AI agents in the crypto space are autonomous software programs powered by artificial intelligence that can execute on-chain actions, manage portfolios, interact with DeFi protocols, and make decisions based on real-time data without constant human input. They represent the convergence of AI and blockchain technology, enabling use cases like automated trading strategies, smart contract interaction, and decentralized task execution. The AI agent narrative gained significant momentum in 2025 with projects building frameworks for on-chain AI autonomy.
