The Impact of Blockchain Security Breaches on Crypto Token Valuation

Abstract

Against the backdrop of rapid advancements in blockchain technology, blockchain derivative projects have been exposed to security breaches. These projects often raise funds by issuing tradable crypto tokens representing project stakes. Using the event study method, this research investigates the impact of blockchain security breaches on the token value of these projects. The study provides evidence of a significantly negative impact on token price on the breach day and over a three-day event window centered on the breach day. Projects primarily offering financial services within the blockchain ecosystem suffer more negative abnormal returns compared to non-financial projects. Additionally, we find that official X.com announcements about the breach from the project may be more damaging than remaining silent. This research is the first to study the breach impact on token value, contributing to the literature by assisting risk assessment for investors and emphasizing the prioritization of security in crypto token investing.
