Read These Terms Before You Start

These terms set out what you agree to when you open and use an x400 account — from how deposits clear through bKash, Nagad or Rocket to how disputes are handled.

HOW WE OPERATE

How x400 Applies These Terms Day to Day

These terms are not just a document we publish and forget. They shape how every account action — deposit, withdrawal, dispute — actually runs. Here is what that looks like in practice when you use bKash, Nagad or Rocket with your account.

Wallet Verification

Before we release a withdrawal to your bKash, Nagad or Rocket number, we check that the wallet name matches the account name you registered with. This step exists to protect your funds.

Account Security

Your account is protected by a one-time password sent to your registered mobile number at login. We never ask for your PIN over chat or email — if someone does, contact us immediately.

Dispute Handling

Raise a dispute through live chat or email within the window stated in these terms. We log every dispute with a reference number and aim to respond with a decision before the window closes.

Terms Updates

When we update these terms, we publish the new version on this page and notify you via your registered contact. The change date appears at the top of the document so you always know what version is live.

Common Questions About x400 Account Terms

These are the questions we hear most often from people reading these terms for the first time. If yours is not here, contact support and quote the relevant section.

Eligibility depends on your local law and the regions x400 currently supports. Check your local regulations before opening an account — using the platform is your responsibility under applicable law.

On account closure, any wallet details saved to your profile are removed from our system within the period stated in our data retention policy. Pending withdrawals are processed first before closure is finalised.

No. We notify you through your registered contact details before a material change takes effect. Continued account use after that date counts as acceptance of the updated version.

Screenshot the confirmation from your Rocket or Nagad app, then contact live chat with your account reference and the transaction time. We trace the payment and update your balance once it is confirmed.

The dispute window is set out in the relevant section of the full terms document on this page. Raise your case within that window — disputes submitted after it may not be eligible for review.

Providing false account details, using someone else's bKash or Nagad wallet, or attempting to manipulate account balances are all breaches. Consequences range from a transaction hold to permanent account closure, depending on severity.
