Paradex Addresses Database Upgrade Incident with Comprehensive Measures

Paradex has released an investigation report on the incident that occurred on January 19. According to Foresight News, during a database upgrade and maintenance, a race condition during service restart led to data corruption, which was published to the Paradex Chain. This resulted in the reset of some market funding rate indexes and abnormal liquidations. The company decided to roll back the chain state to the snapshot before maintenance and canceled all orders except for take-profit and stop-loss orders. Within 24 hours, Paradex audited the affected accounts and refunded a total of $650,000 to 200 accounts from the Liquidator Vault. This incident marked the first rollback operation on the Paradex Chain. Enhanced service restart procedures, additional data validation safeguards, and price range protection measures during post-only periods have been implemented. Discrepancies in data related to portfolios and Vault pages are expected to be resolved by January 26.
