Hello there,

I’d like to work on this task #76 — Emergency Override in Oracle, a critical safety mechanism.

With strong experience writing secure smart contracts, I will implement a robust emergency override that:

Requires multi-sig approval (2-of-3 admins) for any market outcome override

Enforces a cooldown period to prevent rapid-fire or accidental changes

Emits a clear EmergencyOverride event with justification hash for transparency and auditability

Includes thorough unit tests covering normal operation, multi-sig enforcement, cooldown handling, and edge cases

I’ll ensure deterministic, tamper-resistant logic and strong on-chain safety guarantees, delivering a production-ready mechanism to protect market integrity

I’m comfortable working with smart contract state management and access control patterns. For this issue, I would implement a strict 2-of-3 multi-signature requirement, ensure the override can safely update any market outcome, emit a well-structured EmergencyOverride event with a justification hash for transparency, and add a cooldown mechanism to prevent abuse. I would also include thorough unit tests covering signature validation, cooldown enforcement, and edge cases.
