uAgents is an open-source multi-agent framework developed by Fetch.ai for creating decentralized autonomous AI agents. It supports peer-to-peer messaging over libp2p, agent lifecycle management, smart contract integration, and reinforcement learning. Developers can define custom agents in JavaScript, deploy them on distributed networks, and enable them to discover, advertise, and negotiate tasks. The framework's modular design facilitates extensibility through plugins, allowing seamless integration with blockchain, oracles, and on-chain/off-chain environments.

What is uAgents?
uAgents is a modular JavaScript framework that empowers developers to build autonomous, decentralized AI agents which can discover peers, exchange messages, collaborate on tasks, and adapt through learning. Agents communicate over libp2p-based gossip protocols, register capabilities via on-chain registries, and negotiate service-level agreements using smart contracts. The core library handles agent lifecycle events, message routing, and extensible behaviors such as reinforcement learning and market-driven task allocation. Through customizable plugins, uAgents can integrate with Fetch.ai’s ledger, external APIs, and oracle networks, enabling agents to perform real-world actions, data acquisition, and decision-making in distributed environments without centralized orchestration.
