Introduction

The MintNFT smart contract is an ERC-721A-based contract optimized for gas-efficient minting of NFTs. This contract is designed to work on the Immutable X blockchain, allowing users to mint NFTs in batches of three per transaction. It ensures proper handling of minting, fund management, and metadata storage.
