Timeline
A database migration / pricing-data error on Paradex briefly priced BTC at zero during maintenance, triggering mass unintended liquidations across perpetual markets.
Paradex rolled back chain state to a prior block after the pricing-data incident, a rare and controversial response to a technical failure in a decentralized perpetuals platform.
Paradex said it refunded about USD 650,000 to around 200 users after the maintenance-related bug and unintended liquidations.
