Stellar Vanity

A simple CLI tool to generate Stellar vanity addresses.

Vanity Address: similar to a vanity license plate, a vanity cryptocurrency address is an address where either the beginning (prefix) or end (postfix) is a special or meaningful phrase. Generating such an address requires work.

Benchmarking

Benchmarking is performed by using criterion.rs via cargo bench, which executes the benches/benchmark.rs file.

How can I Benchmark?

Ah, thanks so much! I have limited computing power (if you do too... do not attempt, will likely be long and costly)

1. git clone https://github.com/robertDurst/stellar-vanity-address-generator.git
2. cd stellar-vanity-address-generator
3. cargo bench

Benchmark Configurations:

• as many threads as possible (see note below)
• varied samples per method
• 1 - 3 prefixes

Note: this uses num_cpus::get() from num_cpus to determine the maximum number of cores availible. If that is not desired, you'll have to dig in and set this number manually... or open a pr if you know how to pass CLI args to cargo bench :)

How to use library:

use stellar_vanity::vanity_key::AddressGenerator, deserialize_public_key};;

let mut generator: AddressGenerator = Default::default();
let keypair = generator.find(|key| {
    let public = deserialize_public_key(key);
    // any conditions go here
    public.as_str().ends_with("RUST") // e.g. find address with the "RUST" suffix
});

This will continuously loop until a key with the desired properties is found. Once the vanity address is found, a keypair will be returned, which may be deserialized with deserialize_public_key and deserialize_private_key respectively. Note, this is a synchronous function.

How to use CLI:

cargo run -- [--postfix=<POSTFIX>] [--prefix=<PREFIX>] [-c=<NUMBER_OF_THREADS>]

Either `--postfix` or `--prefix` option is required, while thread count is optional.

As an example, the following looks for an address ending in pizza with 8 threads:

cargo run -- -c=8 --postfix=pizza

The --prefix and --postfix options will search using RegEx expressions. You may need to enclose the expression in quotes when running from the command-line.

The following looks for an address ending in joe with a number before it, using 8 threads:

cargo run -- -c=8 --postfix='[0-9]joe'
