CASP Tracker is an online information resource for checking crypto-asset service providers against the European Union’s Markets in Crypto-Assets (MiCA) framework. Its central feature is a searchable list of 367 providers reported as authorised in the official European Securities and Markets Authority (ESMA) register, verified on 9 October 2026. Users can look up a company by name, browse providers by country or regulator, and filter results by the crypto-asset services each provider is permitted to offer.

The register covers services including crypto-asset custody, trading-platform operation, exchanges between crypto and funds or other crypto-assets, order execution and routing, placing, advice, portfolio management, and transfers. Provider listings include details such as the legal entity, home country, competent authority, authorisation date, official website, and authorised services. CASP Tracker also highlights frequently searched companies and offers a dedicated page for locating licensed crypto exchanges. The site presents its data as compiled from the official ESMA register and includes information about its verification and synchronisation dates, helping visitors assess a provider’s reported MiCA status.
