Transferring ownership of NFT(ERC721)

Question

I'm trying to change the ownership of a requested ERC721(NFT) to another wallet.

I'm using the Mumbai Test Net and ethers.

To do it I need to create the general ERC721 contract using its abi but I can't find it.

In comparison, the ERC20's abi I found easily - link and used it like followed and it's working:

const createERC20Contract = (contractAddress) => {
    const provider = new ethers.providers.Web3Provider(ethereum);
    const signer = provider.getSigner();
    const ERC20Contract = new ethers.Contract(contractAddress, ERC20ABI, signer);

    return ERC20Contract;
}

Where can I find the abi of ERC721 to create the ethers.Contract() ?

Answer 1

Here's a generic ERC721 ABI that I built from the OpenZeppelin implementation. (The bare minimum contract - none of their extensions such as mint and burn tokens.)
