onChain-agent provides a comprehensive toolset for building self-driving blockchain agents powered by AI. It continuously listens to on-chain events such as token transfers, governance proposals, or price feeds, then uses integrated large language models to interpret data, generate decision plans, and trigger transactions. The framework includes configurable strategy templates for DeFi arbitrage, market making, liquidity provision, and governance voting. It manages private keys securely, ensures risk checks, and logs all activities for auditability. Developers extend functionality via plugin modules supporting custom chains, data oracles, and advanced AI models. Real-time monitoring dashboards and alerts help users track performance.
