Onramp
A service that lets you convert traditional money (fiat) into cryptocurrency.
In short: An onramp is a service that converts traditional currency (like USD) into cryptocurrency (like USDC), such as Coinbase or MoonPay.
An onramp is your entry point into crypto. When you buy USDC with a debit card, bank transfer, or Apple Pay, you're using an onramp. The service takes your dollars and gives you USDC in your wallet.
Onramps can be built into exchanges like Coinbase or Kraken, embedded in consumer wallets, or run as standalone or peer-to-peer platforms. They handle the payment processing, identity verification, and compliance requirements so you don't have to.
Key factors when choosing an onramp: fees, payment methods supported, speed of delivery, and which chains they support. Buying USDC directly on Base through Coinbase is often the cheapest option.
