The exact cause of the incident has not been clearly explained yet. The Flow Foundation issued an emergency statement on X platform nearly three hours after the price crash, stating that they are investigating an incident that may affect network security.

The Flow Foundation is currently investigating a potential security incident affecting the Flow network.
