Free crypto arbitrage scanner
with real net profit
Most scanners show a pretty spread %. VoltArb shows what you actually make after fees, slippage, withdrawal, and funding — across 30 CEX and DEX exchanges in real time.
What is a crypto arbitrage scanner?
A crypto arbitrage scanner monitors the same asset on multiple exchanges and highlights price gaps (spreads). Traders buy where it is cheaper and sell where it is more expensive — or hedge with futures for delta-neutral setups.
The hard part is not finding a spread. The hard part is knowing whether the spread survives fees, thin orderbooks, closed withdrawals, and funding payments. That is what VoltArb is built for.
