In today’s evolving financial ecosystem, the ability to move seamlessly between fiat currencies and cryptocurrencies has become essential. Whether you’re running a crypto exchange, an e-commerce site, or a global SaaS platform, integrating both a fiat to crypto payment gateway and a crypto to fiat payment gateway ensures your business can thrive in a multi-currency, borderless economy.
These gateways function as vital financial infrastructure — allowing businesses to onboard users with fiat, accept crypto payments, and withdraw back to fiat when needed.
What Is a Fiat to Crypto Payment Gateway?
A fiat to crypto payment gateway enables users to buy digital assets like Bitcoin, Ethereum, or stablecoins using traditional currencies such as USD, EUR, GBP, or JPY.
How It Works:
- The user pays with fiat (via card, bank transfer, or mobile payment).
- The gateway processes the transaction.
- The equivalent amount of crypto is sent to the user’s wallet.
This is the on-ramp — converting new users into crypto participants.
Popular fiat to crypto gateways include:
- MoonPay
- Ramp
- Transak
- Binance Connect
What Is a Crypto to Fiat Payment Gateway?
A crypto to fiat payment gateway performs the reverse operation. It allows users or businesses to convert their crypto holdings into local fiat currency and receive the funds via bank transfer or card deposit.
How It Works:
- The user sends crypto to the gateway.
- The gateway converts it to fiat at the current exchange rate.
- The fiat is deposited to a linked bank account or debit card.
This off-ramp is crucial for liquidity, especially for freelancers, Web3 teams, and merchants accepting crypto.
Popular crypto to fiat gateways include:
- BitPay
- Coinbase Commerce
- NOWPayments
- Mercuryo
