HAPIID Smart Contract

The HAPIID contract is a specialized ERC-721 NFT (Non-Fungible Token) contract with additional functionalities. It is built on Ethereum and primarily serves as a unique identification mechanism.

Key Features:

1. ERC-721 Compliance: Inherits from OpenZeppelin's ERC-721 standard for NFTs.
2. Enumerable: Implements the ERC721Enumerable extension for enumeration of token ownership.
3. Access Control: Utilizes OpenZeppelin's AccessControl to manage special roles like a MINTER_ROLE, which is responsible for minting new tokens.
4. Custom URI: Overrides _baseURI to provide a custom base URI (https://id.hapi.one/) for metadata.
5. Minting: Exposes a safeMint function which allows addresses with the MINTER_ROLE to securely mint new tokens.
6. Interface Support: Ensures compliance with various interfaces via supportsInterface.

Security:

The contract has a security contact specified (security@hapi.one) to report security vulnerabilities.
