Develop Anchor Smart Contract for Proposals on Solana

[sanaderi]

Description

Develop a smart contract using the Anchor framework to manage proposals on the Solana blockchain. The contract should include functionality to create, update, and delete proposals, as well as implement a voting system for the proposals.

---

Requirements

1. Create Proposal

   • Accept input: title, description, start_date, end_date, and creator (public key).
   • Generate a unique identifier for each proposal.
   • Store proposal data on-chain.

2. Update Proposal

   • Allow updating title, description, start_date, and end_date.
   • Ensure only the creator of the proposal can update it.

3. Delete Proposal

   • Allow the creator to delete their proposal.
   • Ensure that only valid, existing proposals can be deleted.

4. Vote on Proposal

   • Define vote types: For, Against, and Abstain.
   • Track votes within the proposal structure.
   • Ensure each wallet can vote only once per proposal.
   • Add logic to calculate vote totals dynamically when a new vote is cast.
   • Use Solana's program-derived addresses (PDAs) to securely manage vote data.

5. Access Control

   • Use Solana's program-derived addresses (PDAs) for secure and permissioned access.
   • Implement checks to validate the creator's identity for sensitive operations.

6. Unit Tests

   • Write comprehensive tests using Mocha or Anchor's built-in testing framework.
   • Test all operations: create, update, delete, vote, and edge cases (e.g., invalid data, unauthorized access).

---

Additional Context

• Use Rust with the Anchor framework.
• Follow Solana best practices for state management and security.
• Document all instructions, accounts, and data structures in the code for easier integration.

---

Acceptance Criteria

• Fully functional smart contract deployed to a testnet.
• All required features implemented and tested.
• Well-documented code with clear instructions for integration.
