Fetch.ai’s Autonomous Economic Agents (AEA) Framework is an open-source Python SDK and CLI toolset for creating modular, autonomous agents that can negotiate, transact, and collaborate in decentralized environments. It includes scaffolding commands to generate agent projects, templates for protocols and skills, connection modules to integrate with multiple ledgers (Ethereum, Cosmos, etc.), contract interfaces, behavior and decision‐making components, testing and simulation utilities, and a publishing mechanism to distribute agents on the Open Economic Framework network. Developers leverage its modular architecture to rapidly prototype digital workers for DeFi trading, data marketplaces, IoT coordination, and supply chain automation.

This repository provides a complete suite of multi-agent reinforcement learning algorithms—including MADDPG, DDPG, PPO, and more—integrated with standard benchmarks like the Multi-Agent Particle Environment and OpenAI Gym. It features customizable environment wrappers, configurable training scripts, real-time logging, and performance evaluation metrics. Users can easily extend algorithms, adapt to custom tasks, and compare policies across cooperative and adversarial settings with minimal setup.
