BDK Expanding: From Rust Core to Mobile Wallets
summary
BDK ships a Rust wallet core and exposes it to mobile via a generated FFI bridge so the Rust libraries remain the single source of truth. The engineering uses bdk-ffi built on UniFi to generate Swift, Kotlin and Python bindings and recently added production-ready BDK React Native (1.0) and BDK Dart (1.0 RC). Real wallets (Bull Bitcoin and others) run at scale, challenges solved include type conversion, packaging, reproducible builds and avoiding duplicate wallet implementations.
