# aaveclaw - Aave V3 Lending on Base Sepolia

Interact with Aave V3 lending protocol on Base Sepolia testnet. Manages the full lending lifecycle using the wallet from `~/.x402-config.json`.

## Setup

Run `setup.sh` on first use to install dependencies (ethers v6):

```
bash scripts/setup.sh
```

## Commands

### Check Health Factor

Check the current lending position. Safe to run anytime, read-only.

```
bash scripts/health.sh [address]
```

If no address is provided, uses the configured wallet address.

### Mint Test Tokens (Faucet)

Get testnet WETH or USDC from the Aave faucet. Run this first if the wallet has no tokens.

```
bash scripts/faucet.sh weth 1       # Mint 1 WETH
bash scripts/faucet.sh usdc 1000    # Mint 1000 USDC
```

### Deposit Collateral

Deposit WETH as collateral into Aave. Auto-wraps native ETH to WETH if needed.

```
bash scripts/deposit.sh 0.5         # Deposit 0.5 WETH
```

### Borrow USDC

Borrow USDC against deposited collateral. Uses variable interest rate.

```
bash scripts/borrow.sh 100          # Borrow 100 USDC
```

### Repay Debt

Repay borrowed USDC. Use "max" to repay entire debt.

```
bash scripts/repay.sh 50            # Repay 50 USDC
bash scripts/repay.sh max           # Repay all debt
```

### Withdraw Collateral

Withdraw WETH collateral. Use "max" to withdraw everything (only if no debt).

```
bash scripts/withdraw.sh 0.5        # Withdraw 0.5 WETH
bash scripts/withdraw.sh max        # Withdraw all
```

## Usage Guidelines

- **Always run `health.sh` first** to see the current position before making changes.
- **Ask the user for amounts** before executing deposit, borrow, repay, or withdraw.
- **Always show the health factor** after any state-changing operation (the scripts do this automatically).
- **Warn when health factor drops below 1.5** - the position is at risk of liquidation.
- **Guide new users to the faucet** to get test tokens before depositing.
- **Typical flow**: faucet (get tokens) -> deposit (add collateral) -> borrow (take loan) -> repay (pay back) -> withdraw (retrieve collateral).

## Network Details

- **Network**: Base Sepolia (chain ID 84532)
- **Explorer**: https://sepolia.basescan.org
- **RPC**: https://sepolia.base.org

## Error Handling

- If private key is missing: direct user to create `~/.x402-config.json` with `{"private_key": "0x..."}`
- If insufficient balance: the scripts report exact balances and what is needed
- If health factor would drop too low after borrow: Aave reverts the transaction automatically
- If faucet fails: the faucet contract may have minting limits or may not be available
