Hi Product Hunt! We're Paynoramic, and Marengo is the white-label crypto exchange we built.

Buying exchange software usually starts with a sales deck. We wanted buyers to start with the product, so Marengo runs live, in its own brand. Open Marengo on your phone or your computer and try it yourself, Lite or Pro.

What's inside

Lite for everyone: buy, sell and convert, with the rate and fee shown before you confirm
Pro for traders: candles and indicators, the order book with depth bars, and limit, market and stop orders
24+ markets on one matching engine, with every fill on a double-entry ledger, balanced per asset and reconciled
Compliance tools in the base platform: identity checks with Paynoramic KYC, sanctions screening, the Travel Rule with proof of wallet ownership, transaction monitoring, market-abuse detection, and DAC8 and CARF reports
Broker mode with firm quotes, a FIX 4.4 gateway, and REST and WebSocket APIs with signed keys
AI agents connect read-only by default, and every order one places waits for the customer's approval
Proof of liabilities: daily statements, a public verifier and a check each customer runs on their own entry
Native iOS and Android apps, light and dark, six languages with Arabic right to left, and a staff backoffice with an audit log

For a client, we put your brand, markets and chosen providers on it, deploy it on your infrastructure in about 30 days, and hand over the full source code. Your licence and your partners for custody, banking and liquidity run alongside, and we help you choose them.

Everything about it is on our white-label crypto exchange page. If you are comparing vendors, here is how Marengo compares with other white-label exchange software.

We'd love your feedback
