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.

Agents-Yoti is an open-source module in the Fetch.ai agent framework designed to streamline digital identity flows within autonomous agent networks. The Yoti Agent interacts with Yoti’s SDK and API to prompt users for identity proofs—such as age verification, passport details, or biometric attestations—offering a standardized mechanism to collect, validate, and store user credentials. It handles session management, cryptographic signing, and secure data transfer, then publishes the verification outcome to the Fetch.ai ledger. By encapsulating the complexity of identity provisioning, Agents-Yoti enables developers to embed compliant authentication protocols into AI-driven supply chains, finance applications, or any decentralized service requiring robust user verification without building identity infrastructure from scratch.
