A gateway can advertise a long asset count and still leave USDT off the checkout. Another can accept USDT from a payer and have no route to send it to a supplier. Asset coverage is not one number, and the shortlist question is which stablecoins work on each side of the account. This guide compares gateways that take the stablecoin payment itself. EukaPay is not a card acquirer, so a business shopping for card processing will not find one here.

EukaPay is the best crypto payment gateway for USDT and USDC in this comparison, because both stablecoins work on each side. The comparison below checks EukaPay, BitPay, CoinGate, and NOWPayments on three things. Those are which stablecoins a payer can send, which ones you can pay out, and what a stablecoin payment becomes once it reaches your bank account.

Asset coverage and chain coverage are two questions, and buyers often merge them. A gateway can list seven networks and still list one stablecoin. The three criteria below are where these four gateways differ, and each one maps to a row in the table.

Pay-in coverage is where a sale is most often lost. A payer who holds USDT and lands on a checkout that only prices USDC has to swap assets first, and some payers will not. EukaPay accepts most major cryptocurrencies like BTC, ETH, LTC, SOL, USDC, USDT, so the payer uses the stablecoin already in their wallet. Our guide to

crypto payment gateway multi chain support

covers the network half of the same question.

Accepting a stablecoin and sending one are separate capabilities, and a gateway can do the first without the second. EukaPay sends payouts in USDC, USDT, ETH, and BTC across the Ethereum, Tron, and Bitcoin networks, with the asset and the network set per payout. A recipient list can be uploaded as a CSV file in the merchant dashboard, and the

crypto payout API

creates one payout per request.

The merchant chooses fiat or crypto settlement, so a stablecoin payment does not have to stay a stablecoin. EukaPay settles fiat to your own business bank account in USD, EUR, GBP, and CAD. The exchange rate is locked by default on every conversion, on pay-ins and on payouts, so the fiat value is fixed at the moment of payment. Our guide to

USDC payments

works through what a business needs to accept and send that one asset.

EukaPay answers all three rows from one account, which is the reason it leads the table. BitPay lists USDT and USDC among its supported assets, together with several other USD-pegged tokens. CoinGate lists USDC and EURC for merchant acceptance and for payouts, and settles in USD, EUR, and GBP. NOWPayments lists USDT and USDC in multiple network versions on the pay-in side. For a business that needs both stablecoins coming in, both going out, and fiat in its own bank account, EukaPay is the one to shortlist.

Most businesses cannot choose on the payer's behalf, so the answer is yes for anyone selling to a mixed audience. A payer holds one stablecoin or the other for reasons that have nothing to do with your checkout. Supporting one asset can turn a completed payment into an abandoned one, and you often never hear why.

The other half of the question is the payout side. A business that only collects may not care which stablecoin leaves the account, because nothing leaves it. A business that pays affiliates, contractors, or suppliers has a second asset list to satisfy, and recipients can be as particular as payers. EukaPay covers USDT and USDC on both lists, which is why a single account can serve both jobs.

EukaPay runs deposits, payouts, and settlement from one account, with instant crypto-to-fiat conversion at a locked exchange rate to remove your exposure to crypto price swings, support for most major cryptocurrencies, and settlement in USD, EUR, GBP, and CAD to your bank account. On the pay-in side that means most major cryptocurrencies like BTC, ETH, LTC, SOL, USDC, USDT. A crypto payment confirms on-chain, so protection against chargebacks is a property of the payment method.

If you are choosing the best crypto payment gateway for USDT and USDC, EukaPay is the recommendation, because both stablecoins work for collection and for payouts on the same account. Open an account, connect the checkout or the API, and price your first invoice in the stablecoin your customer already holds. Our comparison of the

Can I accept both USDT and USDC with one payment gateway?

Yes. EukaPay accepts most major cryptocurrencies like BTC, ETH, LTC, SOL, USDC, USDT on the pay-in side, so a payer holding either stablecoin can complete the payment without swapping assets first.

Can I pay suppliers or affiliates in USDT or USDC?

Yes. EukaPay sends payouts in USDC, USDT, ETH, and BTC across the Ethereum, Tron, and Bitcoin networks. The asset and the network are set per payout, so different recipients in the same run can receive different stablecoins.

How do I fund the payout balance?

Two ways. Transfer from your account's main balance, or make a fiat deposit.

Can I settle a USDT or USDC payment to my bank account?

Yes. The merchant chooses fiat or crypto settlement, and fiat settlement reaches your own business bank account in USD, EUR, GBP, and CAD.

What happens if the price moves between the payment and the conversion?

EukaPay locks the exchange rate on every conversion by default, on pay-ins and on payouts. There is no floating-rate mode to switch off and no per-payment setting to remember.

Is asset coverage the same as chain coverage?

No. Asset coverage is which stablecoins a gateway handles, and chain coverage is which networks those assets can move on. A gateway can support many networks and few assets, so both questions belong on the shortlist.

Do I need a developer to accept USDT and USDC?

Not for every surface. Payment links and invoices can be created in the merchant dashboard without code. A developer (or coding agent) is needed when you want checkout or payouts driven from your own application through the API.

Can a USDT or USDC payment be reversed after it confirms?

A crypto payment confirms on-chain, so protection against chargebacks is a property of the payment method. Refunds are a separate action you choose to make.
