Incident Overview
On February 11, 2025, OpenOcean detected an attack on its newly launched Limit Order contract on Base. The issue was immediately mitigated by pausing the affected contract and deploying a more secure implementation. User funds remain safe, and no revoke actions are needed.
(total loss: $22K) are being notified and assisted.
The exploit targeted a vulnerability in OpenOcean’s Limit Order contract on Base, but was quickly neutralized when the team paused the contract, preventing any further malicious activity. Since the proxy contract remained under OpenOcean’s control, the hacker was unable to drain additional funds. Some mistakenly interpreted the attacker’s post-exploit trading activity as further attacks, but OpenOcean confirmed that these transactions were unrelated to its contracts.

Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.
What Auditors Should Check
If you're auditing a protocol with similar architecture to OpenOcean, these are the critical security checks that could have prevented this incident (February 2025).
- Verify all logic paths related to Other are guarded by proper access controls and input validation
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
