Fiat to Crypto Payment Gateway for Merchants: 2026 Top 3

A fiat to crypto payment gateway for merchants lets a customer pay in dollars, euros or pounds by card, wallet or bank transfer while the merchant receives stablecoins or other crypto. The products that do this look similar on a landing page, but they differ on three questions that decide whether they fit your business: who verifies whom, who holds the money in between, and what you are allowed to sell.

Quick answer: PayMeGate is our pick for online merchants who want card, Apple Pay and Google Pay payments settled as crypto to their own wallet without uploading business documents at signup: it charges a 1% platform fee plus provider and network fees, with $1 to $30 order minimums. MoonPay Commerce suits merchants whose customers already hold crypto and who want optional fiat settlement (from 1% to 2%, high-risk minimum 2%, plus 0.50% for auto-offramp). Transak is the developer pick for embedding an on-ramp or virtual bank accounts, but it requires KYB before going live.

Editorial disclosure

PayMeGate publishes this article and sells payment processing software, so we have a commercial interest in the ranking, and PayMeGate is listed first because this is our own site. We checked every fee, verification requirement and policy below on each provider's official website or documentation on 2 October 2026. Fees and terms change, so confirm the current figures before you sign up.

Fiat to crypto gateways at a glance

All three add crypto settlement to existing payment infrastructure; the table shows where they differ.

Provider	Model	Merchant fee	Merchant onboarding	Customer checks	Settles in
PayMeGate	Card and crypto checkout, crypto payout	1% + provider/network fees; $1–$30 minimum	Name, email, optional website, password; no document uploads	Set by the payment provider (often a quick camera ID check)	USDC, USDT, ETH or POL to your wallet
MoonPay Commerce	Crypto checkout with a pay-with-card option	2% standard, 1% HelioX; 2% minimum for high-risk	Sumsub verification (creator or business)	Card leg handled by MoonPay	Crypto to your wallet, or USD/EUR/GBP via auto-offramp (+0.50%)
Transak	On-ramp widget, API and virtual accounts	Transak fee by payment method + optional partner fee up to 5%	KYB required for production keys	Light, Standard or Enhanced KYC by amount	Crypto to the configured wallet address

What is a fiat to crypto payment gateway?

A fiat to crypto payment gateway takes a payment in a traditional currency and delivers a crypto asset, usually a stablecoin such as USDC, to a destination wallet address. It sits between conventional payment rails (card networks, Apple Pay, Google Pay, bank transfers) and blockchain networks, and it does the currency conversion at an exchange rate in between. In other words, it connects traditional finance, where customers pay with traditional payment methods in traditional currencies, to the world of digital assets, where the merchant receives a crypto asset.

There are three ways the industry packages this payment infrastructure, and they are not interchangeable:

1. Gateway checkout with crypto payouts. The customer pays the merchant by card or wallet on a hosted checkout. A payment provider runs the card processing and customer checks, the funds are converted, and the merchant's wallet receives crypto. This is PayMeGate's model.
2. Crypto checkout with a card option. The checkout is built for customers who pay with crypto or stablecoins they already hold, and a "pay with card" option lets non-crypto users pay while the merchant still receives crypto. This is MoonPay Commerce's model.
3. On-ramp widget or virtual accounts. Your users buy crypto inside your app or website, much as they would on crypto exchanges, or send bank transfers to a virtual account that converts automatically into crypto. This is Transak's model, built mainly for wallets, exchanges, fintech apps and payroll platforms.

On-ramps vs off-ramps

A fiat on-ramp turns fiat currency into crypto. An off-ramp does the reverse: it converts crypto back into fiat and sends it to bank accounts. A fiat to crypto gateway for merchants is an on-ramp pointed at a business: the customer pays fiat, the merchant ends up with crypto. Some gateways add an off-ramp so you can settle back into dollars, euros or pounds, which is what MoonPay Commerce's 0.50% auto-offramp does.

Who verifies whom: merchant KYC, KYB and customer KYC

Most confusion about "no-KYC" gateways comes from mixing up three separate checks:

Check	Who is checked	PayMeGate	MoonPay Commerce	Transak
Merchant onboarding	You, the seller	Account details; no identity or business-document uploads	Sumsub verification as a creator or business	KYB before production keys
Customer identity verification	Your buyer	Applied by the independent payment provider; PayMeGate's FAQ says customers may need a mobile-camera ID check, which some providers skip for smaller orders	Card leg run by MoonPay	Light KYC ($10–$200), Standard (up to $25,000, photo ID and live selfie) or Enhanced (up to $75,000)
Sanctions and transaction monitoring	Both	Provider-side risk, fraud and sanctions checks	OFAC country and wallet blocking with geo-IP and Chainalysis	Risk engine on every card payment

So the honest answer to "is there a fiat to crypto gateway that doesn't require KYC?" is no, not end to end. Card payments always pass through a regulated party that runs anti money laundering and identity checks on the payer at some level. What differs is whether the merchant has to upload a passport and company documents before taking a payment. PayMeGate does not ask for those uploads at signup; MoonPay Commerce and Transak do verify the business.

How we chose

We started from the card-to-crypto candidates we track (NOWPayments, Transak, MoonPay and Mercuryo) and compared them with PayMeGate on what we could verify live today:

1. Fees: the platform fee, plus any conversion, settlement or partner fees.
2. Onboarding: what the merchant must provide before the first live payment.
3. Customer experience: which payment methods buyers can use and what checks they face.
4. Settlement model: which assets and networks you receive, and whether fiat settlement is available.
5. Restrictions: prohibited businesses and geographic limits.

NOWPayments was left out: when we read its terms of service on 1 October 2026 (version updated 31 August 2026), section 15.1 said its services are not rendered to residents or citizens of the EU, UK, US or UAE, which rules it out for most of this article's readers. Mercuryo's website was not available from our location today ("Service is unavailable for your region"), so we could not verify its terms.

1. PayMeGate: best fiat to crypto payment gateway for online merchants

PayMeGate puts card and crypto checkout into one order flow and pays out in crypto to a wallet you configure. Its card gateway accepts Visa, Mastercard, Maestro, American Express, Apple Pay and Google Pay, and its FAQ also lists PayPal, Revolut, SEPA transfers and select local payment methods, depending on the provider. The customer pays in fiat; you accept crypto payments too, on the same checkout.

PayMeGate fees (checked 2 October 2026)

Item	Fee
Card gateway platform fee	1%
Crypto gateway platform fee	1%
Provider, exchange and network fees	Set by the underlying providers, vary by method and order
Minimum order	$1 to $30, depending on the payment provider
Card payouts	Instant USDC payouts to your wallet

How a card payment becomes crypto

According to PayMeGate's payment gateway page, the flow is:

1. Install a plugin or paste your wallet in the dashboard.
2. Enter a USDC-compatible EVM wallet address.
3. The customer is redirected to the payment provider at checkout.
4. A temporary wallet is assigned per order.
5. The provider handles customer verification (about two minutes).
6. The order is marked complete automatically and the crypto is sent to your wallet.

Settlement can arrive in USDC, USDT, ETH or POL on a compatible network, depending on the asset, network, provider outcome and timing of each order.

Key features

• No identity or business-document uploads at merchant signup: the form asks for a merchant name, email, an optional website and a password
• Plugins for WHMCS 8.8+, WooCommerce, PrestaShop 8.1–9.x and OpenCart 4.x
• A direct API with an order.paid webhook; externalId and metadata come back unchanged for reconciliation
• Mass payouts with up to 19 splits and cross-chain payments on the crypto side
• Unlimited websites and an optional custom checkout domain

Best for

E-commerce stores, SaaS and digital-goods sellers who want card customers, a crypto payout and fast setup, and who prefer not to hold funds with a custodian.

Things to consider

• PayMeGate is software, not a payment institution. Its site says all processing is handled by independent third-party providers, which set their own verification, eligibility and geographic rules.
• Customer checks still apply depending on the payment method; some buyers will see a camera ID step.
• Its terms prohibit fake shops, adult content, gambling, intoxicating substances and any criminal activity, and PayMeGate says it can restrict accounts for abuse or prohibited use.
• Card disputes can still apply under the provider's rules; on-chain payouts are generally irreversible.

2. MoonPay Commerce: best for crypto-native customers

MoonPay Commerce (formerly Helio) is a crypto payment gateway for merchants: checkout, pay links, subscriptions, deposits and a Shopify plugin. Its "Pay with card" option lets non-crypto users pay while the merchant receives crypto, and merchants can receive crypto instantly or auto convert to USD, EUR or GBP in supported regions.

MoonPay Commerce fees (checked 2 October 2026)

Item	Fee
Standard transaction fee	2%
HelioX tier (holding a HelioX Pass NFT)	1%
High-risk platforms	Minimum 2%
Swaps	0.25%
Auto-offramp (fiat settlement)	0.50%
High-volume merchants	Custom pricing

Key features

• Supports USDC, USDT, BTC, SOL, ETH, ERC-20 and SPL tokens
• Pay links for subscriptions, content and products; checkout widget, SDK and webhooks
• Merchant verification through Sumsub as a creator (with a linked X account) or a business
• Blocks OFAC-sanctioned countries and wallets using geo-IP and Chainalysis
• MoonPay USA LLC is a registered money service business (NMLS ID 2071245), per MoonPay's site

Best for

Merchants whose customers already hold stablecoins or SOL, and who want the option to settle in fiat currency.

Things to consider

• Its terms say MoonPay Commerce does not take custody of crypto, transfers run through smart contracts and embedded wallets directly from buyer to merchant, and each crypto transaction is irreversible, so refunds are your job.
• The 2% minimum for high-risk platforms doubles the cost compared with the HelioX rate.
• Business verification through Sumsub is required for the verified-merchant status.

3. Transak: best for developers embedding an on-ramp

Transak is a developer toolkit for fiat on-ramp and off-ramp: your users buy and sell crypto inside your app, and Transak handles KYC, compliance, fiat payment methods and crypto coverage. It also offers Virtual Account Payments: named virtual bank accounts in currencies such as USD and GBP, each mapped to a wallet address, asset and network, so incoming bank transfers convert automatically into crypto.

Transak fees (checked 2 October 2026)

Item	Fee
Transak fee	Percentage set by payment method (card or bank transfer); its docs' worked example uses 0.99% for a GBP bank transfer
Partner fee	Optional, up to 5%, set by you on top of Transak's fee
Network/exchange fee	Gas plus liquidity withdrawal fee, set by the market
Partner fee payouts	Manual, in USDC or USDT on a network you choose (for example Polygon or ERC-20)

Key features

• Hosted widget, iframe, mobile SDKs, whitelabel API and headless Apple Pay, Google Pay and card flows
• Apple Pay and Google Pay supported in the widget
• Light KYC (name, date of birth, address, phone; SSN in the US) for $10 to $200 in eligible countries
• Staging keys before KYB; production after KYB approval
• Virtual Account Payments for payroll-to-stablecoin and recurring fiat-in, crypto-out flows

Best for

Wallets, exchanges, fintech apps and platforms that want users to fund crypto balances inside their own product, and developers who want a direct API and white-label control.

Things to consider

• KYB is required before live orders, and US KYC requires a Social Security Number.
• Some US states restrict certain tokens; Transak's docs say to filter supported assets by state.
• Virtual Account Payments is scoped to bank transfers, needs Standard KYC for end users and excludes direct B2C app flows.
• Transak is designed for users buying crypto, not for merchant checkout. Ask Transak whether sending purchased crypto to your merchant wallet fits its rules before using it as a checkout.
• Transak's main website blocked our checks today, so we could not read its acceptable-use list; ask for it during KYB.

How to choose the right crypto payment gateway for your business

Fiat to crypto payment gateways operate very differently behind similar checkout pages. Before you add one to your payments stack, check these core capabilities of its payment infrastructure:

Question	Why it matters
Settlement model	Do you receive stablecoins in your own wallet, a balance held by the provider, or fiat currency in bank accounts? This decides your crypto exposure and your cash flow.
Settlement speed	How long from payment initiation to funds in your wallet? It depends on provider confirmation and blockchain networks, not just the gateway.
Asset support	Which supported assets and chains can you receive? A USDC payout on the wrong network can delay or lose funds.
Automatic conversion	Can the gateway automatically convert to fiat if you do not want to hold digital assets? MoonPay Commerce charges 0.50% for this; PayMeGate pays out in crypto only.
Verification process	What does the merchant verification process ask for, and what identity verification will your customers see?
Regulatory coverage	Large providers advertise multiple licenses across multiple jurisdictions; smaller gateways rely on licensed partners. Ask who holds the regulatory approvals for each part of the flow.
Custody and private keys	Non-custodial gateways send funds straight to a wallet you control. You keep the private keys, and you also carry the risk of losing them.
Operational complexity	One gateway that handles cards and crypto avoids multiple vendor relationships and multiple systems to reconcile.

Global enterprises that operate globally usually want stablecoin accounts, broad stablecoin capabilities, multi-currency stablecoin infrastructure and dedicated licensing coverage, and they negotiate custom pricing. Smaller global businesses with frequent transactions, such as digital-goods sellers, subscription services and other online business models, usually care more about quick onboarding, plugins for e-commerce platforms and low per-order fees. Those smaller sellers are who this comparison is for.

Fees and settlement: what a $100 card order costs

Using only the published platform fees (provider, network and FX costs are extra and vary):

Provider	Platform fee on $100	Notes
PayMeGate	$1.00	Plus provider and network fees; minimum order $1–$30
MoonPay Commerce	$2.00 standard ($1.00 HelioX)	+$0.50 if auto-converted to fiat
Transak	Payment-method fee	Plus any partner fee you add (up to $5)

Settlement speed depends on three things: when the payment provider confirms the payment, how long the blockchain transaction takes, and network conditions. Stablecoin payments to your own wallet remove the bank settlement wait and can make cross border transactions simpler, but you then own the job of converting crypto and keeping records for tax. That is part of running crypto operations: if you would rather avoid digital asset operations entirely, a gateway with fiat settlement is the better fit.

How to integrate a fiat to crypto gateway

• Payment links: the fastest start. Create a link per order or product and send it to the customer. PayMeGate and MoonPay Commerce both offer links.
• E-commerce plugins: PayMeGate has WHMCS, WooCommerce, PrestaShop and OpenCart modules; MoonPay Commerce has a Shopify plugin.
• Direct API: create orders server-side, receive a webhook when paid, and match it to your cart or invoice with your own reference (PayMeGate returns externalId and metadata unchanged).
• Embedded widget or SDK: Transak's widget and SDKs put the on-ramp inside your app.

Whichever you use, test with small orders first, check that each payment appears exactly once in your system, and confirm the destination wallet address and network before going live. Sending to the wrong network is the most expensive integration mistake.

Risks and compliance requirements

A gateway's onboarding rules do not move your own legal duties:

• AML stays with you. Depending on your business and country, you may have your own anti money laundering and record-keeping obligations even when a provider checks your customers.
• Card-network rules apply. Card payments still run under Visa and Mastercard rules, which ban illegal and infringing sales.
• Chargebacks. Provider-funded card flows can be disputed under the provider's rules. Crypto received on-chain is generally irreversible, so keep evidence of delivery.
• Sanctions and transaction monitoring. All three providers screen for sanctions and monitor transactions; you should not serve sanctioned people or regions either.
• Tax. Receiving stablecoins is income like any other. Keep the fiat value at the time of each payment for your records.
• Licensing. Whatever payment infrastructure you choose, money transmission rules differ by country and US state. PayMeGate does not claim to be licensed or regulated; it says processing is handled by independent providers.

Frequently asked questions

What is a fiat to crypto payment gateway?

It is a service that lets customers pay in a traditional currency by card, wallet or bank transfer while the merchant receives crypto, usually a stablecoin, in a wallet. The gateway handles conversion and passes the payment through regulated providers.

What does fiat on-ramp mean?

A fiat on-ramp converts fiat money into crypto. The off-ramp does the opposite, turning crypto back into money in a bank account.

Can I buy crypto with fiat on an on-ramp?

Yes. On-ramps such as Transak let users buy crypto with cards, Apple Pay, Google Pay or bank transfers, subject to KYC checks that scale with the amount.

Is there a fiat to crypto payment gateway that doesn't require KYC?

Not end to end. Merchant signup can be document-free, as it is at PayMeGate, but the providers that process cards run customer verification, fraud and sanctions checks, which can include a quick camera ID check.

Which fiat on-ramp provider is best for crypto?

For in-app crypto purchases, Transak offers tiered KYC and white-label APIs. For merchant checkout with crypto payouts, a gateway such as PayMeGate is a better fit than a consumer on-ramp.

Can I accept payments in crypto?

Yes. A crypto payment gateway gives you a checkout, payment links or plugins and sends payments to your wallet. PayMeGate and MoonPay Commerce both accept crypto directly as well as cards.

How do I accept Bitcoin payments?

Use a gateway that supports BTC (PayMeGate and MoonPay Commerce both list it), connect your wallet, and add a checkout link or plugin to your store. Decide whether you want to keep BTC or convert it.

What payment gateway is best for high-risk businesses?

One that accepts your business type in its terms and is transparent about fees. PayMeGate does not require document uploads at signup but bans illegal activity; MoonPay Commerce charges high-risk platforms at least 2%.

Which crypto payment processor is best for businesses?

PayMeGate for card-to-crypto checkout with plugins and a 1% platform fee; MoonPay Commerce for crypto-native customers and optional fiat settlement; Transak for apps that need an embedded on-ramp.

How to make a crypto payment gateway?

Building your own means custody, conversion, compliance and card processing partners. Most merchants integrate an existing gateway through payment links, plugins or a direct API instead.

How can you tell if someone is a crypto scammer?

Warning signs include promises of guaranteed returns, pressure to pay quickly, requests to send crypto to a personal wallet, and refusing to put terms in writing. Check a provider's published fees, terms and company details before you connect your wallet.

Final verdict

For most online merchants, PayMeGate is the most practical fiat to crypto payment gateway in this comparison: customers pay by card, Apple Pay or Google Pay, you receive USDC or other supported crypto in your own wallet, and signup takes account details rather than document uploads. The platform fee is 1% plus provider and network costs. Choose MoonPay Commerce if your buyers already pay in crypto and you want optional fiat settlement, and Transak if you are building an app that needs an embedded on-ramp.
