 ## Architecture
 
 - `src/lib.rs` — UniFFI exports and module re-exports
-- `src/modules/` — Core modules: scanner, lnurl, onchain, activity, blocktank, trezor, pubky
+- `src/modules/`: core modules: scanner, lnurl, onchain, activity, blocktank, boltz, trezor, jade, hardware_wallet, ur, pubky
 - `bindings/` — Platform-specific binding outputs (ios/, android/, python/)
 - `build.sh`, `build_ios.sh`, `build_android.sh`, `build_python.sh` — Build scripts
 
 ## Key Constraints
 
 - **Version sync**: Version must match across `Cargo.toml`, `Package.swift`, and `bindings/android/gradle.properties`. Use `build.sh -r` to bump all three.
 - **UniFFI**: Public types exposed to bindings are declared in `src/lib.rs`. Follow existing UniFFI patterns when adding new types.
-- **Platform-specific deps**: Trezor uses Bluetooth-only on iOS, USB+Bluetooth on other platforms (see `Cargo.toml` target-specific dependencies).
+- **Platform-specific deps**: Trezor uses Bluetooth-only on iOS, USB+Bluetooth on other platforms (see `Cargo.toml` target-specific dependencies). Jade's serial transport is desktop-only; `serialport` must keep `default-features = false` or CI loses `libudev`.
+- **No cfg-gated UniFFI exports**: bindings are generated from the host library, so a host-only `#[uniffi::export]` would appear in the Swift and Kotlin output while being absent from the device library.
 - **Android build**: `build_android.sh` temporarily modifies `Cargo.toml` crate-type and removes `example/main.rs` during build — don't run concurrent builds.
 - **Android bindings**: Keep `bindings/android/lib/src/main/jniLibs/` untracked. GitHub Actions generates the JNI libraries before publishing the Android package.

 ## Unreleased
 
+- Add Blockstream Jade hardware wallet support: device discovery, connect, PIN unlock via the blind pinserver, extended public key and account export, on-device address verification, message signing, and PSBT signing, over Bluetooth on every platform and USB CDC serial on desktop and Python. Signed PSBTs feed the existing `finalize_psbt` path. The protocol lives in the `jade-client-rs` crate; this repo carries the UniFFI adapter.
+- Add `HardwareWalletVendor.Blockstream` and catalog entries for Jade and Jade Plus. Note that adding an enum case makes exhaustive Kotlin `when` and Swift `switch` statements over `HardwareWalletVendor` non-exhaustive, which is source breaking for consumers.
+
 ## 0.5.14 - 2026-09-02
 
 - Prevent Android ARM32 startup crashes by generating `Int` carriers for direct unsigned 8-bit and 16-bit UniFFI returns while preserving Kotlin unsigned APIs.
