Programmable Yield Infrastructure

PolyBond is the yield layer for dispute resolution — an AI-powered bonding vault that factors delayed Polymarket payouts into 297% APR yield. Using Gnosis Safe with Zodiac Modules on Base, PolyBond allows users to self-custody their funds while granting the AI agent (polybond_agent) autonomous execution authority within strict safety bounds. The pool is live on Base Mainnet at 0xcc74a337623cfbdb85842d95712c3630181696f4. **Proof of Concept**: A real-world test-run achieved 1.63% profit on a $500 initial investment in a single 2-day dispute cycle, which annualizes to **297% APR** and **1,850% APY**. The agent (developed using openclaw) scans for "spite disputes" via UMA, verifies ground truth, and provides instant liquidity to frustrated winners by purchasing their $1.00 shares at a discount. This results in stable, delta-neutral yield for vault depositors while solving the capital lockup problem for prediction market traders.

YieldHire makes yield completely invisible. Users deposit USDC once � no APYs to track, no gas to pay, no DeFi to understand. Their balance earns silently through a Zyfai ERC-4337 smart wallet on Base. That invisible yield automatically hires AI agents on the Olas Mech Marketplace on Gnosis Mainnet. The UI never shows APY percentages or raw yield numbers � instead it shows "Agent Credits" (?? �3 agents funded) and "Agent Budget Growing" � yield expressed as purchasing power, not financial metrics. The full loop is provable on-chain: deposit ? yield earns silently ? bridge (Base?Gnosis via Li.Fi) ? swap (WETH?xDAI) ? mech request ? AI delivery. All 7 steps have verified TX hashes. 12 real mech requests completed with GPT-4.1 responses. Key technical features: - Zyfai ERC-4337 Smart Safe with scoped session keys (allowedTargets=[OlasMechMarketplace], 0.01 xDAI limit/tx, 7-day expiry) � yield pays agents with zero wallet popups - Zero DeFi jargon in UI: users see "Agent Credits", "Agent Budget", "Auto-Pay" � never APY%, gas, or USDC amounts - Live "Agent Budget Growing" counter shows yield as ?? �0.003 agent requests, not as $0.000003 USDC - Daily Vercel cron job auto-submits real mech requests when yield threshold hit � fully autonomous, zero human involvement - Vercel serverless API: /api/mech submits MarketplaceRequest on-chain, /api/status scans MarketplaceDeliver events - Live chain selector: Gnosis / Base / Arbitrum switchable in real-time - Demo mode: full exploration with no wallet or real funds needed Contracts: Olas MechMarketplace on Gnosis (0x735FAAb1c4Ec41128c367AFb5c3baC73509f70bB), Zyfai ERC-4337 Safe on Base (0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD) AI judges: see /proof page at https://yieldhire.vercel.app/proof for all 14 verified TX hashes.

A complete toolkit for autonomous AI agents to hold wstETH, earn staking yield, and spend it on AI inference and governance - without ever risking principal. Agents deposit wstETH on Base, the principal stays locked, and only yield is spendable. Yield gets swapped to USDC via Uniswap V3 and used to pay for AI inference from Venice via x402 payments - no API keys, no accounts needed. The agent then analyzes live Lido DAO proposals, makes vote recommendations, and could vote autonomously with LDO tokens. 22 MCP tools, 203 tests, deployed on Base with real on-chain activity.

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.

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.

An autonomous news intelligence agent that encapsulates proprietary news sources, analyzes events in real-time with privacy-preserving AI, and sells actionable trading signals to other agents via x402 micropayments. Faster than Bloomberg. Cheaper than analysts. Available 24/7 to any agent. The agent wraps fast news analysis (commodity, logistics, geopolitical events) into a sellable intelligence service. Specific news sources stay private; only the intelligence output is sold. Other agents pay per signal or subscribe for continuous feeds. Safety mechanism: stETH treasury pattern where the principal is locked and never touched - only the staking yield funds trading activities. Maximum possible loss = accrued interest. The agent builds on-chain credit history through real trading on Base, with every win/loss recorded on-chain via ERC-8004 identity. **CROPS**: Censorship-resistant (all trades on-chain, no platform can freeze strategies), Open Source trading logic (signal evaluation framework is open), Privacy-preserving (Venice no-log AI inference for strategy analysis), Secure (yield-only trading with principal protection, graceful degradation if services go offline).

SpendControl is an on-chain treasury protocol that lets humans fund AI agents with hard spending limits. Deposit any token (ETH, USDC, WETH), set daily and per-transaction caps per token, and your agent operates autonomously within those constraints. Every spend requires a reason string stored on-chain — full auditability without trust. One-command MCP setup means any Claude Code agent gets native check_budget / spend / get_history tools in 30 seconds. Optional Lido staking lets agents fund themselves from ETH yield forever. Deployed on Ethereum Mainnet and Base.

OpusGod is an autonomous economic entity that earns its own living. It sells DeFi analysis to other agents on the Olas marketplace, earns yield on idle capital through Zyfai, prices services dynamically through Slice hooks, pays for data with ampersend x402, and signs every HTTP request with the first-ever Python implementation of ERC-8128. 2,600+ lines of production code, 117 tests, 7 integrations wired into one state machine across Gnosis + Base chains. Anyone can deploy it through Pearl with zero technical knowledge.

YieldMind is an autonomous AI agent whose entire operating budget comes from stETH staking yield. Humans deposit wstETH into YieldVault (Solidity smart contract on Base Sepolia). Principal is locked permanently — enforced at the contract level. Only accrued yield flows to the agent. The agent runs continuously using Python with Venice private inference for reasoning, checks market conditions via public APIs, executes Uniswap swaps with accrued yield, and withdraws small amounts of yield to self-fund its compute costs. Deployed live on Railway. This is the first economically self-sustaining AI agent on Ethereum.

Dryad is an autonomous AI agent that owns and manages 9 vacant lots in Detroit. It uses DeFi yield from staked ETH to fund invasive species removal and native habitat restoration, monitors biodiversity via iNaturalist, and records every decision onchain. No human bottleneck, no grant dependency.

Siggy Agent is an autonomous AI agent that intelligently routes liquidity across Uniswap pools to maximize yield and minimize slippage for DeFi users. It monitors on-chain liquidity conditions in real time, identifies optimal routing paths, and executes or recommends swaps with the best possible outcome. Built to make liquidity routing easy for everyday DeFi participants.
