Choosing a crypto payment gateway for your online business comes down to two fundamental decisions: do you want funds routed directly to a wallet you control, or are you comfortable letting a third party handle the money on your behalf? The answer shapes everything — fees, setup time, supported coins, and risk exposure. This guide compares the major providers so you can make an informed choice.
When evaluating any crypto payment gateway providers, start by looking past marketing claims and examining the actual custody model, fee structure, and settlement path. These three factors determine your real cost of acceptance far more than brand recognition ever will.
How We Compared Gateways
The evaluation covers six dimensions that directly impact merchant operations: custody model (who holds the funds), supported cryptocurrencies, transaction fees, KYC requirements, fiat settlement availability, and platform integrations. Each provider is assessed on these criteria using publicly available information from their documentation and pricing pages.
The custody model deserves the most attention because it determines counterparty risk. When a gateway holds your funds — even briefly — those funds are exposed to operational failures, regulatory actions, or liquidity issues beyond your control. Non-custodial gateways route payments directly from customer to merchant wallet, eliminating that risk entirely.
Provider Overview
NOWPayments
NOWPayments supports over 350 cryptocurrencies, the widest selection among major providers. It operates a custodial model with auto-conversion features, meaning customers can pay in one coin while you receive another. The API is well-documented and developer-friendly, making it suitable for custom integrations.
Transaction fees sit at 1% for single-currency payments and 1.5% for multi-currency or fixed-rate options. NOWPayments has plugins for Shopify, WooCommerce, and several other platforms. KYC requirements apply above certain volume thresholds. As a custodial service, funds pass through NOWPayments during conversion and settlement — a trade-off worth considering against the broad coin support.
Aurpay
Aurpay uses a non-custodial architecture, routing payments directly to your wallet with no intermediary holding funds. It supports BTC, Bitcoin Lightning, ETH, USDT and USDC on ERC-20 and TRC-20 networks, DAI on ERC-20, and BNB. Transaction fees are 0.8% flat.
Onboarding requires no contracts, bank account setup, or identity verification — connect a wallet address and begin accepting payments. Integrations exist for Shopify (Custom App) and WooCommerce (dedicated plugin). The smaller brand presence compared to established names means fewer third-party reviews, but the custody guarantee and low fees appeal to merchants prioritizing control over familiarity.
BitPay
BitPay is the longest-operating crypto payment processor, running since 2011. It uses a custodial model: BitPay receives customer payments, converts them, and settles to your bank account in fiat. Full KYC is required including government ID and business verification.
Processing fees start at 2% plus $0.25 per transaction below $500,000 monthly volume, dropping to 1.5% and then 1% at higher tiers. Settlement to bank accounts takes one to two business days. BitPay’s strength lies in fiat settlement infrastructure and name recognition; its weakness is the custodial risk — funds remain under BitPay’s control during the entire settlement window.
CoinGate
CoinGate is a Lithuania-based provider focused on the European market. As of late 2026, it supports around 11 cryptocurrencies for merchant payments and settles in EUR via SEPA bank transfers. Processing fees are 1%.
KYC is required for all merchants. CoinGate offers plugins for WooCommerce, Magento, and PrestaShop, but lacks a native Shopify integration. European merchants benefit from fast local currency settlement, though international merchants outside Europe may find options limited.
BTCPay Server
BTCPay Server is open-source, self-hosted payment processing software offering complete sovereignty. You run your own server, hold your own keys, and pay zero processing fees. No KYC exists because there is no third party involved.
The trade-off is technical complexity. You need to deploy and maintain a full Bitcoin node and optionally a Lightning Network node. Support focuses primarily on Bitcoin with limited altcoin coverage through community plugins. There is no fiat settlement — conversions happen separately. Ideal for technically skilled merchants prioritizing maximum control.
Coinbase Business
Coinbase formerly offered a self-custodial Commerce product that most comparisons still reference. That product closed outside the United States and Singapore in March 2026, replaced by Coinbase Business, which is custodial. Business verification is required.
The service is only available to businesses in the US and Singapore. Merchants in other regions have no migration path. If you operate in those markets and prefer a familiar brand, it warrants consideration. Everyone else should look elsewhere.

Understanding Custody Models
The custody distinction is not abstract — it directly determines who bears risk when something goes wrong. In custodial models, the gateway receives your customer’s payment, holds it temporarily, then forwards it to you. During that holding period, funds face the gateway’s operational and security risks.
The industry has documented numerous cases where custodial processors froze merchant funds during regulatory disputes, delayed withdrawals during liquidity crunches, or lost assets to breaches. When using a custodial gateway, you trust a third party with revenue similarly to how you trust a bank — except crypto processors carry no deposit insurance.
Non-custodial gateways eliminate this risk category. Payments flow from customer wallet to merchant wallet. The gateway facilitates the transaction — generating payment requests, monitoring the blockchain, notifying your store — but never touches the funds. If the gateway went offline tomorrow, confirmed on-chain payments would remain secure in your wallet.
BTCPay Server extends this further by removing even the facilitating server from your trust model. You run everything yourself. The cost is operational complexity. Most e-commerce merchants find managed non-custodial options like Aurpay provide the same custody guarantee without DevOps overhead.
Platform Recommendations
Shopify Merchants
NOWPayments, Aurpay, and BitPay all offer Shopify integrations. Aurpay is the only non-custodial option with direct Shopify support. For fiat settlement, BitPay remains the most reliable choice.
WooCommerce Merchants
WooCommerce has the broadest gateway compatibility. All providers listed offer some form of WooCommerce integration. For non-custodial stablecoin payments, Aurpay provides a dedicated plugin alongside BTCPay Server for those comfortable with self-hosting.
Custom Checkout Builders
API quality matters most for headless commerce. NOWPayments and BTCPay Server offer the most comprehensive documentation. Aurpay and BitPay provide solid REST APIs for custom implementations.
Fee Structures Beyond Headline Rates
Published transaction fees tell only part of the story. Network fees accompany every on-chain transaction, paid by either customer or merchant. On Ethereum mainnet, these can reach several dollars during peak congestion. The assumption that Tron is always cheaper does not hold universally — network conditions fluctuate daily.
Conversion fees matter significantly for custodial gateways. Providers charging for multi-currency conversion add hidden costs not visible on pricing pages. With non-custodial settlement in stablecoins like USDT or USDC, no conversion fee applies because the assets are already dollar-denominated.
Withdrawal fees appear in custodial ecosystems when moving funds out of the platform balance. Non-custodial gateways have no withdrawal concept — funds arrive directly in your wallet.
Making Your Decision
Three questions narrow the field effectively:
Do you need fiat settlement? If yes, BitPay serves global merchants and CoinGate serves European merchants. If you can hold stablecoins, non-custodial options save both fees and risk.
How important is custody control? Past experience with exchange freezes or processor insolvencies makes non-custodial essential rather than optional. Aurpay and BTCPay Server are the primary options.
What is your technical capacity? Running a server and Bitcoin node enables BTCPay Server’s maximum sovereignty. Wanting non-custodial benefits without infrastructure points toward managed solutions.
Most merchants fall into two categories: those needing set-and-forget fiat settlement, and those preferring direct wallet settlement with no intermediary. Other providers fill specific niches — maximum coin variety, regional fiat rails, or full self-sovereignty.
