A Rust-C FFI library exposing composite functionality from rust-bitcoin & bdk; to create cross-platform descriptor wallets.
Currently used by Stackmate Wallet.
Immense love to our friend and sponsor Prashant Balani for being patient and supportive throughout the 3 years of R&D that was required to make this project come to life!
Massive thanks to the bdk & cyphernode teams for all the support and feedback which saved us a lot of time and improved the quality of our work.
The entire ffi uses a string interface; defined in src/lib.rs
Inputs are converted into native rust types as the first sanitization step.
Native types are then used in pure rust modules.
All native structs being returned (responses and errors) impl a c_stringify method which converts the native struct into stringified JSON outputted as a CString.
Test everything!
bash tests/test.sh
Test individual units with printing.
cargo test -- --nocapture <test_name>
bash resources/build.sh
Currently only supports android builds.
Binaries are zipped into resources/builds.zip.
This library expects the client to build a policy (string) by themselves - refer to http://bitcoin.sipa.be/miniscript/ for more info.
More documentation can be found in resources/docs.
We are looking for active contributions in the following areas:
General code review
IOS builds
Taproot support
Neutrino support
Lightning support
