Delegator Agent Toolkit
Eidolon's Team
Problem Statement
AI agents currently rely on binary token approvals that grant unlimited spending power, creating unacceptable risk for owners. There is no standard, revocable, intent-bound delegation mechanism that allows humans to give agents limited, auditable permissions onchain. This leads to either no agent autonomy or excessive exposure to theft and misuse.
An autonomous AI agent needs limited, revocable permission to act onchain. Existing approvals are binary and risky. This toolkit introduces intent-based delegations using ERC-7715 and the MetaMask Delegation Framework. Humans create delegations with explicit constraints: allowed targets, function selectors, value caps, expiry, and an intentHash. Agents can further sub-delegate with tighter limits, forming delegation chains. The intentHash enables future zkSNARK proofs that demonstrate knowledge of the human's intent without revealing it. The system includes a Solidity registry (DelegatorAgent.sol), a Node.js client for preflight checks, and a React dashboard. It solves a critical missing piece for safe, controllable AI agents in web3.
