Let's say I've created an account using this code as explained in docs:

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

How do I connect (unlock) to that account later and see all the ETH and other tokens it contains?


1 Answer 1


To get the Ether Balance use web3.fromWei(eth.getBalance(acct), "ether")

The following links might give a guide on checking token balance.



How do I print my account balances and TheDAO tokens from geth

I haven't actually tried it.

  • Thank you for your help. A few things aren't clear to me yet. 1) Once I create an account I get a private key and an encryption method. Should I use the encrypt method on the spot and save its result to use later? 2) when I unlock the account, you mentioned a password, but what about the private key? 3) how do I connect the two commands you wrote together? Does personal.unlockAccount return an 'eth' object?

  • you have to store the key in local storage encrypted using a password and decrypt with the password when needed to sign a transaction. here web3js.readthedocs.io/en/1.0/… to sign a transaction you need only the private key and no password. You use the password to store the private key in secure. as doc says >privateKey - string:This should never be shared or stored unencrypted in localstorage! Commented Nov 8, 2017 at 17:37
  • unlocking an account means getting the private key to sign data or transactions . Commented Nov 8, 2017 at 17:43
  • Not yet, I cannot test it yet since I'm stuck in an earlier step, as you can see here: ethereum.stackexchange.com/questions/30245/…

    I've deleted this question because I solved it by myself. Now I face with another problem, I will test your code as soon as I get my program run at all.
