Truffle contract deployment failed, invalid sender

Question

I'm trying to deploy a contract to the ropsten testnet using truffle, but I get the following error:

Deploying 'Migrations'
   ----------------------

Error:  *** Deployment Failed ***

"Migrations" -- invalid sender.

    at /home/usr/.npm/lib/node_modules/truffle/build/webpack:/packages/deployer/src/deployment.js:365:1
    at process._tickCallback (internal/process/next_tick.js:68:7)
Truffle v5.2.5 (core: 5.2.5)
Node v10.19.0

When deploying to ganache locally, it works fine. Also I'm pretty sure my truffle-config.js is correct, it's the same as all the online tutorials, but since I'm here, I guess I'm not completely sure :). The address that hd-wallet is using is also correct (verified with the console.log statement in truffle-config.js) and it has 5 ETH balance, so more than enough. I have 2 migration scripts, it gives exactly the same error with each script.

truffle-config.js:

require("dotenv").config();
const HDWalletProvider = require("@truffle/hdwallet-provider");

module.exports = {
    networks: {
        ropsten: {
            provider: () => {
                var provider = new HDWalletProvider({
                    mnemonic: process.env.MNEMONIC,
                    providerOrUrl: `https://ropsten.infura.io/v3/${process.env.INFURA_KEY}`,
                    derivationPath: "m/44'/60'/0'/0/",
                    addressIndex: 0,
                });
                console.log(provider.getAddress());
                return provider;
            },

    function deposit(address payee) payable public onlyAgent {

Answer 1

Try a different version @truffle/hdwallet-provider Works for me with 1.2.3

npm uninstall @truffle/hdwallet-provider npm install @truffle/[email protected]

With the latest version (1.2.4) there was the same error (invalid sender).

Answer 2

According to my observation, this issue only occurs when you try to deploy any contract on ropsten testnet. If you're deploying with a local node like running with ganache-cli, it functions well even with the latest version (>1.2.3)

The reason here is they change the constructor method to add a chainId parameter to specified which chain you're signing with your transaction.

Solution: Update your code of initializing the HDWalletProvider.

    ropsten: {
      provider: () =>
        new HDWalletProvider({
          mnemonic,
          providerOrUrl:
            'wss://ropsten.infura.io/ws/v3/.....',
          chainId: 3,
        }),
      network_id: 3, // Ropsten's id
      gas: 5500000, // Ropsten has a lower block limit than mainnet
      confirmations: 0, // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 200, // # of blocks before a deployment times out  (minimum/default: 50)
      skipDryRun: true, // Skip dry run before migrations? (default: false for public nets )
    },

This works fine with me on ropsten

Check this out: https://github.com/trufflesuite/truffle/issues/3935

Seems that truffle may not be properly eip 155 compliant. A PR was merged to help but I don't think this issue is yet resolved from the HDWallet end.

Answer 4

I am using @truffle/hdwallet-provider 1.3.0 and still got the same error.

Got it fixed by changing the initialization of HDWalletProvider.

ropsten: {
    provider: function () {
        return new HDWalletProvider(
            {
                privateKeys: ["YourPrivateKey"],
                providerOrUrl: "https://ropsten.infura.io/v3/InfuraKey",
                chainId: 3,
            }
        )
    },
    network_id: '3',
}

(Replace YourPrivateKey and InfuraKey with your private key and infura api key)

Answer 5

As an alternative solution, inside truffle-config.js use:

const HDWalletProvider = require('truffle-hdwallet-provider');

instead of

const HDWalletProvider = require('@truffle/hdwallet-provider');

It's just another way of downgrading the @truffle/hdwallet-provider while your package.json can still have:

"dependencies": {
    "@truffle/hdwallet-provider": "^1.3.1"
}
