The Markets in Crypto-Assets Regulation is the first European-level legislation introducing a harmonised and comprehensive framework for crypto-assets, covering issues from the offering to the public of crypto-assets to preventing market abuse in crypto-asset markets. The legislation provides a set of prescriptive rules that will shape the functioning of the European markets in crypto-assets, including transparency rules, authorisation requirements, customer protection rules and an anti-market abuse framework. An online consultation portal is now open to allow all stakeholders to submit their views on whether and how Ireland should exercise national discretions contained within MiCAR.
