AI agents are revolutionizing decentralized finance (DeFi) as they manage liquidity, optimize yield, and execute trades 24/7. As these AI agents become mainstream financial operators, the need for secure infrastructure is paramount. However, existing wallets are struggling to keep up with the demands of AI agents in DeFi. The lack of standardized infrastructure poses a critical limitation for automated operations in the DeFi space. Without proper guardrails, AI automation in DeFi can lead to catastrophic risks such as unauthorized access and fund drainage. Recent incidents like the exploits on Banana Gun and Aixbt highlight the vulnerabilities in the current automation infrastructure. Legacy wallets are ill-equipped to support autonomous agents due to their static architecture and lack of programmable features. To address these issues, programmable permissions are crucial to ensure secure and scalable automation in DeFi. By enabling session-based permissions and cryptographic verification of agent actions, users can delegate control without compromising security. Programmable infrastructure not only mitigates risks but also expands access to advanced DeFi strategies for all users. As institutional interest in DeFi grows, secure automation with verifiable guardrails will become a standard requirement. The future of DeFi lies in building infrastructure that can support AI agents while maintaining transparency and user sovereignty. The question is not whether AI agents will participate in DeFi but whether the necessary infrastructure will be in place to guide them in serving users effectively. Sean Li, co-founder of Magic Labs, emphasizes the importance of rebuilding wallets to support the automation revolution in DeFi. This article provides insights into the evolving landscape of AI agents in DeFi, highlighting the need for secure and programmable infrastructure to drive the future of decentralized finance in India.
