2026-07-01 03:01:00AI Agent Era On-Chain Security: When Transactions Shift from Humans to Agents, How Web3 Redefines Safety Boundaries
A joint research report by Web3Caff Research and SlowMist, analyzing the new on-chain security challenges as AI Agents enter Web3. Using real cases including Bankr/Grok Morse code attack, PocketOS database deletion, LiteLLM supply chain poisoning, and Vercel/Context.ai breach, the article reveals attack surfaces expanding from private key theft to a five-layer composite risk targeting model goals, memory, toolchains, wallet authorization, and payment paths. It categorizes defense solutions from Cobo, Fystack, Thirdweb, Coinbase, OKX, Binance, GoPlus, and SlowMist, and proposes six design principles—intent-execution separation, isolation, verifiable UI, toolchain governance, payment boundaries, and rapid incident response—to help projects build security infrastructure for the Agent era.
