Incident Post-Mortem - Oct 10-11**
What Happened
On `Oct 10-11`, extreme volatility and the subsequent flash crash led to a large number of concurrent liquidations on the platform in a short period of time. This led to a large, sudden accumulation of positions on the GigaLiquidator (GL). Typically the GL unwinds quickly, but severe on-chain transaction backlog slowed unwinds until chain max-position and event limits were hit, halting GL trading. As a result, subsequent GL trades were busted on-chain. Trade busts are rare, but when they occur, affected accounts temporarily enter resync mode to correct chain vs account state—during this period, impacted users couldn’t open/close positions. Busts also briefly worsened the backlog and created additional downstream contagion, thought it only affected a small number of users.
Immediate Response
We activated Cairo Native (live on Testnet for several months) which roughly doubled our throughput instantly and cleared the backlog within an hour. We then settled all Perp Options to shrink GL poisitions, after which the GL resumed normal operation. Given unexpected GL PnL moves from both correct and incorrect liquidations, we temporarily reserved GL PnL pending an audit to ensure fairness for both depositors and users. We reduced the TVL cap to pause new deposits and prevent opportunistic capture of the pending redistribution. BTC and ETH options were relisted soon after, and the platform returned to normal operation within a few hours.
It is worth noting that despite heavy chain congestion, the platform stayed operational and did not trigger socialized loss backstops. Paradex does not implement Auto-Deleveraging (ADL)—common on many CEXs/DEXs—because it breaks cross-platform hedges and adds unpredictability to risk management. In cross-margin systems, there’s also no guarantee of finding profitable ADL counterparties without amplifying liquidations. While not perfect, socialized loss is, in our view, the less harmful user experience. We’ll publish deeper design notes on Socialized Loss vs ADL soon.
Resolution
The GL audit was completed on Oct 14. We credited `$604,225.4`8 back to all Gigavault depositors—including those who had withdrawn and technically forfeited PnL—and allocated `$160,182.13` was reserved for incorrect liquidations, which has been distributed to affected users. The GV TVL cap has been restored to $60M with new deposits re-enabled, and options settlement fees were refunded given the short-notice delisting.
Following the learnings from the incident, we have optimized chain logic to support much higher position limits and optimized cloud-side position-limit checks to block trades before chain limits are hit, preventing trade busts. We also increased account-resync frequency for faster state convergence, and permanently enabled Cairo Native on-chain, delivering significant, sustained throughput improvements.
Final notes
Despite the scale of the contagion in the market, this was by and large a significantly less severe outcome for our users and the exchange. The platform remained operational and no socialized loss backstops were triggered. The scaling improvements we shipped quickly after the Sep 30 incident materially reduced congestion on Oct 10—proof that in crypto you must move fast and fix things; repeating the same mistake can be fatal.
Thank you to the community for the patience, feedback, and encouragement during the chaos. The culture we’re building together is special—and we feel it every time you show up for us ❤️
Your daily reminder that Paradex is the best place for retail to trade the majors for both small and larger tickets
Small Tickets
* BTC, ETH, SOL books will actually improve your price vs mid (due to crossed orderbooks enabled by RPI)
Large Tickets
* SOL - we are ~2-3x better than Binance, Bybit and Hyperliquid
* ETH - very competitive with over $200k two sided
* BTC - work in progress, but expecting significantly more size here within ~1 week
