Key Highlights
- Paradex, that paragon of decentralized perfections, found itself in a quandary as its chain state was rolled back, reducing Bitcoin’s price to a ghostly $0.
- The exchange, in a fit of panic, donned cancel-only and post-only modes, like a timid mouse fleeing a cat.
- The incident, a tempest of technical hubris, reignited debates about rollbacks and the fragile dance of appchain-based DEXs.
Paradex, that sylph of decentralized perpetuals, built on Starknet’s fragile parchment, restored trading with the grace of a phoenix after a database migration error, that most insidious of digital specters, briefly priced Bitcoin at zero-a spectral mirage.
The problem, a rogue algorithm, emerged during routine database maintenance, spiraling into chaos as positions were erased by prices that never should have existed. Within hours, the team, in a moment of desperation, executed a full chain rollback, an act as controversial as it was necessary, resetting the chain to its last clean state, a veritable phoenix rising from the ashes of digital chaos.
A rare rollback in decentralized trading
In a Discord update, Paradex’s engineering leadership, those modern-day alchemists, confirmed the rollback to block 1,604,710, a timestamped relic before the maintenance window. The rollback, a surgical strike, restored all accounts to their pre-maintenance glory.
🚨BREAKING: @Starknet based perp DEX @paradex announces a chain rollback to block 1,604,710 after a database migration error briefly sent Bitcoin’s price to zero, triggering mass liquidations.

Rollbacks, that most dreaded of blockchain heresies, are generally avoided like the plague. Most protocols prefer pausing activity or applying targeted fixes. Paradex’s decision, a bold stroke, immediately drew attention across the DeFi cosmos.
“DO NOT USE@paradex if you don’t want to liquidate your btc on ‘$0’,” Raki wrote on X, as screenshots of zero-priced Bitcoin trades circulated like wildfire, a digital plague.
Gradual recovery under restricted trading
Following the rollback, Paradex, that meticulous choreographer of chaos, implemented a staged recovery:
- Cancel-only mode, where users could only close positions, like a funeral director bidding farewell to their assets.
- Post-only mode, allowing new orders without immediate execution, a dance of patience.
- Full trading, restored once system integrity was confirmed, a triumphant return to the stage.
By 09:15 BRT, the platform, that resilient phoenix, confirmed Paradex was fully operational again, a testament to human (and algorithmic) tenacity.
Voyager’s block feed, that ever-ticking metronome, showed transactions ticking through every few seconds again, a practical signal that Starknet had returned to normal, a rebirth after the storm.
Starknet under scrutiny
The incident, a tempest of technical hubris, occurred just two weeks after a separate Starknet outage, adding pressure on the network as on-chain activity continues to rise, like a feverish heartbeat.
Even so, the ecosystem, that resilient garden, keeps growing. Stablecoin supply on Starknet, that ever-expanding river, has pushed past $200 million, and DeFi trading remains active, suggesting adoption is moving faster than the underlying infrastructure, a race against time.
Starknet’s native token, STRK, hovered around $0.081, with volatility spiking after the Paradex incident, according to data from CoinMarketCap, a rollercoaster of uncertainty.
A test of trust in on-chain derivatives
Paradex, that appchain on Starknet, designed for low-latency, non-custodial derivatives trading, operates as a paragon of innovation. The platform, incubated by Paradigm (the liquidity network), previously raised $35 million from investors, a chorus of financial titans.
While the exchange’s swift communication and rollback prevented permanent losses, the incident has renewed debates over how decentralized exchanges should respond to extreme technical failures, a conundrum as old as the hills. Where lies the line between decentralization and operator control? A question as elusive as the price of Bitcoin itself.
For traders, the takeaway was clear: while on-chain derivatives offer transparency and speed, infrastructure risk remains very real, especially during moments of rapid growth-a reminder that even the grandest castles can crumble under the weight of a single error.
