Chainlink Automation Setup

Prerequisites

The contract must be deployed and funded with LINK tokens
You'll need the contract address and owner private key

1. Fund the Contract with LINK

# Load environment variables
source .env

# Fund the contract with 10 LINK (18 decimals)
cast send $LINK_TOKEN \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY \
  "transfer(address,uint256)" \
  0xaFf8c2337df3A7ce17525E6aa1BABCbb926F1421 \
  10000000000000000000  # 10 LINK

# Verify LINK balance
cast call $LINK_TOKEN \
  --rpc-url $RPC_URL \
  "balanceOf(address)" \
  0xcDe14d966e546D70F9B0b646c203cFC1BdC2a961

2. Register with Chainlink Keepers

# Load environment variables
source .env

# Approve Keeper Registry to spend LINK
export KEEPER_REGISTRY=0xE16Df59B403e9B01F5f28a3b09a4e71c9F3509dF

cast send $LINK_TOKEN \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY \
  "approve(address,uint256)" \
  $KEEPER_REGISTRY \
  1000000000000000000  # 1 LINK

# Register with Chainlink Keepers
forge script script/RegisterWithKeepers.s.sol \
  --rpc-url $RPC_URL \
  --broadcast \
  -vvvv

3. Verify Keeper Registration

# Check if the contract is registered
cast call $KEEPER_REGISTRY \
  --rpc-url $RPC_URL \
  "getUpkeepCount()"

# Check the registered upkeep (replace 0 with your upkeep ID if known)
cast call $KEEPER_REGISTRY \
  --rpc-url $RPC_URL \
  "getUpkeep(uint256)" \
  0

4. Test Keeper Automation

Deposit funds to trigger position monitoring
Simulate price movement to test rebalancing
Verify Keeper execution in Tenderly dashboard

Example registration parameters:

Name: AaveAutopilot Keeper
Gas Limit: 500,000
Trigger Type: Custom Logic
Check Data: Encoded user address (or empty for all users)
Gas Lane: 500 gwei
Amount: 5 LINK

Security

Audits

This code has not been audited. Use at your own risk.

Security Features

Reentrancy protection with OpenZeppelin's ReentrancyGuard
Role-based access control
Pausable functionality for emergency stops
Input validation
Secure token handling with OpenZeppelin's SafeERC20

Known Limitations

The keeper may not be able to rebalance if gas prices are extremely high
The contract doesn't handle all edge cases of Aave v3's complex liquidation mechanics
The keeper may need to be topped up with ETH for gas costs

📖 Overview

The AAVE Autopilot Vault provides a simple interface for users to deposit USDC, which is then automatically supplied to AAVE v3 to earn yield. The vault actively manages the health factor of the position and automatically rebalances when necessary to prevent liquidations, providing a hands-off DeFi experience.

✨ Key Features

Automated Health Factor Management: Continuously monitors and maintains optimal health factor (target: 1.5x, minimum: 1.05x)
Chainlink Price Feeds: Uses real-time ETH/USD price data for accurate collateral valuation
Chainlink Keepers Integration: Automated rebalancing when health factor falls below threshold (1.1x)
Gas Optimization: Optimized for network's gas efficiency with minimal external calls
Test Coverage: 85%+
Audit Status: Pending
Mainnet Readiness: Under Review

🔄 Workflow

Deposit Flow

User approves USDC spending by the vault
User deposits USDC into the vault
Vault supplies USDC to AAVE v3
Vault receives aUSDC tokens in return
User receives vault shares representing their deposit

Withdrawal Flow

User requests withdrawal of USDC
Vault calculates the share of aUSDC to redeem
Vault withdraws USDC from AAVE v3
USDC is transferred to the user's wallet
User's vault shares are burned

Rebalancing Flow (Automated)

Chainlink Keeper calls checkUpkeep() at regular intervals
If health factor < threshold, performUpkeep() is triggered
Vault automatically repays debt or adjusts collateral to maintain target health factor
Transaction is submitted by the Keeper network

Troubleshooting

Common Issues

Insufficient Gas:
- Ensure you have enough Sepolia ETH for gas fees
- Get test ETH from a Sepolia faucet
Transaction Reverted:
- Check the error message in the transaction receipt
- Verify token approvals and balances
- Ensure you're using the correct contract addresses
Keeper Not Triggering:
- Check if the contract has enough LINK
- Verify the upkeep is registered on Chainlink Keepers App
- Ensure checkUpkeep returns true
