The new MiCA Regulation (Markets in Crypto-Assets) will introduce a common framework in 2025 for all companies operating with crypto-assets in the European Union. In Spain, the CNMV will be the authority responsible for authorizing crypto-asset service providers (CASPs).
In this guide prepared by IN DIEM Abogados, with the technical collaboration of Cryptoveritas 360, we explain how to obtain the CASP license step by step, what requirements the CNMV demands, and why Spain is consolidating its position as one of Europe's leading regulatory hubs for crypto, fintech, and tokenization projects.
What is a CASP and why should you register?
If you operate with crypto-assets in Spain, understanding what CASP is is not optional: it is a legal obligation.

At IN DIEM, together with Cryptoveritas 360, we have been guiding companies through this process for over three years. If you have doubts about whether your activity requires CASP registration, you need to read this before continuing to operate.
