An onramp turns traditional money into cryptocurrency. You pay with a supported card, bank transfer, or another payment method, and receive crypto in a wallet. Start here if you want to buy crypto for yourself, or let people buy it inside your app.
An offramp runs in the opposite direction: you send crypto and receive fiat through a supported payout method. A provider may offer both products, but buy and sell coverage can differ. Check the asset, network, currency, and payout method for your particular route.
A payment gateway describes a checkout service for a business. The phrase “crypto payments” alone does not establish which currency your customer pays or which asset you receive. Some services accept crypto from customers and settle fiat; others let customers pay by card and complete an on-chain purchase. These are different flows.
For fiat-to-crypto checkout, confirm the full path: the customer pays fiat, conversion happens, and your business or smart contract receives the intended crypto asset. NexaPay settles card payments directly to a merchant’s crypto wallet. MoonPay Commerce and Wert offer other versions of fiat-to-crypto checkout, with different integration requirements.
Choose the category first, then compare the details. Availability, identity checks, total cost, settlement, integrations and customer feedback all matter. Provider profiles show product information and review evidence so you can assess the complete payment flow.
