Prerequisites

• Rust and Cargo
• Solana CLI tools
• Node.js and Yarn
• Anchor Framework

Setup

1. Clone the repository:

   git clone https://github.com/solana-developers/solana-account-data-matching
   cd account-data-matching

2. Install dependencies:

   yarn install

3. Build the project:

   anchor build

4. Run tests:

   anchor test

Project Structure

• programs/account-data-matching/src/lib.rs: Main program logic for the vault system
• tests/account-data-matching.ts: Comprehensive test suite
• Anchor.toml: Anchor configuration and deployment settings
• Cargo.toml: Rust dependencies
• migrations/deploy.ts: Deployment script

Key Features

• Secure vault initialization
• Token account management
• Withdrawal functionality with proper authorization checks

Usage

1. Initialize the vault:

   await program.methods.initializeVault()
     .accounts({
       vault: vaultPDA,
       tokenAccount: tokenPDA,
       withdrawDestination: withdrawDestination,
       mint: mint,
       authority: wallet.publicKey,
     })
     .rpc()

2. Perform a withdrawal (ensure proper authorization):

   await program.methods.insecureWithdraw()
     .accounts({
       vault: vaultPDA,
       tokenAccount: tokenPDA,
       withdrawDestination: withdrawDestination,
       authority: wallet.publicKey,
