BDK Expanding: From Rust Core to Mobile Wallets
BDK is expanding to more places. It starts from a Rust wallet core, into the places where mobile wallets actually ship: Swift, Kotlin, and in 2026 newer libraries like Dart and React Native. This talk is about the engineering work behind that expansion. Using bdk-ffi as the main case study, I’ll walk through how BDK keeps reviewed Rust wallet logic as the source of truth while exposing native-feeling APIs. It will also tie in how this pattern is spreading across the Bitcoin ecosystem as more projects bring Rust libraries into mobile app stacks.
