caravan-config

This is a proof of concept for now for using bdk to convert between descriptors and a caravan compatible wallet configuration.

Installation

1. clone
2. install rust toolchain and cargo install wasm-pack
3. npm install in the main directory
4. cd to the caravan-rs directory and wasm-pack build -t nodejs to build the pkg/ directory (not clear yet if nodejs is the right target or how to make it more flexible)
   1. You might need to install llvm/clang
   2. Will also need to setup paths to build libsecp

export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
# for older homebrew installs
# export PATH="/usr/local/opt/llvm/bin:$PATH"
export CC=/opt/homebrew/opt/llvm/bin/clang
export AR=/opt/homebrew/opt/llvm/bin/llvm-ar

Usage

You can use npm scripts from the main directory to do all building

$ npm run build

This will cd into the rust directory, build packages for web and node targets, and then build the artifacts for the js library to be packaged and used.

$ npm run test

This will run the TypeScript tests only.

Web

You'll need to make sure that the web environment this is used in supports wasm. For example, if you're using in a vite.js project you'll need the vite-plugin-wasm plugin.

Also note that all functions exported are async and need to be awaited since they will load up the wasm modules to be used (this way consumers of the library don't have to worry about loading up the modules themselves)

API

NOTE: This is subject to change as this is still very much alpha

Only two functions exported currently:

encodeDescriptors

Takes a config for a multisig wallet and encodes it into the two corresponding descriptors

decodeDescriptors

Take two descriptors and convert them into a multisig wallet config object. This will make it possible to determine and parse the wallet type (e.g. P2SH) and the key origins.
