Developing an NFT on Ethereum involves several key steps. First, set up a crypto wallet like MetaMask to store Ethereum (ETH) and pay gas fees. Next, acquire ETH from an exchange to cover transaction costs. Then, choose an NFT standard—typically ERC-721 or ERC-1155—for your digital asset. Write a smart contract using Solidity (Ethereum’s programming language) or use a no-code platform like OpenZeppelin for pre-built templates. Test the contract on a testnet (e.g., Ropsten or Goerli) before deploying it to the Ethereum mainnet. Once deployed, mint your NFT by linking the smart contract to your digital file (art, music, etc.). Finally, list it on an NFT marketplace like OpenSea or Rarible for sale. Ensure proper metadata (name, description, royalties) to maximize visibility and value.
