How to accept USDT payments in 2026
August 04, 2026
USDT is the largest stablecoin in circulation and the token most business buyers reach for when they pay in digital assets. It holds a one-to-one peg to the US dollar, so a $2,400 invoice is paid with 2,400 USDT and neither side watches a price chart.
For a merchant deciding to accept USDT payments, the real decision is not whether to take stablecoins or crypto. It is which network to take them on. EukaPay supports USDT on Ethereum as an ERC-20 token and on Tron as a TRC-20 token, and the two differ on settlement speed and on where they are used. This guide covers where USDT stands, how each network behaves, and the steps to start collecting.
In this guide, you'll learn:
Where USDT stands in August 2026 by price, market capitalisation, and rank
How ERC-20 and TRC-20 compare on settlement speed and regional use
Which network suits an in-person counter and which suits an invoice
How to accept USDT payments through a checkout, an invoice, or an API
What USDT is
USDT is a dollar-pegged stablecoin issued by Tether. Each token is intended to trade at $1.00 and is backed by Tether's reserves. Tether mints USDT when buyers deposit dollars and redeems it when holders return tokens, and that redemption mechanism anchors the market price. The peg holds closely but not perfectly, and USDT trades a fraction below $1.00 at times.
USDT is not a blockchain of its own. It is a token contract deployed on several blockchains, so the same dollar-pegged unit moves across networks with different confirmation rules. USDT sent on Tron is not interchangeable with USDT sent on Ethereum, which is why a merchant publishes a network alongside a wallet address.
Where USDT stands today
The figures below are a snapshot, so treat them as context rather than a forecast.
Metric | Value (August 4, 2026) |
|---|---|
Price | $0.9986 |
Market capitalisation | $183.2 billion |
Rank by market cap | 3 |
Circulating supply | ~183.4 billion USDT |
Issuer | Tether |
At $183.2 billion, USDT is the largest stablecoin by a wide margin and the third-largest digital asset by market capitalisation. Its price of $0.9986 sits essentially at the $1.00 peg. That float matters commercially, because USDT is the token most crypto-holding buyers keep for spending rather than investment.
Why customers pay with USDT
Three reasons come up repeatedly.
Price stability - the customer carries no exposure either
A dollar-pegged stablecoin removes price exposure for the customer, not just for the merchant. A buyer paying in BTC weighs spending an asset that might be worth more next month. A buyer paying in USDT is spending dollars. That asymmetry is why stablecoins dominate merchant crypto volume.
Cross-border reach - dollars without correspondent banking
A customer in Dubai, Jakarta, or Warsaw sends USDT with no FX quote, no intermediary bank, and no cut-off time. For businesses invoicing internationally, USDT frequently completes a payment a wire would delay by days.
Finality - no chargebacks
A confirmed USDT transfer cannot be reversed by the sender or their bank. For sectors carrying high dispute rates, that property is the whole argument. Our guide to choosing a
covers where the protection begins and ends.
Which network should you accept USDT on?
EukaPay supports USDT on two networks: Ethereum (ERC-20) and Tron (TRC-20). Both deliver the same dollar-pegged token, so the choice comes down to settlement speed and where your customers are.
USDT on Ethereum (ERC-20) | USDT on Tron (TRC-20) | |
|---|---|---|
Block time | A slot roughly every 12 seconds | A block roughly every 3 seconds |
Practical settlement | Finality in roughly 12.8 minutes, after two epochs | Solidified after 19 blocks, roughly 57 seconds |
Regional popularity | Broad, strongest among Western businesses | The more widely used USDT network worldwide, especially across Asia, the Middle East, and Eastern Europe |
Best for | Invoices where a 13-minute wait is acceptable, and merchants who also accept USDC on the same network | An in-person counter and time-sensitive payments |
TRC-20 is the more widely used network for USDT worldwide, so a customer in Asia, the Middle East, or Eastern Europe is the most likely to reach for it. Tron's roughly 57-second settlement suits an in-person counter and any payment where someone is standing at the till waiting. Ethereum suits invoices where a 13-minute wait is acceptable, and it is the same network USDC runs on, so a merchant accepting both stablecoins shares one integration. Most merchants enable both networks and let the customer pick.
Settlement speed
Tron produces a block roughly every 3 seconds, and a transaction is solidified after 19 blocks, or about 57 seconds. That is the number that matters at a counter, because it is how long the customer waits before the payment is settled.
Ethereum produces a slot roughly every 12 seconds and reaches finality in roughly 12.8 minutes, so a payment is visible within a minute but only irreversible after two epochs. Most merchants release low-value digital orders on the first confirmation and wait for finality on high-value ones. For an in-store counter, the 57-second Tron path is the practical one.

Choose your USDT networks.
Turn on Ethereum (ERC-20), Tron (TRC-20), or both. If your buyers sit in Asia, the Middle East, or Eastern Europe, TRC-20 will carry most volume.
Choose your settlement currency.

One platform underneath
Whichever network and channel you use, the same infrastructure sits beneath it: instant crypto-to-fiat conversion at a locked exchange rate to remove all crypto volatility, protection against chargebacks, support for a wide range of cryptocurrencies, and settlement in USD, EUR, GBP, CAD to your bank account.
Choosing between ERC-20 and TRC-20 is a question of fit rather than of one network being better. Tron delivers roughly one-minute settlement and the wider USDT user base. Ethereum settles in about 13 minutes and shares a network with USDC, so one integration covers both stablecoins. Most merchants accept both, because the customer decides which one arrives.

Frequently asked questions
Can I accept USDT payments without holding USDT?
Yes. EukaPay converts each payment at a locked exchange rate and settles USD, EUR, GBP, CAD to your bank account, so no USDT sits on your balance sheet.
Which USDT networks does EukaPay support?
Two: Ethereum (ERC-20) and Tron (TRC-20). Merchants choose one or both, and each enabled network appears at checkout.
Which USDT network should I publish on an invoice?
Publish the network your buyers actually use. TRC-20 is the more widely used USDT network worldwide, so it is the safer default for international buyers, while ERC-20 suits buyers who already hold USDC on Ethereum.
What happens if a customer sends USDT on the wrong network?
The transfer will not appear against your order, because USDT on Tron and USDT on Ethereum are separate tokens. Always show the network alongside the address at checkout, and contact support if a customer has already sent on an unsupported chain.
How long does a USDT payment take to settle?
On Tron, roughly 57 seconds, once the transaction is solidified after 19 blocks. On Ethereum, roughly 12.8 minutes.
What happens if USDT trades below its $1.00 peg during checkout?
The exchange rate is locked when the payment is created, so the amount you invoice is the amount you receive in your settlement currency.
Can I accept USDT on Solana through EukaPay?
No. EukaPay supports USDT on Ethereum and Tron only. Solana is supported for SOL payments, and USDC on Ethereum.
Does EukaPay charge monthly fees?
No. There are no monthly fees, and settlements are free.
