A large crypto trader has lost approximately $8.2 million after attempting to build a highly leveraged long position in the ARC perpetuals market on Lighter. The position, accumulated over several days, pushed total open interest in ARC contracts to nearly $50 million, with around 600 counterparties taking the opposing side.
The trade began to unravel after ARCs price declined around Roughly $2 million of the position was liquidated through the order book. The remaining exposure was transferred into Lighter’s Liquidity Provider Pool (LLP), categorized under a higher-risk strategy to manage the imbalance.
Auto-Deleveraging Limits Liquidity Provider Losses
To contain systemic risk, the platform activated auto-deleveraging (ADL), partially closing profitable short positions to unwind the oversized long. At its peak, the LLP temporarily absorbed close to 200 million ARC tokens, valued at about $14.7 million, before further reductions as prices continued falling.
Despite the scale of the liquidation, liquidity provider losses were limited to roughly $75,000 due to the ARC market being isolated within a separate risk bucket. Short traders who held opposing positions reportedly generated profits.
Following the incident, Lighter introduced a $40 million open interest cap on ARC and shifted the market to a capped liquidity strategy with around $100,000 in allocated capital. Additional safeguards may be extended to other trading pairs as decentralized platforms face ongoing scrutiny over leverage and market manipulation risks.
