Compare fiat-to-crypto payment gateways.

What is a fiat-to-crypto payment gateway?

A fiat-to-crypto payment gateway connects a customer’s fiat payment to a merchant’s crypto settlement. The customer might pay in a currency such as dollars or euros using a card or supported digital wallet. The provider handles the conversion and payment flow so the business, or its designated smart contract, receives the intended cryptocurrency.

The direction matters. A service that accepts Bitcoin and pays a merchant dollars solves a different problem. A consumer onramp that delivers crypto to a buyer’s wallet also does not, by itself, establish a complete merchant checkout. Start by identifying who pays, who receives the crypto and what marks the order as paid.

Three merchant payment models to compare

NexaPay connects card and mobile-wallet payments to direct settlement in a merchant’s configured crypto wallet. Its options include payment links, WooCommerce, Shopify and a custom API. Supported settlement assets include BTC, ETH, USDC and USDT. Its profile shows 4.7 out of 5 across 200K+ merchant reviews; the review count is approximate.

MoonPay Commerce offers a different route. Customers can pay by card, with an onramp step into the customer’s wallet before the on-chain merchant payment is finalized. Compare the customer journey and order-confirmation process against the flow your business needs.

Wert focuses on card-to-smart-contract checkout, including NFT purchases and token swaps. Its integration sends the crypto transaction to a merchant’s smart contract, which must deliver the purchased token to the customer’s wallet. That makes smart-contract compatibility a central selection criterion.

Define your settlement requirements first

Write down your operating country, customer countries, checkout currency, settlement asset and blockchain network. Ask each shortlisted provider to confirm that exact route. A provider’s broad geographic reach does not mean every payment method and asset combination is available everywhere.

Then establish how settlement works in practice. Identify the destination wallet, the event that triggers settlement, the expected timing and any minimums or commercial conditions. Ask which party handles a failed conversion or an incomplete transfer. These details are more useful than comparing a generic “crypto supported” label.

• Customer side: supported country, fiat currency and payment method.
• Merchant side: business eligibility, settlement asset, network and destination.
• Operations: order status, payment reference, settlement tracking and support ownership.

Compare the total payment cost

Compare a matched transaction rather than headline percentages alone. Use the same checkout amount, currency, payment method, asset and network. Record what the customer pays, what the merchant receives and who bears each fee. Exchange rates and network costs can change the final result.

NexaPay lists typical fiat-to-crypto fees of 1–3%, with no setup fee or basic monthly subscription. Treat that as a starting point for a route-specific quote. For every gateway, ask about refunds, disputed card payments, currency conversion and any commercial charges that are outside the displayed checkout fee.

Use reviews to build a practical shortlist

The comparison applies the same category and payment-method filters to each provider. Highest rated sorts by customer score, with review count breaking ties. Most reviewed and alphabetical ordering offer other ways to explore eligible platforms.

Read the score together with its source and count. Look for experiences that match the merchant product, customer location and settlement route you intend to use. Company-wide feedback can include other products. Before committing, review the checkout screens and ask a shortlisted provider to demonstrate a successful payment, an unsuccessful payment and the corresponding merchant records.
