Solana: How to blow the air at a randomly generated key pair for testing?

I can provide you with an example article on how to airdrop Solana keys using a randomly generated key pair for testing purposes.

Solana Key Dropping: A Step-by-Step Guide

As a developer, you need to practice deploying and testing your blockchain applications. In this example, we will show you how to airdrop Solana Testnet using a randomly generated key pair for testing purposes.

Prerequisites

Solana: How to airdrop to a randomly generated keypair for tests?

  • Install Solana CLI (command line interface) on your computer.
  • Set up a Testnet account in Solana with the necessary credentials.

Step 1: Create a new wallet and key pair

Create a new wallet in Solana CLI:

solana key create --output json

This will create a JSON file containing your wallet’s private key and public address. We will use this private key to airdrop keys later.

Step 2: Generating Random Key Pairs for Airdrop

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

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 {

match &*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(),

vec![],

Vec::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 for key dumping 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: Keypair,

airdrop_id: Pubkey,

) -> 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(),

vec![],

Vec::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, an input/output transaction to receive the keys, and a single amount of 1 ether.

Step 4: Debiting the account

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

For example:

“`rust

use solana_sdk::debits;

fn debit_account(key_pair: Keypair, debit_amount: u64) -> Result<(), &'static str> {

let mut debits = DebitsBuilder::new();

debits.add_transaction(

TransactionBuilder::new()

.set_system_instruction_id(“debit”)

.build(),

);

debits.set_fee(1000); // 1 ETH

match &*key_pair.key.public_key.as_ref() {

Pubkey::Random => return Ok(()),

_ => (),

}

let amount = u64::from_debited_amount(debit_amount, 1e18);

debits.add_amount(amount);

let transaction_id = key_pair.public_key.as_ref().unwrap();

match debits.sign(&key_pair) {

Ok(_) => {

// Transaction completed successfully

println!
