Choosing a cryptocurrency payment gateway is one of those decisions where the marketing materials tell you very little about how your money actually moves. The real questions are technical and operational: does the gateway hold your funds between payment and settlement, which networks does it support for stablecoins, what are the total fees including hidden withdrawal costs, and do your customers need to complete identity verification at checkout?
This guide compares the leading platforms on those criteria. Whether you run an e-commerce store, a SaaS business, or sell digital products, understanding custody models, fee structures, and integration options will save you from unexpected costs and checkout friction down the line. For merchants evaluating their options across multiple providers, cryptocurrency payment gateways merchants offer a starting point for comparing features and pricing side by side.
Custody Models Explained
The single most important distinction between payment gateways is whether they are custodial or non-custodial. In a custodial model, customer payments first go to the gateway’s wallet. The gateway then settles the funds into your account according to its own schedule. You are relying on their systems, their security, and their continued operation. If their platform experiences downtime or your account faces a compliance review, your money is out of your control.
Non-custodial gateways work differently. Receiving addresses are derived from the merchant’s own wallet, typically using an extended public key. When a customer pays, funds land directly in the merchant’s wallet. The gateway monitors the blockchain, confirms receipt, and triggers a webhook. No transfer from the gateway to the merchant occurs because the money was never the gateway’s to transfer. This eliminates counterparty risk and removes withdrawal fees entirely.
Some platforms describe themselves as non-custodial while still routing payments through their own deposit address before forwarding them to the merchant. Technically, this means the gateway temporarily takes custody of the payment during that window. The distinction matters for both fee calculations and risk exposure.
Top Gateways Ranked
NOWPayments — Best for Coin Variety
NOWPayments lists over 350 cryptocurrencies, making it the widest asset supporter among hosted gateways. It works well for developers who prefer API-first architecture and have good documentation support. The service is particularly useful for merchants who genuinely need support for less common altcoins beyond the major five assets.
However, there is a structural detail worth understanding. When a customer pays, the receiving address belongs to NOWPayments, not the merchant. The gateway then forwards the funds to the merchant’s payout wallet. This introduces two practical considerations. First, a second network fee applies to the payout transaction on top of the customer’s original deposit — noticeable on Ethereum where gas costs can be high. Second, until that payout completes, the funds are under NOWPayments’ control rather than the merchant’s.
The service fee sits at 1% per transaction, or 1.5% for multi-currency and fixed-rate payments. Integration options include API access and plugins for major platforms.
Coinbase Business — US and Singapore Focused
Coinbase Commerce transitioned to Coinbase Business, a custodial, stablecoin-first platform available to businesses in the United States and Singapore. The unified product combines custody, bank off-ramp, invoicing, and accounting integrations into a single account.
The main limitation is geographic availability. Merchants outside those countries had to move to alternative providers. The platform currently supports USDC only, with plans to add USDT. Transaction fees are 1% for migrating merchants, though this may increase for new signups. Brand recognition provides some customer trust at checkout, but platform dependency means account freezes or compliance reviews directly affect fund access.
BitPay — Enterprise-First Approach
Founded in 2011, BitPay has the longest operational track record in crypto payment processing. The platform supports over 100 cryptocurrencies and maintains strong relationships with enterprise clients. Its compliance infrastructure is mature and recognized by larger organizations.
BitPay operates on a custodial model with published rates of 2% plus 25 cents per transaction for merchants processing under $500,000 monthly. Higher volumes receive lower rates. A significant drawback is the checkout experience: BitPay requires customers to log in or create a BitPay account and complete identity verification before paying an invoice. That extra step creates friction that can reduce conversion rates.
BTCPay Server — Self-Hosted Zero-Fee Option
BTCPay Server is free, open-source software that you run on your own server. There is no company in the payment flow, no percentage fee, and no account that can be suspended. Funds go directly to your wallet with zero transaction fees beyond blockchain network costs.
The trade-off is technical responsibility. You handle server deployment, maintenance, updates, and support. Monthly hosting runs approximately $5 – 20 on a VPS. Bitcoin and Lightning Network support are strong out of the box, but altcoin and stablecoin configuration requires additional setup. WooCommerce and Shopify integrations are available.
Cryptomus — Budget Option for High Volume
Cryptomus supports 100+ cryptocurrencies with fees starting at 2% for new users and potentially reducible to 0.4% through negotiation. It offers API access for custom integrations and reasonable documentation.
The custody model is not clearly disclosed, which merchants should verify before committing. Support infrastructure and operational track record are less proven than larger competitors. The integration ecosystem is narrower compared to more established players.
Fee Structures Compared
| Gateway | Base Fee | Withdrawal Fees | Network Fees | Total on $100 TRC-20 |
|---|---|---|---|---|
| NOWPayments | 1% | Network fee on payout | Customer pays deposit | ~$1.20 –$1.50 |
| Coinbase Business | 1% | Yes | Included | ~$1.00 |
| BitPay | 2% + 25¢ | Yes | Included | ~$3.25 |
| BTCPay Server | 0% | None | Blockchain only | ~$0.20 –$0.50 |
| Cryptomus | 2% | Unclear | Unclear | ~$2.00+ |
| Paymento | 0.5% | None (own wallet) | None (own wallet) | ~$0.70 |
Fee transparency varies significantly across providers. Gateway percentage fees are easy to find, but withdrawal fees, forwarding fees, and conversion costs are often buried. On a connect-your-own-wallet gateway, there is no withdrawal step because funds go directly to the merchant’s wallet from the moment of payment. Platforms that route payments through their own deposit address incur a second network fee on the payout, which compounds over transaction volume.
Integration Ecosystem
Platform compatibility determines whether a gateway fits your existing setup without requiring a rebuild. WooCommerce has the broadest plugin support across multiple providers. WHMCS adoption is limited — most enterprise-focused gateways ignore the hosting management platform entirely. Shopify native integrations remain sparse, with many providers offering only API-based connections.
Payment links provide a universal option for merchants without websites, accepting payments through hosted checkout pages. REST APIs enable custom integrations for platforms that lack dedicated plugins. Some gateways also offer Telegram automation, granting member access automatically upon payment confirmation — useful for community monetization.
Choosing the Right Gateway
Your ideal gateway depends on your specific situation. WooCommerce store owners benefit from providers with native plugins and non-custodial settlement. WHMCS users have fewer options, making careful selection critical. International merchants serving Asia, Middle East, Eastern Europe, or Latin America should prioritize multi-chain USDT support across Ethereum, Solana, and Tron networks.
Merchants needing extensive altcoin coverage should look toward platforms with the widest asset lists, accepting the structural trade-offs that come with those models. Privacy-focused businesses selling digital content or security tools benefit from optional payer email, allowing transactions without personal data submission.
Enterprise organizations with compliance-heavy requirements should weigh brand recognition against custody risk. Businesses running subscription communities or Telegram groups should evaluate automation capabilities alongside payment processing features.
Before committing to any provider, ask directly how receiving addresses are generated, what the total cost is on a typical transaction including all fees, whether payers must submit personal information, and what happens to funds during platform downtime. The answers reveal your actual risk exposure far better than marketing descriptions.
