A fiat on-ramp is a service or platform that enables users to convert traditional fiat currency (USD, EUR, GBP, etc.) into cryptocurrency. It is the entry point from the traditional financial system into the crypto ecosystem.
Common On-Ramp Methods
Bank Transfer: Direct transfer from a bank account. Lowest fees but slowest processing (1-5 days).
Credit/Debit Card: Instant purchase but higher fees (typically 2-5%).
Peer-to-Peer (P2P): Direct trades with other users through a platform that provides escrow.
Cash/ATM: Bitcoin ATMs allow cash-to-crypto conversion at physical locations.
Providers
Most centralized exchanges (Binance, Coinbase) serve as fiat on-ramps. Third-party services like MoonPay, Transak, and Ramp Network allow wallet apps and DApps to embed fiat purchasing directly in their interfaces.
Off-Ramp
The reverse process — converting cryptocurrency back to fiat — is called an "off-ramp." This typically involves selling crypto on an exchange and withdrawing to a bank account.
