Problem Statement

AI agents need a recurring budget to operate. Today that means manually topping up a wallet every time an agent runs. This friction kills automation � users have to babysit their agents. YieldHire solves this with a self-funding loop: the agent operating budget is continuously earned from yield on the user's stablecoin deposit. Capital works passively while agents work autonomously. No top-ups. No approvals. No interruptions. The yield IS the budget.

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.
