Routing DEX Trades
Overview
This skill provides optimal trade routing across decentralized exchanges by aggregating quotes from multiple sources (1inch, Paraswap, 0x), discovering multi-hop routes, calculating split orders for large trades, and assessing MEV risk. It helps traders execute at the best prices while minimizing slippage and gas costs.
Prerequisites
Before using this skill, ensure you have:
- Python 3.9+ with
httpx, pydantic, and rich packages
- Network access to aggregator APIs (1inch, Paraswap, 0x)
- Optional: API keys for 1inch and 0x (higher rate limits)
- Environment variables configured in
{baseDir}/config/settings.yaml
- Understanding of DeFi trading concepts (slippage, price impact, MEV)
Instructions
Step 1: Configure API Access
- Copy settings template:
cp {baseDir}/config/settings.yaml.example {baseDir}/config/settings.yaml
- Add optional API keys:
api_keys:
oneinch: "your-1inch-api-key"
zerox: "your-0x-api-key"
- Set preferred chain:
ethereum, arbitrum, polygon, or optimism
Step 2: Quick Quote (Single Best Price)
Use Bash(crypto:dex-router) to get the best price across aggregators:
python {baseDir}/scripts/dex_router.py ETH USDC 1.0
This returns the single best route with price, gas cost, and effective rate.
Step 3: Compare All DEXs
For detailed comparison across all sources:
python {baseDir}/scripts/dex_router.py ETH USDC 5.0 --compare
Output includes quotes from each aggregator with:
- Output amount and rate
- Price impact percentage
- Gas cost in USD
- Effective rate (after gas)
Step 4: Analyze Routes (Multi-Hop Discovery)
For trades where multi-hop might be cheaper:
python {baseDir}/scripts/dex_router.py ETH USDC 10.0 --routes
Discovers and compares:
- Direct routes (single pool)
- Multi-hop routes (2-3 pools)
- Shows hop-by-hop breakdown with cumulative impact
Step 5: Split Large Orders
For whale-sized trades ($10K+), optimize across multiple DEXs:
python {baseDir}/scripts/dex_router.py ETH USDC 100.0 --split
Calculates optimal allocation:
Split Recommendation:
60% via Uniswap V3 (60 ETH → 152,589 USDC)
40% via Curve (40 ETH → 101,843 USDC)
─────────────────────────────────────────────
Total: 254,432 USDC (vs. 251,200 single-venue)
Improvement: +1.28% ($3,232 saved)
Step 6: MEV Risk Assessment
Check sandwich attack risk before executing:
python {baseDir}/scripts/dex_router.py ETH USDC 50.0 --mev-check
Returns risk score and recommendations:
- LOW: Safe to execute via public mempool
- MEDIUM: Consider private transaction
- HIGH: Use Flashbots Protect or CoW Swap
Step 7: Full Analysis
Combine all features for comprehensive analysis:
python {baseDir}/scripts/dex_router.py ETH USDC 25.0 --full --output json
See {baseDir}/references/examples.md for detailed output examples.
Output
The router provides:
Quick Quote Mode:
- Best price across aggregators
- Output amount and effective rate
- Gas cost estimate
- Recommended venue
Comparison Mode:
- All venues ranked by effective rate
- Price impact per venue
- Gas costs compared
- Liquidity depth indicators
Route Analysis:
- Direct vs. multi-hop comparison
- Hop-by-hop breakdown
- Cumulative price impact
- Gas cost per route type
Split Mode:
- Optimal allocation percentages
- Per-venue amounts
- Total vs. single-venue comparison
- Dollar savings estimate
MEV Assessment:
- Risk score (LOW/MEDIUM/HIGH)
- Exposure estimate
- Protection recommendations
- Alternative venues (CoW Swap, etc.)
Trade Size Recommendations
| Trade Size | Strategy | Notes |
|---|
| < $1K | Direct quote | Gas may exceed savings from optimization |
| $1K - $10K | Compare + routes | Multi-hop can save 0.1-0.5% |
| $10K - $100K | Split analysis | 2-3 way splits reduce impact |
| > $100K | Full + MEV + private TX | Consider OTC or algorithmic execution |
Error Handling
See {baseDir}/references/errors.md for comprehensive error handling.
Common issues:
- API Rate Limited: Wait 60s or use API key for higher limits
- Quote Expired: Refresh before execution; quotes valid ~30s
- No Route Found: Token may have low liquidity; try larger DEXs
- Network Timeout: Retry or check aggregator status
Examples
See {baseDir}/references/examples.md for detailed examples including:
- Basic ETH→USDC swap comparison
- Multi-hop route discovery
- Large order splitting
- MEV-protected execution paths
