  • Support for gas-free minting (Lazy Minting)

Complete selling process: from wallet to listing

  1. Register and connect wallet
    Install the MetaMask extension, then go to the Opensea official website and click “Connect Wallet.”
  2. Create NFT project
    Click “Create”, fill in the work information and upload the file. You can choose to upload images, audio, videos, etc.
