Choosing the right payment gateway for accepting USDT is one of the most critical decisions for any crypto-forward business. The landscape has shifted dramatically since Tether expanded beyond Ethereum, and merchants now need to evaluate processing fees, supported networks, settlement speed, and regulatory standing before committing to a provider. This guide compares three major options — NOWPayments, CoinGate, and Cryptomus — across the dimensions that directly impact your bottom line. For businesses evaluating these providers, understanding usdt payment gateway coingate cryptomus fees helps clarify which option aligns with your operational needs.
Understanding USDT Payment Processing Costs
Every crypto payment gateway charges more than just a headline percentage. When evaluating total cost, you need to account for the processing fee, blockchain network gas costs, conversion margins, withdrawal charges, and any hidden risk premiums. A provider advertising 0.5% can end up costing significantly more than a competitor at 1% once network fees and conversion layers are included.
Small-order merchants feel network fees most acutely — a $25 invoice on TRC20 might lose 17% to gas alone during peak periods. Understanding which networks each gateway supports and what those networks cost is essential for accurate budgeting.
NOWPayments: Broad Coverage With Competitive Rates
NOWPayments stands out for its sheer breadth of supported assets — over 350 cryptocurrencies and 40 fiat currencies. For merchants who need USDT acceptance alongside a wide altcoin offering, it remains one of the most flexible options available.
Transaction Fees
NOWPayments uses a tiered rate structure based on transaction type. Single-currency payments carry a base rate of 0.5%, though this requires completing identity and business verification. When an exchange is involved — meaning the customer pays in one cryptocurrency and the merchant settles in another — the rate rises to 1%. Fixed-rate mode runs at 1.5%. There are no setup fees and no monthly subscription charges.
USDT Network Support
| Network | Symbol | Typical Gas Cost | Speed |
|---|---|---|---|
| Tron | TRC20 | $0 –$1 | Fast |
| BNB Smart Chain | BEP20 | $0.10 –$0.50 | Fast |
| Ethereum | ERC20 | $0.50 –$5+ | Variable |
| Solana | SPL | <$0.01 | Very fast |
| Polygon | MATIC | <$0.01 | Very fast |
New partners receive zero network fees on USDT TRC20 deposits for the first two months, providing meaningful savings during initial integration phases.
Settlement and Control
NOWPayments operates primarily in custodial mode for new accounts but offers a non-custodial payout flow where payments forward directly to your personal wallet. Withdrawals to external addresses carry no service fee from NOWPayments. The platform also supports auto-conversion, allowing customers to pay in any supported coin while you receive stablecoin settlement.
Important limitation: NOWPayments’ terms exclude residents and citizens of the European Union, United Kingdom, United States, UAE, and Russia.
CoinGate: Regulated EU Option Without USDT
CoinGate carries proper licensing under the EU’s MiCA framework through authorization by the Bank of Lithuania, making it one of the few crypto payment processors genuinely available to European businesses. However, its asset selection creates a fundamental problem for USDT-focused merchants.
Transaction Fees
CoinGate charges a flat 1% fee for all crypto transactions with no setup or monthly costs. The effective cost includes an unpublished risk margin added to exchange rates. On a $10,000 monthly volume, you should budget at least $100 in processing fees plus whatever the risk margin adds.
The USDT Problem
CoinGate does not accept USDT. Its stablecoin offerings consist solely of USDC across seven networks — Ethereum, BNB Smart Chain, Solana, Polygon, Arbitrum, Base, and Optimism — and EURC on Ethereum. Merchants whose customer base expects Tether payments must either integrate a secondary gateway or redirect those customers elsewhere.
Fiat Settlement Advantage
Where CoinGate excels is fiat off-ramping. SEPA withdrawals are free with a €50 minimum, and SWIFT transfers to USD or GBP incur a 0.5% fee with a €50 minimum. Weekly settlement schedules keep funds moving predictably. Bitcoin Lightning Network is enabled by default on plugin installations.
Integration Ecosystem
CoinGate offers plugins for WooCommerce, Magento 2, PrestaShop, WIX, WHMCS, and OpenCart. The platform maintains full regulatory compliance for businesses operating under EU financial frameworks.
Cryptomus: Volume-Based Pricing With Full USDT Support
Cryptomus positions itself around customization and user experience, offering a white-label checkout and broad e-commerce integrations. Its pricing model rewards high-volume merchants but starts steeply for new accounts.
Transaction Fees
Cryptomus advertises a range from 0.4% to 2%, with new merchants starting at the 2% tier. High-volume operators can negotiate rates approaching 0.4%. If you process fiat-to-crypto conversions through the gateway, an additional 3.9% stacking fee applies. Withdrawals carry no Cryptomus commission, though standard blockchain network gas fees still apply.
USDT Network Support
Cryptomus supports USDT across eight networks, the widest list among the three gateways. This breadth accommodates customers using any major chain without requiring separate integration paths. The platform also supports USDC alongside USDT, giving merchants flexibility in stablecoin settlement.
Custody and Compliance
Cryptomus operates a fully custodial business wallet model. KYC is mandatory for all users, and the terms explicitly state the service does not serve U.S. citizens or residents. Auto-charging for recurring payments works only if both the merchant and payer maintain Cryptomus accounts.

Which Gateway Fits Your Business?
The answer depends on three factors: your jurisdiction, your customer base’s preferred networks, and your expected monthly volume.
If you operate outside restricted markets and need maximum coin diversity with competitive USDT fees, NOWPayments delivers the lowest headline rates and broadest network coverage. The 0.5% single-currency rate is the cheapest published option, and the non-custodial payout path gives you direct control over settled funds.
If you’re based in the EU and need regulated settlement with fiat off-ramping, CoinGate is the compliant choice — but you must accept USDC instead of USDT. This may be acceptable if your customers are comfortable with alternative stablecoins, but it eliminates USDT entirely from your checkout.
If you prioritize USDT network variety and can absorb higher starting fees, Cryptomus offers the most comprehensive multi-chain USDT support with negotiable rates that improve as volume grows. The 2% starting rate makes it less attractive for low-volume operations, but merchants processing over $50,000 monthly can push rates toward the 0.4% floor through negotiation.
