BitPay

Best forBusinesses wanting to accept Bitcoin and crypto payments with guaranteed USD settlement and no price volatility risk

The original crypto payment processor, processing over $1B annually. If your business wants to accept crypto payments but settle in USD (no crypto volatility on your balance sheet), BitPay converts crypto to fiat instantly at the point of sale.

$1B+ VolumeSince 2011Instant FiatMastercard Card
Provider intelligence

BitPay has been processing crypto payments since 2011, making them the most established crypto payment processor. Their core value: businesses accept crypto, but BitPay instantly converts to fiat and deposits USD/EUR into the business bank account. The merchant never touches crypto. They also issue the BitPay Card (Mastercard) that lets consumers spend crypto anywhere Mastercard is accepted. For established businesses adding crypto payment acceptance without changing their treasury management, BitPay provides the zero-volatility bridge.

Best forAny institution, platform, or enterprise needing the most trusted, regulated stablecoin (USDC) for payments, settlement, or treasury

Issuer of USDC, the leading regulated stablecoin with $30B+ in circulation. If your tokenization project, payment platform, or treasury operation needs a stablecoin that regulators, banks, and institutions trust, USDC is the institutional default.

Conduit

Best forCrypto companies needing reliable banking rails for converting between crypto and fiat without getting de-banked

Provides banking rails specifically designed for crypto companies. If your crypto or tokenization business has been de-banked or struggles to maintain fiat banking relationships, Conduit provides reliable crypto-to-fiat rails that do not get shut down.

Crypto-FriendlyBanking RailsDe-Bank ProofFiat Access
Provider intelligence

The biggest operational risk for crypto companies is not hacks or regulation. It is losing banking access. Traditional banks routinely close accounts of crypto businesses.

Immersve

Best forDeFi protocols and Web3 platforms wanting to issue branded Mastercard debit cards that spend directly from on-chain wallets

Web3-native card issuance: Mastercard debit cards that spend directly from on-chain wallets and DeFi positions. If your protocol or platform wants to give users a physical or virtual card that draws from their on-chain balance, Immersve provides the Web3-to-Mastercard bridge.

Web3 CardsOn-Chain SpendingMastercardProtocol Branded
Provider intelligence

Immersve takes a Web3-native approach to card issuance. Instead of requiring users to off-ramp crypto to a bank account and then spend via a traditional card, Immersve cards draw directly from on-chain wallets. Users can spend their USDC, stablecoin yields, or DeFi positions anywhere Mastercard is accepted. For DeFi protocols wanting to give their users real-world spending power without forcing off-ramp friction, Immersve provides the on-chain-to-card infrastructure.

MetaMask Institutional

Best forInstitutional investors and funds needing compliant DeFi access through the most widely used Web3 wallet with custody integration

Institutional version of MetaMask (the most used Web3 wallet, 30M+ users). If your fund or institution needs to access DeFi protocols with institutional compliance, reporting, and custody integration, MetaMask Institutional provides the compliant DeFi gateway.

MoneyGram

Best forProjects needing crypto-to-cash and cash-to-crypto conversion through 350,000+ physical agent locations worldwide

Global remittance network with 350,000+ agent locations now bridging to crypto. If your tokenization project needs to reach unbanked or cash-dependent populations who cannot use bank wire or ACH, MoneyGram provides the physical cash-to-crypto bridge.

350K+ Agents200+ CountriesCash-to-CryptoLast Mile
Provider intelligence

MoneyGram operates 350,000+ physical agent locations in 200+ countries. Their crypto integration means users can walk into a MoneyGram location, hand over cash, and receive stablecoins in their digital wallet (and vice versa). This is critical for tokenized asset projects targeting emerging markets where banking penetration is low. While digital-only on-ramps serve banked populations, MoneyGram serves the billions of people who transact primarily in cash. For tokenization projects with inclusive access mandates, MoneyGram provides the last-mile physical distribution.

13 / Stablecoin B2B Payments

Mural

Best forCompanies wanting to pay global contractors, vendors, and teams in stablecoins with automatic fiat conversion at the recipient end

Stablecoin-powered B2B payments for paying contractors, vendors, and teams globally. If your company pays international contractors and wants to use stablecoins to avoid wire fees and delays (while recipients still receive local fiat), Mural handles the conversion.

B2B StablecoinGlobal PayrollContractor PaymentsSame-Day
Provider intelligence

Mural targets a specific pain point: paying international contractors and vendors. Traditional wire transfers cost $25-50 per transaction, take 2-5 days, and have unpredictable FX rates. Mural uses stablecoins as the transfer rail: the sender pays in USDC, and the recipient receives local fiat currency in their bank account. The cost is a fraction of wire fees, settlement is same-day, and FX rates are transparent. For Web3 companies with distributed global teams (which is most of them), Mural replaces the expensive and slow international wire process.

Accept 200+ cryptocurrencies with automatic conversion to your preferred coin or fiat. If your business wants the broadest crypto payment acceptance (not just Bitcoin and Ethereum but altcoins, memecoins, and niche tokens), NOWPayments supports more assets than any other payment gateway.

200+ TokensAuto-ConvertMulti-PluginBroadest Acceptance
Provider intelligence

NOWPayments differentiates by supporting 200+ cryptocurrencies for payment acceptance, far more than competitors who typically support 10-20. They provide multiple integration options: API, e-commerce plugins (Shopify, WooCommerce, Magento), invoicing, donation widgets, and point-of-sale. Automatic conversion means merchants receive their preferred stablecoin or fiat regardless of which crypto the customer pays with. For businesses in the crypto ecosystem where customers hold diverse token portfolios, NOWPayments ensures no payment is turned away due to token incompatibility.

Full-stack enterprise payment technology supporting both traditional and crypto payments. If you are a large merchant or platform that needs one payment processor for cards, APMs, and crypto (not three separate integrations), Nuvei provides the unified enterprise platform.

Public Company$200B+ VolumeFull-StackEnterprise
Provider intelligence

Nuvei is a publicly traded (NASDAQ) payment technology company processing $200B+ annually. They added crypto capabilities alongside their traditional payment processing, meaning large merchants can accept credit cards, alternative payment methods, and cryptocurrency through a single integration. For enterprise merchants where crypto is one payment option among many (not the only one), Nuvei avoids the need for a separate crypto payment integration. The platform also supports instant crypto settlements, payouts, and crypto-to-fiat conversion.

Onramp

Best forCrypto platforms needing fiat on/off ramps in India, Turkey, Brazil, and other emerging markets where global providers have limited coverage

Fiat on/off ramp focused on emerging markets including India, Turkey, Brazil, Nigeria, and Southeast Asia. If your platform has users in emerging markets where MoonPay or Ramp coverage is limited, Onramp provides the local payment method integration that global providers miss.

Emerging MarketsIndia + BrazilLocal PaymentsGap Filler
Provider intelligence

Global on-ramp providers (MoonPay, Transak, Ramp) are strong in the US and Europe but often have limited coverage in emerging markets. Onramp fills this gap by integrating local payment methods in India (UPI, IMPS), Turkey, Brazil (PIX), Nigeria, and Southeast Asian countries. For crypto platforms with significant emerging market user bases, Onramp provides the local fiat rails that enable users in these countries to buy and sell crypto using their preferred local payment methods.

17 / Consumer Payment Giant + Stablecoin

PayPal (PYUSD)

Best forAny platform or institution wanting stablecoin payments backed by the most trusted consumer payment brand with 400M+ users

PayPal's stablecoin (PYUSD) brings institutional credibility and 400M+ user reach to stablecoin payments. If your tokenization or payment project needs a stablecoin with consumer brand recognition that your users already trust, PYUSD provides the familiarity that USDC and USDT cannot match.

400M+ UsersPYUSD StablecoinPaxos BackedMainstream
Provider intelligence

PayPal launched PYUSD, a fully-backed stablecoin issued by Paxos Trust. The significance: PayPal has 400M+ active accounts. PYUSD is available within the PayPal and Venmo apps, meaning mainstream consumers can use stablecoins without knowing what a blockchain is. For tokenization projects targeting mainstream (non-crypto-native) investors, PYUSD provides a stablecoin payment option within an interface these investors already use and trust. The PayPal brand eliminates the adoption barrier that USDC and USDT face with mainstream users.

Ripple provides a blockchain-based payment network used by 100+ banks and financial institutions for cross-border settlement. Where SWIFT takes 2-5 days and multiple correspondent banks, Ripple settles in seconds with pre-funded liquidity pools. The network uses either direct settlement (RippleNet) or on-demand liquidity using XRP as a bridge asset. For banks and payment providers serving corridors with slow or expensive SWIFT settlement, Ripple provides the faster, cheaper alternative. This is institutional infrastructure, not consumer-facing.

Sardine

Best forCrypto on-ramps, exchanges, and NFT platforms needing fraud prevention specifically designed for crypto transaction patterns

Fraud prevention and compliance platform built specifically for crypto. If your on-ramp, exchange, or NFT platform faces high chargeback rates, fraud losses, or compliance challenges that generic fraud tools cannot handle, Sardine provides crypto-native fraud intelligence.

Traditional fraud prevention (Stripe Radar, Sift) was built for e-commerce, not crypto. Crypto fraud patterns are different: wallet draining, bridge exploits, wash trading, mule wallets, identity farming. Sardine was built specifically for these crypto fraud patterns. They provide device intelligence, behavioral biometrics, and blockchain analytics to detect fraud before transactions are approved. For on-ramps and exchanges where fraud losses and chargebacks are the biggest threat to unit economics, Sardine's crypto-native fraud prevention directly improves profitability.

Solana Pay is an open payment protocol on Solana. Transactions settle in 400 milliseconds and cost fractions of a penny. Unlike card networks (2-3% fees, 2-day settlement) or even other blockchain payments (Ethereum gas fees), Solana Pay is essentially free and instant. Integrated with Shopify, merchants can accept USDC on Solana at checkout. For commerce platforms on Solana and merchants wanting the fastest, cheapest payment rail available, Solana Pay provides the infrastructure. The limitation: it is Solana-only.

STRIDE addresses a gap that generic payment processors and crypto on-ramps do not fill: the specific payment flows of tokenized real-world assets.

Generic payment rails handle none of these RWA-specific flows. STRIDE provides the payment infrastructure layer purpose-built for the tokenization economy.

For the millions of businesses already on Stripe, adding crypto payment capabilities is a configuration change, not a new integration. This is the most significant crypto payment development because it brings crypto to Stripe's massive existing merchant base.

Wyre was one of the early crypto payment API providers, offering simple fiat-to-crypto conversion for platforms. After being acquired, most of their platform customers migrated to competing providers. Wyre is included here as a historical reference because many tokenization platforms originally built their fiat on-ramp on Wyre APIs and need to understand the migration landscape. The leading alternatives are MoonPay (broadest platform integration), Transak (broadest country coverage), and Ramp (strongest in Europe).

Transparent international money transfer with real exchange rates and low fees. If your crypto or tokenization company needs to move fiat internationally with transparent FX rates (not the hidden markups of traditional banks), Wise provides the honest fiat transfer layer.

Transparent FXMid-Market RatesAPIGlobal Transfers
Provider intelligence

Wise is not a crypto company. It is included because it solves a critical pain point for crypto and tokenization companies: moving fiat internationally. When a tokenization platform needs to distribute dividends to international investors, pay global contractors, or fund operations across countries, Wise provides transparent FX (mid-market rates, no markup) and low fees (0.3-0.5% vs 3-5% at banks). For the fiat side of tokenization operations, Wise is often the most cost-effective transfer solution. Their API enables automated international payouts.

Provider intelligence

Zero Hash provides the invisible crypto infrastructure behind platforms you already know. When a fintech app lets you buy Bitcoin, a rewards program offers crypto cashback, or a payroll platform enables crypto paychecks, Zero Hash is often the infrastructure provider behind the scenes. They handle everything: settlement, custody, regulatory compliance, and tax reporting. The platform never needs to interact with blockchain directly. For fintechs and platforms wanting 'crypto as a feature' rather than building a crypto product, Zero Hash provides the regulated, white-label infrastructure.

Selection framework

How to evaluate payment infrastructure.

01

Start with the user journey

Mainstream consumers need simple fiat ramps, institutions need compliant settlement, and merchants need reliable conversion and reconciliation.

02

Map geography and payment methods

Coverage varies by country, local banking method, cards, wires, mobile wallets, cash networks and regulatory licenses.

03

Choose the right stablecoin layer

USDC, PYUSD, USDT, branded stablecoins and settlement APIs each create different compliance, treasury and liquidity considerations.

04

Check fraud and operations

Chargebacks, sanctions checks, KYC, wallet screening, treasury controls, reconciliation and support quality matter once payments go live.

FAQ
