(6)In the course of the substantive assessment of the crypto-asset white paper by the competent authority, which aims to ensure compliance of the crypto-asset white paper with the requirements of Article 19 of Regulation (EU) 2023/1114, the competent authority should be able to request improvements to the crypto-asset white paper submitted by the credit institution to the competent authority. That is necessary to ensure that the crypto-asset white paper meets the requirements set out in that Regulation in the most efficient manner, i.e. without having to re-start anew the whole procedure for the crypto-asset white paper approval, which could disproportionately delay the launch of the asset-referenced token. It also gives a possiblity to the competent authority to request the credit institution to address any comments or suggestions of the ECB or the relevant central bank in its positive opinion. To allow for a smooth and harmonised approach to the approval procedure, the timeline for the final decision of the competent authority on the crypto-asset white paper approval should be specified.
