Implement Access Control Contracts

[raduciobanu22]

Objective
Authorization and permission management are foundational to smart contract security. Access control determines which addresses can execute sensitive operations like managing funds, updating system parameters, or triggering protocol-critical functions. The objective is to implement a set of contracts that allows us to manage access control in safe, easy and flexible way.

Scope of Work
Implement contracts that cover the following key access concepts:

1. Ownership

• Single account based access control for administrative actions
• Secure ownership transfer mechanism. Optional: two-step process (propose and accept)
• Ability to renounce ownership with proper safeguards

2. Role-based access control

• Support for multiple roles with hierarchical permissions
• Dynamic role assignment and revocation capabilities
• Role admin system where each role can have dedicated role managers
• Events emission for role changes and administrative actions

3. Time-lock

• Delayed execution mechanism for sensitive operations
• Configurable delay periods for different operation types
• Ability to cancel pending operations before execution
• Queue management for scheduled operations

Requirements

• Code should be efficient, modular, and compatible with Ralph's framework to allow for future expansion.
• Develop a comprehensive test suite covering unit tests, edge cases, and full integration for all core functionalities.
• Composability is critical

Hi @raduciobanu22 ,
I’d love to work on this issue. Please assign this to me, and I’ll deliver an efficient and secure PR within 1 day
This is my approach:
I will use OpenZeppelin’s Access Control framework to implement modular contracts for ownership, role-based permissions, and time-lock mechanisms.
comprehensive testing will ensure security, flexibility, and compatibility with Ralph's framework.

may i work on this issue @raduciobanu22?

This will be my first time writinng ralph contract but I already have experience with other languages with similar syntax so I will get it done.

I'd like to handle this task.

Hello,
I’m Akinshola Akinniyi, a smart contract developer specializing in security and access control. I prioritize secure access to protect funds and operations.

For ownership, I’ll implement a secure account-based control system with a two-step transfer process and safeguards against accidental ownership renouncement. For role-based access, I'll create multiple roles with hierarchical permissions, dynamic assignment, and revocation, along with event tracking for role changes.

I look forward to efficiently contributing to this project!
