A deposit on sd678 is a wallet transfer, not a card payment. You send taka from bKash, Nagad, Rocket or Upay, and the same amount appears in your game balance. No card number, no bank queue, no paperwork at a counter.
This guide is written for the phone in your hand. It explains what each wallet is good for, the exact order of taps from opening the cashier to seeing your balance move, and the handful of problems that cause most failed top-ups. Keep it open the first time you fund your account.
Before you start, have these ready
- A wallet with at least ৳250 in it. That is the smallest deposit sd678 accepts, and anything lower bounces back.
- The same mobile number on your wallet and your sd678 account, so support can match the transfer without extra questions.
- A steady connection, or enough phone credit for a USSD session if you deposit with Rocket.
- Your NID, passport or driving licence somewhere nearby. You will need one of them before your first withdrawal, not before your first deposit.
Pick the wallet that fits your phone
All four methods end in the same place and take the same five minutes. The real question is which app already holds your money. Use that one and you will not need to move cash between wallets first.
bKash is what most players reach for, because the agent counter is never far away. Nagad is quick when you are topping up on the move. Rocket runs on USSD menus, so it still works on a basic handset with no data pack. Upay is a tidy in-app cash-in if you already use it for bills and recharges.

Every method shares the same floor: ৳250 per deposit, credited within five minutes. Cash-outs start at ৳1,000 and usually land in twenty minutes, with a daily ceiling of ৳250,000 before your VIP tier raises it.
| Method | Smallest deposit | Credited in | Where it fits |
|---|---|---|---|
| bKash | ৳250 | 5 minutes | Most familiar to players; agents everywhere |
| Nagad | ৳250 | 5 minutes | Fast top-up when you are not near a counter |
| Rocket | ৳250 | 5 minutes | USSD menus that work without mobile data |
| Upay | ৳250 | 5 minutes | One app for bills, recharges and deposits |
Keep one thing straight: the amount you send from the wallet must match the amount you type in the cashier. A ৳500 transfer with ৳250 entered sits unmatched until support steps in and fixes it, which costs you time you did not need to spend.
Cash-in, step by step
Follow this order and you skip most of the errors people run into. After the second try it takes about a minute from login to a ready balance.

1
Log in to your sd678 account
Open sd678 on your phone or in a browser and sign in. New here? Finish registration first, then come back to this page. The cashier only exists inside an account.
-
2
Open the cashier and choose a wallet
Tap Deposit, then pick bKash, Nagad, Rocket or Upay. The screen shows the wallet number that sd678 uses for that method, plus the reference you should keep.
-
3
Type ৳250 or more
Enter the amount in taka. Anything under ৳250 is rejected by the cashier, so if you are testing the flow, send the minimum rather than a smaller round figure.
-
4
Approve the payment in your wallet
Switch to your wallet app or USSD menu, send the exact amount to the number shown, enter your PIN and confirm. Copy the transaction ID from the confirmation SMS.

Wait for the balance to move
Most deposits land inside five minutes. Refresh the cashier once, then open your transaction history before you consider sending anything again.
Depositing from the app
The sd678 app is 28 MB, runs on Android 6.0 and above, and keeps the cashier one tap from the lobby. You still pay through the same four wallets, so nothing about the steps above changes.
Get the AppIf you type a transaction ID by hand, read it back against the SMS one character at a time. A single wrong digit is the most common reason a real payment ends up sitting in review while your balance stays empty.
Why a deposit fails and what to do next
Almost every failed top-up matches one of the rows below. Find the message you are looking at, follow the fix, and only then think about sending money a second time.
| What you see | Why it usually happens | What to do |
|---|---|---|
| Money left the wallet, balance unchanged | The transfer is still queued on the wallet side | Wait five minutes, refresh the cashier, then check transaction history |
| Amount below the minimum | You entered less than ৳250 | Send ৳250 or more in one transfer, not two smaller ones |
| Transaction ID not recognised | A digit was copied wrong by hand | Compare with the SMS and resubmit the same ID |
| Wallet says insufficient balance | Your bKash or Nagad float is short of the amount | Top up the wallet first, then return to the cashier |
| Wallet daily limit reached | You hit your own wallet cap for the day | Switch to another of the four methods for this deposit |
| Account under review | Documents not checked yet before a first cash-out | Send your NID, passport or driving licence; review takes about two hours |
| Bonus not showing in cash | The bonus sits in a separate balance until wagering clears | Play through the 13x requirement, then it becomes withdrawable |
Never send a second transfer because the first one looked slow. If the original payment does reach sd678, you have deposited twice and the extra amount needs a manual refund. Check history, wait out the five minutes, then talk to live chat.
Before you open live chat
- The transaction ID from your wallet SMS, exactly as written.
- The amount you sent and the time you sent it.
- A screenshot of the wallet confirmation, if your phone saved one.
Support runs 24/7 from inside your account, and a message with those three items usually gets a deposit traced in one reply instead of five.
Questions before your first cash-in
- Cash-in basics Minimum amount, speed and which wallets you can use.
- Failed payments What to check before you contact live chat.
- Limits and bonus Wagering, cash-out ceilings and how VIP tiers move them.

Registration asks for a few basic details and a password, and takes a couple of minutes on a phone. Once you are in, the cashier handles the ৳250 top-up and applies the 135% welcome bonus on the same screen.
