 LDK Node itself is written in [Rust][rust] and may therefore be natively added as a library dependency to any `std` Rust program. However, beyond its Rust API it also offers language bindings for [Swift][swift], [Kotlin][kotlin], and [Python][python] based on the [UniFFI](https://github.com/mozilla/uniffi-rs/). Moreover, [Flutter bindings][flutter_bindings] are also available.
