Spot arbitrage opportunities
in real time, before the market corrects.
AltCap scans 9 exchanges every minute and shows you exactly where the same coin is cheap on one and expensive on another. Zero custody. Zero API keys. Just clarity.
The arbitrage window, visualized
When the same coin trades at different prices, that gap is the opportunity.
How AltCap works
Three steps. That's the whole product.
AltCap monitors 9 exchanges every minute and surfaces the biggest live spreads.
Head to the exchange with the lower price and buy your target coin.
Transfer, or use a coin you already hold, and sell on the exchange with the higher price.
Built for retail traders who ship, not gamble.
AltCap doesn't promise returns. It gives you the same information exchanges give to professional market makers — and lets you decide what to do with it.
9 exchanges. One dashboard.
All public-data. We never touch your account.
Real users. Real spreads.
