Neptune Mutual Governance: Resolvable Contract (Resolvable.sol)

View Source: contracts/core/governance/resolution/Resolvable.sol

↗ Extends: Finalization, IResolvable ↘ Derived Contracts: Unstakable

Resolvable

Enables governance agents to resolve a contract undergoing reporting. Provides a cool-down period of 24-hours during when governance admins can perform emergency resolution to defend against governance attacks.

Functions

resolve

function resolve(bytes32 key, uint256 incidentDate) external nonpayable nonReentrant

Arguments

Name Type Description
key bytes32
incidentDate uint256
Source Code
