@agentaos/engine

CGGMP24 threshold ECDSA signing scheme for AgentaOS.

Implements the IThresholdScheme interface from @agentaos/core using CGGMP24 (Canetti-Gennaro-Goldfeder-Makriyannis-Peled 2024) threshold ECDSA over secp256k1. Wraps a Rust WASM module for the cryptographic operations.

Install

npm install @agentaos/engine

Usage

import { CGGMP24Scheme, SchemeRegistry } from '@agentaos/engine';

// Direct usage
const scheme = new CGGMP24Scheme();

// Or via registry
const scheme = SchemeRegistry.get('cggmp24');

This package is used internally by @agentaos/sdk and @agentaos/server. Most users should use the higher-level Agenta facade from the signer package instead.

What It Does

• DKG (Distributed Key Generation) -- 3-party key generation ceremony producing 3 shares
• Threshold Signing -- 2-of-3 interactive signing protocol (3 rounds)
• Aux Info Generation -- Pre-computation for efficient signing
• Address Derivation -- secp256k1 public key to Ethereum address

Dependencies

• @agentaos/core -- interfaces and types
• @agentaos/crypto -- Rust WASM binary (CGGMP24 implementation)
