Hi everyone, I'm using web3 in nodejs to connect to ropsten. Is there a way to load an existing wallet to via nodejs?

@roque1776 what do you mean by that? there is no way you can negate the current exchange rate for ether, so you just have to make your app as efficient as possible.
@djordan28054 what contract code? if you mean the token contract from the ethereum website: noone is having any problem with that as it is running smoothly. if you are experiencing problems with the code then your development environment is the cause of the problem.

@squlio-jmul web3 doesn't have this feature as of now. but you could try this module for node.js: https://www.npmjs.com/package/ethereumjs-accounts-node
with that you can create and load accounts

Thanks @ENiG87 I will take a look at that
another question for you
So im trying to write my own version of oracle
So a function in my contract will broadcast and event. A listener in the console will receive that event and do whatever it needs to do, and then fire a callback
is it possible that the from param in the sendTransaction is coming from a contract address?

for example mycontract.callback({from: someOtherContractAddress});
I keep getting Error: unknown account
My guess is the from address can only be any address listed in my eth.accounts?
