What the end of MiCA's transitional period means for crypto businesses

On July 1, 2026, the transitional window under the Markets in Crypto-Assets Regulation (MiCA) closes for good. Under Article 143(3) , cryptoasset service providers (CASPs) that were operating legally under national regimes before MiCA applied could keep trading while they pursued full authorization. For any organization still relying on that cover, the legal basis to serve EU clients now closes with it.
