Article 4 Publication en temps réel des transactions

Summary What does Article 4 of the RTS on trading platform transparency data say?

This article builds directly on Article 3, which establishes what transaction details must be disclosed, by adding a strict timing requirement for when that disclosure must occur.

It sets a clear deadline for crypto-asset service providers operating trading platforms to publish post-trade transaction data, anchoring the obligation to the moment of execution.

Important points:

Publish full transaction details as close to real-time as is technically possible after each trade is executed.
The absolute maximum time allowed between execution and public disclosure is thirty seconds — there are no exceptions to this deadline.
This obligation applies to crypto-asset service providers operating a trading platform, specifically for transactions executed on their own platforms.

Springlex's summary of the article, a reading aid, not a substitute for the legal text.

Pour les transactions exécutées sur leur plate-forme de négociation de crypto-actifs, les prestataires de services sur crypto-actifs qui exploitent une plate-forme de négociation de crypto-actifs rendent public le détail de chaque transaction comme prévu dans les tableaux 1, 2 et 3 de l’annexe II dans un délai aussi proche du temps réel que le permettent les moyens techniques, et en tout état de cause dans les trente secondes qui suivent l’exécution de la transaction.
