App / Live
Your btk688 account balance moves through Nagad, Rocket and Upay — the wallets already on your phone. Every deposit counter, withdrawal form and transaction record is inside your signed-in account area, where the fields and limits shown are the ones that apply to you.
To add funds, open the deposit counter inside your signed-in account. We support Nagad, Rocket and Upay as the primary wallet routes for Bangladesh. Select the wallet that matches the number registered on your account, enter the amount shown within the field limits, and confirm the transfer from your wallet app. Once the transaction clears on the wallet side, the balance appears in your btk688 account. Follow the exact fields and minimum amounts displayed at the time of deposit — those figures are live and may differ from any cached page you have open. If the counter shows a reference code, keep it until your balance updates.
Log in and navigate to the banking section of your account. Select the deposit option to open the counter.
Pick Nagad, Rocket or Upay — whichever matches the mobile number linked to your btk688 account.
Type the amount within the limits shown on screen, then approve the transfer inside your wallet app.
Once the wallet transaction completes, your btk688 account balance updates. Keep the wallet reference until it does.
Withdrawals go back to the wallet you used to deposit. Open the withdrawal form in your account banking area and select the payout method — Nagad, Rocket or Upay. The form will show the minimum and maximum amounts available for your account at that moment; enter a figure within those limits. You may be asked to confirm your wallet number before the request is submitted. Once submitted, the request enters a review queue and the status updates in your account history. We do not publish fixed processing windows because timing depends on wallet network conditions and any account checks that apply to your profile. Check the status label in your transaction history rather than contacting support immediately after submitting.
Go to the banking section while signed in and select the withdrawal option to see the form and current limits.
Choose Nagad, Rocket or Upay. The wallet number must match the one on your account to proceed.
Type a withdrawal amount within the range shown. Amounts outside the displayed limits will not be accepted.
Confirm the request and monitor the status label in your account transaction history for updates.
Your account area may prompt you to complete identity or wallet verification at certain points — for example, before a first withdrawal or after account activity that triggers a review. We do not publish a fixed document list here because the fields shown in your account are the authoritative ones; follow only what your account screen asks for. Some accounts complete this step quickly; others may require additional information depending on what the system flags. If a verification prompt appears, work through each field in the order shown and submit only what is requested. Avoid submitting documents more than once for the same request, as duplicate uploads can slow the review. If the prompt does not clear after submission, use the support route in your account to follow up with a reference to the request.
Verification fields appear inside your signed-in account. Complete only the steps shown there — do not send documents through other channels.
Upload or enter the requested details once. Duplicate submissions for the same check can delay the review rather than speed it up.
After submitting, the verification status updates in your account area. Check there before contacting support.
If a prompt stays open after submission, contact support through the published route in your account and include the request reference.
We accept the mobile wallet rails that Bangladesh account holders already use. Each method connects directly to your registered mobile number on the account.
Deposit and withdraw via your Nagad wallet. The mobile number must match your btk688 account registration.
Rocket transfers are accepted for both deposits and withdrawals from your account banking area.
Upay is available as a deposit and withdrawal route. Follow the fields shown in your account counter.
Bank transfer may be available depending on your account status. Check the deposit counter for current options.
Every deposit and withdrawal you make through btk688 generates a record on both sides — your wallet app and your account history. Keeping these in sync helps you resolve any mismatch quickly without waiting on support.
Your wallet app issues a transaction reference when a transfer completes. Note this reference and compare it against the entry in your btk688 account history. A matching reference confirms the two records are the same transaction.
Your btk688 account history shows a status for each transaction — pending, completed or flagged. If your wallet shows a completed transfer but the account still shows pending, wait for the status to update before raising a query.
The transaction history inside your signed-in account lists every deposit and withdrawal with the date, amount and method. Filter by date range if you are looking for a specific entry from an earlier session.
Keep your wallet transaction screenshot and the btk688 reference together until the account balance reflects the transfer. If you need to contact support, both references speed up the check considerably.
Account security on btk688 starts with the steps you take on your own device and the checks we run on our side. The safeguards below cover the main areas where account issues typically arise.
Always access btk688 through btk688. Bookmark the address directly rather than following links in messages. A mismatched domain is the clearest sign of a phishing attempt targeting your account credentials.
We only process withdrawals to a wallet registered under your account name. Requests to a different number are declined. Keep your registered wallet number current in your account settings to avoid delays.
Account verification checks that the person withdrawing is the same person who registered. Complete any prompts shown in your account area promptly — an unverified account may have withdrawal access restricted until the check clears.
The published support route is inside your signed-in account. Use that channel for any transaction query and include your account reference. Avoid sharing account credentials with anyone claiming to offer support outside that route.
These are the questions we see most often from account holders about deposits, withdrawals and account checks on btk688.
Nagad, Rocket and Upay are the accepted wallet routes for Bangladesh. The deposit counter in your signed-in account shows which options are active for your account at the time you open it.
Wallet transfers take a moment to confirm on the network side. If your wallet shows the transaction as complete but your btk688 balance has not updated, wait a short time and refresh your account. Keep the wallet reference in case you need to follow up.
Open the withdrawal form in your account banking area, select Nagad or Rocket, enter an amount within the limits shown, and confirm. The wallet number must match the one registered on your btk688 account for the request to go through.
Check the status label in your account transaction history first. If it remains pending beyond what seems reasonable, contact support through the route inside your signed-in account and include the transaction reference from both your wallet and your account history.
The minimum and maximum amounts are shown live inside the deposit and withdrawal forms in your account. These figures apply to your account specifically and may differ from general figures published elsewhere, so always check the form directly.
A verification prompt means our system needs to confirm your identity before releasing funds. Follow the fields shown in your account area, submit once, and monitor the status. Use the in-account support route if the prompt does not clear after submission.
