Question

我想从一个迁移中通过sendTransaction调用智能合约方法。我正在使用松露。在迁移过程中，我创建了一个带有助记符的新钱包。

const seed = bip39.mnemonicToSeed(mnemonic)
const hdk = hdkey.fromMasterSeed(seed)
const addrNode = hdk.derivePath("m/44'/60'/0'/0/0")
const walletAddr = wallet.getAddressString()
await someFactory.createProfile.sendTransaction(detailsHash, { from: walletAddr })

在交易过程中，我收到异常

Returned error: sender account not recognized

如何通过助记符配置文件发送新创建的交易？

然后您可以将提供者设置为您的合同实例

const HDWalletProvider = require("@truffle/hdwallet-provider");
const mnemonic = "Your mnemonic"; //

module.exports = function(deployer) {

  deployer.deploy(SomeFactory).then(someFactory => {
  provider = new HDWalletProvider(mnemonic, "YourURL", 0);

  someFactory.contract.setProvider(provider);

  someFactory.createProfile.sendTransaction(detailsHash, { from:provider.addresses[0] })
  });
};

从迁移签署到智能合约的交易
