❓What is a nonce account?

A nonce account is like a security checkpoint for transactions in Solana. In the vvaifu.fun Fair Launch method, it ensures that every transaction is:

1. Unique: It can only be used once.

2. Authorized: Only the person who created it can approve its use.

3. Secure: It prevents tampering or cheating.

How Does It Work in a vvaifu.fun Launch?

1. Creating a Nonce Account

When you prepare for a token launch, the system creates a special account for you called a nonce account.

• What it does: Think of it as a ticket machine. Every time you make a transaction, it generates a one-time ticket (nonce) to send with it.

• Why it’s safe: Only you can use this ticket because it’s linked to your wallet.

2. Using the Nonce

Before the token launch:

• The system includes this unique ticket (nonce) in your transaction.

• Once the transaction is sent, the ticket is marked as “used” and can’t be reused.

This means no one can copy your transaction and send it again.

3. Submitting the Transaction

When the launch goes live:

• The system checks your ticket (nonce) to ensure it’s valid and hasn’t been used before.

• If the ticket checks out, your transaction is processed. If not, it’s rejected.
