A commnand-line vanity address generator for Grin. I made this mostly for fun and to familiarize myself with the various Grin libraries written in Rust. The code is currently a lot slower than expected since deriving a slatepack address from a seed seems to be ~1000x slower that deriving it from a raw public key.

Example usage

The output below depicts an adrress found with the pattern grin1test and its corresponding seed.

$ grin-vanity --threads 30 --pattern grin1test --interval 180

Estimated Time

Guessing a private key with the chosen prefix has an element of luck to it. The following table depicts a rough estimate on what should be expected on a Ryzen 5950x using 30 threads. Your results may vary.

Build
