(105)EBA should establish a college of supervisors for each issuer of significant asset-referenced tokens and of significant e-money tokens. Since issuers of significant asset-referenced tokens and of significant e-money tokens are usually at the centre of a network of entities that ensure the issuance, transfer and distribution of such crypto-assets, the members of the college of supervisors for each issuer should therefore include, amongst others, the competent authorities of the most relevant trading platforms for crypto-assets, in cases where the significant asset-referenced tokens or the significant e-money tokens are admitted to trading, and the competent authorities of the most relevant entities and crypto-asset service providers ensuring the custody and administration of the significant asset-referenced tokens and of significant e-money tokens on behalf of holders. The college of supervisors for issuers of significant asset-referenced tokens and of significant e-money tokens should facilitate the cooperation and exchange of information among its members and should issue non-binding opinions on, amongst others, changes to the authorisation of, or supervisory measures concerning, such issuers.
