## Overview

Optimal trade routing across decentralized exchanges by aggregating quotes from 1inch, Paraswap, and 0x. Discovers multi-hop routes, calculates split orders for large trades, and assesses MEV risk to minimize slippage and gas costs.

## Prerequisites

1. Install Python 3.9+ with `httpx`, `pydantic`, and `rich` packages
2. Verify network access to aggregator APIs (1inch, Paraswap, 0x)
3. Optionally add API keys for 1inch and 0x (higher rate limits)
4. Copy settings: `cp ${CLAUDE_SKILL_DIR}/config/settings.yaml.example ${CLAUDE_SKILL_DIR}/config/settings.yaml`

## Instructions

1. Get a quick quote for the single best price with gas cost and effective rate:
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 1.0
   ```
2. Compare all DEXs to see quotes ranked by effective rate (after gas):
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 5.0 --compare
   ```
3. Analyze multi-hop routes to compare direct vs. multi-hop (2-3 pools) with hop-by-hop breakdown:
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 10.0 --routes
   ```
4. Split large orders ($10K+) across multiple DEXs to minimize total price impact:
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 100.0 --split
   ```
5. Assess MEV risk (sandwich attack risk score: LOW/MEDIUM/HIGH) before executing:
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 50.0 --mev-check
   ```
6. Run full analysis combining all features for comprehensive output:
   ```bash
   python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 25.0 --full --output json
   ```

## Output

- **Quick Quote**: Best price, output amount, gas cost, recommended venue
- **Comparison**: All venues ranked by effective rate with price impact and gas
- **Route Analysis**: Direct vs. multi-hop with hop-by-hop breakdown
- **Split Mode**: Optimal allocation percentages with dollar savings vs. single-venue
- **MEV Assessment**: Risk score, exposure estimate, protection recommendations

See `${CLAUDE_SKILL_DIR}/references/implementation.md` for detailed output examples.

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| API Rate Limited | Too many requests | Wait 60s or add API key for higher limits |
| Quote Expired | Stale price data | Refresh before execution; quotes valid ~30s |
| No Route Found | Low liquidity token | Try larger DEXs or reduce trade size |
| Network Timeout | Aggregator down | Retry or check aggregator status page |

See `${CLAUDE_SKILL_DIR}/references/errors.md` for comprehensive error handling.

## Examples

**Compare prices for a 5 ETH swap:**
```bash
python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 5.0 --compare
```

**Find optimal split for a large order:**
```bash
python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 100.0 --split
```

**Check MEV risk before executing:**
```bash
python ${CLAUDE_SKILL_DIR}/scripts/dex_router.py ETH USDC 50.0 --mev-check
```

See `${CLAUDE_SKILL_DIR}/references/examples.md` for multi-hop discovery and MEV-protected execution examples.
