  • Purpose: Wraps AAVE with credit-based rate boosts
  • Configuration:
    • AAVE Pool: 0x6Cbb4e8eC402E07fDF0C8c726a2328134F921F68 (Arbitrum Sepolia)
    • Base APY: 4% (400 bps)
    • Boost 750+: 0.5% (50 bps)
    • Boost 650-749: 0.2% (20 bps)

3. CreditRouter.sol

  • Purpose: Main user-facing contract
  • Features:
    • User registration
    • Credit score integration
    • Transaction routing
    • Yield boost calculations

🧪 Test Suite

Comprehensive Tests Created:

  • ✅ CreditScoreOracleComprehensive.ts - Oracle tests
  • ✅ AAVEAdapterComprehensive.ts - Adapter tests
  • ✅ CreditRouterComprehensive.ts - Router tests
  • ✅ All tests compile successfully

Test Coverage:

  • Deployment verification
  • Credit score validation (300-850 range)
  • APY calculations with credit boosts
  • Supply/borrow/withdraw/repay operations
  • User registration flows
  • Access control checks
  • Edge case handling

🚀 Deployment Options

Option 1: Using Hardhat Ignition (Recommended)

File: ignition/modules/DeployScoreFi.ts

cd aave-middleware-contracts
npx hardhat ignition deploy ignition/modules/DeployScoreFi.ts --network arbitrumSepolia

Requirements:

  • Valid Arbitrum Sepolia RPC URL
  • Account with testnet ETH
  • Updated .env file with:
    • ARBITRUM_SEPOLIA_RPC_URL=your_rpc_url
    • PRIVATE_KEY=your_private_key

Option 2: Manual Deployment Scripts

Files Created:

  • scripts/deploy-simple.ts - Simplified deployment
  • scripts/deploy-all.ts - Full deployment with configuration
  • scripts/deploy-oracle-arbitrum-sepolia.ts
  • scripts/deploy-adapter-arbitrum-sepolia.ts
  • scripts/deploy-router-arbitrum-sepolia.ts

Deployment Order:

  1. Deploy CreditScoreOracle
  2. Deploy AAVEAdapter (with oracle address)
  3. Deploy CreditRouter (with oracle address)
  4. Register AAVE adapter in router

🎨 Frontend Ready

Status: ✅ Complete

Location: /defi-credit-frontend

Features:

  • AAVE-like layout with credit score display
  • Circular gauge for credit score visualization
  • Rating badges (Excellent/Good/Fair/Poor)
  • Boosted APY display showing 4.0% → 4.5%
  • Credit benefits banner
  • Market listings with enhanced rates
  • Proper navbar spacing

To Run:

cd defi-credit-frontend
npm install --legacy-peer-deps
npm run dev

📋 Deployment Checklist

Before Deploying:

  • Get Arbitrum Sepolia testnet ETH from faucet
  • Set up valid Arbitrum Sepolia RPC URL
  • Update .env in aave-middleware-contracts/
  • Create Chainlink Functions subscription
  • Fund subscription with LINK

During Deployment:

  • Compile contracts: npm run compile
  • Deploy using Ignition or manual scripts
  • Save contract addresses
  • Verify contracts on Arbiscan

After Deployment:

  • Add oracle as consumer in Chainlink subscription
  • Update frontend .env with contract addresses
  • Start backend API (npm start in cred-score)
  • Test full flow on frontend

📊 Expected Deployment Output

When deployment succeeds, you'll see:

🎉 DEPLOYMENT COMPLETE!

📋 CONTRACT ADDRESSES:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📍 CreditScoreOracle: 0x...
📍 AAVEAdapter: 0x...
📍 CreditRouter (Main Contract): 0x...
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📝 Add to your .env file:

ORACLE_ADDRESS=0x...
ADAPTER_ADDRESS=0x...
ROUTER_ADDRESS=0x...

🎯 Next Steps

  1. Get Testnet ETH: Visit Arbitrum Sepolia faucet
  2. Set up RPC: Get valid Arbitrum Sepolia RPC from Alchemy/Infura
  3. Deploy: Run deployment command
  4. Save Addresses: Copy all three contract addresses
  5. Configure Frontend: Update .env with addresses
  6. Test: Start API and frontend, test complete flow

🐛 Troubleshooting

Issue: Rate limit on free RPC

Solution: Get your own RPC URL from Alchemy or Infura

Issue: Deployment script import errors

Solution: Use Hardhat Ignition instead (DeployScoreFi.ts)

Issue: Insufficient ETH for gas

Solution: Get more testnet ETH from faucets

Issue: Chainlink Functions errors

Solution: Ensure subscription is funded and oracle is added as consumer

📚 Documentation

  • Deployment Guide: aave-middleware-contracts/DEPLOYMENT.md
  • Contract Addresses: Will be in console output
  • Configuration: .env files in each project folder

✅ What's Complete

  • All contracts written and compiled
  • Comprehensive test suite
  • Deployment scripts (Ignition + manual)
  • Network configuration
  • Frontend with AAVE-like UI
  • API integration setup
  • Documentation

Everything is ready! Just needs a valid RPC URL and testnet ETH to deploy.
