uAgents

What is uAgents?

uAgents is an open-source Python framework developed by Fetch.ai that enables developers to build decentralized, autonomous microservices that can securely communicate, transact, and collaborate on the Fetch.ai Network. uAgents also supports uAgent Adapters, which allow interoperability between uAgents and other agentic or AI frameworks. These adapters act as communication bridges, enabling agents built with LangChain, CrewAI, or custom stacks to interact with the Fetch.ai Network and become discoverable by ASI:One models. Adapters are essential for developers who want to integrate their existing AI pipelines into a multi-agent system without rebuilding from scratch.

Key features

• Python-first Developer Experience: Easy-to-use decorators and simple startup.
• Blockchain Registration: Every agent joins the network via the Almanac smart contract.
• Cryptographic Security: Each agent has its own wallet and encrypted message layer.
• Multi-agent Messaging: Seamless agent-to-agent communication via defined protocols.
• Adapter Bridge: Cross-framework communication using uAgent Adapters.
• Auto-Discovery: Agents become instantly accessible by ASI:One and other registered agents.

Use cases

• Microservices that fetch and process data for LLMs and apps.
• AI assistants that communicate with external APIs or third-party services.
• Messaging bots that support structured and secure workflows.
• Adapter-based agents that act as gateways to LangChain/CrewAI/Flask agents.
• Core protocol layer for agents built in Flockx or deployed in Agentverse.
