How to upload music on OpenSea

To upload music as an NFT on OpenSea, follow these steps:

1. Set Up Your Wallet: Install a MetaMask wallet and connect it to OpenSea. Add the Polygon network if you want to mint for free.
2. Prepare Your Files: Convert your music to MP4 format (as MP3/WAV files are no longer supported) and ensure the file size is under 50MB. Create a custom thumbnail image and write a detailed description.
3. Create Your NFT:
   • Log in to OpenSea.
   • Click “Create” from the top menu.
   • Upload your MP4 file and thumbnail image.
   • Fill in details like name, description, properties (e.g., genre, bitrate), and external links if needed.
4. Choose Blockchain: Select Polygon for gas-free minting or Ethereum if preferred.
5. Mint and List:
   • Click “Create” to mint your NFT.
   • Once minted, click “Sell” to list it on the marketplace.
   • Set your price and listing duration (up to 6 months).
6. Finalize Listing: Sign the transaction in MetaMask to complete the process.

Your music NFT will now be live on OpenSea.
