Bitcoin price to zero
Paradex, a Starknet-based perpetual futures exchange, announced it will roll back its blockchain to block 1604710 following a database migration error. The glitch occurred shortly after the platform underwent scheduled maintenance operations. Bitcoin and other cryptocurrency prices displayed as zero on the platform, triggering automated liquidations of thousands of trader positions within seconds. Videos and reports circulating on social media showed accounts being forcibly closed as the system interpreted zero prices as catastrophic market crashes.
Paradex restricted access to its block explorer following the incident and temporarily disabled trading functions while recovery operations proceeded. The platform confirmed that all user funds remained safe despite the technical malfunction, stating « all user funds are SAFU » in a notice. Prior to the incident, Paradex processed nearly $1.6 billion in daily trades with $652 million in open interest according to DefiLlama and CoinGecko. The exchange operates as a derivatives-focused appchain using Starknet infrastructure and raised $35 million in 2021 at a $400 million valuation.
Decision contradicts decentralisation principles
The rollback will restore all user accounts to their state immediately before the database maintenance began. This action reverses every trade, position adjustment, deposit, withdrawal, and liquidation that occurred after block 1604710 regardless of validity. While improperly liquidated users will see their positions restored, any profits earned after the rollback point will also be completely erased. Rollbacks are typically considered a last resort for blockchain projects because they compromise the fundamental purpose of immutable transaction records. Decentralised systems emphasise that confirmed transactions should achieve permanence, with networks usually halting activity or applying targeted fixes instead of unwinding settled trades.
The decision has reignited debate around trust in Layer 2 DeFi infrastructure and how much operational control centralised teams retain over supposedly decentralised platforms. Flow blockchain previously encountered community resistance when proposing to roll back its chain following a $3.9 million security breach in the past. Paradex warned users about fraudulent accounts potentially impersonating official support channels during the outage period as scammers exploited the confusion.
Extended downtime and unclear timeline raise transparency concerns
It remains uncertain how many users were impacted by the error or the total value of liquidated assets across the platform. Paradex has not provided a definitive timeline for when users with funds tied up on the platform will regain full access. The team stated « given the complexities involved in recovery process we do not have an estimated time of arrival at this moment. » The maintenance period has significantly exceeded its originally estimated completion time, leaving traders unable to access positions or withdraw funds indefinitely. This incident highlights ongoing questions around risk management protocols and operational transparency on decentralised trading platforms that claim to eliminate counterparty risk.
The exchange’s decision to restrict block explorer access during the crisis prevented independent verification of on-chain activity and platform state. While Paradex emphasises self-custody eliminates exchange insolvency risks, the rollback demonstrates that technical failures can still trap user capital temporarily. The platform has promised to share additional updates as they become available but has not committed to publishing a detailed post-mortem analysis.
