(5)Distributed ledger technology has given rise to innovative structures in crypto-asset trading platforms. Crypto-asset trading platforms are often differentiated as either off-chain Centralised Exchanges (CEXs) or on-chain Decentralised Exchanges (DEXs), such as those operated under an automated market maker model. CEXs are characterised by centralised control over trading operations and custodial practices. CEXs typically use mechanisms which are common in traditional finance, including central limit order books. DEXs, by contrast, operate without a central operator and facilitate trading directly on distributed ledgers through smart contracts, while allowing users to trade using their non-custodial wallets. In addition, the evolving landscape that includes hybrid models that combine features of both CEXs and DEXs necessitates a regulatory approach that is both precise and adaptable. In view of these developments, it is appropriate to clarify the transparency data requirements applicable to those trading systems that facilitate trading directly on distributed ledgers through smart contracts, in as much as they are not operated in a fully decentralised manner without intermediary and hence subject to Regulation (EU) 2023/1114.
