What happened
Polychain-backed Arbitrum trading platform Cascade reported on 16 July 2026 that its CLS vault was exploited, with 1.34 million USDC of locked user funds drained.
The incident came barely a day after the Ostium oracle exploit on the same network, extending a run of attacks on Arbitrum-based perpetuals platforms. Cascade confirmed the drain affected user funds in the CLS vault; a full root-cause disclosure had not been published as of 17 July 2026.
