Portfel Ethereum

This project was bootstrapped with Create React App. The live version is modified for the comfort of recruiters. Automatic password entry. Do not use this version for personal use.

About This is the simplest Ethereum wallet on Git. I wrote it myself for recruitment purposes. You can model your wallet on this code. It will be much easier now. Warning! The code is 100% written by me. I didn't use the rare guide written by an experienced programmer. So please, do not enter your realy genuine Ethereum key, and do not sign transactions on it!
