Description
Live Demo: yield-agent-web.vercel.app
Chain: Arbitrum Sepolia
LionHeart is a Chat-First DeFi Intelligence Platform built on Arbitrum. It pairs every user with OpenClaw — an AI agent that doesn't just answer questions, but proves its competence on-chain.
Think of it as a personal quant analyst that:
🎓 Teaches you DeFi (interactive lessons + quizzes)
🔍 Hunts the best yields across 10+ Arbitrum protocols in real-time
📊 Researches markets with live TVL, APY, and risk-tier analysis
🛡️ Earns your trust through an on-chain reputation score (ERC-8004 NFT)
💼 Executes trades only after reaching reputation ≥ 100 (reputation-gated)
Every piece of data the agent provides is verifiable — SHA-256 hashed, optionally signed and pinned to IPFS. This is not a chatbot; it's a trustless financial advisor.
Problem | LionHeart's Solution |
|---|
DeFi is overwhelming for newcomers | Chat-first UX with an AI tutor |
Yield farming requires constant monitoring | Automated Yield Hunter crawls 800+ pools every 15 min |
No way to verify AI agent advice | On-chain ERC-8004 identity + SHA-256 data stamps |
Agents have no accountability | Reputation scoring — users rate the agent on-chain |
Trading bots are black boxes | Reputation-gated: agent must earn trading permissio |
Progress During Hackathon
Phase 1 — Foundation & Smart Contracts
Status: Deployed
Designed and deployed 4 smart contracts to Arbitrum Sepolia
Contract Address:
IdentityRegistry 0x27558E...1449 ERC-721 + ERC-8004 agent NFT identity
ReputationRegistry 0xDD9a5E...1c83 On-chain feedback & tag-based reputation scoring
YieldManager 0xaE1405...C606 Mock yield strategy for demo
AgentVault 0x7B7324...93e7 Treasury & payment interceptor
Built full Hardhat workspace with end-to-end tests and ignition deployment module using Hardhat and OpenZeppelin.
Solidity version: 0.8.24. Test coverage: 100% (critical modules).
Phase 2 — OpenClaw Agent Engine
Core: Custom Gateway + modular skills
Architected the OpenClaw Gateway — an Express + WebSocket server implementing a Tool Registry pattern. Implemented 9 modular, SOLID-compliant skills:
Skill What it does
Yield Hunter Crawls 800+ pools across Aave, Pendle, Camelot, GMX, and Dolomite via DefiLlama
Market Research Live TVL & protocol analytics for the Arbitrum ecosystem
News Analytics Sentiment & signal extraction via CryptoPanic
Daily Brief Composite morning report (yields + news + risk)
Tutor Mode 8-lesson DeFi curriculum + quizzes (lessons 4–8 = x402 premium)
Trust Stamp SHA-256 hashing + ECDSA signing of market research
Wallet Control Reputation-gated (score ≥ 100) swap/deposit/withdraw execution
Vault Manager AgentVault treasury health monitoring & rebalancing
Register Agent Mints ERC-8004 NFT identity (inline data URI from user profile)
Integrated Google Gemini as the AI backbone with a “Master DeFi” system prompt covering IL formulas, veTokenomics, delta-neutral strategies, flash loans, and 10+ protocols.
Phase 3 — Web Frontend & UX
Experience: Chat-first, action-oriented
Chat-first UI where every interaction flows through the AI agent. Quick actions: Show me yield opportunities, Top Arbitrum protocols, Teach me about DeFi, Today’s brief.
Wallet → NFT minting → reputation badge pipeline with three comm modes: HTTP proxy (prod), WebSocket (real-time), Mock (dev).
Frontend built with Next.js + React and styled using Tailwind CSS. Wallet UX implemented via RainbowKit with web3 stacks Wagmi + Viem.
Phase 4 — Infrastructure & Production Deployment
Live ops & reliability
OpenClaw Gateway deployed to AWS EC2 (public endpoint).
Zero-downtime via PM2; containerized components using Docker.
Frontend hosted on Vercel.
Automated 15-minute crawler job scanning 800+ pools across connectors (Aave, Pendle, Dolomite, GMX, DefiLlama + Camelot).
Persistent storage: Supabase (Postgres).
Technical Architecture (concise)
Data flow (summary):
On-chain events → Yield Crawler (15-min cron) → OpenClaw Gateway (skills router + Gemini AI) → API proxy → Frontend / Wallet UX → Agent actions (reputation gating + on-chain txs).
Key integration points: on-chain contracts (IdentityRegistry, ReputationRegistry, AgentVault), off-chain sources (DefiLlama, CryptoPanic), and Supabase for user/session state.

Key Innovations — Quick bullets to copy
ERC-8004 Agent Identity: NFT agents with verifiable metadata + optional operational wallet — first trustless agent registry on Arbitrum.
Reputation-Gated Trading: Agents require collective rating ≥ 100 before executing user funds.
x402 Payment Protocol: Premium skills behind HTTP 402 micropayment gates (on-chain micropayments support).
Verifiable Data Pipeline: SHA-256 + optional ECDSA signing and IPFS pinning for auditable, tamper-evident market research.
Master DeFi Intelligence: Institutional-grade system prompt encoding protocol mechanics, impermanent loss math, veTokenomics, and neutral/leveraged strategies.
