With the arrival of the MiCA regulatory framework (Markets in Crypto-Assets Regulation), ESMA, the financial markets authority, is calling for swift action against stablecoins that do not comply with the new standards. This regulatory shift, aimed at protecting investors and ensuring transparency, heralds a major overhaul of the European crypto ecosystem and poses significant challenges for both issuers and trading platforms.
