Ostium, an RWA trading platform on Arbitrum, said the July 15 attack stemmed from a compromise of offchain infrastructure tied to the protocol’s pricing system, with losses exceeding $23.75 million. The team said it is now working with Mandiant, zeroShadow, Collisionless, SEAL 911, and law enforcement, while also coordinating with exchanges, bridges, and stablecoin issuers. According to Ostium, engineering efforts are currently focused on isolating and hardening the infrastructure required for a safe restart. The platform added that it will provide at least 24 hours’ notice before unfreezing trading contracts. Once trading resumes, trader positions will be marked at the reopening price, with price moves during the suspension period not affecting those positions.
