[Feature Request] Role-Based Access Control (RBAC)

[kaihiroi]

Problem

I often find it challenging to manage access control in meta contracts, especially when multiple roles need to be defined. Without a clear structure for role management, it becomes difficult to ensure that only authorized users can perform sensitive operations, leading to potential security vulnerabilities.

Solution

I would like to implement Role-Based Access Control (RBAC) in the meta contract, which includes the following modifiers:

• onlyOwner: Restricts access to critical functions to the contract owner.
• onlyAdmin: Allows designated admin accounts to perform specific administrative functions.
• onlyRole: Enables custom role-based access control, allowing for more granular permissions.
  This solution will provide a clear and structured way to manage access control, ensuring that only authorized users can execute sensitive functions. Additionally, it is possible to implement onlyOwner and onlyAdmin as part of the RBAC framework, allowing for a more flexible and layered approach to access control.

Alternatives

I have considered using simpler access control mechanisms, such as a single owner or a basic whitelist. However, these alternatives do not provide the flexibility and security needed for more complex applications where multiple roles and permissions are required.

Additional context

Implementing RBAC will enhance the security of the meta contract by clearly defining who can perform what actions. This will not only protect sensitive operations but also make the contract easier to manage and audit. Additionally, it will align with best practices in meta contract development, ensuring that access control is robust and maintainable.
