Rust crates for building Bitcoin wallets and applications that use the Arkade protocol.

This repository contains the Arkade Rust SDK: protocol types, transport clients, wallet integration, fee estimation, and development/test utilities.

The repository also includes ark-client-sample and e2e-tests, which are not published to crates.io.

Use the convenience crate if you want a single SDK dependency:

[dependencies]
ark-rs = "0.9"

Or depend on the crates you need directly:

[dependencies]
ark-core = "0.9"
ark-client = "0.9"
ark-bdk-wallet = "0.9"

Optional ark-rs features:

• client: re-export ark-client
• grpc: re-export ark-grpc
• sqlite: enable SQLite storage support in ark-client
• tls-native-roots: use native TLS roots
• tls-webpki-roots: use webpki TLS roots

• API documentation is published on docs.rs.
• The ark-client-sample crate shows how to wire the client in a CLI application.
• The e2e-tests directory contains integration examples against a local Arkade server.

Common commands are defined in the justfile:

just fmt
just clippy
just test

Generate gRPC code after changing proto files:

just gen-grpc

Run end-to-end tests against a local arkd environment:

just arkd-setup
just e2e-tests

See just --list for the full set of local development, Arkade server, introspector, WASM, and release helper commands.

The SDK supports Rust 1.86.0.

Use the checked-in Cargo-minimal.lock when validating the MSRV:

just msrv-check
