NFT所有权转移(ERC721)

Question

我正在尝试将请求的 ERC721(NFT) 的所有权更改为另一个钱包。

我正在使用孟买测试网和以太币。

为此，我需要使用它的 abi 创建通用 ERC721 合约，但我找不到它。

相比之下，我很容易找到 ERC20 的 abi - link 并按照以下方式使用它并且它正在运行：

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

    return ERC20Contract;
}

在哪里可以找到 ERC721 的 abi 来创建 ethers.Contract() ？

Answer 1

这是我从 OpenZeppelin implementation 构建的通用 ERC721 ABI。（最低限度的合同 - none 他们的扩展，例如铸币和销毁代币。）
