A JSON file will be created containing your wallet’s private key and public address. We will use this private key to perform the key airdrop later.

Step 2: Generate random key pairs for Airdrop

To generate random key pairs, we can use the module "solana_sdk::keypair".

use solana_sdk::signer::{Keyid, Signer};
use solana_sdk::sysvar::Pubkey;
use solana_sdk::transaction::{TransactionId, TransactionOutput};
use solana_sdk::keypair::{Keypair, KeypairBuilder};
fn generate_airdrop_keypair() -> (Keypair, Keypair) {
let mut key_pair = KeypairBuilder::new().generate_keyid().unwrap();
while true {
matches &*key_pair.public_key.as_ref() {
Pubkey::Random => break,
_ => (),
}
}
let wallet_id = Keyid::from_bytes(&key_pair.key.id).unwrap();
let wallet_out = TransactionOutput::new(
Keyid::from_bytes(&wallet_id).unwrap(),
SolanaId::default(),
old![],
old::new(),
);
(key_pair, wallet_out)
}

This function generates a new random key pair and creates a transaction output with the public key of the key pair. We will use this output to use the airdrop keys later.

Step 3: Create an airdrop transaction

Create an airdrop transaction using the Transaction structure.

use solana_sdk::transaction::{Transaction, TransactionBuilder};
fn create_airdrop_transaction(
public_key_pair: key pair,
airdrop_id: public key,
) -> Transaction {
let mut tx = TransactionBuilder::new()
.set_system_instruction_id("airdrop")
.build();
tx.add_input_output_transaction(
TransactionOutput::new(
public_key_pair.public_key.as_ref(),
SolanaId::default(),
old![],
old::new(),
),
);
tx.add_amount(1e18); // 1 ether
tx.sign(&public_key_pair)
}

This function creates a new transaction with the public key of the key pair, the input and output transaction keys to receive, and one amount of ether.

Step 4: Debit the Account

To debit an account on Solana Testnet, we need to use the solana_sdk::debits module. More information about account debits can be found in the [Solana SDK documentation](

For example:
