep the token relatively simple, if not basic. SafeMath Solidity Library is a Solidity library aimed at dealing with one way hackers have been known to break contracts: integer overflow attack. In such an attack, the hacker forces the contract to use incorrect numeric values by passing parameters that will take the relevant integers their maximal values. SafeMath past protects against this by testing for overflow before performing the arithmetic action, thus removing the danger of overflow attack. The library is so small that the impact on contract size is minimal, incurring no performance and little storage cost penalties. SafeMath Let’s add to our code: SafeMath library SafeMath { // Only relevant functions function sub(uint256 a, uint256 b) internal pure returns (uint256) { assert(b <= a); return a — b; } function add(uint256 a, uint256 b) internal pure returns (uint256) { uint256 c = a + b; assert(c >= a); return c; } } uses assert statements to verify the correctness of the passed parameters. Should assert fail, the function execution will be immediately stopped and all blockchain changes shall be rolled back. SafeMath Next, let us add the following statement introducing the library to the Solidity compiler: using SafeMath for uint256; Then, we replace the naive arithmetics we used at the beginning with SafeMath functions: balances[msg.sender] = balances[msg.sender].sub(numTokens); balances[receiver] = balances[receiver].add(numTokens); balances[buyer] = balances[buyer].add(numTokens); balances[owner] = balances[owner].sub(numTokens); Packing it all Together In Solidity, a smart contract’s functions and events are wrapped into an entity called a which you can silently translate to a “blockchain class.” Below is the ERC20-compatible contract we created, including a Gist of our code. The name and symbol fields can be changed at will. Most tokens keep the decimal value at 18, so we will do the same. contract Ethereum Contract Deployment The time has come to . Following deployment, our contract will be transferred to all nodes participating in the network. Any and all changes made to the contract will be propagated to all participating nodes. deploy our contract to the blockchain Ethereum developers usually employ deployment tools such as . Even Truffle is overkill for the limited needs of this article, and a simple online tool called will suffice. Truffle Remix To use it, you will need to install the on your browser and a Rinkeby (Ethereum test network) account with at least some Rinkeby Ether in it. These are relatively simple steps, so we won’t go into detail. MetaMask plugin In case you don’t have either, head over to and for download links and to get clear installation and usage directions. MetaMask Rinkeby Now that we have all the building blocks in place, we will head over to and paste the code above, including the pragma line and the SafeMath library, into the online editor. Remix Then, we will hop over to the second tab to the right called “ ” and click “ .” A MetaMask popup will appear asking us to confirm the transaction. Of course, we’ll approve it. Run Deploy Green box: Make sure you’re on Rinkeby Blue box: Set your total token supply Red box: Deploy! : Gist https://gist.github.com/giladHaimov/8e81dbde10c9aeff69a1d683ed6870be#file-basicerc20-sol You have just deployed your first ERC20 token, like a true . As promised, the token is simple and lightweight, yet fully functional, ERC20 standard compliant, and secured with MathSafe. It is ready to be purchased, paid with, and transferred throughout the Blockchain. Congrats! Ethereum professional Is that all there is to smart contracts? No, not even close, as our brief demonstration barely scratches the surface and deals solely with one aspect of smart contract development. Smart contracts can be much more complex depending on your business logic, your modeling of the user interaction, whether or not you allow token minting and burning, lifecycle changes you introduce into the contract, the need for admin-level capabilities which usually comes with an admin-authorized set of functions, and so on. You get the picture. Still, if you can replicate what we did here, that is a solid foundation to expand your knowledge and move on to more complex contracts when necessary. A smart contract is a piece of code executed on the Ethereum Virtual Machine. An Ethereum smart contract is immutable and can send or receive ether and data. Put simply, ERC20 tokens are contracts that implement the ERC20 standard. Operations handled by these contracts include getting the total supply and balance of tokens, and the methods used to transfer them. Ethereum development is currently conducted in Solidity, a contract-oriented programming language inspired by JavaScript, Python, and C++. ERC stands for Ethereum Request for Comment. The number 20 is assigned to this request, hence the suffix. Originally published at www.toptal.com .
