来自 web3 的 MintTo 合同给出错误 - ERC721：转移到非 ERC721Receiver 实施者

Question

我是区块链技术的新手。 我正在尝试创建一个合同，然后使用 web3 python 库创建一个令牌来进行合同。

我可以创建一个合同。 这是rinkeby中的合同链接

https://rinkeby.etherscan.io/address/0x466086b7002d6836c2e4ca05472ded70a7f5213b

每当我尝试为此铸造令牌时。 我得到以下错误

web3.exceptions.ContractLogicError: execution reverted: ERC721: transfer to non ERC721Receiver implementer

这是我进行铸币的代码。

Answer 1

我认为第一个错误是当你建立一个事务时，你需要传递一个 object：

 tx_hash = contract.functions.mintTo(Web3.toChecksumAddress('0x466086b7002d6836c2E4Ca05472deD70A7f5213b')).buildTransaction({

        "chainId": chain_id,
        "gasPrice": w3.eth.gas_price,
        "from": whatever_address,
        "nonce": nonce_value,
})

链 ID

NETWORK_CHAIN_IDS = {
  1: "Ethereum Main Network",
  3: "Ropsten Test Network",
  4: "Rinkeby Test Network",
  5: "Goerli Test Network",
  42: "Kovan Test Network",
  56: "Binance Smart Chain",
  1337: "Ganache",
};
