NodeJS vanity ethereum address generator

What is a vanity address?

A vanity address is an address that is personalized and is created respecting a series of parameters.

Examples:

• 0x0000c3Caa36E2d9A8CD5269C976eDe05018f0000
• 0x12345678a36E2d9A8CD5269C976eDe05018fa36E
• 0xdead5678a36E2d9A8CD5269C976eDe05018fa36E

Usage

Install dependencies

npm install

Setup config.json file

{
    "prefix": "abc", // beginning characters
    "suffix": "xyz", // end characters
    "cores":0 // set to 0 to automatically detect core count
}

Run

npm start

public/private address key pairs are outputted to eth_wallet_list.txt as publickey,privatekey

The time to generate an address matching the prefix and suffix depends on the length of prefix + suffix. As the length increases it takes exponentially longer to generate a matching address.

Security

Nothing leaves your machine, and everything is done offline.

Performance

Performance depends on core speed and core count. The more cores you have, the faster you will generate wallets.

Maxing out your core count will make your computer pretty unusable, so set it to like half of your total if you want to use your computer at the same time.
