如何解码 Polygon 网络中智能合约的函数名？

Question

我已经部署了合约（不是我的），没有提供abi。

交易中使用的输入数据：

0xd1700e6c0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

谁能帮忙，如何直接从web3调用这个函数？或者如何找出它的名字。据我了解，当您调用合约函数时，您会写：contract.methods.func().send()。但是，如果我只有 methodId，如何 call/send 发挥作用？

Answer 1

您可以在 data 字段中创建一个包含函数选择器（以及函数参数）的原始交易，对其进行签名，然后将其发送给您的节点提供商以将其广播到网络。

// the sender private key needs to be added to web3 `accounts.wallet`
// see the blue "note" card in the docs for more details

await web3.eth.sendTransaction({
    from: senderAddress,
    to: contractAddress,
    data: "0xd1700e6c..."
});
