ethvanity

ethvanity is a fast and simple command line tool to generate so-called "vanity" Ethereum addresses.

These are addresses that have a certain pattern - typically, they are specific suffixes or prefixes to the hex string that represents the address.

For example, say you want your address to start with 3 zeros. Such an address could be 0x00009cd4D5c81D51c53b61344C31266F8A1C2363. Of course, there are many such addresses. The longer your prefix, the longer it'll take to generate such a vanity address, since the best "algorithm" is to simply generate a random private key, from that get the public key, and from that get the address - which is the last 20 bytes of the keccak-256 hash of the public key.

How To Use

ethvanity is simple to use - simply run:

go install github.com/butcher-of-blaviken/ethvanity

Or clone the repository locally on your machine and run:

# optional, could use go run main.go as well
go build
# omit the './' if you ran 'go install'
./ethvanity -cmd generate -desired-pattern 000 -pattern-position prefix

The output is an address printout with the desired pattern and the associated private key in hexadecimal.

Important To Note

• This tool does not require the internet. Indeed, it is recommended you cut off your computer from the internet when executing this tool, just in case :-).

• The longer your prefix/suffix pattern is, the longer it'll take to find your desired address. A simple rule of thumb is that each extra character will multiply the number of iterations by a factor of 16, since there are 16 different possibilities for each hexadecimal character.
