Abstract

La présente invention concerne un procédé de mise en correspondance d'actifs, un système de mise en correspondance d'actifs, ainsi qu'un dispositif et un support d'informations. En exécutant une transaction de premier ordre en attente, un premier contrat est déclenché de manière à geler plusieurs premiers actifs qui sont actifs, et en exécutant une transaction de réception de premier ordre, le premier contrat est déclenché de façon à achever la conversion des premiers actifs gelés d'un premier utilisateur à plusieurs seconds actifs, dans le premier contrat, d'un second utilisateur, le premier contrat étant configuré à l'aide d'un système de compte, et le système de compte étant utilisé pour enregistrer des informations d'actifs concernant des actifs transférés au contrat par divers utilisateurs, ce qui permet de fournir un mécanisme de mise en correspondance d'actifs permettant aux utilisateurs de faire correspondre les actifs de manière sécurisée et rapide de façon à réaliser un échange d'actifs.
