LiqX 🛡️

AI-Powered Autonomous DeFi Liquidation Protection

🎯 Executive Summary

LiqX is an autonomous multi-agent system that protects DeFi lending positions from liquidation using real-time monitoring, symbolic AI reasoning (MeTTa), and gasless cross-chain execution via 1inch Fusion+.

Problem: $2.3B lost to liquidations in 2023. Users can't monitor 24/7, gas fees spike during volatility ($100-300/tx), and manual intervention fails during critical moments.

Solution: 4 specialized AI agents working autonomously to monitor, analyze, optimize, and execute position rebalancing before liquidation occurs.

Key Features

✅ Real-Time Monitoring: The Graph subgraph queries Aave V3 positions every 30s on Ethereum Sepolia
🧠 Symbolic AI: MeTTa reasoner evaluates 10+ strategies across protocols/chains for optimal yield + safety
📊 Cross-Chain Optimization: Finds best APY across 5 chains (85% APY found on Kamino Solana vs 5% on Aave)
⚡ Gasless Execution: 1inch Fusion+ Dutch auction = $0 gas fees for users + MEV protection
🌉 Multi-Chain Bridges: Automated Stargate/LayerZero/Wormhole bridging for cross-chain opportunities

🔄 Agent Communication Flow

Step-by-Step Process

1. Position Detection (every 30 seconds)

Position Monitor queries The Graph subgraph
  ↓
GraphQL: { 
  positions(where: {healthFactor_lt: "2.0"}) {
    user, collateral, debt, healthFactor
  }
}
  ↓
3 risky positions found (HF: 1.15, 0.57, 1.45)

2. Risk Assessment

Position Monitor calculates:
  • Current HF = (collateral × price × 0.85) / debt
  • Risk level = critical/high/medium
  • Sends PositionAlert to Yield Optimizer

Message: {
  type: "PositionAlert",
  user: "0xb2c3...",
  health_factor: 1.15,
  collateral: $50,000 USDC,
  debt: $31,500 USDT,
  protocol: "aave-v3",
  chain: "ethereum"
}

3. Strategy Optimization (MeTTa AI Reasoning)

Yield Optimizer receives alert
  ↓
Fetches top 15 yields from DeFi Llama:
  1. Kamino (Solana) SOL: 85.10% APY ✅
  2. Kamino (Solana) SOL: 79.87% APY
  3. Kamino (Solana) SOL: 57.14% APY
  4. Morpho (Base) USDC: 30.79% APY
  5. Morpho (Base) USDC: 26.77% APY
  ...10 more
  ↓
MeTTa Symbolic AI evaluates each:
  • APY improvement (40 points max)
  • Break-even time (30 points max)
  • Urgency match (20 points max)
  • Position size fit (10 points max)
  ↓
MeTTa selects: Kamino Solana SOL (90/100 score)
Reasoning: "Highest APY (85% vs 5%), cross-chain allowed,
           break-even: 1 day, execution cost: $20"
  ↓
Sends OptimizationStrategy to Swap Optimizer

4. Route Calculation

Swap Optimizer receives strategy
  ↓
Calls 1inch Fusion+ SDK:
  • Cross-chain quote: ETH → Solana
  • Token swap quote: USDC → USDT → SOL
  • Bridge method: Wormhole ($15 cost)
  • Total gas estimate: $20.10
  ↓
Creates 5-step execution plan:
  1. Repay $31,500 USDT debt on Aave
  2. Withdraw $50,000 USDC collateral
  3. Swap USDC → USDT (1inch v6)
  4. Bridge USDT to Solana (Wormhole)
  5. Supply to Kamino (new 85% APY position)
  ↓
Sends ExecutionPlan to Cross-Chain Executor

5. Transaction Execution

Cross-Chain Executor receives plan
  ↓
Checks executed_positions set:
  if position_id in executed_positions:
    log("Already executed - skipping")
    return  # Prevents duplicate execution
  ↓
Marks position_id as executing
  ↓
Executes 5 transactions (simulated timing):
  Step 1: Repay debt      (~2s, real: ~15s)
  Step 2: Withdraw        (~2s, real: ~15s)
  Step 3: Swap via 1inch  (~3s, real: ~30s)
  Step 4: Bridge          (~10s, real: 5-10 min)
  Step 5: Supply          (~2s, real: ~15s)
  ↓
Total: ~19 seconds demo | ~12 minutes real
  ↓
Sends ExecutionResult back to Position Monitor

📊 The Graph Subgraph Deep Dive

Why The Graph?

Real-Time Position Tracking: Blockchain data isn't directly queryable at scale. The Graph indexes Aave V3 events into a GraphQL API for fast, complex queries.

Alternative Approaches (Why We Didn't Use Them):

❌ Direct RPC Calls: Too slow (scan millions of blocks), rate-limited, expensive
❌ Centralized DB: Requires trusted indexer, single point of failure
❌ Event Logs Only: Missing historical state, can't calculate health factors
✅ The Graph: Decentralized, fast (<100ms queries), complex filters, real-time updates

Subgraph Architecture

Location: /liq-x/ folder

Schema (schema.graphql):

type Position @entity {
  id: ID!                    # user address + timestamp
  user: User!                # Link to User entity
  collateralAsset: Bytes!    # Token address (e.g., USDC)
  collateralAmount: BigInt!  # Amount in wei
  debtAsset: Bytes!          # Borrowed token address
  debtAmount: BigInt!        # Borrowed amount
  healthFactor: BigDecimal!  # Calculated: (collateral × LT) / debt
  updatedAt: BigInt!         # Last update timestamp
  liquidated: Boolean!       # Liquidation status
}

type User @entity {
  id: ID!                    # User wallet address
  positions: [Position!]!    # All positions for this user
  totalCollateralUSD: BigDecimal!
  totalDebtUSD: BigDecimal!
}

Indexed Events (subgraph.yaml):

dataSources:
  - kind: ethereum/contract
    name: AaveV3Pool
    network: sepolia
    source:
      address: "0x6Ae43d3271ff6888e7Fc43Fd7321a503ff738951" # Aave V3 Pool
      abi: Pool
    mapping:
      kind: ethereum/events
      apiVersion: 0.0.7
      language: wasm/assemblyscript
      entities:
        - Position
        - User
      eventHandlers:
        - event: Supply(address,address,address,uint256,uint16)
          handler: handleSupply
        - event: Borrow(address,address,address,uint256,uint256,uint16)
          handler: handleBorrow
        - event: Withdraw(address,address,address,uint256)
          handler: handleWithdraw
        - event: Repay(address,address,address,uint256,bool)
          handler: handleRepay
        - event: LiquidationCall(...)
          handler: handleLiquidation

Mapping Logic (src/mapping.ts):

export function handleSupply(event: Supply): void {
  let user = getOrCreateUser(event.params.user);
  let position = getOrCreatePosition(event.params.user);
  
  // Update collateral amount
  position.collateralAmount = position.collateralAmount.plus(event.params.amount);
  
  // Recalculate health factor
  let collateralValue = position.collateralAmount.times(getPrice(position.collateralAsset));
  let debtValue = position.debtAmount.times(getPrice(position.debtAsset));
  position.healthFactor = collateralValue.times(LIQUIDATION_THRESHOLD).div(debtValue);
  
  position.save();
  user.save();
}

GraphQL Queries Used

Position Monitor Query (every 30 seconds):

query GetRiskyPositions {
  positions(
    first: 20
    where: { 
      healthFactor_lt: "2.0"   # Critical threshold
      liquidated: false
    }
    orderBy: healthFactor
    orderDirection: asc
  ) {
    id
    user {
      id
    }
    collateralAsset
    collateralAmount
    debtAsset
    debtAmount
    healthFactor
    updatedAt
  }
}

Response Example:

{
  "data": {
    "positions": [
      {
        "id": "0xb2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3",
        "user": { "id": "0xUser123..." },
        "collateralAsset": "0xA0b8...USDC",
        "collateralAmount": "50000000000", // 50k USDC (6 decimals)
        "debtAsset": "0xdAC1...USDT",
        "debtAmount": "31500000000", // 31.5k USDT
        "healthFactor": "1.15",

⚡ 1inch Fusion+ Integration

Why 1inch Fusion+?

Gasless Execution: Users don't pay gas fees - resolvers compete in Dutch auction and pay gas themselves.

MEV Protection: Time-delayed auctions prevent frontrunning and sandwich attacks.

Best Execution: Multiple resolvers bid for your order, ensuring optimal price.

How It Works

Traditional DEX Swap:

User → Pays $20 gas + 0.3% slippage → Swap on Uniswap → Vulnerable to MEV

1inch Fusion+ Flow:

User creates swap intent (no gas payment)
  ↓
Broadcast to resolver network
  ↓
Dutch auction: Price improves over 60-180 seconds
  ↓
Resolver fills order at best price + pays gas
  ↓
User receives tokens (0 gas paid, MEV-protected)

Integration Points

1. Swap Optimizer - Quote Calculation

File: agents/swap_optimizer.py (lines 376-435)

async def _get_1inch_route(self, from_token, to_token, amount):
    """
    1inch Swap API v6.0 for quote calculation
    """
    # Token addresses for Ethereum mainnet
    token_addresses = {
        'USDC': '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48',
        'USDT': '0xdAC17F958D2ee523a2206206994597C13D831ec7',
        'WETH': '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2'
    }
    
    # 1inch API call
    url = f"https://api.1inch.dev/swap/v6.0/1/quote"
    params = {
        'src': token_addresses[from_token],
        'dst': token_addresses[to_token],
        'amount': str(int(amount * 10**18))  # Convert to wei
    }
    headers = {'Authorization': f'Bearer {ONEINCH_API_KEY}'}
    
    response = await session.get(url, headers=headers, params=params)
    data = await response.json()
    
    # Track response for frontend display
    self.oneinch_responses.append({
        'timestamp': int(time.time() * 1000),
        'from_token': from_token,
        'to_token': to_token,
        'input_amount': amount,
        'output_amount': int(data['dstAmount']) / 10**18,
        'route': '1inch_v6',
        'estimated_gas': int(data.get('gas', 150000)),
        'status': 'success'
    })

Why Quote Endpoint (not Swap):

Demo environment uses Sepolia testnet (Fusion+ requires mainnet)
Quote API shows price/route calculation without executing
Real implementation would use Fusion+ SDK for actual swaps

2. Fusion+ SDK - Cross-Chain Bridge

File: fusion_plus_bridge.py (lines 15-85)

from fusion_sdk import FusionSDK, NetworkEnum

sdk = FusionSDK(
    url='https://api.1inch.dev/fusion-plus',
    network=NetworkEnum.ETHEREUM
)

def get_cross_chain_quote(from_chain, to_chain, from_token, to_token, amount):
    """
    Get cross-chain swap quote via Fusion+ SDK
    """
    quote = sdk.get_quote(
        from_chain=from_chain,      # 'ethereum'
        to_chain=to_chain,            # 'solana'
        from_token=from_token,        # 'USDC'
        to_token=to_token,            # 'SOL'
        amount=amount,                # 50000 (USD value)
        wallet_address=user_address
    )
    
    return {
        'bridge_cost': quote.fee,           # ~$15 for ETH→Solana
        'estimated_time': quote.duration,   # ~5-10 minutes
        'route': quote.bridge_protocol      # 'wormhole' or 'stargate'
    }

Multiple 1inch API Calls Explained

Q: Why do we see 2-3 1inch API calls in the demo?

A: The system processes multiple risky positions simultaneously:

Position 1: Compound (6.5789 USDC collateral)
- 1inch quote: USDC → USDT swap
- Shown in frontend: "6.5789 USDC → 12598388 USDT"
Position 2: Aave V3 (5.5258 USDC collateral)
- 1inch quote: USDC → USDT swap
- Shown in frontend: "5.5258 USDC → 12598384 USDT"

This is correct behavior! Each position requires its own swap calculation. The Swap Optimizer calls 1inch API once per position being rebalanced.

Execution Loop Prevention: The Cross-Chain Executor now tracks executed positions and skips duplicates:

# File: agents/cross_chain_executor.py (lines 164-167)
if msg.position_id in self.executed_positions:
    logger.info(f"⏭️  Position {msg.position_id[:10]}... already executed - skipping")
    return

Frontend Display:

1inch Fusion+ API
2 calls  ← Shows total number of positions processed

Call 1: 6.5789 USDC → USDT (Position from Compound)
Call 2: 5.5258 USDC → USDT (Position from Aave V3)

🧠 MeTTa Symbolic AI Reasoning

What is MeTTa?

MeTTa (Meta Type Talk) is a symbolic reasoning language that performs logical inference, not just pattern matching like neural networks.

Traditional AI (GPT, BERT):

Input: "Find best yield for USDC"
Neural Net: [Pattern matching based on training data]
Output: "Aave usually has good yields" ← Probabilistic, not guaranteed

Symbolic AI (MeTTa):

Input: Position(protocol=aave, apy=5%, hf=1.15, urgency=high)
       AvailableStrategies([kamino:85%, morpho:30%, compound:12%])

Reasoning Logic:
  Rule 1: IF urgency=high THEN prioritize_quick_break_even (20 pts)
  Rule 2: APY improvement = (target - current) / current * 40 pts
  Rule 3: IF execution_cost > daily_yield × 365 THEN reject
  Rule 4: IF cross_chain THEN add_bridge_cost_to_calculation

Evaluation:
  kamino: (85-5)/5 × 40 = 640% × 40 = 40pts + 20pts urgency = 90/100 ✅
  morpho: (30-5)/5 × 40 = 200% × 40 = 32pts + 20pts urgency = 72/100
  compound: Rejected (APY improvement < 10% threshold)

Output: kamino (score: 90, confidence: 90%, reasoning: "Highest APY with acceptable break-even")

Implementation

🛠️ Technology Stack

Backend (Agents)

Fetch.ai uAgents: Autonomous agent framework
Python 3.10+: Agent runtime
aiohttp: Async HTTP client for APIs
loguru: Structured logging

Data Sources

The Graph: Blockchain indexing (Aave V3 events)
DeFi Llama: 95+ protocol APY data
CoinGecko: Real-time token prices
1inch API: Swap routes and gas estimates

Frontend

Next.js 15: React framework with App Router
TypeScript: Type-safe development
Tailwind CSS: Utility-first styling
SWR: Real-time data fetching
Recharts: Data visualization

Smart Contracts (Read-Only)

Aave V3 Pool: Ethereum Sepolia (0x6Ae43...738951)
Subgraph: Custom indexer for position tracking

🔐 Security Considerations

Demo vs Production

Current Demo (Sepolia Testnet):

Simulated transactions (no real funds)
Hardcoded wallet addresses for testing
1inch API quotes only (not actual swaps)
No private key management required

Production Requirements:

Secure Key Storage: Hardware wallets, HSMs, or MPC
Multi-Sig Wallets: Require 2/3 signatures for execution
Transaction Simulation: Pre-flight checks before execution
Rate Limiting: Prevent spam attacks on agents
Oracle Security: Multiple price feeds with deviation checks
Slippage Protection: Max 1-2% slippage tolerance
Gas Price Limits: Reject txs if gas > threshold
Audit: Smart contract and agent code security review

Known Limitations

Testnet Only: Not audited for mainnet deployment
Centralized Agents: Single points of failure (should be distributed)
No Access Control: Anyone can trigger agents (needs authentication)
Simulation Mode: Execution timing is accelerated for demo
