PACE: A New Authorization Framework for AI Agents in Decentralized Finance
PACE has emerged as a new transaction-level authorization framework designed for artificial intelligence agents in decentralized finance (DeFi). It serves as an intermediary between large language model (LLM)-based agents and their on-chain execution, introducing typed transaction intents. A core feature is a deterministic policy verifier, while signed Policy Decision Records (PDRs) cryptographically link approvals to execution bytes. The system also offers replay and expiration protection, enforced on-chain by a Solidity smart account. Measured gas overhead ranges from 29,826 to 31,822, and the framework addresses vulnerabilities related to prompt injection in LLMs.
