(3)To ensure that competent authorities can effectively monitor the issuance and offer to the public of crypto-assets other than asset-referenced tokens and e-money tokens, competent authorities should exchange information relating not only to the crypto-assets themselves, including their technical characteristics and categorisation, but also to the offer of the crypto-assets, the issuers and offerors of the crypto-assets and the persons seeking admission to trading of crypto-assets. In particular, competent authorities should exchange general information and documents allowing the identification of the relevant persons and the understanding of the crypto-asset issuance and offering, including notified crypto-asset white papers, as well as information related to identified breaches, penalties and measures, enforcement actions and relevant compliance and conduct history.
