在 Coinbase Paymaster 中使用 useWriteContracts 时如何检索交易哈希？

Question

我正在使用 paymaster 服务以及

useWriteContracts

库中的

wagmi

钩子开发 dApp。提交交易后，我收到的不是标准交易哈希，而是一个长 ID。以下是我的设置的概要：

const capabilities = useMemo(() => {
    if (!availableCapabilities || !account.chainId) return {};
    const capabilitiesForChain = availableCapabilities[account.chainId];
    if (
      capabilitiesForChain["paymasterService"] &&
      capabilitiesForChain["paymasterService"].supported
    ) {
      return {
        paymasterService: {
          url: `${document.location.origin}/api/paymaster`,
        },
      };
    }
    return {};
}, [availableCapabilities, account.chainId]);

const { writeContracts } = useWriteContracts({
    mutation: {
        onSuccess: async (id) => {
            console.log("Returned ID:", id);
            // I want to extract the transaction hash here
        },
        onError: (err) => {
            console.log("Transaction Error", err);
        },
    },
});

// Later in the code, I call writeContracts
writeContracts({
    contracts: [
        {
            address: contractAddress,
            abi: contractAbi,
            functionName: "function name",
            args: [function arguments],
            value: tx value,
        },
    ],
    capabilities,
});

返回的

id

不是典型的交易哈希，而是一个长字符串，如下所示：

0x9c5df149aee141828a73238bfd76218b73d4f70cdc1dd2f30362081fbd24b5bf0000000000000000000000000000000000000000000000000000000000014a34

我需要实际的交易哈希来跟踪链上交易（例如，

0x1b1730bfba3a955b76dfdf74b11dc3088edb16c215ca30aaf131c3765c355f56

）。有没有办法从响应中提取交易哈希，或者在将 useWriteContracts 与付款人一起使用时获取它的其他方法？

我提供示例代码。

data = {
  chainId: chain.id,
  __mode: "prepared",
  abi: PresaleContractABI,
  address: "0x9e499f31906674fE5091067Fa83ccbe2851038Aa",
  functionName: "buyToken",
  args: [
    parseUnits(payTokenAmount, global.PROJECT_TOKEN.decimals),
  ],
  value: 0,
};

const preparedData = await prepareWriteContract(data);
const writeData = await writeContract(preparedData);

const txHash = writeData.hash;

const txPendingData = waitForTransaction(writeData);
toast.promise(txPendingData, {
  pending: `Waiting for transaction ${txHash} to be confirmed... 👌`,
});

const txData = await txPendingData;

console.log("Transaction Hash:", txHash);
