USDT One Way Convert FAQ
USDT can be deposited, but can only be converted to USDC. This is because USDT is not a permissible stablecoin in the EU, as its issuer has not obtained the authorisation required under Markets in Crypto Assets Regulation (MiCA). As a result, USDT trading is no longer available on OKX Europe. If you hold USDT, you can convert it to USDC, a MiCA-compliant stablecoin, on a one-way basis while this service remains available.
What is USDT Convert?
USDT Convert lets eligible users deposit USDT into OKX and convert it, one time, into USDC. Conversion only runs in one direction: USDT into USDC.
Who can use USDT Convert?
Users located in the European Economic Area (EEA), with access to OKX through the web platform or the app.
From which date can USDT be converted to USDC?
17 July, 2026.
Does this new feature reopen USDT trading on OKX in Europe?
No. USDT Convert does not reopen USDT trading, and it doesn't let users hold USDT as an investment on OKX in Europe. Deposits accepted through this feature are for conversion purposes only.

Converting USDT to USDC
How do I convert my USDT to USDC?

What happens if I change my mind after converting?
The conversion cannot be reversed. Confirm the amount before completing the conversion.
Using Converted USDC
What can I do with USDC after converting?
USDC is the settlement asset used across OKX's order books, so USDC received through conversion can be used directly for trading on OKX. It can also be used as a margin for X-Perps and Futures Bots, for Earn APY and to spend it via the OKX Card.
Do I need to deposit USDC separately to trade with it?
No. USDC received through USDT conversion is usable after being converted via the Convert feature.
Eligibility and Access
I hold USDT on another exchange. Can I still use this feature?
Yes. Deposit that USDT into your OKX Europe account first, then convert it into USDC using USDT Convert.
I'm not located in the European Economic Area (EEA). Can I use this function?
No. This USDT Convert function is currently only available to users in the EEA on OKX's web platform and app.
