AutoFund | Self-Sustaining DeFi Agent

An autonomous agent that earns its own operating budget from DeFi yield, pays for its own LLM inference, provides paid services, and trades via Uniswap -- all without touching locked principal.

The Synthesis Hackathon 2026 — 9 contracts · 3 chains · 19+ onchain TXs · 47 tests passing · 10 MCP tools

The Self-Sustaining Closed Loop

Human Deposits $1,000 → Principal LOCKED → Stake in Lido (3.5% APY) → Yield Accrues → Agent Harvests $50 → Pays $0.003 for 5 LLM Inferences → Provides 3 Paid Services ($1 each) → Earns $3.00 Revenue → Net Profit: $2.997 → Reinvest → Cycle Continues
