Can I integrate NFT minting and MetaMask wallet with a Webflow-designed website for my ERC-721 token collection?

Yes, you can integrate NFT minting and MetaMask wallet functionality with a Webflow-designed website, but it requires embedding custom JavaScript and connecting it to a backend or smart contract hosted externally.

1. Design the Frontend in Webflow

• Use Webflow to design your site layout, landing page, and mint button.
• Add a custom button element for minting (e.g., "Mint NFT").
• Use Embed elements (+ Add » Embed) to insert JavaScript snippets for wallet connection and smart contract interaction.

2. Set Up and Deploy Your Smart Contract

• Create your ERC-721 token contract using Solidity.
• Deploy the contract to Ethereum or a compatible chain (e.g., Goerli, Polygon) using tools like Hardhat or Remix.
• Make sure the smart contract has a mint function that is callable by users (e.g., mint() or safeMint()).

3. Enable MetaMask Connection

• Use Web3.js or Ethers.js to connect to MetaMask inside your Webflow site.
• Add the JS code via the Before tag section in Webflow’s Page Settings or use the Embed element.
• Detect MetaMask with window.ethereum and request access with ethereum.request({ method: 'eth_requestAccounts' }).

4. Mint NFTs from the Site

• After wallet connection, configure JS to call your contract’s mint function, passing necessary arguments (e.g., tokenURI, payment).
• Ensure you provide gas estimates, handle user signature events, and show confirmation/error messages.
• All logic for interacting with the smart contract will happen in the custom JS you add to your Webflow site.

5. Host Metadata and Images (IPFS or Centralized)

• Store NFT artwork and metadata on IPFS (e.g., via Pinata or NFT.Storage) or on a standard server.
• Your tokenURI should point to this hosted metadata.

6. Handle CORS & Security

• Note that Webflow can’t host asynchronous backend functions, so your interaction must rely on static JavaScript or be delegated to external services (e.g., AWS Lambda, third-party services).
• Any sensitive logic like signature verification or royalties should be handled via on-chain logic within your deployed the smart contract.

Summary

You can integrate NFT minting and MetaMask wallet into a Webflow website by embedding custom JavaScript using Ethers.js or Web3.js that connects to your ERC-721 smart contract. While Webflow handles your frontend design, all blockchain interactions must be done via external scripts and smart contract calls.
