## What it is
A Rust library implementing {t,n}-threshold ECDSA digital signatures using multi-party computation protocols, supporting key generation and distributed signing across multiple protocols. It was built for cryptography engineers to experiment with MPC and threshold signature schemes used in crypto wallets.

## Use cases
- implement threshold ECDSA signing in Rust
- build a multisig or threshold signature crypto wallet
- split an ECDSA private key into secret shares
- experiment with MPC signature protocols like GG19
- sign Bitcoin or Ethereum transactions with distributed keys

## When to choose
- you need a Rust implementation of threshold ECDSA for research or experimentation
- you want to study multiple MPC signing protocols with different security tradeoffs
- you're building a proof-of-concept threshold wallet

## When to avoid
- you need production security updates - the repo is explicitly unmaintained with no fixes
- you want Zengo's production MPC code - use their gotham-city repository instead
- you need a non-Rust language without a wrapper SDK

## Facets
- artifact type: library
- maturity: abandoned
- function: cryptography, security, sdk
- domain: blockchain, security
- platform: rust, cross-platform
- tags: threshold-signatures, ecdsa, mpc, tss, secret-sharing, secp256k1, digital-signatures, cryptography, cryptocurrency
