Is this crypto firm authorised in the EU? One call checks the official ESMA interim MiCA register of authorised crypto-asset service providers (CASPs) AND the EU non-compliant entities warning list. Search by firm name, platform website/domain, or LEI. Returns authorisation details (member state, competent authority, authorised services, LEI) and any warning-list entries, each with an official source reference. Firms only. Counterparty/scam check before sending funds to a platform.
