Why ArbGap

Everything you need to spot an arbitrage opportunity

Real-time data
WebSocket connections to all 4 exchanges simultaneously. Prices update every 100ms — no delays, no cached data.
🧮
Net profit calculation
Spread minus taker fees minus withdrawal fee for the specific network. You see real profit, not gross spread.
🔗
Contract address matching
Pairs are matched exclusively by contract address — no false positives from tokens with the same ticker but different contracts.
📊
Order book depth
Top 5 bid/ask levels for both exchanges in the expanded view. Check liquidity before making a move.
📈
Spread history chart
Mini sparkline for each pair shows how the spread has been moving. Spot trending opportunities, not one-tick flukes.
🔔
