Ostium Halts Trading After Oracle Exploit Drains Up to $22M
Ostium paused all trading and urged users to revoke approvals after an oracle exploit hit its OLP vault for an estimated $18M–$22M.
Ostium is down, and your funds could be at risk. The decentralized trading platform abruptly halted all trading activity after blockchain security firms flagged a live oracle-related exploit targeting its OLP liquidity vault. Estimated losses sit somewhere between $18 million and $22 million — and that range alone tells you the situation is still fluid.
The team moved fast on damage control, urging anyone with active contract approvals to revoke them immediately. If you're a user and you haven't done that yet, stop reading and go do it now.

Watch for on-chain analysis in the next 24–48 hours — that's typically when the full picture emerges and whether any funds are recoverable becomes clearer. For now, treat this as a total-loss scenario until proven otherwise.
