Fiat to Crypto Payment Gateways — On-Ramp & Off-Ramp Guide 2026
What is a fiat-to-crypto payment gateway? Compare 7 gateways that convert between fiat and crypto: on-ramps, off-ramps, fees, and which is best for your business.
Key Takeaways
- A fiat-to-crypto payment gateway converts traditional currency (USD, EUR, GBP) into cryptocurrency and back — handling the exchange automatically for merchants
- On-ramp means customers pay in fiat and the merchant receives crypto. Off-ramp means customers pay in crypto and the merchant receives fiat
- Seven gateways currently offer fiat conversion: CoinGate, BitPay, NOWPayments (partial), Confirmo, ForumPay, B2BinPay, and CryptoPay
- Fees range from 0.5% (ForumPay) to 1% (BitPay, CoinGate). All fiat-capable gateways require some level of KYC
What Is a Fiat-to-Crypto Payment Gateway?
A fiat-to-crypto payment gateway bridges the gap between traditional money and cryptocurrency. It handles the conversion automatically so merchants do not have to use exchanges manually. The customer pays with one currency, the merchant receives another, and the gateway handles everything in between.
This matters because most businesses still operate in fiat. Rent, payroll, taxes — all denominated in USD, EUR, or GBP. A pure crypto gateway forces you to hold volatile assets or manually sell on exchanges. A fiat-capable gateway eliminates that friction entirely.
On-Ramp vs Off-Ramp: What Is the Difference?
On-Ramp (Fiat → Crypto)
Customer pays in fiat (credit card, bank transfer). The gateway converts the fiat to crypto and delivers it to the merchant's wallet.
Use case: Merchants who want to accumulate crypto from sales.
Off-Ramp (Crypto → Fiat)
Customer pays in crypto. The gateway converts the crypto to fiat and deposits it in the merchant's bank account.
Use case: Businesses that need fiat for operations but want to accept crypto payments.
Most fiat-capable gateways focus on the off-ramp direction — accepting crypto and settling in fiat. This is the more common merchant need.
Which Gateways Support Fiat Conversion?
*NOWPayments auto-converts to stablecoins (USDT/USDC) which is functionally similar to fiat but not actual bank deposits.
How to Choose the Right Fiat-Crypto Gateway
You need USD settlement
Your best options are BitPay (widest fiat support, 1% fee), B2BinPay (lower fees at volume), or ForumPay (0.5% with POS).
You need EUR settlement
All seven gateways support EUR. Confirmo (0.8%) and ForumPay (0.5%) are the cheapest options for EU merchants.
You need GBP settlement
Only CryptoPay and B2BinPay offer GBP settlement. CryptoPay is the better option for smaller UK businesses, B2BinPay for enterprises.
You want the lowest fees
ForumPay at 0.5% is the cheapest with actual fiat settlement. B2BinPay starts at 0.4% but requires volume negotiation.
Frequently Asked Questions
What is a fiat-to-crypto payment gateway?
A payment gateway that converts between traditional currency (fiat) and cryptocurrency. It lets merchants accept crypto and receive fiat, or accept fiat and receive crypto, without manually using an exchange.
Do all crypto gateways support fiat settlement?
No. Most crypto gateways are crypto-in, crypto-out. Only about half of the major gateways offer fiat settlement, and all of them require some level of KYC to comply with banking regulations.
Can I accept crypto without KYC and still get fiat?
Not directly. Bank settlements require identity verification. The workaround is to use a no-KYC gateway that auto-converts to stablecoins (like NOWPayments), then sell the stablecoins on an exchange when you are ready.
What is the difference between on-ramp and off-ramp?
On-ramp converts fiat to crypto (customer pays with credit card, merchant gets crypto). Off-ramp converts crypto to fiat (customer pays with crypto, merchant gets bank deposit). Most merchant gateways focus on off-ramp.
Which fiat-to-crypto gateway has the lowest fees?
ForumPay at 0.5% for self-service merchants. B2BinPay starts at 0.4% but requires volume-based pricing negotiation. BitPay and CoinGate both charge 1%.
Is stablecoin settlement the same as fiat settlement?
Not exactly. Stablecoins (USDT, USDC) are pegged to USD but are still crypto tokens. You hold them in a crypto wallet, not a bank account. You still need to sell them on an exchange to get actual dollars in your bank.
How fast is fiat settlement from crypto payments?
Typically 1-3 business days. SEPA transfers in the EU are usually same-day or next-day. Wire transfers to US banks take 2-3 business days. UK Faster Payments can be same-day.
Can I use a fiat-to-crypto gateway for recurring subscriptions?
Some gateways support this. BitPay and CoinGate both offer subscription billing with fiat settlement. See our recurring crypto payments guide for details.
