Don't pick BSC (BEP20) when you send USDT from Binance to OKX
Why OKX won't take USDT sent over BSC (BEP20)
When you move USDT from Binance to OKX, the network has to be one of the options on OKX's USDT deposit page, and the Binance withdrawal has to use that same one. BSC (BEP20) is the option that doesn't work: OKX's Help Center, in the Important note shown in the October 2026 screenshot above, states that the platform does not currently support depositing USDT on the BSC network.
The network chosen for the withdrawal on the sending platform must match the network chosen for the deposit on OKX, and a mismatch may mean the coins are lost.
The names are the confusing part, because the two exchanges write the same chain differently. OKX treats BEP20, BSC and Binance Smart Chain as one network and calls it BNB Smart Chain. Binance's withdrawal fee page lists the chain as BNB Smart Chain (BEP20) in the column that names the network. So on Binance's withdrawal page, the option with BNB Smart Chain or BEP20 in its name is the chain OKX currently won't accept USDT on.
BSC isn't switched off entirely at OKX. The same help page says BNB deposits on the BSC network are still supported: on one chain, BNB deposits are supported and USDT deposits currently are not.
Which network to choose on Binance's withdrawal page
The list that decides this is on the OKX side. In the OKX app, go to Deposit crypto on the homepage and select USDT; the page then lists the deposit networks currently available for that coin. That list is the one to go by.
Then work from the Binance side: a network on Binance's withdrawal page that has no counterpart in OKX's USDT deposit list is one to leave alone.
| Chain | What OKX calls it | How Binance's withdrawal fee page writes it | Can OKX receive USDT on it? |
|---|---|---|---|
| BSC | BNB Smart Chain (BEP20, BSC and Binance Smart Chain all refer to it) | BNB Smart Chain (BEP20) | No; OKX does take BNB deposits on this chain |
| Ethereum | Ethereum (ERC20) | Ethereum (ERC20) | Yes — USDT-ERC20 was on OKX's withdrawal list in September 2026; confirm on your deposit page |
| Tron | Tron (TRC20) | Check the network list on Binance's withdrawal page | Yes — USDT-TRC20 was on OKX's withdrawal list in September 2026; confirm on your deposit page |
The BSC row follows OKX's help page as it read in October 2026. The networks open for USDT deposits are the ones your deposit page lists at the time you make the transfer.
With the names matched, it's worth one more check: where both pages show a USDT contract address for the network, compare the two before you submit.
TRC20 or ERC20: comparing the Binance withdrawal fee when both work
OKX's help page on choosing a network says networks differ in performance — speed, security and transaction fees all vary from one to the next. If your OKX deposit page lists both TRC20 and ERC20, either is a candidate.
The money is leaving Binance, so Binance charges the fee. Its withdrawal fee page says each withdrawal carries a flat fee, the amount depends on the network chosen, and the live rate is the one shown on the withdrawal page. A network's name won't tell you which is cheaper. On Binance's withdrawal page, select USDT, click through each of the networks OKX also accepts, and compare the fee shown for each before settling on one.
Withdrawing USDT from OKX to Binance is a separate topic, covered in the guide to OKX withdrawal times and fees.
What USDT0 means on OKX's network list
Optimism is a Layer 2 network for Ethereum. USDT0 is something different: according to OKX's USDT0 FAQ (updated Aug 26, 2026), it is powered by LayerZero's Omnichain Fungible Token standard so it can move between chains, and it appears as native USDT in the exchange interface. The same page lists the chains that support USDT0 through OKX: X Layer, Arbitrum One, Optimism, Polygon, Unichain, Berachain, Plasma and Monad.
Coming from Binance, if the withdrawal page offers networks such as Optimism, Arbitrum or Polygon, look at how the matching entry is written on OKX's deposit page before choosing one. A withdrawal needs the receiving platform to support the same network, and sending over one it doesn't support may mean lost funds. If the two labels don't line up and you'd rather not spend time checking, go back to TRC20 or ERC20.
Withdrawing USDT from Binance to OKX, step by step
- Get the address from OKX. In the app, open the on-chain deposit option from the home screen, choose USDT, pick a network, then copy the deposit address the page gives you for that network.
- Enter it on Binance. Open Binance's withdrawal page, choose USDT, and paste in the address you just copied.
- Pick the same network. If you chose Ethereum (ERC20) on OKX, choose Ethereum (ERC20) on Binance as well. Don't choose BNB Smart Chain (BEP20).
- Read the fee before you submit. The withdrawal page shows what this transfer will cost. Check the address, the network and the fee, then confirm.
- Keep the record. After submitting, find the receiving address and the transaction ID (TxID) in Binance's withdrawal history. Both are needed later to trace the deposit or to contact support.
For a first transfer between these two accounts, particularly a large one, you can split it in two: withdraw a small amount, wait until it shows as credited on OKX, then send the rest. That costs one extra withdrawal fee, but a problem with the address or the network shows up on the small transfer.
Already sent USDT to OKX over BSC? Where to get an answer
The Important note in the screenshot at the top of this page says what OKX currently supports on BSC. It doesn't say how a USDT deposit that has already been sent over BSC is shown in your OKX account, or whether anything can be done with it.
Two places at OKX can answer that for your deposit: the Help Center's guidance on withdrawing a balance OKX marks as non-tradable, and OKX's online support. Take what they tell you as the answer. If they say the balance can be withdrawn, the usual condition for any withdrawal applies: the receiving side has to support USDT deposits on the network used.
Right network, wrong address: what to do next
OKX has a help article for deposits sent to a wrong address. It starts on the sending platform: open the withdrawal history, find the receiving address and the TxID, then compare that address with the one on your OKX deposit page.
- The two addresses match: this doesn't count as a wrong-address deposit. If the funds haven't arrived, see OKX's help article on deposits that haven't been credited, or contact OKX support to have the address and the transaction checked.
- The two addresses differ: the address belongs to another platform or to an individual, so contact them. OKX adds that confirmed blockchain transactions generally cannot be reversed and that recovering the funds is not guaranteed.

FAQ
Do I need to verify my identity before sending USDT from Binance to OKX?
The OKX account receiving the coins has to complete identity verification first. OKX's help page on deposit and withdrawal networks notes that identity verification is required to make a deposit, so finish it before you go to copy a deposit address. For the checks Binance applies to a withdrawal, follow the prompts on Binance's withdrawal page.
How does Binance charge for a USDT withdrawal, and where can I see the fee?
Binance charges a flat fee on each crypto withdrawal to cover the blockchain cost of moving the assets out of your Binance account, and the amount depends on the network you choose. When a network is congested, the fee may be adjusted without separate notice from Binance. Once you have selected USDT and a network, the withdrawal page shows the live rate, and Binance states that the figure on the withdrawal page is the one that applies.
