Paradex has announced plans to refund $650,000 to 200 users following a maintenance glitch that led to liquidation events. According to PANews, the issue arose during a scheduled 30-minute database upgrade on January 19, when unexpected problems occurred. A race condition during critical data operations caused corrupted data to be saved to the cloud and published on the Paradex Chain. This resulted in some market funding indices being reset to zero, causing abnormal gains and losses and triggering liquidations across multiple markets.
In response, Paradex temporarily suspended platform access, canceled all open orders except for take-profit and stop-loss orders, and rolled back the blockchain to a snapshot taken before the maintenance window began. Previously, Paradex had been temporarily unavailable due to the rollback of the chain state during database maintenance.
