BDK
A modern, lightweight, descriptor-based wallet library written in Rust. Higher level, with wallet functionality. Supports Miniscript descriptors.
rust-bitcoin crate
Lower level, lighter library for assembling transactions, generating addresses etc.
musig2 crate
Still in beta but could be used by us.
This crate provides a flexible rust implementation of MuSig2, an optimized digital signature aggregation protocol, on the secp256k1 elliptic curve.
MuSig2 allows groups of mutually distrusting parties to cooperatively sign data and aggregate their signatures into a single aggregated signature which is indistinguishable from a signature made by a single private key. The group collectively controls an aggregated public key which can only create signatures if everyone in the group cooperates (AKA an N-of-N multisignature scheme). MuSig2 is optimized to support secure signature aggregation with only two round-trips of network communication.
LND MuSig2 implementation
frost crate
This should work with bitcoin as it supports secp256k1. IIUC frost supports schnorr treshold signatures, unlike N-of-N in MuSig2, Frost can do M-of-N.
Roast also seems really useful but there is no production ready implementation yet.
bitcoinjs-lib
A javascript Bitcoin library for node.js and browsers. Written in TypeScript, but committing the JS files to verify.
Can look at this library. Example taproot spending using bitcoinjs-lib: https://github.com/bitcoinjs/bitcoinjs-lib/blob/master/test/integration/taproot.spec.ts
