What programming languages background is required to publish a web page that has a button on it, which when pressed, invokes MetaMask for the user to publish an ERC-721 token to Ethereum mainnet?
Nevermind the input fields of upload image and set metadata, just more curious about the HTML or Javascript code that goes into making that button that 1) calls in MetaMask to create a transaction, then 2) deploys the NFT to mainnet when the transaction completes. Example script would be helpful.
