YieldAgent — Autonomous AI Liquidity Manager on X Layer

Live Demo: frontend-nine-theta-22.vercel.app | GitHub: github.com/dddd86971-cloud/yield-agent

Built for OKX Build X AI Hackathon — Season 2, X Layer Arena Track.

📖 Project Introduction

YieldAgent is an autonomous AI liquidity strategist that manages Uniswap V3 concentrated-liquidity positions on X Layer. A user describes their intent in one sentence; the AI parses it, runs three parallel analysis brains (Market · Pool · Risk), deploys a real V3 LP position via the OnchainOS Agentic Wallet TEE, and continuously monitors / rebalances / compounds — all without human intervention, with every reasoning step permanently anchored on-chain.

Core Value Proposition:

One-sentence deploy: "Deploy 100 USDT as LP, conservative" → real V3 NFT minted on X Layer
Three-Brain AI: Market + Pool + Risk brains evaluate every 5 minutes
TEE-signed execution: All DEX transactions signed inside OnchainOS Agentic Wallet (ERC-4337)
On-chain audit trail: Every AI decision (including "do nothing") is recorded on-chain via DecisionLogger
Copy-trading: FollowVault lets anyone mirror agent strategies with one click
Per-wallet PnL tracking: Historical value + fees curves scoped to each connected browser wallet
Cross-protocol yield aggregator: Live opportunities via OnchainOS defi search across every X Layer DEX
Restart-survival persistence: File-based JSON snapshots for strategies, history, and PnL points (no SQLite native-dep headaches)
Proactive AI chat: PnL / Position / History / Suggest quick-commands generate grounded recommendations on demand

What makes YieldAgent different: Unlike chatbot wrappers that only suggest trades, YieldAgent is a fully autonomous agent that plans, executes, monitors, rebalances, and compounds real on-chain positions — with every reasoning step permanently anchored on-chain for verifiability, and every snapshot recoverable across restarts.

✨ Latest Build Highlights

This build pushed the project past the v1 demo into a production-ready feature set. What landed in the latest round:

Area	Delta
Persistence	New `PersistenceService` — debounced JSON writes to `data/strategies.json`, `data/history.json`, `data/pnl-snapshots.json`. Full restart survival; no native deps.
Multi-tenant state	`AgentCoordinator.getStateForWallet(address)` + per-wallet WebSocket filtering. Every browser wallet sees only its own strategy.
PnL tracking	New `/app/pnl` dashboard with pure-SVG dual-axis chart (position value + fees). `capturePnLSnapshot()` writes on every full evaluation.
Pool catalogue	New `/app/pools` page — live on-chain state for every supported pool + cross-protocol opportunities from OnchainOS `defi search`.
Proactive AI chat	Quick-command handlers for `pnl` / `position` / `history` / `suggest` (EN + 中文). `getProactiveSuggestion()` generates grounded recommendations.
Richer system prompt	`buildChatSystemPrompt()` replaces `JSON.stringify(state)` dumps with a tight context block (strategy, market, pool, risk, PnL, quick-command hints).
CLI footprint reduction	Generic TTL read-cache in `OnchainOSAdapter` (LRU-bounded at 128 entries). Cuts subprocess spawn count by ~90% under frontend polling load.
New REST endpoints	`/api/strategies`, `/api/pnl/:strategyId`, `/api/pnl`, `/api/pnl/refresh`, `/api/defi/opportunities` — all wallet-scoped where relevant.
Fix: WETH/USDT typo	Corrected `fB` → `fC` in 5th byte of WETH/USDT pool address across backend config.
Fix: IntentInput dead UI	Removed misleading pool selector whose state was never propagated.

🚀 v3 Roadmap — Multi-Brain x402 Economy (Next Sprint)

Inspired by the Build X AI Season 2 winners — Helios (Most Active Agent, multi-agent x402 economy) and XSight (Best x402 Implementation, API-as-revenue) — v3 turns YieldAgent from "automated LP" into "an agent economy that pays its own ops".

Upgrade	Status	What Changes
x402 micropayments	📐 Designed	Coordinator pays each Brain ~0.0001 USDG per call via EIP-3009. After seed funding, the economy is self-sustaining.
Brain-per-wallet	📐 Designed	Each Brain (Market / Pool / Risk / Lending) gets its own sovereign TEE wallet. Coordinator becomes the orchestrator routing payments.
Aave V3 Lending Brain	📐 Designed	New 4th brain — idle USDT auto-supplies to Aave V3 for baseline yield while LP cycles complete.
All 14 OnchainOS skills	🚧 In Progress	Currently using 6/14. Adding `defi-invest`, `defi-portfolio`, `dex-signal`, `dex-token`, `security`, `audit-log`, `onchain-gateway`, `dex-ws`.
Stdio MCP server	📐 Designed	Expose deploy / analyze / status / pnl as MCP tools so Claude Code / Cursor / Claude Desktop can plug in directly.
Explicit FSM + 4 hard circuit breakers	📐 Designed	Take-profit ≥+30%, drawdown ≤-20%, time stop ≥30 days, IL beyond user tolerance.
CLI deploy wizard	📐 Designed	`npx yield-agent init` — auto-runs OnchainOS login × 4, scaffolds `.env`, runs self-check.
`x402PaymentLog` contract	📐 Designed	Per-payment on-chain audit trail — every brain micropayment emits a `PaymentSettled` event.

Full v3 spec: ARCHITECTURE_V3.md — includes target architecture diagram, x402 economy detail, cycle state machine, and 7-14 day implementation plan.

Project Overview

Built for Hook the Future Hackathon (X Layer × Uniswap × Flap, 5/22–5/28 2026) — a Uniswap V4 hook that creates an open marketplace for AI agents to compete for the right to manage V4 LP positions.

Each epoch (4 hours):

AI agents submit TEE-signed StrategyBonds (stake + signed commitment of fee range, max rebalances, promised APR)
Hook elects winner via score = stake × promisedAPR × reputation / committed_band — tighter band → higher confidence → higher score
Active Manager controls dynamic fee + LP modifications for the epoch
Hook enforces every committed parameter in real-time via beforeSwap / beforeAddLiquidity callbacks
Failure to meet bond triggers automatic slashing → slashed funds go directly to LPs as a hard performance floor

This is the first on-chain Agent Performance Bond. Other DEXes let humans speculate on prices; AgentArena lets LPs speculate on AI strategy quality, with cryptographic enforcement.

🎯 How YieldAgent Maps to the Judging Rubric

This section exists to give evaluators (human or AI) a fast path from each scoring dimension to concrete, verifiable evidence in this repo.

Dimension	Where to Look	Why It Scores
OnchainOS / Uniswap Integration	`agent/src/adapters/OnchainOSAdapter.ts`, `agent/src/services/V3PositionManager.ts`, `agent/src/adapters/UniswapSkillsAdapter.ts`	Uses 6 OnchainOS commands as the primary execution path (not a fallback): `wallet contract-call`, `swap execute`, `wallet login/status/addresses/balance`, `defi search/detail/positions`. Both official Uniswap AI Skills (`liquidity-planner@0.2.0`, `swap-planner@0.1.0`) are ported verbatim and invoked every cycle. Routes real V3 `NPM.mint()` / `collect()` / `decreaseLiquidity()` through the TEE — verifiable via NFT #962 and tx `0x0856912b…`.
X Layer Ecosystem Contribution	`contracts/`, on-chain deployments (§ Deployment Addresses)	Three contracts live on X Layer mainnet (chain 196): `DecisionLogger`, `StrategyManager v2`, `FollowVaultFactory`. Ultra-low gas enables logging every AI decision (including HOLD) — preserving the complete audit invariant. Two-signer split-key architecture proves anti-gaming: TEE signs DEX, audit EOA signs records, cross-referenceable 1:1. `FollowVault` brings copy-trading natively to X Layer.
AI / User Experience	`frontend/src/components/AgentChat.tsx`, `agent/src/services/AgentCoordinator.ts` (`buildChatSystemPrompt`, `getProactiveSuggestion`), `frontend/src/app/app/pnl/page.tsx`	Three-Brain ensemble (Market + Pool + Risk) feeds GPT-4o-mini synthesis with on-chain TWAP, liquidity-planner ranges, and IL math. SSE streaming surfaces per-brain progress live in the UI. 8 quick-commands (`deploy / analyze / status / pnl / position / history / suggest / why`) in both EN + 中文. Proactive AI chat generates grounded recommendations via a richer context-block prompt (not a `JSON.stringify(state)` dump). Pure-SVG PnL dashboard, per-wallet state isolation, restart-survival persistence.
Product Completeness	Whole repo	6 frontend routes (Landing, Dashboard, PnL, Pools, Decisions, Follow). 19 REST + SSE + WebSocket endpoints. 85 automated tests (68 Hardhat unit + 17 Playwright E2E). Full lifecycle proven on mainnet: deploy → mint → monitor → rebalance → compound → audit. Multi-tenant wallet-scoped state. Cross-protocol yield aggregator. JSON-based persistence with debounced writes. Live demo + verified tx hashes + end-to-end documentation.

Key Differentiators (for at-a-glance scoring):

Real V3 LP lifecycle, not just swaps — NPM.mint(), collect(), decreaseLiquidity(), full rebalance, fee compounding — all signed by TEE.
Split-key anti-gaming proof — TEE signer physically cannot fabricate DEX transactions; audit records must match on-chain reality 1:1.
Every decision is an on-chain event — including HOLD, preserving a tamper-proof AI reasoning trail.
Both Uniswap AI Skills ported verbatim — not "inspired by", the actual methodology from the Uniswap AI repo.
Multi-tenant ready today — per-wallet state, per-wallet WebSocket filtering, per-wallet PnL curves.
OpenAI-optional — the three-brain snapshot endpoint works without any LLM; deterministic fallbacks everywhere.

Two-Signer Anti-Gaming Architecture

Signer	Address	Responsibility	Cannot Do
OnchainOS Agentic Wallet (TEE)	`0x6ab27b82890bc85cd996f518173487ece9811d61`	All DEX txs: V3 mint, swap, approve, rebalance	Cannot write to audit contracts
Audit EOA	`0x2E2FC9d6daf5044F53412eb49dF5e82a9cFB3838`	Audit records: deployStrategy, logDecision	Cannot sign DEX transactions

This split-key design means a judge can cross-reference StrategyManager.getExecutions(strategyId) against the Agentic Wallet's on-chain activity — the tx hashes must match 1:1, because the audit signer physically cannot fabricate DEX transactions.

Wallet Roles: Who Does What

YieldAgent uses three distinct wallets, each with a clear responsibility:

Wallet	Role	What It Does	What It Cannot Do
Agentic Wallet (TEE) `0x6ab27b82...`	Executor	Signs all DEX txs: V3 mint, swap, approve, collect fees, rebalance	Cannot write audit records
Audit EOA `0x2E2FC9...`	Recorder	Writes strategy records + decision logs to on-chain contracts	Cannot sign DEX transactions
User's Browser Wallet	Observer	Identity binding — records "who initiated this strategy" in the frontend	Does not sign any transaction, does not spend any funds

The user's browser wallet connects via RainbowKit/wagmi but never signs transactions or spends tokens. All on-chain execution is handled by the Agentic Wallet inside the OnchainOS TEE.

Current Architecture: Single-Agent Demo

The hackathon demo runs a single Agentic Wallet that manages all LP positions. This proves the core capability: an AI agent that autonomously deploys, monitors, rebalances, and compounds real V3 LP positions via TEE-signed transactions, with every decision permanently recorded on-chain.

Production Roadmap: Per-User Isolated Agents

The architecture is designed to scale from single-agent to full multi-tenant without code changes:

Phase 1 — Self-Hosted Agent (Available Now)

Any user can run their own isolated agent instance today:

Create your Agentic Wallet: onchainos wallet login --force
Get API keys from OnchainOS Dev Portal
Clone this repo, fill .env with your own keys
Fund your Agentic Wallet with USDT + OKB on X Layer
Run cd agent && npm start — your LP positions belong to your wallet

Each instance is fully self-contained. Zero code changes required.

🔧 OnchainOS & Uniswap Skill Usage

OnchainOS Core Modules Used

YieldAgent deeply integrates 6 OnchainOS core commands as the primary execution layer. All DEX transactions are routed through the Agentic Wallet TEE — the agent's local private key never signs DEX operations.

OnchainOS Command	Where Used	Purpose
`onchainos wallet contract-call`	`V3PositionManager.mintViaTEE()`, `collectViaTEE()`, `decreaseLiquidityViaTEE()`	Primary execution path — routes encoded calldata (V3 mint, approve, collect) through TEE signer
`onchainos swap execute`	`AgentCoordinator.rebalanceViaOnchainOS()`	DEX swap via OKX aggregator for token rebalancing
`onchainos wallet login/status`	`OnchainOSAdapter.checkWalletStatus()`	Agentic Wallet authentication and health check
`onchainos wallet addresses`	`OnchainOSAdapter.getAddresses()`	Retrieve TEE wallet addresses
`onchainos wallet balance`	`OnchainOSAdapter.getBalance()`	Query wallet balances on X Layer (chain 196)
`onchainos defi search/detail/positions`	`OnchainOSAdapter.defiSearch()`, `defiDetail()`	Pool discovery, position tracking, market data

Implementation: agent/src/adapters/OnchainOSAdapter.ts — wraps OnchainOS CLI as a spawned subprocess with structured JSON parsing.

Three-tier execution priority (code: AgentCoordinator.ts):

Priority 1: OnchainOS TEE → wallet contract-call → NPM.mint()    ← anti-gaming ✅
Priority 2: Direct PRIVATE_KEY → NPM.mint()                       ← fallback
Priority 3: OnchainOS swap execute                                 ← legacy swap path

Uniswap AI Skills Used

Both official Uniswap AI Skills are ported verbatim into the agent and invoked on every deploy/rebalance cycle:

Skill	Version	Source	Where Called	Function
liquidity-planner	`0.2.0`	Uniswap AI GitHub	`PoolBrain.analyze()` → `UniswapSkillsAdapter.computeRangeCandidates()`	Pair classification (stable/correlated/major/volatile), tick-spacing table, range width recommendations, TVL assessment
swap-planner	`0.1.0`	Uniswap AI GitHub	`AgentCoordinator.rebalanceViaOnchainOS()` → `UniswapSkillsAdapter.planRebalanceSwap()`	Slippage ladder by pair type, price-impact k-factor estimation, minimum output calculation, split-swap for large orders

Implementation: agent/src/adapters/UniswapSkillsAdapter.ts — runtime-callable port with methodology citation for every output.

Key integration points:

classifyPairType() — categorizes token pairs (stablecoin ±0.5%, major ±5-15%, volatile ±30-100%)
computeRangeCandidates() — generates optimal tick ranges for V3 LP positions
planRebalanceSwap() — calculates slippage tolerance and split-swap strategy for rebalancing

Real V3 LP Lifecycle (Not Just Swaps)

V3 Operation	Method	Signed By	Code
Mint LP position	`NPM.mint()` via TEE	Agentic Wallet	`V3PositionManager.mintViaTEE()`
Collect trading fees	`NPM.collect()` via TEE	Agentic Wallet	`V3PositionManager.collectViaTEE()`
Remove liquidity	`NPM.decreaseLiquidity()` via TEE	Agentic Wallet	`V3PositionManager.decreaseLiquidityViaTEE()`
Full rebalance	remove → collect → re-mint	Agentic Wallet	`V3PositionManager.rebalance()`
Optimal token split	sqrtPrice-based ratio	Local compute	`V3PositionManager.calculateOptimalAmounts()`

⚙️ Operating Mechanism

End-to-End Strategy Lifecycle

1. User Input
   "Deploy 100 USDT as LP in OKB pool, conservative"
                    ↓
2. IntentParser (GPT-4o-mini)
   → { principal: 100, riskProfile: "conservative", preferredPairs: ["USDT/OKB"] }
                    ↓
3. Three-Brain Parallel Analysis
   ┌─────────────┐  ┌─────────────┐  ┌─────────────┐
   │ Market Brain │  │  Pool Brain  │  │  Risk Brain  │
   │ On-chain TWAP│  │ liquidity-   │  │ IL math,     │
   │ volatility,  │  │ planner      │  │ health 0-100 │
   │ trend state  │  │ range recs   │  │ rebalance    │
   └──────┬───────┘  └──────┬───────┘  └──────┬───────┘
          └─────────────────┼─────────────────┘
                            ↓
4. GPT-4o-mini Synthesis
   → Action: DEPLOY | REBALANCE | HOLD | COMPOUND | EMERGENCY_EXIT
   → Reasoning: "Market ranging, vol 0.94%, Pool APR 12.5%, Health 87%"
   → Confidence: 95%
                            ↓
5. Execution (OnchainOS TEE)
   V3PositionManager.deployLPViaTEE()
   → approve USDT → approve WOKB → NPM.mint() → real V3 NFT
                            ↓
6. On-Chain Audit
   StrategyManager.recordExecution(strategyId, txHash)
   DecisionLogger.logDecision(strategyId, reasoning, confidence)
                            ↓
7. Continuous Monitoring
   Every 5 min:   Quick edge-proximity check
   Every 30 min:  Full three-brain re-analysis
   Every 6 hours: Fee collection heartbeat
                            ↓
8. Auto-Rebalance (when triggered)
   decreaseLiquidity → collect → re-mint at new optimal range
   All via TEE, all logged on-chain

The Three Brains

Brain	Data Source	Output	Key Computation
Market Brain	On-chain TWAP, 2016-snapshot price buffer (~7 days)	Volatility, trend state, price momentum	Realised volatility (ATR-style), trend classification (trending_up/down/ranging/high_vol), whale detection
Pool Brain	slot0, liquidity, tick spacing, oracle observations + `liquidity-planner` methodology	Recommended LP ranges, fee APR, IL estimate	Pair classification, tick-spacing snapping, TVL assessment, DexScreener data integration
Risk Brain	Current tick vs entry tick vs range bounds	Health 0-100, IL%, rebalance urgency	Concentrated-liquidity IL formula, edge proximity vs risk-profile threshold, per-profile (conservative/moderate/aggressive) calibration

Agent Roles

YieldAgent runs a single AgentCoordinator process that manages multiple strategies. It is not multi-agent; instead, it uses a three-brain ensemble within one agent:

Component	Role	Type
AgentCoordinator	Orchestrator — runs monitor loop, coordinates brains, executes trades, handles chat quick-commands, captures PnL snapshots, keeps per-wallet state	Core agent process
MarketBrain	Analyzes market conditions (price, volatility, trend)	Analysis module
PoolBrain	Analyzes pool state (liquidity, fees, optimal ranges)	Analysis module
RiskBrain	Assesses position health and rebalance urgency	Analysis module
IntentParser	Converts natural language to structured intent	NLP module
V3PositionManager	Manages real V3 LP positions (mint/collect/rebalance)	Execution module
OnchainOSAdapter	Interfaces with OnchainOS TEE for signed transactions; TTL-cached reads to cut subprocess load	Signing module
PersistenceService	Debounced JSON snapshots for strategies, history, PnL — restart survival with zero native deps	Storage module

🌐 Positioning in X Layer Ecosystem

Why X Layer is Essential for YieldAgent

Gas-free monitoring loop: The agent evaluates positions every 5 minutes and logs every decision on-chain — including HOLD decisions. This generates thousands of transactions per month. Only X Layer's ultra-low gas cost makes this economically viable, enabling a truly transparent AI audit trail.
Native OnchainOS integration: The Agentic Wallet TEE, ERC-4337 account abstraction, and OKX DEX aggregator are all natively available on X Layer. YieldAgent leverages wallet contract-call for V3 LP operations and swap execute for token rebalancing — capabilities that don't exist on other chains.
Official Uniswap V3 deployment: X Layer hosts a fully verified Uniswap V3 deployment (Factory, NPM, Router, Quoter, TickLens). YieldAgent is the first project to route V3 NonfungiblePositionManager calls through OnchainOS TEE on X Layer.
On-chain AI audit trail: Every AI decision — including the reasoning and confidence score — is permanently stored on X Layer via DecisionLogger. The low transaction cost means we never need to drop HOLD logs, preserving the complete audit invariant.

└─────────────────────────────────────────────────────────────────┘

YieldAgent brings autonomous DeFi intelligence to X Layer — users who lack the expertise or time to manage V3 concentrated liquidity can delegate to an AI agent that operates transparently, with every decision verifiable on-chain. The copy-trading system (FollowVault) further democratizes access, allowing anyone to benefit from the agent's strategies by simply depositing USDT.
