Who holds your money,
and under whose licence.
This page answers without hedging: which entities route your transfer, how it settles, and what actually backs the balance you see. Every number below can be checked at its source.
How SDB Wallet is built
Your euro receiving details — including an IBAN assigned to you — run through Bridge over the network of a licensed European credit institution supervised by its national financial regulator. The IBAN is assigned to receive and reconcile your transfers; it does not mean you hold a retail bank deposit directly with the bank that carries the IBAN.
After a transfer arrives, Bridge settles its value into the stablecoin backing described below. SDB Wallet builds the product and manages your relationship and balance; every entity in the chain and its role are named below.
Legal identity: SDB wallet LLC · Dubai, United Arab Emirates · commercial licence 2652156.01. An independent banking licence is a goal we are working towards.
The chain, link by link
From the moment a transfer is sent to where the money rests.
- The company running the app
SDB Wallet
We build the product, verify your identity, open your account, and run your balance, transfers and remittances. Choosing the licensed institutions that hold the money — and supervising that relationship — is ours.
- Banking-infrastructure partner
Bridge
Our direct financial partner for banking infrastructure, account details, payment rails and settlement. Bridge is entirely separate from Axis X, the software company.
Official Bridge website ↗ - The banks that carry your accounts
Licensed banking institutions
Accounts issued through Bridge run over the networks of licensed banks. The name of the bank carrying your account is printed on your account details inside the app.
And pounds: your GBP account runs on an account number and sort code over Faster Payments, through the same partner. The name of the institution holding it is not something we have on record — and we will not print a name we cannot stand behind.
Where SDB Wallet holds its own accounts
Our operating accounts are held at global banking institutions: a licensed EU banking institution for euros, Citibank N.A. in New York for dollars, and Citibank in London for pounds.
We do not publish the account numbers. Any payment request reaching you in SDB Wallet's name should be verified inside the app or through support — never from a public page or a message.
Everyone else we work with
KYCAID
Identity verification — document reading and face matching.
ChangeNOW
Crypto swaps our banking partner does not carry.
Axis X Group
Software development and app-store publishing only. It is not a financial partner, does not hold customer funds, and does not issue accounts or IBANs.
Your balance, and what happens to it
The balance shown on screen stays denominated in its fiat currency. After a transfer arrives, the euro balance is backed by EURC and the US-dollar balance by USDC. Incoming pounds are converted to US dollars and backed by USDC; the applied exchange rate is shown on the transaction. That backing is a stablecoin, not a retail bank deposit held directly in your name.
When withdrawing, you request a payout to your bank account in the currency shown by the app before confirmation. An automated check compares the backing with amounts owed to customers every night, and any difference triggers a review alert.
How to check for yourself
Bridge
Our direct financial partner — its official website and public documentation.
Bridge website ↗Our Dubai licence — plainly
It is 2652156.01, and it is stated in our terms. But free-zone companies are not all listed on the federal register, and Meydan has no public licence-number lookup. So there is no external source we can point you to today — and we would rather say that than leave it out.
Our terms
The same statements appear in the agreement you sign, not only here.
