Interaction Guidelines

Swap Operations

When helping users swap tokens:

1. Get Quote First: Always fetch a quote before executing swaps
2. Check Slippage: Warn if slippage exceeds 1% for stablecoins or 3% for volatile pairs
3. Gas Estimation: Include gas cost in USD for cost-benefit analysis
4. MEV Protection: Recommend private RPC endpoints for large swaps

## Swap Analysis

**Route**: USDC → WETH → TARGET_TOKEN
**Input**: 1,000 USDC
**Output**: ~X.XX TARGET (estimated)
**Price Impact**: X.XX%
**Gas Estimate**: ~$X.XX
**Slippage Tolerance**: X%

**Recommendation**: [Execute/Wait for better price/Split order]

Lending Operations

When helping users with lending protocols:

1. Health Factor: Always check health factor before and after operations
2. Liquidation Risk: Calculate liquidation price for borrowed positions
3. APY Comparison: Compare rates across protocols
4. E-Mode: Suggest efficiency mode for correlated asset pairs

## Position Analysis

**Protocol**: Aave V3
**Chain**: Ethereum

### Supplied Assets
| Asset | Amount | Value | APY |
|-------|--------|-------|-----|
| ETH   | 10.00  | $XX,XXX | X.XX% |

### Borrowed Assets
| Asset | Amount | Value | APY |
|-------|--------|-------|-----|
| USDC  | 5,000  | $5,000 | X.XX% |

**Health Factor**: X.XX
**Liquidation Price**: ETH @ $X,XXX
**Net APY**: X.XX%

Yield Strategy Analysis

When analyzing yield opportunities:

1. Risk Assessment: Evaluate smart contract risk, impermanent loss, protocol risk
2. APY Breakdown: Separate base APY from reward token emissions
3. Sustainability: Assess if yields are sustainable long-term
4. Capital Efficiency: Compare yield per unit of risk

## Yield Opportunity

**Protocol**: Curve + Convex
**Pool**: 3pool (DAI/USDC/USDT)

**Base APY**: X.XX%
**CRV Rewards**: X.XX%
**CVX Rewards**: X.XX%
**Total APY**: X.XX%

**Risks**:
- Smart Contract Risk: Low (audited, battle-tested)
- Impermanent Loss: Minimal (stablecoin pool)
- Protocol Risk: Low (established protocols)

**Recommendation**: [Suitable for/Not recommended for] [risk profile]

Best Practices

1. Always Simulate First: Use eth_call or Tenderly to simulate transactions
2. Check Allowances: Verify token approvals before swaps/deposits
3. Monitor Gas: Wait for low gas periods for non-urgent transactions
4. Diversify: Don't concentrate all assets in one protocol
5. Stay Updated: Check protocol governance for parameter changes

Security Warnings

• Never share private keys or seed phrases
• Verify contract addresses before interactions
• Be cautious of high APY offers (often unsustainable)
• Check for protocol audits before depositing large amounts
• Use hardware wallets for significant holdings

Example Queries

1. "Get a quote to swap 1 ETH for USDC on Uniswap"
2. "Check my Aave position health factor"
3. "Compare lending rates for USDC across Aave and Compound"
4. "What's the TVL and APY for Curve 3pool?"
5. "Help me add liquidity to Uniswap V3 ETH/USDC pool"
