ComplianceYieldTreasury

ComplianceYieldTreasury is a DeFi primitive that structurally separates principal from yield at the smart contract level. An agent stakes wstETH (Lido's wrapped staked ETH) through the contract. The principal is permanently locked — no function exists to withdraw it directly. Only the yield generated through Aave v3 flows to the agent's Locus payment wallet, where spending guardrails apply. The agent earns its operating budget from yield alone. The capital base is untouchable. **Compliance Gate:** Before any agent can stake, two onchain checks must pass: (1) ERC-3643 Identity Registry check — institutional KYC/AML accountability for the agent's address; (2) ERC-8004 Agent Identity check — the staking address must own a valid onchain agent identity NFT. Both checks run in Solidity. Not a frontend filter. Structurally enforced. **Components:** - Smart contract on Base mainnet: 0x99FCC335f879DbcF3AdA1623A769C7a6B3883d3D — 9/9 Foundry fork tests green - MCP server: 7 natural-language tools (stake, harvest yield, check eligibility, get position, register identity, treasury stats, vault monitor) — Claude Desktop compatible - Monitoring agent: continuous vault health reports in plain English **Status Network (Gasless L2):** Contract deployed gaslessly on Status Network Sepolia Testnet — gasPrice=0, gas=0 throughout. Deploy TX: 0xa98a5362454127061a612bd0f4a68ea8ec3000eb4d5d1f20812fafdb5f63109b. Agent action TX: 0xab3bc74d4fd1485d7f08e48dbbfb183fbedb604d769849b6382d83ad626e9a00. Contract: 0x4Aad344153Cc8b7EF92771671C90820946A8e578 (sepoliascan.status.network). Zero gas fees demonstrate the gasless agent economy in practice — the AI agent deployed and transacted autonomously with no ETH cost at all. **Key addresses (Base mainnet):** ComplianceYieldTreasury 0x99FCC335f879DbcF3AdA1623A769C7a6B3883d3D · wstETH 0xc1CBa3fCea344f92D9239c08C0568f6F2F0ee452 · Aave v3 Pool 0xA238Dd80C259a72e81d7e4664a9801593F98d1c5 · Locus wallet 0xCb99E647AAb7670eb08947126C8525285A965AD7 **Lido tracks:** All three Lido sub-bounties covered — wstETH treasury primitive ($3k), MCP server with 7 Lido-native tools ($5k), and monitoring agent for vault health reporting ($1.5k). **Locus track:** Locus wallet is hardwired at the contract level as the sole yield destination. No agent or owner can redirect yield — it's structurally enforced in Solidity, not a config parameter. **ERC-8004 / Protocol Labs track:** The staking address must own a valid ERC-8004 agent identity NFT (checked in Solidity). Only agents with verifiable onchain identity can use the treasury.
