Incident Overview
The network was paused to contain further impact. Engineers prepared a fix for validation on a shadow fork and are evaluating a targeted recovery that would keep finalized history and legitimate user state while reversing only incident-related invalid changes. Users were told not to submit or rebroadcast transactions and not to deposit or withdraw EGLD or ESDT via exchanges or bridges.
