When I tested on ganache-cli at local, I could test on 'truffle console development' with some accounts which ganache-cli gave. But at rinkeby, I can't use function_name(argumets, {from: specific rinkeby account}) form. Is it possible to set the specific account on 'truffle console rinkeby(and mainnet also)'? (Something like using web3.eth. thing) If it is, how can I set that?

  • You can specify the from in the truffle.js configuration file, or in each function call. How do you connect to rinkeby? – Ismael Dec 22 '18 at 5:41
  • I did like this. rinkeby: { provider: function() { return new HDWalletProvider(mnemonic, "https://rinkeby.infura.io/<my_endpoint>", 0); }, network_id: 4 }. I deployed with the 'mnemonic' here, and I wanted to test on 'truffle console rinkeby' with other specific account. Is it impossible to do what I want? @Ismael – Jung Chun Dec 22 '18 at 7:27

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
  • Oh it's cool. By the way, I wanted to know the possibility(and if it's possible, plus the method to do that) to set the other account when using truffle console at rinkeby/mainnet. So are you saying this is not possible? – Jung Chun Dec 22 '18 at 15:51

    Truffle console uses the provider from the configuration file. With HDWalletProvider then you are limited to those address derived from the mnemonic. – Ismael Dec 22 '18 at 20:49
