The Markets in Crypto-Assets Regulation (MiCA) delivers a new EU-wide regulatory framework for issuing, intermediating and dealing in crypto-assets. Under MiCA, Crypto-asset service providers (CASPs) must be authorised, comply with conduct, disclosure, governance and organisational requirements and have prudential safeguards in place. In this briefing we take a closer look at some of the wider EU regulatory requirements that will attach to some CASPs for the first time, and to existing service providers more broadly, as EU-regulated entities.
