The evolution of laws relating to financial settlement has long reflected an ongoing accommodation between legal and operational certainty. Tokenisation seeks to reconcile these dimensions, promising legally final and enforceable transfer alongside instantaneous, automated execution.

This article examines the legal character of that structure, focusing on stapling, extinguishment and negotiability.
