I can't find a way to retrieve the private key / public key / public address for a web3 account loaded via a provider. I have tried the web3.eth.accounts command but I am not getting the private key / public key / public address .

const web3 = new Web3(provider);
web3.eth.accounts

In more details, I would like to have a HD wallet for receiving ethers on different public keys (and later selling them) Following the advice in the doc, I am using truffle/hdwallet-provider for the HD wallet. So now I am trying to retrieve the private key, the public key and possibly the public address via web3js for the provider created via truffle/hdwallet-provider wallet

This is my code which I run several time each time in a new node console in a cmd.

Before starting the node console, I start a cmd with geth --rpc --rpcport 8545 while internet is turned off so that I don't have to download/sync the blockchain

const mnemonicPhrase = 'some words ... '

const HDWalletProvider = require("@truffle/hdwallet-provider");
Web3 = require('web3');


provider = new HDWalletProvider({
  mnemonic: mnemonicPhrase,
  providerOrUrl: "http://localhost:8545",
  numberOfAddresses: 1,
  shareNonce: true,
  derivationPath: "m/44'/0'/0'/0/"
});

const web3 = new Web3(provider);
web3.eth.accounts

There should be a way to retrieve the private/public key via web3.eth.accounts but I am only getting a single address

Thanks a lof for your help!

  • Operating System: windows
  • Ethereum client:
  • Truffle version (truffle version): @truffle/hdwallet-provider@1.4.0 (web3@1.3.6)
  • node version (node --version): v14.16.1

Sorry, web3 does not retrieve private/public keys

However, you can generate an account object that contains a private/public key.

web3.eth.accounts.create();
> {
address: "0xb8CE9ab6943e0eCED004cDe8e3bBed6568B2Fa01",
privateKey: "0x348ce564d427a3311b6536bbcff9390d69395b06ed6c486954e971d960fe8709",
signTransaction: function(tx){...},
sign: function(data){...},
encrypt: function(password){...}

}

  • Thanks for your answer. Yes that is possible but then this address is not part of my truffle wallet/mnemonic. Is there another way/package that I can use to retrieve the private/public key from truffle?
