# Cashu Development Kit

CDK is a collection of rust crates for [Cashu](https://github.com/cashubtc) wallets and mints written in Rust.

**ALPHA** This library is in early development, the api will change and should be used with caution.

## Project structure

The project is split up into several crates in the `crates/` directory:

* Libraries:

    * [**cdk**](./crates/cdk/): Rust implementation of Cashu protocol.

    * [**cdk-sqlite**](./crates/cdk-sqlite/): SQLite Storage backend.

    * [**cdk-redb**](./crates/cdk-redb/): Redb Storage backend.

    * [**cdk-rexie**](./crates/cdk-rexie/): Rexie Storage backend for browsers.

    * [**cdk-axum**](./crates/cdk-axum/): Axum webserver for mint.

    * [**cdk-cln**](./crates/cdk-cln/): CLN Lightning backend for mint.

    * [**cdk-lnd**](./crates/cdk-lnd/): Lnd Lightning backend for mint.

    * [**cdk-strike**](./crates/cdk-strike/): Strike Lightning backend for mint.

    * [**cdk-lnbits**](./crates/cdk-lnbits/): [LNbits](https://lnbits.com/) Lightning backend for mint.

    * [**cdk-phoenixd**](./crates/cdk-phoenixd/): Phoenixd Lightning backend for mint.

    * [**cdk-fake-wallet**](./crates/cdk-fake-wallet/): Fake Lightning backend for mint. To be used only for testing, quotes are automatically filled.

* Binaries:

    * [**cdk-cli**](./crates/cdk-cli/): Cashu wallet CLI.

    * [**cdk-mintd**](./crates/cdk-mintd/): Cashu Mint Binary.
