What is On-ramp?

A service that allows users to convert traditional fiat currency into cryptocurrency.

Last updated June 12, 2026

An on-ramp is a service or platform that lets you convert traditional fiat currency (USD, EUR, GBP, etc.) into cryptocurrency. Exchanges like Coinbase, Kraken, and Binance are the most common on-ramps. Payment-specific on-ramps like MoonPay, Wyre (now part of MoonPay), Sardine, and Stripe’s crypto on-ramp let merchants and developers embed “buy with credit card” flows directly into their apps.

How on-ramps work

  1. You create an account and complete identity verification (KYC), typically required by regulation.
  2. You link a payment method — usually a bank account, debit card, or credit card.
  3. You specify the cryptocurrency and amount you want to buy.
  4. The on-ramp debits your payment method and credits your wallet with the purchased crypto.

The reverse process — converting crypto back to fiat — is called an off-ramp.

Costs and considerations

On-ramp fees vary widely. They typically include a spread (the difference between the market price and the price you actually pay) plus an explicit transaction fee. Card purchases usually cost 2-4% in fees; bank transfers (ACH, SEPA) are usually much cheaper but slower.

For most users, the cheapest path is to fund a major exchange via bank transfer, buy crypto there, and withdraw to your own wallet. Buying crypto directly inside a wallet app (MetaMask, Trust Wallet) tends to be the most expensive, because the wallet app is using an embedded on-ramp that charges a premium for the convenience.

KYC and limits

On-ramps are regulated as money services businesses in most jurisdictions and are required to perform Know Your Customer (KYC) checks. Daily and annual purchase limits depend on the verification level you complete — fully verified accounts can typically buy tens of thousands of dollars per day.

Why on-ramps matter for crypto adoption

The user experience of the on-ramp is often the most friction-filled part of paying with crypto. If a merchant is going to accept crypto from non-crypto-native customers, the merchant usually has to embed an on-ramp so that the customer can buy crypto as part of the checkout flow. This is the model behind services like Coinbase’s hosted checkout.
