Problem Statement
AI agents increasingly manage on-chain assets, but there is no trust infrastructure for agent-to-agent collaboration. If Agent A wants Agent B to optimize its yield, it must grant full token approval — all or nothing. There is no way to scope permissions, enforce limits, or revoke access granularly. This makes autonomous agent cooperation unsafe and impractical for real DeFi use cases. An agent managing a yield strategy can't safely delegate a subset of operations to a specialist agent. A treasury agent can't allow spending yield without risking principal. The current primitive (ERC-20 approve) was designed for humans clicking buttons, not for autonomous agents that need fine-grained, time-bounded, revocable permissions. AgentGate solves this by combining MetaMask's Delegation Framework (ERC-7710 caveats) with a yield-only treasury contract and an MCP server that any agent can connect to — creating the trust layer that agent-to-agent DeFi needs.
AgentGate is agent-to-agent DeFi infrastructure on Base — a hosted MCP server, Solidity treasury contract, and real-time dashboard that let AI agents deposit wstETH, delegate scoped yield-spending rights to each other, and execute autonomous trading strategies. Two agents (Hackaclaw and Merkle) each run Claude Code on separate machines, connect to a shared MCP server over HTTP, and operate against the same on-chain contracts. A third-party agent can self-register via challenge-response (EIP-191 signature verification) without the server ever touching private keys. **What it includes:** - **38 MCP tools across 8 domains**: Identity/Registration (4), Lido staking (7), Treasury management (10), MetaMask Delegations via ERC-7710 (5), ENS/Basenames (2), Uniswap V3 swaps (3), Aave V3 lending + trading recipes (5), Vault monitoring (2) - **Dual-mode agent architecture**: First-party agents (server holds keys, signs txs) and third-party agents (self-registered via challenge-response, server returns unsigned txs for external signing) - **AgentTreasury.sol** — wstETH vault where agents deposit and only accrued yield can be spent. Principal is structurally protected. Uses Chainlink wstETH/stETH oracle for yield calculation. Includes aggregate vault status (totalPrincipal, depositorCount) across all depositors, scoped spender authorization with per-tx and daily caps, and recipient whitelisting. - **Autonomous trading recipes** — delegated agents execute multi-step DeFi strategies: harvest yield → swap via Uniswap V3 → lend on Aave V3 → withdraw profit → transfer back → re-deposit for compounding - **Fork-aware Uniswap routing** — auto-detects environment: queries QuoterV2 directly across all fee tiers on Anvil fork, uses Uniswap Trading API on mainnet - **Live dashboard** — Next.js + wagmi + RainbowKit with agent wallet connect, Basename resolution, real-time toast notifications, bidirectional delegation viewer, Aave V3 position tracking, and interactive MCP Playground - **Human wallet support** — connect via RainbowKit, claim test ETH from signature-protected faucet, swap ETH → wstETH, deposit/withdraw from treasury. All writes via Anvil impersonation. - **Dynamic agent registration** — any agent self-registers via EIP-191 challenge-response. Auto-funded with 1 ETH on fork. Server never stores private keys. - **dry_run simulation** on every write tool - **SKILL.md + lido.skill.md** for agent discovery and Lido mental model
