## What it is
A standalone command-line vanity Bitcoin address generator written in C that searches for addresses matching custom prefixes or regular expressions. It runs multi-threaded on the CPU and is significantly faster than the patched official Bitcoin client.

## Use cases
- generate a bitcoin address starting with a custom prefix
- create a personalized vanity crypto address
- search bitcoin addresses matching a regex pattern
- generate namecoin or testnet vanity addresses
- estimate difficulty of a vanity address pattern
- batch search a list of address prefixes from a file

## When to choose
- you want fast CPU-based vanity address generation without GPU dependencies
- you need regex or multi-pattern prefix search with difficulty estimates
- you need namecoin or testnet address support

## When to avoid
- you need GPU-accelerated generation for very long prefixes
- you want easy private key import into modern Bitcoin Core wallets
- you need actively developed software with recent feature updates

## Facets
- artifact type: cli-tool
