Accepting cryptocurrency payments has become essential for online businesses expanding their revenue options. The crypto payment gateway landscape offers merchants reliable infrastructure to convert digital assets into stable fiat settlements while managing risk exposure. Choosing the right processor depends on transaction volume, supported currencies, geographic availability, and integration complexity.
This guide compares leading platforms handling crypto-to-fiat conversion, examining fee structures, settlement times, fraud prevention capabilities, and API usability.
NOWPayments
NOWPayments operates as a non-custodial payment processor supporting over 100 cryptocurrencies across 78 blockchains. Unlike traditional processors that hold funds temporarily, NOWPayments routes payments directly between buyer and merchant wallets, reducing counterparty risk. The platform handles both simple checkout widgets and programmatic API integrations suitable for high-volume operations.
The service charges flat fees starting at 0.5% per transaction with no monthly minimums. Settlement options include instant crypto-to-crypto transfers and conversion to major fiat currencies like USD, EUR, and GBP through partner exchanges. For merchants processing mixed currency volumes, this flexibility eliminates the need to maintain separate relationships with individual exchanges.
Integration supports WordPress plugins, WooCommerce extensions, Shopify apps, and REST APIs with comprehensive documentation. The platform also offers recurring billing hooks, invoice webhooks, and multi-signature wallet support for enterprises requiring enhanced security controls.
For businesses evaluating a crypto payment gateway stripe bitpay coinbase ecosystem alongside alternative processors, NOWPayments provides a straightforward entry point with minimal technical overhead and broad asset coverage out of the box.
Stripe
Stripe dominates traditional online payment processing and has expanded its cryptocurrency offerings through Stripe Crypto Payments. The platform enables merchants to accept Bitcoin, Ethereum, Litecoin, and several other tokens while automatically converting them to settled fiat currencies at the point of sale.
Transaction fees sit at 1% plus a fixed component for crypto payments, competitive when compared to dedicated crypto processors. Settlement occurs within minutes of blockchain confirmation, with funds deposited into connected bank accounts on the same business day in supported regions.
Fraud protection benefits from Stripe’s machine learning infrastructure, which analyzes millions of transactions daily to detect anomalies and suspicious behavior. The system integrates with Stripe Radar rules engine, allowing merchants to set custom thresholds for transaction amounts, currency pairs, and geographic restrictions.
API documentation includes libraries for Python, Ruby, JavaScript, PHP, Go, and .NET. However, crypto functionality requires separate onboarding approval and is available only in select jurisdictions including the United States, Canada, and the European Economic Area.
| Feature | Stripe | NOWPayments |
|---|---|---|
| Supported Cryptos | ~10 major coins | 100+ across 78+ chains |
| Transaction Fee | 1% + fixed | 0.5% flat |
| Fiat Settlement | Same-day (limited regions) | Variable by currency pair |
| Non-Custodial | No | Yes |
| Recurring Billing | Via Subscriptions | Built-in webhook support |
BitPay
BitPay has operated since 2011, serving thousands of merchants ranging from small e-commerce stores to enterprise retailers accepting Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Dai, and several stablecoins.
Fee structure charges 1% per transaction with no setup costs or monthly commitments. BitPay converts incoming crypto payments to fiat at quoted exchange rates locked for a brief window, then deposits settled funds into linked bank accounts. Settlement timing ranges from immediate for stablecoin transactions to up to two business days for traditional currency conversions.
The platform provides hosted checkout pages, browser extensions, mobile SDKs for iOS and Android, and REST APIs compatible with major e-commerce frameworks. BitPay’s merchant dashboard includes real-time transaction monitoring, payout history, tax reporting exports, and customer refund capabilities.
One notable constraint is BitPay’s custodial model — funds pass through the company’s controlled wallets before reaching merchant accounts. While this adds operational simplicity, it introduces counterparty risk that some privacy-focused merchants prefer to avoid. BitPay also requires identity verification and business documentation during onboarding.
Coinbase Commerce
Coinbase Commerce focuses specifically on cryptocurrency acceptance without the broader financial services ecosystem that complicates hybrid processors. The platform supports Bitcoin, Ethereum, Litecoin, USDC, Dai, and several other assets with zero transaction fees for merchants.
Setup involves creating a merchant account, generating API keys, and integrating via hosted payment pages or direct API calls. The checkout experience displays real-time exchange rates, countdown timers for rate locks, and QR code payments optimized for mobile shoppers.
Funds settle directly into merchant-controlled Coinbase accounts, which can then be withdrawn to external wallets or converted to fiat through Coinbase’s exchange interface. This approach gives merchants full custody control but requires managing withdrawal workflows independently rather than relying on automated bank deposits.
Customer support operates primarily through email ticketing with response times varying from several hours to a couple of days. Advanced features like webhook-based order confirmation and refund processing are available but require developers to implement additional logic on top of base API responses.
MoonPay
MoonPay positioned itself primarily as an on-ramp and off-ramp solution rather than a pure merchant processor. The platform enables users to purchase cryptocurrencies with fiat currency through credit cards, debit cards, and bank transfers, while also offering sell flows that convert digital assets back to local bank accounts.
For merchants, MoonPay provides embedded buy/sell widgets integrable into websites using iframe embeds or native SDKs. Transaction fees range from 2.5% to 4.5% depending on payment method and volume, notably higher than dedicated payment processors due to compliance and liquidity costs involved in direct fiat-to-crypto conversions.
Regulatory compliance represents MoonPay’s strongest advantage. The platform maintains licenses across multiple jurisdictions, implements KYC/AML checks natively, and supports regulated fiat currencies in Europe, North America, and selected Asian markets. Merchants benefit from MoonPay’s licensed infrastructure rather than building compliance systems internally.
The tradeoff is reduced flexibility for pure payment acceptance scenarios. Merchants seeking straightforward crypto checkout functionality may find MoonPay’s feature set oriented toward exchange-style operations rather than retail transaction processing.
AI-Powered Fraud Detection
Cryptocurrency transactions carry inherent fraud risks that differ fundamentally from card-based payments. While blockchain settlements are irreversible and eliminate traditional chargebacks, they expose merchants to synthetic identity attacks, money laundering attempts, and coordinated exploitation of promotional systems. Modern payment processors address these threats through layered approaches combining rule engines, behavioral analysis, and machine learning models.
Platform-Specific Approaches
Stripe leads with its proprietary Radar system trained on cross-merchant transaction data spanning millions of events. The model evaluates device fingerprints, IP geolocation consistency, purchase velocity patterns, and historical account behavior to assign each transaction a risk score. Merchants configure automated actions such as blocking, flagging, or requiring additional authentication based on these scores.
BitPay employs anomaly detection focused on crypto network patterns. The system flags transactions originating from mixing services, monitors address reputation databases, and applies velocity limits to prevent rapid successive purchases from single funding sources. Stablecoin payments receive additional scrutiny due to their use in wash trading schemes.
NOWPayments leverages third-party blockchain analytics providers to screen incoming addresses against known threat databases including sanctioned entities, darknet marketplaces, and exchange blacklist entries. Transactions matching high-risk criteria trigger manual review workflows before confirmation, adding friction that deters bad actors without impacting legitimate buyers.
Coinbase Commerce relies on Coinbase’s internal risk engine, which shares underlying technology with the consumer exchange platform. Address screening covers billions of on-chain transactions and maintains continuously updated labels for known entities. The system evaluates transaction path complexity, source fund concentration, and destination address clustering.
MoonPay’s compliance-first architecture inherently reduces certain fraud vectors by enforcing identity verification at the point of purchase. The platform balances security and usability by applying progressive verification tiers based on transaction amount and frequency.
Making the Right Choice
Selecting a payment gateway depends on your business model and priorities. High-volume merchants processing diverse crypto assets benefit from NOWPayments’ multi-chain support and non-custodial routing. Businesses already embedded in the Stripe ecosystem gain fraud detection sophistication and unified reporting by enabling crypto alongside card payments.
Merchants prioritizing regulatory compliance should evaluate MoonPay’s infrastructure, while those preferring zero-fee models with direct wallet settlement may lean toward Coinbase Commerce. Each platform presents distinct tradeoffs between ease of integration, asset coverage, cost structure, and risk management depth that warrant careful evaluation against specific operational requirements.
