How to deposit euros on OKX by SEPA bank transfer
Euro deposits to OKX from an EEA country go by SEPA bank transfer, sent from a bank account in your own name. The steps are the same on web and app; what varies is whether your bank sends Standard or Instant.
Which OKX entity takes euro deposits
In Europe, OKX operates through OKX Europe Limited, a Maltese company. ESMA's interim MiCA register lists it as a crypto-asset service provider authorised by the Malta Financial Services Authority (MFSA) on 27 January 2025, with Malta as its home member state and 29 other EEA countries, Romania among them, where it provides services. The same company is also licensed by the MFSA as a financial institution for payment services. EUR bank transfers are currently offered only to residents of EEA countries (OKX's SEPA help article).
Depositing EUR with SEPA
SEPA (Single Euro Payments Area) is the standard euro bank-transfer network across the EEA. The flow is the same shape whether you start on the web or the app:
Open the deposit screen
On web: Assets → Deposit → Cash, then pick EUR. On the app: Transfer (or Portfolio → EUR under Cash), then Deposit.
Choose bank transfer (SEPA)
OKX shows you an IBAN and a reference to use — this is the account you're sending to, generated for your deposit specifically.
Send the transfer from your own bank
Use the exact IBAN shown, don't retype or "fix" it, and send from an account that's actually in your name — OKX's own guidance is explicit that the sending account holder name has to match your verified identity.
Wait for confirmation
Once the transfer clears, EUR shows up in your OKX balance automatically — no manual "I've paid" step like P2P requires.
SEPA Standard vs. SEPA Instant
OKX's help pages describe two speeds of the same rail, and which one you get can depend on your bank:
- SEPA Standard — typically clears in one to two business days, the same timing as an ordinary bank-to-bank euro transfer.
- SEPA Instant — settles in seconds, available around the clock including weekends, at whatever per-transaction cap OKX shows on the deposit screen (EU instant-payment limits have changed since SEPA Instant launched, so treat that on-screen figure as the current one, not a number repeated from memory).
Not every bank supports SEPA Instant on the sending side, so which one you actually get can be a function of your own bank rather than a setting you pick on OKX. If a transfer is taking longer than you expected, that's usually the standard rail rather than something wrong with the deposit itself.
Cards and other routes in
SEPA isn't the only way in. OKX Europe's site menu lists Visa and Mastercard next to SEPA under Buy and Sell. Which methods an account is offered depends on its region and on the identity documents verified at onboarding. The fee, the limit and the processing time for a method appear once you select it.
Depositing from Romania specifically
A Romanian resident is an EEA resident, so the SEPA route above applies. The practical point is currency: OKX's SEPA deposit takes euros, so a balance held in lei (RON) has to be converted before the transfer is sent.
Two ways to handle the conversion:
- Convert inside a multi-currency account first, then send EUR over SEPA. Some bank accounts let you hold a EUR balance alongside RON and convert between them before initiating the transfer, so the SEPA payment itself leaves as euros with no conversion happening mid-transfer. Send it from a bank account in your own name: OKX's SEPA help article says deposits from e-wallets such as PayPal, Wise or Airwallex are not supported and will be returned.
- Use a traditional Romanian bank's own currency-exchange step. Banks such as BCR, BT, or ING can convert RON to EUR as part of sending an international transfer — the rate and any conversion fee are set by that bank, not by OKX, so it's worth checking your bank's own FX terms before assuming SEPA's "no OKX fee" line covers the currency conversion too.
Either way, the SEPA transfer that actually reaches OKX needs to arrive in euros, from an account whose registered name matches your verified OKX identity.
The MiCA transitional period
MiCA let firms already operating under national law before 30 December 2024 carry on for a transitional period. ESMA describes it as running until 1 July 2026, or until the firm was granted or refused a MiCA authorisation. Applying it was optional for each member state. OKX Europe Limited was authorised on 27 January 2025, before that period ended. To check any other exchange, look up its legal entity in the register.
