Getting Started

Prerequisites

• Aptos Blockchain environment
• Move language compiler and runtime

Installation

1. Deploy the smart contract on the Aptos Blockchain.
2. Ensure that the aptos_token and other required modules are available.

Initialization

The smart contract must be initialized by an administrator. This sets up the minting pool and creates the NFT collection.

// Example initialization
admin_address = @bibi;
bibi::nft_mint::init(&admin_address);

Minting NFTs

Users can mint NFTs by invoking the mint function, providing the user's signer address and the desired count of NFTs.

// Example minting
user_signer = <user_signer_address>;
count_to_mint = 3;
bibi::nft_mint::mint(&user_signer, count_to_mint);
