ERC-721 NFT

This app introduces an ERC-721 token contract and demonstrates how to use it, including getting the total supply and holder balance, listing all NFTs from the collection and NFTs from the connected address, and how to transfer NFTs.

The ERC-721 Token Standard introduces a standard for Non-Fungible Tokens (EIP-721), in other words, each token is unique.

The ERC-721 token contract is implemented using the ERC-721 token implementation from OpenZeppelin.

The ERC-721 token implementation uses the ERC-721 Enumerable extension from OpenZeppelin to list all tokens from the collection and all the tokens owned by an address.

Below you can mint an NFT for yourself or to another address.

You can see your balance and your NFTs, and below that, you can see the total supply and all the NFTs minted.
