What USDT is
USDT is the US dollar stablecoin issued by Tether. Each token is pegged 1 to 1 to the dollar, and Tether says every token is backed by its reserves. It is issued on several blockchains, among them Ethereum, Tron, Solana and BNB Smart Chain.
It is one of the most used stablecoins, held and moved by crypto platforms, payment companies and their customers around the world. If you serve customers in the EU, involve your compliance team early: as of ESMA's register update of 30 September 2026, Tether is not listed as an e-money token issuer under MiCA. Our checkout module accepts USDT as one of its two stablecoins, next to USDC.
What it does in your platform
Checkout
Lets buyers pay in USDT from their own wallet, on the networks you accept. The module watches for the transfer, credits the merchant once it is confirmed and screened, and books it in the ledger in USDT.
How the connection works
USDT payments arrive on chain, at addresses from your custody setup: an institutional custody provider or your own keys. The module reads each network through your own nodes or a node provider.
The buyer picks USDT
On the merchant's hosted checkout, with the network they hold it on, for example Tron or Ethereum.
An address is shown
The checkout shows the amount in USDT and a payment address on that network, from your custody setup.
The buyer sends
They send the USDT from their own wallet or from an exchange account.
Confirmations count
The module sees the transfer on chain and waits for the number of confirmations you set for that network.
The transfer is screened
Like every incoming transfer on the platform, it is screened before it is credited.
The order is paid
The order is marked paid and the merchant's balance is credited in USDT in the ledger, ready to keep or to convert through the FX module.
Next to other payment methods
USDT and USDC are the checkout's two stablecoins, next to cards, wallets and bank payments. Buyers pick the coin and the network they hold, and the merchant sees one paid order either way.
The confirmation rules, the screening and the ledger belong to the platform, so the custody or node provider behind them can change without touching the checkout. Adding another EVM network is mostly configuration; other networks need a new connector.
When USDT fits best
A strong fit when
- Your merchants sell to buyers who hold USDT and want to pay with it directly.
- You sell across borders to buyers who already keep dollars on chain.
- Your buyers use networks such as Tron or Ethereum, which your custody setup already supports.
Also worth a look
- USDC, where you want a stablecoin whose EU issuer is authorised under MiCA.
- Cards and bank payments, for buyers who do not hold crypto.
How we get you live
The networks
We choose with you the networks you accept USDT on, among those Tether issues it on and your custody setup supports.
Custody and nodes
We connect your custody provider or your own keys, and node access for each network, so payment addresses and confirmations come from your setup.
The rules
We set the confirmations each network needs before an order counts as paid, and the screening every incoming transfer goes through.
A full test run
The whole flow runs on a test network first, with a test token standing in for USDT, then with a small real payment on each network you accept.
