### Prerequisites: Enrollment dApp

This file outlines the steps to complete the prerequisites for the WBA Enrollment dApp. It involves setting up a Solana development environment, creating and managing Solana wallets, and performing basic transactions. These steps are designed to assess the ability to follow processes, execute tasks, debug errors, and ship code.

#### Steps:

1. **Create a new Keypair**

   - **Setting up**

     - Open Terminal.

     - Initialize a new Rust library using Cargo:

       ```sh

       cargo init --lib

       ```

     - Add `solana-sdk` to `Cargo.toml`:

       ```toml

       [dependencies]

       solana-sdk = "1.15.2"

       ```

     - Create functions in `src/lib.rs` for the scripts:

       ```rust

       #[cfg(test)]

       mod tests {

           use solana_sdk;

           #[test]

           fn keygen() {}

           #[test]

           fn airdrop() {}

           #[test]

           fn transfer_sol() {}

       }

       ```

   - **Generating a Keypair**

     - Generate a new Solana keypair.

     - Save the keypair in a JSON file.

2. **Import/Export to Phantom**

   - **Conversion Functions**

     - Add `bs58` to `Cargo.toml`.

     - Create convenience functions to convert between wallet formats.

3. **Claim Token Airdrop**

   - **Import and Setup**

     - Add `solana_client` to `Cargo.toml`.

     - Import Keypair, Connection, and LAMPORTS_PER_SOL.

     - Recreate the Keypair object using its private key.

     - Establish a connection to the Solana devnet.

     - Claim 2 devnet SOL tokens and log the transaction.

4. **Transfer Tokens to WBA Address**

   - **Setup Transfer**

     - Add `solana-program` to `Cargo.toml`.

     - Import necessary modules and the dev wallet.

     - Define the WBA public key.

     - Create a devnet connection.

   - **Execute Transfer**

     - Create a transaction to transfer 0.1 SOL.

     - Sign, broadcast, and confirm the transaction.

5. **Empty devnet wallet into WBA wallet**

   - **Calculate Fees and Transfer Remaining Balance**

     - Import `Message` from `solana_sdk`.

     - Get the balance of the dev wallet.

     - Calculate the transaction fee.

     - Transfer all remaining lamports minus the fee to the WBA wallet.

     - Sign, broadcast, and confirm the transaction.

6. **Submit your completion of the WBA prerequisites program**

   - **Understanding PDA and IDL**

     - Learn about Program Derived Addresses (PDA) and Interface Definition Language (IDL).

   - **Consuming an IDL in Rust**

     - Add `borsh` and `solana-idlgen` to `Cargo.toml`.

     - Create a `programs` folder in the `src` directory.

     - Create `mod.rs` and `wba_prereq.rs` files.

     - Declare the `wba_prereq` module in `mod.rs`.

     - Use the `idlgen` macro to consume the IDL in `wba_prereq.rs`.

     - Populate the optional metadata fields of the IDL.

     - Import the generated structs and methods in `lib.rs`.
