nano-vanity-address-finder

Finds NANO seeds that generate the desired addresses. Utilizes parallelism to find the seed as quickly as possible.

Usage as Library

In project directory:

npm i nano-vanity-address-finder

Then in code:

const SeedFinder = require('nano-vanity-address-finder')

SeedFinder.findSeedAndAddressWith({ vanityString, vanityStringPosition, cpuCount }).then(({ vanitySeed, vanityAddress }) => {
    console.log(vanitySeed)
    console.log(vanityAddress)
})

Command Line Usage

Install globally from npm with:

npm i -g nano-vanity-address-finder

or install globally from GitHub with:

npm i -g pRizz/nano-vanity-address-finder

Usage:

> nano-vanity-address-finder --help

  Usage: nano-vanity-address-finder [options] <vanityString>

  Finds NANO seeds that generate the desired addresses

  Options:

    -V, --version         output the version number
    -p, --prefix          search for the vanity string as a prefix of the address. This is the default search position.
    -s, --suffix          search for the vanity string as a suffix of the address.
    -c, --contains        search for the vanity string anywhere in the address.
    -a, --aggressive-CPU  use all available cores. By default, uses one less than all cores to reduce CPU starvation.
    -b, --half-CPU        only use half of available cores.
    -h, --help            output usage information

To find an address with a vanity prefix:

nano-vanity-address-finder --prefix myvanity

To find an address with a vanity suffix:

nano-vanity-address-finder --suffix myvanity

To find an address containing a vanity string:

nano-vanity-address-finder --contains myvanity

Example Cost

My NANO address with suffix prizz,

xrb_3fwbzdazf6wmmy17agkzp47f75d5hdm5m91bxexp9auowm8m9a7tsk8prizz

took only an hour to find using an AWS c5.18xlarge instance, which costed about $3.

Longer vanity strings will, of course, take longer and cost more to find.

Security

All seeds are generated with the proper cryptographic functions. Nothing is sent to any backend, but to ensure this, turn off your internet while searching for a seed and uninstall the tool afterwards.

If you want to output to a file instead of standard out, then just redirect the output like so:

nano-vanity-address-finder --contains myvanity > vanityOutput.txt
