# BTC Balance Checker

> Free, open-source desktop app (Rust + Tauri 2; Windows, macOS, Linux) that watches Bitcoin addresses in bulk and sends a Telegram and/or email alert the first time an address shows a balance. Read-only: it only handles public addresses, never keys. A simplified browser version does one-off checks.
