Payment Gateway & Processing
Turn global crypto holders into active customers. Accept BTC, ETH, USDT, and USDC with zero volatility risk—funds auto-convert and settle directly into your bank account.
Lock exchange rates at the moment of customer checkout. We absorb market price fluctuations so you receive exactly what you billed in your base fiat currency.
Blockchain transactions are final and irreversible. Eliminate fraudulent card chargebacks, disputed payments, and friendly fraud entirely.
Dramatically reduce interchange costs. Processing fees start from 0.5% per successful transaction—a fraction of typical 2.9% + 30¢ credit card interchange rates.
Accept payments from customers in over 150 countries without regional banking friction, currency conversion declines, or cross-border card blocks.
