Transferring USDT from Walt to OKX is not complicated. The core step is simple: in Walt, choose "Withdraw to external wallet/exchange," paste your OKX USDT deposit address, and make sure both sides use the exact same network. However, Walt's USDT supports multiple chains (TON, TRC-20, ERC-20, Solana), and OKX has its own rules for USDT deposit networks. Choosing the wrong chain is the most common reason these transfers fail.

First, Check Which Network Your USDT Is On in Walt
Walt (formerly Wallet in Telegram) supports USDT on TON, TRC-20 (Tron), ERC-20 (Ethereum), and Solana networks. The USDT you received or bought in Walt may be on a specific chain. Open Walt, tap your USDT balance, and check the network label for this asset. If the interface does not show it directly, when you select USDT on the withdrawal page, the system will ask you to choose a network. That option is the information you need to remember.
Get Your Address from OKX — Networks Must Match
Open the OKX App, go to Assets → Deposit, and select USDT as the coin. OKX will list the currently supported USDT deposit networks. You need to find the one that exactly matches the network you are withdrawing from in Walt, then copy the corresponding deposit address.
There is a known limitation to note: OKX's official documentation clearly states that the platform does not support BSC chain USDT deposits. If your Walt USDT is on BSC, this route will not work. You would need to first convert it in Walt or elsewhere to a chain OKX supports (like TRC-20 or ERC-20) before proceeding. Additionally, OKX has minimum deposit requirements for USDT. Third-party tutorials often cite reference values of 10 USDT minimum for TRC-20 and 20 USDT minimum for ERC-20, but always refer to the number shown on your OKX deposit page in real time. Transfers below the threshold may not be credited.
Regarding network choice, if your Walt USDT is on TRC-20, this is usually the lower-cost and faster route. If it is on TON, you need to confirm whether OKX currently supports USDT deposits on the TON network. Walt's official help documentation confirms that TRC-20 withdrawals are usually completed instantly after transaction review, but the actual crediting time to OKX also depends on OKX confirmation requirements and on-chain status.
Execute the Withdrawal in Walt
Go back to Walt and start the withdrawal process. The path described in Walt's help documentation is: tap Withdraw, select External wallet or exchange, then choose the asset (USDT) and fill in the recipient address.
Paste the deposit address you copied from OKX. Walt may ask you to confirm the network. Here you must select the same chain as shown on the OKX deposit page. If the OKX USDT deposit requires a Tag/Memo (USDT usually does not, but some networks or coins may), the OKX page will display it separately. If Walt's withdrawal page has a corresponding memo field, fill it in; if not, leave it blank. Walt charges a fee for withdrawals to external addresses and has amount limits. Before confirming, the page will show the actual fee deducted and the amount to be received. Review carefully before submitting.
What to Check After Submitting
After submitting the withdrawal in Walt, first check the transaction status inside Walt. Walt's documentation states that withdrawals usually need to go through a review process, generally taking up to 12 hours at most. If the status remains "Processing" for a long time, you can contact Walt support. Once the status changes to "Success," a transaction hash (TxID) will appear. You can use it to check on-chain confirmation status on the corresponding block explorer.
At the same time, check the status of this USDT in OKX's Deposit Records. OKX needs to wait for the required number of on-chain confirmations before crediting your account. If Walt shows "Success" and there are already on-chain confirmations, but OKX has not credited your funds after a long time, use the TxID to check on OKX's deposit record page. If necessary, submit the TxID for inquiry through OKX's customer service channels. It is important to distinguish: Walt showing "Success" only means the funds have been sent out. OKX showing "Credited" means you can actually use the money.
A Premise You Need to Confirm
Walt's help documentation does not explicitly list the complete set of available networks for "withdrawal to external address." It only mentions differences in arrival speed for networks like TON, TRC-20, and FLR, as well as USDT support for TON, TRC-20, ETH, and Solana networks. Therefore, the network options you actually see on Walt's withdrawal page are the ones you can choose from. If a network supported by OKX is not there, do not force the operation. First confirm which chain your USDT is on in Walt, then cross-check with the supported list on OKX's deposit page. The chain that matches on both sides is the only correct choice.
