OKX Europe lets customers convert USDT into MiCA-compliant USDC across 30 EU and EEA countries

OKX Europe has added a one-way conversion flow that lets users deposit USDT and turn it into USDC, giving customers a regulated path off a stablecoin that does not have MiCA authorization. For PSPs and crypto platforms in Europe, the point is simple: the compliance problem is no longer theoretical, and exchanges are already building migration rails instead of waiting for a deadline to do the work for them.

1. According to a company announcement shared with Cointelegraph, the feature allows customers to deposit Tether’s USDt (USDT) into their OKX Europe account and convert it into USDC (USDC), which is one of the largest stablecoins available under the European Union’s Markets in Crypto-Assets (MiCA) framework.
2. Tether has not obtained authorization to issue USDT under MiCA. As a result, many European platforms have restricted deposits, delisted trading pairs, or converted customer balances into compliant alternatives after the European Union completed the framework’s rollout on July 1.
3. OKX Europe said the conversion feature is meant for customers whose existing platforms no longer accept USDT or plan to migrate balances automatically. The exchange said users can complete conversions at their own discretion rather than being pushed through a platform-imposed deadline.
4. The market backdrop is still very much USDT-heavy. According to DefiLlama, Tether accounts for about 59% of the nearly $310 billion stablecoin market, with a market capitalization of roughly $184 billion, compared with about $73 billion for Circle’s USDC.
5. OKX Europe said it serves customers across 30 EU and European Economic Area countries under its MiCA license. That makes this more than a product tweak: it is a cross-border operating decision inside the EU’s post-MiCA stablecoin framework.

Tether has defended its refusal to seek MiCA authorization for USDT. CEO Paolo Ardoino has argued that MiCA’s reserve rules create unnecessary risks for stablecoin issuers by requiring part of reserves to be held with European credit institutions. In a May 2025 interview with Cointelegraph, he called the framework “very dangerous when it comes to stablecoins,” and in a July 2025 post on X he said Tether would reconsider seeking authorization only “when MiCA becomes safer for consumers and stablecoin issuers.”

The rest of the market is already adjusting. Revolut recently said it will stop supporting USDT for customers in the European Economic Area and Switzerland, giving users until Aug. 31 to sell or withdraw their holdings before automatically converting any remaining balances into their base currency.
