Agents & Automation

Uagents

uAgents is a Python library developed by Fetch.ai that facilitates the creation of autonomous AI agents capable of executing tasks based on schedules or event triggers. These agents automatically register on the Fetch.ai blockchain network via the Almanac smart contract, enabling seamless network connectivity. The framework provides cryptographic security for messages and wallets, ensuring protection of identities and assets. It supports agent communication, storage, synchronous interactions, and broadcasting, integrating with the broader Fetch.ai ecosystem and agent marketplace. The library is open-source, lightweight, and compatible across major operating systems including Ubuntu/Debian, MacOS, and Windows.
