Description
Synedrion is an unaudited threshold-signing library based on the CGGMP'24 scheme. It implements ECDSA key generation, auxiliary-information generation and key refresh, presigning, signing, interactive signing, and threshold key resharing. Its protocols run through the manul framework, support identifiable aborts where specified, and may return self-contained evidence of malicious behavior. It currently hardcodes SECP256k1 and does not support multiple shares per party.
