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 USD...
