Assignment 4: Native Solana Program for Account Management

Overview

This assignment implements a native Solana program that allows users to initialize an account, deposit SOL into it, and withdraw 10% of the deposited SOL at a given time. The program is written in Rust and utilizes the Solana Program Library.

Features

1. Initialize a new account
2. Deposit SOL into the account
3. Withdraw 10% of the deposited SOL at a given time

Program Structure

The main program logic is contained in lib.rs and consists of the following key components:

• process_instruction: The main entry point of the program
• initialize_vault: Creates and initializes a new vault account
• deposit_tokens: Allows users to deposit SOL into their vault
• withdraw_tokens: Enables withdrawal of 10% of the deposited SOL

How to Use

1. Deploy the program to a Solana cluster (devnet or localhost)
2. Use a client application to interact with the program:
   • Initialize a new vault
   • Deposit SOL into the vault
   • Withdraw 10% of the deposited SOL (subject to time restrictions)

Important Notes

• This program uses a PDA (Program Derived Address) to create and manage vault accounts
• The withdrawal function is restricted to 10% of the deposited amount
• Proper error handling is implemented to ensure secure operations

Security Considerations

• Ensure that only the account owner can withdraw funds
• Implement proper checks for account ownership and balances
• Use secure random number generation for any time-based restrictions
