WalletConnect

walletconnect

We will create from scratch ERC-721 smartcontract, deploy it to Ethereum Goerli network using Hardhat + Solidity. For minting we will use NextJs + WalletConnect + Web3Modal Before we start, I would like to mention, that you can use any network you want. With the help of this article, you can deploy to Mainnet also. Smartcontract repo (erc721): https://github.com/gapon2401/erc721 Mint page repo (erc721-mint): https://github.com/gapon2401/erc721-mint Smartcontract: Etherscan Goerli link We need to go through the following steps to reach our goal: Creating NFT (ERC-721) smartcontract Configure hardhat.config.ts and .env Create deploy function Create tests Gas price for deployment and minting the smartcontract Creating images and metadata for NFT Deploy and verify smartcontract Create demo website for minting (optional) Deep dive and customize Step 1. Creating NFT (ERC-721) smartcontract Create new project and install — Ethereum development environment. Let’s call this project . https://hardhat.org erc721 In command line run npx hardhat Select . Create a Typescript project In order to continue you will be asked to install some dependencies. The text may vary on the hardhat version. I will run the following, because I will use : yarn yarn add -D hardhat@^2.10.2 @nomicfoundation/hardhat-toolbox@^1.0.1 We will use template for ERC-721 smartcontract, where all necessary functions have been implemented. You can take a look on it: https://www.openzeppelin.com/ https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol Install openzeppelin packages and dotenv: yarn add -D @openzeppelin/contracts dotenv Remove everything from the folder and create a file with the contents: contracts ERC721Contract.sol https://gist.github.com/gapon2401/d6bf2f0eef9b7e6721b98028f890004e If you have any difficulties with the code above, feel free to read more about the . Here is the summary: Solidity — on deployment we will set the base URI for all tokens, name and a symbol to the token collection. constructor — is our function, which will create new NFT’s for us. Only owner of the contract can call it. mintByOwner — public mint. mint — owner of the contract can change the base URI for tokens setBaseURI —owner can call this function to transfer money from the contract to it’s own wallet address withdraw All other necessary functions are inhereted in this contract from openzeppelin. The price of the tokens will be 0.1 ETH: uint256 public constant PRICE = 100000000000000000; Configure hardhat.config.ts and .env Step 2. Install the following dependencies in order to escape the errors in developing 😲 yarn add -D ethers @nomiclabs/hardhat-etherscan @typechain/hardhat hardhat-gas-reporter solidity-coverage @types/chai @types/mocha typescript ts-node @nomicfoundation/hardhat-chai-matchers chai @nomicfoundation/hardhat-network-helpers typechain @nomiclabs/hardhat-waffle @typechain/ethers-v5 @nomiclabs/hardhat-ethers Now configure your : hardhat.config.ts https://gist.github.com/gapon2401/4bd368815c075954f7cac6b43e1cd687 What do we have here: — we specified the settings and enabled optimization solidity — networks, that we are going to use networks — will show us gas units, that we need to spend for deployment or calling the functions gasReporter — plugin for integration with Etherscan’s contract verification service etherscan The next step is to create file in project root. You have to create 5 variables: .env — the private key of the wallet, that wil be the owner of the contract PRIVATE_KEY -etherscan key. Register on and on the page create and copy your key: ETHERSCAN_API_KEY https://etherscan.io https://etherscan.io/myapikey — Are we going to use gas reporter or not. We will use it REPORT_GAS=1 and — use or for getting the urls. GOERLI_URL MAINNET_URL https://infura.io/ https://www.alchemy.com/ For instance, infura URL for : MAINNET_URL Infura URL for : GOERLI_URL Now compile the code with the command: npx hardhat compile After that command some new folders will appear: , , . artifacts cache typechain-types Step 3. Create deploy function It’s time to write deploy function, we will use tasks for it. Remove folder , we don’t need it. scripts Create the folder and the file inside it: tasks deploy.ts https://gist.github.com/gapon2401/6dbb24a1308479d934897abf743c32e1 In this task we get smartcontract and deploy it. After the deployment in console we will see the address of the contract. We will come back to that function later. Create tests Step 4. We will write the tests for every exteral/public function. Clear the folder and create inside it with the contents: test index.ts https://gist.github.com/gapon2401/47162e377dde919f06108905ecdb847f Run . npx hardhat test You should get similar to that: All tests passed successfully! Gas price for deployment and minting the smartcontract Step 5. For determine the price of deployment and minting functions we have used module . It was enabled by default in , that’s why after all tests were passed, we got the table: hardhat-gas-reporter hardhat.config.ts In the table we can see the gas consumption for methods and deployment. This is the units of gas we need to deploy the contract. How much it will cost in ETH? Use the formula: (gas units) * (gas price per unit) = gas fee in gwei In this formula we don’t know the amount of . gas price per unit You can use or any other website to find this information. At the moment of writing this article, gas price is 17. https://ethgasstation.info/ The value can change greatly depending on the time of day. It may be 2 or 10 or 50 🙃. Be careful. So, the average cost will be: Deployment = 1 697 092 * 17 = 28 850 564 gwei = 0,028850564 ETH
mint = 88 753 * 17 = 1 508 801 gwei = 0,001508801 ETH
mintByOwner = 91 060 * 17 = 1 548 020 gwei = 0,001548020 ETH
setBaseURI = 32 153 * 17 = 546 601 gwei = 0,000546601 ETH
withdraw = 30 421 * 17 = 517 157 gwei = 0,000517157 ETH Now the ETH/USD price is $1 592, it means that deployment to mainnet will cost about $46 and calling a function will cost about $2.4. mint Creating images and metadata for NFT Step 6. Images and metadata for NFTs can be stored on your server or in . IPFS We will cover the first case. Assume, that you have a domain https://my-domain.com All NFT images will store here: https://my-domain.com/collection/assets/ All metadata here: https://my-domain.com/collection/metadata/ So, the base URI for our smartcontract will be https://my-domain.com/collection/metadata/ In our smartcontract by default all token URI’s will be counted from 0. Therefore, files for metadata should be like this: 0.json
1.json
....
1234.json If you use function, then you can change the name of the file for specific NFT, and it can be like this: mintByOwner custom.json Upload NFT images on your server. They should be available by links: https://my-domain.com/collection/assets/0.png
https://my-domain.com/collection/assets/1.png
https://my-domain.com/collection/assets/2.png Now create metadata for NFT’s. Here is an example of one file : 0.json {
    "name": "Test NFT #0",
    "image": "https://my-domain.com/collection/assets/0.png"
} Pay attention, that in we have defined the link to the image, which has been upoaded to the server. image about opensea metadata and available values in it. Read more Upload your metadata files, so they should be available by links: https://my-domain.com/collection/metadata/0.json
https://my-domain.com/collection/metadata/1.json
https://my-domain.com/collection/metadata/2.json Step 7. Deploy and verify smartcontract Everything is ready for deployment. Take a look on our , we’ve specified as tasks/deploy.ts baseUri https://my-domain.com/collection/metadata/ This is because all our metadata is available by this address. Here you can change the and the of the collection. name symbol In command line run: npx hardhat deploy --network goerli This command will deploy smartcontract to Goerli network. If you want to deploy to mainnet, you can run: npx hardhat deploy --network mainnet All these networks were described on file. hardhat.config.ts After the deployment you will get the following in your console: My smartcontract address is: 0xc191B6505B16EBe5D776fb30EFbfe41A9252023a From now, it is available on etherscan testnet: https://goerli.etherscan.io/address/0xc191B6505B16EBe5D776fb30EFbfe41A9252023a We need to verify our smartcontract, so everyone can check the code. Wait about 5 minutes and try to verify it. If you get an error while verifying, don’t worry, just try to wait more time. In Mainnet I was waiting for 10–15 minutes. In general verify function looks like this: npx hardhat verify --network <YOUR_NETWORK> <DEPLOYED_CONTRACT_ADDRESS> <arg1> <arg2> <argn> Let’s try to determine, what to specify in our verify function: <YOUR_NETWORK> - goerli <DEPLOYED_CONTRACT_ADDRESS> will be my contract address 0xc191B6505B16EBe5D776fb30EFbfe41A9252023a <arg1> — this is our base URI. You will find it in tasks/deploy.ts "https://my-domain.com/collection/metadata/" <arg2> — name of the token collection, that was specified in deployment: "My ERC721 name" <arg3> — symbol of the token collection, that was specified in deployment: "MyERC721Symbol" Arguments should be the same, that were in !!! tasks/deploy.ts So, in command line I will run: npx hardhat verify --network goerli 0xc191B6505B16EBe5D776fb30EFbfe41A9252023a "https://my-domain.com/collection/metadata/" "My ERC721 name" "MyERC721Symbol" The result should be the next: On you can check the code of deployed smartcontract. this page 🥳We have finished with the smartcontract. Here is the , where you can find all the code. repo Step 8. Create demo website for minting This will be our second project . erc721-mint For demo website I will use . NextJS To speed up the development clone my repository: https://github.com/gapon2401/erc721-mint Install all dependencies: yarn install Open file and fill in the variables: .env — address of your smartcontract from the paragraph Deploy and verify smartcontract. NEXT_PUBLIC_SMARTCONTRACT_ADDRESS — the network, where your smartcontract was deployed. We need this to switch the network. Specify , because we have deployed our smartcontact there. NEXT_PUBLIC_SMARTCONTRACT_NETWORK goerli — network endpoint. You can use to get the url. NEXT_PUBLIC_SMARTCONTRACT_INFURA_URL https://infura.io Go to your dashboard, select your project and copy : Api Key In our first smartcontract project open the file: erc721 artifacts/contracts/ERC721Contract.sol/ERC721Contract.json Copy : abi In current project open the file: erc721-mint src/components/smartcontract.ts Replace the value. abi Everything is done! 🎉 You can run the project and try to use it! yarn dev In the next section I will cover the main components. Step 9 (optional). Deep dive and customize Take a look on main components: src/components/smartcontract.ts Contains information about the smartcontract. It's better to dynamically load this file from the server, because we want our web page loads as soon as possible. In this demo mint form appears after the page loads.
2. This component communicates with blockchain. There are some functions and variables stored in React Context: src/components/Web3Provider.tsx - has user connected the wallet or not connected - the state of reconnecting isConnecting - function for connecting to network connect() – function for reconnecting. Cached provider will be used, that was selected by user at the last time reconnect() – function for disconnecting network – selected by user disconnect() : goerli, mainnet etc network – provider for communicating with the wallet: metamask, ledger, tokenary, etc provider - the owner of the wallet signer – ID of the selected network chainId – your wallet address accountId - error message for web3Modal error This component displays form for minting.
Function is called after the user clicks on the mint button.
Now look at the code: src/components/MintForm.tsx mint() const transactionResponse = await Contract.mint({ 
  value: ethers.utils.parseEther('0.1'), 
}) We are calling function from the smartcontract and send 0.1 ETH to it, because this function requires exactly that value. mint What if we want to call mintByOwner ? We can do it like this: const transactionResponse = await Contract.mintByOwner( '0x01234566', 'token_uri' ) But pay attention, that this function can be called only by the owner of the contract. Why? We have used modifier in smartcontract: onlyOwner function mintByOwner(address to, string calldata tokenUri) external onlyOwner A few more words about that function. - this is the address, for which you want to mint token. Make sure to write full address. 0x01234566 - this is custom token URI. In our deployed smartcontract the full address to token metadata looks like: token_uri ${baseUri + token_uri}.json Remember, we have specified : baseUri https://my-domain.com/collection/metadata/ So, the full address to metadata with token URI equals will be: token_url https://my-domain.com/collection/metadata/token_url.json Also, we don't need to pay for this transaction, except gas price. Function . prepareNetwork() On first connection this function can propose to change the network. In this function are used only and networks. You can change it, if you need, here: goerli mainnet chainId: smartContract.network === 'goerli' ? '0x5' : '0x1', Function . getBalanceOf This function checks is it enough money on the wallet to make a transaction. In the file you may find commented code in two places: /* reconnect ,*/ and /* Reconnect to the wallet */ 
// useEffect(() => {
 //   ;(async () => {
 //     await reconnect()
 //   })()
 // }, [reconnect]) Uncomment it to make reconnections every time the page reloads. Thank you for reading! ❤

**LONDON, United Kingdom, October 22nd, 2024/Chainwire/--**Peanut launches the first self-custodial offramp, allowing users to directly cash out any token on 20+ EVM chains to their bank accounts—without relying on centralized exchanges. This beta feature is being rolled out in the EU and US first. This new beta feature creates an important bridge between crypto and fiat. Users can cash out funds from any token on 20+ EVM chains directly in US Dollars or Euros to their bank account. This works by creating a bridge between the blockchains and fiat payments networks like IBAN, BIC, or SWIFT. Peanut’s key feature is texting funds using QR codes or messengers such as WhatsApp, Telegram, email etc. With the self-custodial offramp, recipients can now transfer their funds directly to their bank account without the need to have a wallet themselves. This breakthrough in crypto accessibility makes transferring money across platforms frictionless and user-friendly. In addition to texting funds without worrying whether the recipient uses crypto or fiat, users of self-custodial wallets can now directly offramp into their bank account without using a CEX. “Texting money is now possible,” said Hugo Montenegro, co-founder of Peanut and a Harvard graduate. “This is a major step toward simplifying crypto for everyday use, meaning you can send stablecoins through channels like WhatsApp, Telegram, Email etc.” For the beta launch of this new feature, Peanut Protocol will give each user the first 5 transactions for free. Afterwards, a small fee will apply. The minimum cashout amount is $10. About Peanut Peanut is at the forefront of transforming crypto payments with its innovative fully decentralized self-custodial protocol - Peanut Protocol. It enables seamless, cross-chain and offramping transactions. The platform allows users to easily send, receive, cross-chain swap and offramp funds to fiat currencies, making crypto more accessible than ever. Peanut’s unique secret-protected vault smart contracts provide top-tier security, ensuring that funds are only released when a private link is shared by the sender. “Anyone can now send funds seamlessly,” said Derek, CTO of Reown. With support for over 20 blockchain networks and plans to expand to Bitcoin and Solana, Peanut Protocol is committed to simplifying the crypto experience for everyone. As a non-custodial, permissionless solution, Peanut empowers users with full control of their digital assets.

As the cryptocurrency sector becomes increasingly popular, the number of global users has exceeded 562 million in 2024 (and is projected to reach 1 billion users by 2030). With this growth, comes the need for secure crypto storage. A crypto wallet allows you to buy, sell, send, receive, and store cryptocurrency. Ledger has been a major player in the crypto storage sector since 2014 when it launched its first hardware wallet. https://giphy.com/gifs/tteaCAnuXs4DHdpBPE?embedable=true The Ledger Stax, its latest release, is currently available for pre-order, and that’s why I wrote this review. To share with you a glimpse of the device before it’s even available in stores. But before that, let's talk wallets for a sec—there are so many out there, each with distinct features and quirks. Up until now, I've mostly been using Trezor and the previous models from Ledger. But what's this new device, you ask? Honestly, I had no clue what to expect. The flashy pictures Ledger threw up online caught my eye, and before I knew it, I had ordered a few of them. Call it impulse buying or call it faith in Ledger's knack for cool gadgets. By the end of this review, you will make an informed choice whether the new Ledger Stax is a good buy or not. Features of Ledger Stax Ledger Stax stands out with its sleek design and added features, making it a solid upgrade from previous models, the Ledger Nano X and Nano S. https://giphy.com/gifs/xLrFCzPUlG6mnSTVUR?embedable=true The wallet comes with a larger display, unlike the Ledger Nano S and Nano X, which had relatively smaller screens. The screen sets itself apart with its size and intuitive design, making it easy to navigate, sign transactions, and use basic features like sending, receiving, buying, and selling crypto. I can't forget to mention the real-time portfolio overview, which lets you keep a close eye on your portfolio. https://giphy.com/gifs/ETqUUbur3oFyTsSIkP?embedable=true I’ve also got to highlight the quality build using long-lasting quality materials, ensuring a long service life. I am not forgetting the modern USB port, which makes connecting to other devices a breeze. Ledger Stax - Technical Overview The Ledger Stax combines aluminum and plastic with stackability and is available in Graphite color. It features a 3.7-inch E Ink® curved touchscreen display with 16 scales of gray. It's equipped with a Secure Element Chip ST33K1M5, certified with CC EAL6+ for high security. The Ledger Stax supports over 500 cryptocurrencies and tokens, including Ethereum and Polygon NFTs, through the Ledger Live app. It is compatible with 64-bit desktop computers (Windows 10/11, macOS, Ubuntu) and smartphones (iOS 14+, Android 10+), but not Chromebooks or mining. More technical specifications are available here. The package includes 1 Ledger Stax device, 1 USB-C to USB-C cable, 1 Recovery Sheet, 1 Ledger Stax Magnet Shell in Midnight Black, and a guide for the Ledger Stax. Ledger Stax Pros and Cons Pros Super design
Intuitive touchscreen (with smooth navigation)
Easy to use
Crypto and NFT functionality
Durable, long-lasting material Cons Not the most secure packaging.
Except for the new physical design, it duplicates most of the functionality from previous models. Buying NFTs with Ledger Stax - My User Experience Today, I'm diving into my Ledger Stax wallet (which already holds one Ethereum) to buy an NFT. For this, I'll be using my favorite NFT PFP (Picture-for-Profile) maker, 8biticon. It was churning out stylish 8-bit PFPs long before the hype and the CryptoPunks, making it a true original. You can check out my avatar here - 8biticon.com/constructor?token=192440955321416. This is a really cool constructor: it’s super easy to use, with a sleek, user-friendly interface. . and if you want a unique and awesome PFP on ERC-20 (currently the only supported one), it’s definitely worth trying out. Now, moving on to buying the NFT. I’ve got my 1 Ether ready, and my account set up on 8biticon.com. I've generated this stylish dude for myself, and now I want to buy him using my mobile phone and Ledger Stax, which is connected to it via Bluetooth. I click “Buy now.” Next, I have to choose how I am going to purchase since I'm not talking about browser extensions, but my mobile wallet. Here, it gets a bit tricky. Since I’m not using a browser extension, but a mobile wallet, I need to use WalletConnect. Once selected, choose “Mobile.” The UI here could be smoother - personally, I’d love to see a “Scan QR” button more readily available, as it took me a moment to figure out the process. After selecting the WalletConnect icon in the Ledger app, I press “Connect”, scan the QR code, and confirm the connection. With these steps done, I’m connected to the website, and my ETH wallet address appears. The final step is to confirm the mint payment. Once processed, the site quickly confirms a successful transaction, and my avatar begins the minting process. YAY!!!! All that's left is to wait for it in the wallet itself. And there it is; that all looks well and good. So, that’s my experience with buying NFTs using Ledger Stax. Have fun using Ledger Stax! Conclusion Ledger Stax is an advanced hardware crypto wallet that combines style, convenience, and innovative features for the next generation of crypto HODLers. Despite some drawbacks, such as insufficient packaging protection, this device has all the chances to become a popular go-to hardware wallet among cryptocurrency users. I advise that you go through the setup guide for the Ledger Stax wallet as it may require some level of understanding of cryptocurrencies. The process may appear technical at first but it’s something you can get around easily.  And is meant to achieve maximum protection of your assets. One more thing - your Secret Recovery Sheet is like the keys to your Ledger Stax kingdom, so keep it safe! And hey, don’t do what I did in the picture below. Seriously though, never share it. Stay smart, stay secure! As the cryptocurrency sector becomes increasingly popular, the number of global users has exceeded 562 million in 2024 (and is projected to reach 1 billion users by 2030).

Except for the new physical design, it duplicates most of the functionality from previous models. Buying NFTs with Ledger Stax - My User Experience Today, I'm diving into my Ledger Stax wallet (which already holds one Ethereum) to buy an NFT. For this, I'll be using my favorite NFT PFP (Picture-for-Profile) maker, 8biticon. It was churning out stylish 8-bit PFPs long before the hype and the CryptoPunks, making it a true original. You can check out my avatar here - 8biticon.com/constructor?token=192440955321416 . 8biticon.com/constructor?token=192440955321416 8biticon.com/constructor?token=192440955321416 This is a really cool constructor: it’s super easy to use, with a sleek, user-friendly interface. . and if you want a unique and awesome PFP on ERC-20 (currently the only supported one), it’s definitely worth trying out. Now, moving on to buying the NFT. I’ve got my 1 Ether ready, and my account set up on 8biticon.com. I've generated this stylish dude for myself, and now I want to buy him using my mobile phone and Ledger Stax, which is connected to it via Bluetooth. I click “Buy now.” this stylish dude this stylish dude “Buy now.” Next, I have to choose how I am going to purchase since I'm not talking about browser extensions, but my mobile wallet. Here, it gets a bit tricky. Since I’m not using a browser extension, but a mobile wallet, I need to use WalletConnect . WalletConnect Once selected, choose “Mobile.” The UI here could be smoother - personally, I’d love to see a “Scan QR” button more readily available, as it took me a moment to figure out the process. “Mobile.” “Scan QR” After selecting the WalletConnect icon in the Ledger app, I press “Connect” , scan the QR code, and confirm the connection. WalletConnect “Connect” With these steps done, I’m connected to the website, and my ETH wallet address appears. The final step is to confirm the mint payment. Once processed, the site quickly confirms a successful transaction, and my avatar begins the minting process. YAY!!!! All that's left is to wait for it in the wallet itself. And there it is; that all looks well and good. So, that’s my experience with buying NFTs using Ledger Stax. Have fun using Ledger Stax! Conclusion Ledger Stax is an advanced hardware crypto wallet that combines style, convenience, and innovative features for the next generation of crypto HODLers. Despite some drawbacks, such as insufficient packaging protection, this device has all the chances to become a popular go-to hardware wallet among cryptocurrency users. I advise that you go through the setup guide for the Ledger Stax wallet as it may require some level of understanding of cryptocurrencies. The process may appear technical at first but it’s something you can get around easily.  And is meant to achieve maximum protection of your assets. One more thing - your Secret Recovery Sheet is like the keys to your Ledger Stax kingdom, so keep it safe! And hey, don’t do what I did in the picture below. Seriously though, never share it.

Ledger Stax Review: An Innovative Wallet for Asset Storage

AMSTERDAM, Netherlands, September 18th, 2024/Chainwire/--Token 2049 Attendees Can Collect DOTphin Proof of Presence Digital Avatars and Contribute to Real-World Environmental Impact Sovereign Nature Initiative (SNI) has joined forces with Unique Network and WalletConnect to launch DOTphin, an innovative Polkadot NFT project for attendees of Token 2049 in Singapore. Attendees are invited to visit the Polkadot booth (Booth #P34 and 42, located on level 5 of the Marina Bay Sands Convention Center) and collect their Proof of Presence (PoP) and begin their journey with DOTphin avatars which evolve through user interaction and contribute to real-world marine conservation efforts. By participating in the DOTphin experience, Token 2049 attendees can collect a PoP, unlocking stages in the avatar’s evolution, which is influenced by ecological data from SNI’s marine conservation partner, Aquasearch. This innovative fusion of blockchain and ecological impact empowers users to play a role in preserving marine life while engaging with cutting-edge technology. Catherine Bischoff, CEO of SNI shared, "Our goal at Sovereign Nature Initiative is to rethink the economics of biodiversity conservation and restoration. Through DOTphin, we have pioneered a groundbreaking approach to merge community engagement and the protection of our natural world by connecting digital collectibles with living entities. We add meaning to virtual realms by distributing dynamic assets that are verifiably making real world impact.” To claim PoPs or other Proofs, users can visit the SNI Website or scan QR codes encountered at events. This will direct attendees to the claim process, which involves logging into an account. For those without an account, it can be created easily using an email address, social profiles, or digital wallets. The process is designed for simplicity and efficiency, making it easy to manage and claim Proofs. Once PoPs are collected, the next step is evolving the DOTphin. This can be done by visiting the REAL Evolution page on the REAL portal. The same sign-in credentials used to claim Proofs are required to connect the account. The evolution process begins with the acquisition of the primordial “orbo”, which acts as the starting point; once hatched, it marks the commencement of the DOTphin’s evolution. To evolve the DOTphin, other collected PoPs and Proofs are utilized. On the REAL Evolution page, select the evolve option, choose the Proofs to be applied, and the DOTphin will develop accordingly. Each Proof influences the characteristics of the DOTphin, making it a personalized representation of individual engagement and achievements. The selected Proofs will shape the DOTphin’s evolution, creating a unique avatar. The DOTphin avatar aesthetic is heavily influenced by the artistic style seen in Japanese anime. This design decision creates a significant and relatable connection between the general audience and the digital companion and promotes the idea of caring for an object as it evolves over time. The acclaimed designer behind the art is Daria Smakhtina, from Ephemera One.
