What is a crypto on-ramp? How people swap pounds for crypto, and back again
By SendPay Business · · 2 min read
An on-ramp is the way someone turns ordinary money, like pounds or euros, into crypto. An off-ramp is the reverse: selling crypto and getting the money back into a bank account. Every crypto app needs both, and they're where most of the rules and checks sit.
How an on-ramp works
- The customer passes identity checks.
- They pay in by bank transfer or card.
- The provider buys the crypto and puts it in the customer's wallet.
How an off-ramp works
The customer sells crypto in the app, the provider converts it to their currency, and pays it out to their bank account or balance. Checks can apply here too, especially on large amounts.
What it costs
Most on-ramps charge a fee plus a spread on the price, and card top-ups usually cost more than bank transfers. Always compare the total amount of crypto you get for the same money.
The rules
Firms that exchange money for crypto usually need a licence or registration. In the UK, that means registering with the FCA for anti-money laundering. That's why identity checks come first, and why most new crypto apps launch with a licensed partner.
