vault_manager

This is the main module of the contract, containing the program's logic.

Functions

1. initialize: Initializes the Vault Manager.
2. deposit: Allows users to deposit tokens into the vault.
3. withdraw: Allows users to withdraw tokens from the vault.

Structs

1. Initialize: Accounts required for initializing the vault manager.
2. Deposit: Accounts required for depositing tokens into the vault.
3. Withdraw: Accounts required for withdrawing tokens from the vault.

Errors

• VaultError: Custom error enum for handling insufficient funds errors.

Contract Details

Initialize

• Creates a PDA (Program Derived Address) for the token account owner.
• Initializes necessary accounts and programs.

Deposit

• Checks if the sender has sufficient funds.
• Transfers tokens from the sender's account to the vault.
• Uses Cross-Program Invocation (CPI) to interact with the SPL Token program.

Withdraw

• Checks if the vault has sufficient funds.
• Transfers tokens from the vault to the receiver's account.
• Uses CPI with signer seeds to authorize the transfer.

Building and Testing the Project

To build and test this Anchor project, follow these steps:

1. Install Anchor and its dependencies:

   npm install -g @project-serum/anchor-cli
   

2. Build the project:

   anchor build
   

3. Update the program ID in lib.rs and Anchor.toml with the new program ID generated during the build process.

4. Test the project:

   anchor test
   

5. To deploy the program to a Solana cluster (e.g., devnet):

   anchor deploy --provider.cluster devnet
   

Note: Make sure you have a Solana wallet set up and funded with SOL for deployment costs.

Additional Notes

• This contract uses the anchor_lang and anchor_spl crates for Solana program development.
• Proper error handling is implemented for insufficient funds scenarios.
• The contract uses PDAs for secure token management.
• Always ensure you have the latest version of Anchor and its dependencies installed.
