对EIP-712数据进行签名时签名无效

Question

我正在尝试对USDC合约(实现EIP-3009(调用transferWithAuthorization。要做到这一点，我需要签署交易数据，然后执行交易，但我得到了错误：Fail with error 'FiatTokenV2: invalid signature'

事务错误示例。

有什么想法吗？

const { ethers } = require('ethers');
const abi = require('./abi');
async function main() {
/* Generate Signature */
const sendingWallet = ethers.Wallet.createRandom();
const sendingAddress = await sendingWallet.getAddress();
const types = {
TransferWithAuthorization: [
{ name: 'from', type: 'address' },
{ name: 'to', type: 'address' },
{ name: 'value', type: 'uint256' },
{ name: 'validAfter', type: 'uint256' },
{ name: 'validBefore', type: 'uint256' },
{ name: 'nonce', type: 'bytes32' },
],
};
const domain = {
name: 'testapp',
version: '1',
chainId: '5',
verifyingContract: '0x07865c6E87B9F70255377e024ace6630C1Eaa37F', // USDC Contract
};
const message = {
from: sendingAddress,
to: '0x1bC152F3E47CC7baDF5629bc77CBEf9DaE813843', // Receiver wallet
value: 100000,
validAfter: 0,
validBefore: Math.floor(Date.now() / 1000) + 3600, // Valid for an hour
nonce: ethers.utils.hexValue(ethers.utils.randomBytes(32)), // 32 byte hex string
};
const signature = await sendingWallet._signTypedData(domain, types, message);
console.log(signature);
const { v, r, s } = ethers.utils.splitSignature(signature);
console.log(v, r, s);

/* Execute transaction */
// Throw away wallet :)
const wallet = ethers.Wallet.fromMnemonic(
'youth tool amount venue exact birth opinion derive lend charge roof food',
);
const connection = new ethers.providers.InfuraProvider(
'goerli', // or 'ropsten', 'rinkeby', 'kovan', 'goerli'
'x', // Infura API Key
);
const signer = wallet.connect(connection);
const contract = new ethers.Contract(
'0x07865c6E87B9F70255377e024ace6630C1Eaa37F',
abi,
signer,
);
const res = await contract.transferWithAuthorization(
message.from,
message.to,
message.value,
message.validAfter,
message.validBefore,
message.nonce,
v,
r,
s,
{
gasLimit: 1000000,
},
);
console.log(res);
const receipt = await res.wait();
console.log(receipt);
}
main();

截至今天(2023年4月20日(，goerli上USDC合同的域分隔符为0x64b8869f66ce3d062d2e4b6b2819c6d5e2d3c7ebeb7025e8c819955f2c749012，这是的结果

name: 'USD Coin',
version: '2',
chainId: 5,
verifyingContract: '0x07865c6E87B9F70255377e024ace6630C1Eaa37F'

问题使用了无效的名称和版本。这可能是问题的一部分。

请注意，由于合同是可升级的，域分隔符可能是在过去的升级中修改的。
