A major crypto trader on the decentralized derivatives platform Lighter lost approximately 8.2 million USDC due to a leveraged long position in the ARC detailed analysis perpetuals market.

Around 18:00 ET on Wednesday, the position unwound due to a sudden drop in ARC price. A 2 million dollar portion was liquidated, and the remaining part was transferred to the Lighter Liquidity Provider pool (LLP). The platform managed the risk by triggering the auto-deleveraging (ADL) mechanism under the high-risk strategy; the LLP absorbed 200 million ARC (approximately 14.7 million dollars) at one point. This shows that ADL is a critical tool protecting liquidity providers.
Details of the ARC Perpetual Liquidation
- Position Size: 50 million dollar long, 600+ counterparties
- Loss: 8.2 million USDC for the trader
- LLP Impact: 200M ARC absorption, losses limited to 75 thousand $
- Winners: Short position holders made big profits
Liquidity provider losses were limited to 75 thousand dollars thanks to risk limits. After the incident, Lighter introduced a 40 million dollar open position limit for ARC futures, moved the pair to a capped liquidity strategy with 100 thousand USDC capital, and added automatic transition to ADL if it depletes. Similar limits may be extended to other assets.
