Contract Functions

PermissionOverride

The PermissionOverride contract allows for overriding the permission settings of a given address for a specific function. This is useful for scenarios where you need to grant temporary or limited access to a function, even if the address doesn't normally have permission.

Version 0.1.6

PermissionOverride Contract

The PermissionOverride contract enables temporary or restricted function access for specific addresses.

Features

  • Override permissions for specific addresses and functions.
  • Manage permission overrides through dedicated functions.
  • Revoke overrides when no longer needed.

    • Usage

    To use the PermissionOverride contract, you can deploy it and interact with it using a compatible wallet or development environment. Here's a basic usage guide:

    <li>Deploy the PermissionOverride contract.</li> <li>Call the 'setOverride' function to grant an address temporary permission to execute a specific function.</li> <li>The target address can now call the overridden function.</li> <li>Use the 'revokeOverride' function to remove the granted permission when it's no longer needed.</li>

    Implementation Details

    The contract uses a mapping to store the granted overrides. Each override is associated with an address and a function selector. The contract also includes functions to manage these overrides.

    Best Practices

  • Use this contract only when absolutely necessary for temporary or limited access.
  • Ensure that the 'setOverride' and 'revokeOverride' functions are called with the correct arguments.
  • Document the purpose and duration of each override for easier maintenance.

    • Functions

    setOverride

    setOverride(address,bytes4)

    revokeOverride

    revokeOverride(address,bytes4)
