coins

This project aims to provide high-quality tooling for bip32, bip39, and ledger device communication. It is a toolbox for building signers for blockchain applications. The code runs both natively and in wasm targets for browser and node.

This repo previously hosted a set of transaction construction libraries for UTXO-based chains. You can find much of that work in the archive folder (for now). This is the last commit with that code in the main packages.

Building & running tests

• install rustup
• Run all the tests $ ./build.sh
• build the docs: $ cargo doc

Project Goals

• Support bip32, bip39, and Ledger device comms
• Provide basic tooling to support these use cases
• WASM compatibility in all packages

Project Status

This project is used extensively in the ethers-rs ecosystem. However, much of it is in an alpha/beta state. There will be rough edges, and the interfaces are subject to change.
