AI-OnChain-Agent integrates OpenAI GPT models with Web3 protocols to create autonomous blockchain agents. It connects to Ethereum networks via configurable RPC endpoints, uses LangChain for prompt orchestration, and Ethers.js/Hardhat for smart contract interactions. Developers can specify trading or governance strategies through prompt templates, monitor token metrics in real time, sign transactions with private keys, and execute buy/sell or stake/unstake operations. Detailed logs track decisions and on-chain results, and the modular design supports extending to oracles, liquidity management, or automated governance voting across multiple DeFi protocols.

EthLisbon provides a ready-to-use autonomous agent architecture that interacts with Ethereum smart contracts to conduct auctions, bids, and trades automatically. It listens to on-chain events, processes data feeds off-chain, and executes customized strategies based on configurable parameters. The modular codebase allows developers to extend skills, integrate additional oracles, and deploy multiple agent instances. Retry and state-management mechanisms ensure resilience, while built-in logging and monitoring tools give real-time visibility into agent operations.
