Ethereum-vanity-address

This script lets you generate Ethereum addresses that begin with a custom hexadecimal string

Disclaimers

• I have not benchmarked or optimized the performance of the script.
• It uses the crypto.randomBytes(32) function to generate the private key, which I did not write.

Installation

You will need nodejs to run this script, as well as the ethereum-private-key-to-address package. It can be installed by doing npm install ethereum-private-key-to-address inside the directory. You may want to mkdir node_modules (without cd'ing into it) before installing the package (this can solve a failing installation).

Usage

Ethereum addresses can contain capital letters. If you want to have a strict match, pass s before your string. If you want to have a faster result with the same word by ignoring the case, pass i (BeEf will be treated as a match for BEEF).

node vanity_Eth.js [i or s for case sensitivity] [hex string]

Example

node vanity_Eth.js i B00B5

Output :

Found a match after 1567301 tries !
