Your i688 account wallet sits at the centre of every session — deposits come in through Nagad, Upay and bKash, and withdrawals go back to the same wallet you used. Availability depends on your local law and eligible region; where access applies, every action is handled directly inside your account area without switching apps.
Funding your account starts at the cashier section inside your dashboard. We support Nagad, Upay and bKash as local wallet deposit channels — choose the one already on your phone and follow the steps shown in the cashier. The amount field and wallet details are both on-screen; you do not need to leave the site or open a separate browser tab.
Log into your i688 account and navigate to the cashier section. The deposit tab is visible by default on both mobile and desktop.
Select Nagad, Upay or bKash from the payment list. The cashier shows only the channels available for your account region.
Type the deposit amount into the field shown, then follow the wallet confirmation screen on your device. Do not close the page mid-step.
After wallet approval, return to your account dashboard. The credited amount appears in your balance row. Save the wallet reference for your records.
Withdrawals from your i688 balance follow a straightforward path: open the withdrawal tab in the cashier, pick the same wallet you deposited with, and enter the amount you want to move out. We match withdrawals to the wallet that funded the account — this is a standard ownership check, not an extra barrier. Before you submit, verify the wallet number on screen matches your registered account details; a mismatch will cause the request to pause for manual review.
From your signed-in dashboard, go to the cashier and select the withdrawal option. The form loads with your account's registered wallet details pre-filled.
Choose Nagad, Upay or bKash. The cashier limits your choices to the wallet linked at registration, keeping the ownership trail clean.
Fill in the amount field. Complete any verification step shown on screen — this could be a wallet number confirmation or a one-time check prompted by your account status.
After submission, the status updates in your transaction history. Note the reference number shown so you can quote it if you contact account support.
Account verification on i688 is driven by the fields and prompts visible inside your own account area — not by a fixed document list we publish here, because the fields shown depend on your account status and the region rules applied at registration. When a check is required, a prompt appears in your dashboard or at the cashier step.
Verification requests appear as prompts in your dashboard or cashier. The exact fields required depend on your account's current status and the checks active for your region.
Use only the upload or confirmation field shown inside your i688 account area. Do not send personal information via chat, email or any external link claiming to be us.
If a field asks for your registered wallet number — Nagad, Upay or bKash — enter it exactly as it appears in your wallet app. A mismatch will pause the verification step.
Once a verification step is complete, it is recorded in your account history. Keep this accessible if you need to reference the completion status later.
The payment channels available in your i688 cashier are drawn from Bangladesh's most-used local wallets and transfer routes. Each method shown in the cashier has been configured for your account region — if a channel does not appear, it is not available for your current account. Nagad and Upay are the two verified primary wallet channels on our platform. bKash is also listed as a supported deposit route.
Nagad is a verified deposit and withdrawal channel on i688. Use your registered Nagad mobile number when entering wallet details in the cashier.
Upay is a verified transfer route for i688 account funding and withdrawals. Select Upay in the cashier and match the wallet number to your Upay account exactly.
bKash is available as a deposit route. Enter your registered bKash number in the cashier field; the account name must match your i688 registration details.
Where bank transfer is enabled for your account region, the cashier displays the relevant bank details. Follow only the bank information shown on that screen.
Every deposit and withdrawal you complete generates two records: one on your wallet app and one in your i688 account transaction history. Keeping both in sync is the fastest way to resolve any question about a missing credit or a withdrawal status.
Every Nagad, Upay or bKash transaction generates a unique reference in your wallet app. Screenshot it or note it down at the time — this is the first detail our support team will ask for if a credit is delayed.
Your i688 transaction history uses status labels such as Pending, Confirmed and Processing. A Pending label means the transaction is not yet settled; wait before contacting support or re-submitting.
Open the history tab in your signed-in account to see a full list of deposits and withdrawals. Each row shows the method, amount, date and current status — filter by date if you need to locate a specific transaction.
Hold onto the wallet receipt and the i688 history row for any transaction you want to query. Having both on hand — wallet reference and account row — shortens the support resolution process significantly.
Account security on i688 starts with the steps you take on your own device and ends with the published support route if something goes wrong. We do not contact you asking for wallet PINs or passwords — any message claiming to be from i688 and asking for those details should be reported immediately. Your registered wallet number ties your cashier access to a single, verified mobile account, which limits the routes through which a payout can be sent.
Always confirm you are on the correct i688 address before entering your credentials. Bookmark the domain directly rather than following links sent via messaging apps or SMS to avoid phishing pages.
The cashier links your account to the specific Nagad, Upay or bKash number registered at sign-up. This means payouts can only route back to your own verified wallet, not to an unregistered number.
Certain account actions — large withdrawals or a change to registered details — may prompt an identity confirmation shown on screen. Follow only the fields displayed in your account area; do not share information outside it.
If a transaction does not match your records or your account is behaving unexpectedly, contact support through the channel listed inside your signed-in dashboard. Keep your wallet reference and transaction row ready before you reach out.
These are the questions we see most often from account holders about deposits, withdrawals and balance management. If your question is not covered here, the support route in your account dashboard is the right next step.
Nagad and Upay are the verified primary wallet channels. bKash is also available as a deposit route. The cashier shows only the channels active for your account region, so go there to confirm what applies to you.
Withdrawals route back to the wallet registered on your account — the same one used at deposit. This wallet-matching step is a standard ownership check. To change your registered wallet, contact support through your account dashboard.
Check the status label in your account transaction history first. If it shows Pending, the wallet network is still settling it. Note your Nagad reference number and contact account support if the status does not update after a reasonable wait.
Minimum amounts are displayed on the deposit form in your cashier. We do not publish a fixed figure here because it can vary by wallet channel and account region — check the cashier screen for the figure that applies to your account.
Verification prompts appear inside your account area when they are required. Follow only the fields shown on screen. Wallet number confirmation is the most common step — enter it exactly as registered in your Nagad, Upay or bKash app.
Open the transaction history tab in your signed-in account. Each row shows the payment method, amount, date and status. Quote the i688 reference and your wallet receipt reference when you contact support — having both speeds up any query.
