Ganache-cli Fork – How to Unlock Account for Transactions

ganache-clitruffle

I'm trying to use ganache-cli on a fork of the Main Network.

I use the following command to start ganache.

ganache-cli –fork https://mainnet.infura.io/v3/MY_API_KEY — unlock 0x6EBaF477F83E055589C1188bCC6DDCCD8C9B131a

Ganache will still give me the 10 account and non of them have this address.

This account is not mine but has a lot of ether in it. So how do I work on the fork with this account?

Truffle will also see me as the first ganache account. And contract deployment will be made under this address and not the one I unlocked.

How do I work from this account without the private key?

It' seam like truffle isn't seeing this unlocked account.

You need to specify the "from" sender account.

If you're trying to make a contract interaction (functional call), then you want something like

MyContract.someFunction(arg1, arg2, { from: "0x6EBaF477F83E055589C1188bCC6DDCCD8C9B131a" })

If you're trying to send ETH from the unlocked account, then you want something like

const someAccount = "0x6635f83421bf059cd8111f180f0727128685bae4"
web3.eth.sendTransaction({from: "0x6EBaF477F83E055589C1188bCC6DDCCD8C9B131a", to: someAccount, value: "1000000000000000000"})

You'll need to add a development section to the networks section in your project's truffle.js:

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 7545,
      network_id: "5777"
    }
  }
};

Make sure you get the port and network ID correct. Those are the defaults, so if you change them in Ganache you will need to change them here as well.

To use this specified network, after building the contract files, you'd use the command

truffle migrate --network development

Since you are using HDWalletProvider it will only support accounts derived from the mnemonic. It doesn't know the private key required to sign messages from other addresses.

As alternative you pass to HDWalletProvider an array of private keys.

var privateKeys = [
  "3f841bf589fdf83a521e55d51afddc34fa65351161eead24f064855fc29c9580",
  "9549f39decea7b7504e15572b2c6a72766df0281cea22bd1a3bc87166b1ca290",
];
var provider = new HDWalletProvider(privateKeys, "http://localhost:8545", 0, 2); //start at address_index 0 and load both addresses
