What is USDT ERC20?
USDT ERC20 is Tether's dollar stablecoin issued as an ERC20 token on 
Ethereum, the same network that runs Ethereum (ETH). Its addresses, wallets and fees are all Ethereum's.
Other blockchains carry their own Tether, and none of them can see the others: coins on Ethereum will not appear on 
TRON or 
BNB Smart Chain. Exchangers can also quote a different hryvnia rate for each network, so sell USDT ERC20 through a direction made for this one.
Why do you need ETH to move USDT ERC20?
Because the network fee, called gas, is paid in ETH. Gas rises and falls with Ethereum's load and usually costs more than a transfer on TRON.
So keep some ETH on the same address that holds your USDT ERC20. Your wallet shows a gas estimate before you confirm — read it first. When the network is congested, a small transfer may be worth postponing.
The table lines USDT ERC20 up against two other Tether networks that exchangers quote for hryvnia. Watch the address column: that is where mistakes happen.
| Network | Address starts with | Fee paid in | How to tell it apart |
|---|---|---|---|
| USDT ERC20 (Ethereum) | 0x | ETH, depends on load | by the network name only |
| USDT BEP20 (BNB Smart Chain) | 0x | BNB | by the network name only |
| USDT TRC20 (TRON) | T | TRX or energy | by the T at the start of the address |
Ethereum and BNB Smart Chain addresses look identical, so the format will not warn you. If gas eats into the amounts you usually move, compare it with USDT TRC20 on TRON, where fees are paid in TRX.
How do you sell USDT ERC20 for hryvnias?
Find the direction for your bank on OnExchanger, create an order with the exchanger and send USDT ERC20 on Ethereum to the address in the order. After network confirmations, the exchanger pays hryvnias to your card or account.
For a card payout, the steps go in this order:
- Choose your bank, say USDT ERC20 to
Oschadbank or USDT ERC20 to a 
PUMB card. - Enter your amount and see how many hryvnias each exchanger pays.
- Go to the exchanger, add your card and create the order.
- Make sure the wallet has ETH for gas, select Ethereum and send to the address from the order.
- Wait for Ethereum confirmations and the payout.
Other banks are covered by USDT ERC20 to a UAH card. Some exchangers run AML/KYC checks or ask you to verify the card, and the name on it may need to match the order. That is the exchanger's requirement, not OnExchanger's.
Buying is the reverse: you pay by card or bank transfer, and the exchanger sends USDT ERC20 to the address you provide. Copy it from a wallet that works with Ethereum.
How do you avoid mixing up USDT ERC20 and BEP20?
Check the network name, not the address. Ethereum and BNB Smart Chain both use addresses starting with 0x, so a wallet will accept either. If the order expects USDT ERC20 and you send on BNB Smart Chain, the coins can be lost or need a manual recovery the exchanger cannot promise.
An address that starts with 0x does not mean
Three checks take less time than a support ticket:
- the exchanger's order says ERC20 or Ethereum;
- your wallet is sending on Ethereum, not BNB Smart Chain or BSC;
- the same address holds ETH for gas.
When a wallet offers several networks for USDT, do not trust the default — set it yourself.
How do you find a good USDT ERC20 offer on OnExchanger?
Look at the hryvnias you get for your amount of USDT ERC20; the direction table works that out with each exchanger's limits and reserve. Rates arrive from exchangers' public XML rate files, and OnExchanger only shows offers updated recently.
One exchanger may price ERC20 differently from TRC20, so compare within your network. To buy tether on Ethereum with another coin, try 
Bitcoin to USDT ERC20. Not sure which network suits you? Read TRC20, ERC20 and BEP20 compared.
OnExchanger only compares offers and never holds your money; the exchanger runs the swap, sets its rules and makes the payout. We may earn a partner commission when you go to an exchanger, yet you pay the exchanger's rate with nothing added by OnExchanger.
FAQ
No. Gas for a USDT ERC20 transfer is paid in ETH, so the transaction will not go through without it; top up the same address with a little ETH.
