Finding Arbitrage Opportunities
Overview
Detect and analyze arbitrage opportunities across cryptocurrency exchanges and DeFi protocols. Aggregates prices from CEX and DEX sources, calculates net profit after fees, and identifies direct, triangular, and cross-chain arbitrage paths.
Prerequisites
- Python 3.9+ with
httpx, rich, and networkx packages
- Internet access for API calls (no API keys required for basic use)
- Optional: Exchange API keys for real-time order book access
- Understanding of arbitrage concepts and trading fees
Instructions
Quick spread scan on a specific pair:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py scan ETH USDC
Shows current prices per exchange, spread %, estimated profit after fees, and recommended action.
Multi-exchange comparison across specific exchanges:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py scan ETH USDC \
--exchanges binance,coinbase,kraken,kucoin,okx
DEX price comparison across decentralized exchanges:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py scan ETH USDC --dex-only
Compares Uniswap V3, SushiSwap, Curve, Balancer with gas cost estimates.
Triangular arbitrage discovery within a single exchange:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py triangular binance --min-profit 0.5
Cross-chain opportunities across different blockchains:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py cross-chain USDC \
--chains ethereum,polygon,arbitrum
Real-time monitoring with threshold alerts:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py monitor ETH USDC \
--threshold 0.5 --interval 5
Export opportunities for bot integration:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py scan ETH USDC --output json > opportunities.json
Output
- Quick mode (default): Best opportunity with profit estimate, buy/sell recommendation, risk level
- Detailed mode (
--detailed): All exchange prices, fee breakdown, slippage estimates, historical spread context
- Monitor mode: Real-time updates with threshold alerts and trend indicators
See ${CLAUDE_SKILL_DIR}/references/implementation.md for exchange fee tables and output format examples.
Error Handling
| Error |
Cause |
Fix |
| Rate limited |
Too many API requests |
Reduce polling frequency or add API key |
| Stale prices |
Data older than 10s |
Flagged with warning; retry |
| No spread |

Examples
Quick ETH/USDC spread scan - Find best buy/sell across all CEX exchanges:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py scan ETH USDC
Sample detection output:
ARB OPPORTUNITY: ETH/USDC
Buy: Binance @ $3,198.50 | Sell: Coinbase @ $3,214.20
Spread: 0.49% | Net Profit (after fees): 0.29% ($9.27 per ETH)
Risk: LOW | Confidence: HIGH | Window: ~30s
Triangular arb on Binance - Discover circular paths with minimum 0.5% net profit:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py triangular binance --min-profit 0.5
Cross-chain USDC opportunities - Compare stablecoin prices across L1/L2 chains:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py cross-chain USDC --chains ethereum,polygon,arbitrum
Calculate exact profit - Detailed fee breakdown for a specific trade:
python ${CLAUDE_SKILL_DIR}/scripts/arb_finder.py calc \
--buy-exchange binance --sell-exchange coinbase --pair ETH/USDC --amount 10 # 10 = trade size in ETH
