# BUK NFT

## BUK Protocol NFT Contract

The `BukNFTs` contract is a Solidity smart contract designed for managing dynamic asset inventory and ERC1155 token management for corresponding NFTs.

### Overview

The contract is designed with the following key components:

* **Buk Treasury**: Address of the Buk treasury contract.
* **Buk POS NFT Collection**: Name and address of the Buk POS NFT collection contract.
* **Buk Protocol**: Address of the Buk Protocol contract.
* **Token URI Mapping**: Mapping for token URI's for booked tickets.
* **Roles**: Constants for roles like Buk Protocol contract, marketplace contract, and admin.
* **Pausable:** Pausable **c**ontrols for contract

### Features

* **Role-based Access**: Different functionalities accessible by admin, marketplace, and Buk Protocol contract.
* **Token URI Management**: Functions to set and retrieve token URIs.
* **NFT Minting and Burning**: Functions to mint and burn NFTs.
* **Royalty Information**: Function to retrieve royalty information for a specific token.
* **Safe Transfers**: Functions to safely transfer NFTs.
* **Pausable :** Controls contract pause and unpause functions

### Functions

#### Public and External Functions:

* **pause**: To pause contract, only admin.
* **unpause**: To pause contract, only admin.
* **setBukProtocol**: Set the Buk Protocol Contract address.
* **setBukTreasury**: Set the treasury address.
* **setMarketplaceRole**: Set the marketplace address.
* **setBukPOSNFTRole**: Set the BukPOSNFT to the contract.
* **setURI**: Sets the URI for a specific token ID.
* **mint**: Mint a new NFT with a specific token ID, account, amount, and data.
* **burn**: Burn a specific NFT.
* **royaltyInfo**: To retrieve information about the royalties associated with a specific token.
* **safeTransferFrom**: Transfers ownership of an NFT token from one address to another.
* **safeBatchTransferFrom**: Transfers ownership of multiple NFT tokens from one address to another.

* **\_setBukTreasury**: Set the BukTreasury contract address.
* **\_setBukPOSNFTRole**: Set the role to a BukPOSNFT contract.
* **\_setURI**: Returns the URI associated with the token ID.

### Events

* **SetBukProtocol**: Emitted when Buk Protocol Address is updated.
* **SetBukTreasury**: Emitted when treasury is updated.
  * **SetMarketplace**: Emitted when marketplace role is granted.
* **SeNFTPOSContractRole**: Event to set NFT contract role.
* **SetURI**: Event to set token URI.

### Interface: IBukNFTs

The `IBukNFTs` interface provides a blueprint for the main `BukNFTs` contract. It defines the essential functions, events, and data structures that the main contract should implement.

#### Key Components:

* **Events**: Various events like `SetBukProtocol`, `SetBukTreasury`, `SetMarketplace`, etc.
* **Functions**: Functions like `setBukProtocol`, `setBukTreasury`, `setMarketplaceRole`, etc.
