AI agents are rapidly moving from research toys to on-chain actors. They can already hold keys, parse market data, and submit transactions without a human clicking “Confirm.” That convenience is colliding with DeFi’s brittle edges: token approvals, composability risk, and adversarial prompts.
Recent launches and incidents show what changes when wallets become autonomous. The risk shifts from “What did I sign?” to “What did my agent infer, and under what permissions?” For DeFi users and builders, the threat model must expand to include prompt injection, mis-scoped allowances, and policy bypasses that were once out of scope.
This article maps the new fault lines, using fresh case studies and practical controls you can adopt now—before autonomous flows become your default trading or treasury rails.
