This web page helps you create an NFT on the Stellar network.
The file and description are uploaded directly from your browser to the IPFS network, and then referenced along with their hashes in a locked account on the Stellar network. An asset with the symbol you choose will be issued by that locked account and will represent ownership of the NFT.
The file and description uploaded to IPFS are ephemeral. Use an IPFS pinning service to pin them in the IPFS network so they aren't dropped.
Your Stellar account will create the locked account and the locked account will issue your account the NFT asset in a single atomic operation. Your account will pay the issuing account reserve and all transactions fees. The reserve will not be reclaimable.
Once the NFT is created you can send or sell your NFT using a wallet or DEX app.
