Launching an NFT collection

• Buburuza supports scalable NFT deployment with low BUBU fees and full EVM compatibility. Follow these steps to create and deploy your first NFT.

  1. Write Your ERC-721 Smart Contract

  Using OpenZeppelin’s ERC-721 implementation:

  // SPDX-License-Identifier: MIT
  pragma solidity ^0.8.9;
  
  import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
  import "@openzeppelin/contracts/access/Ownable.sol";
  
  contract BubNFT is ERC721, Ownable {
      uint256 public nextTokenId;
  
      constructor() ERC721("BuburuzaNFT", "BUBNFT") {}
  
      function mint(address to) external onlyOwner {
          _safeMint(to, nextTokenId);
          nextTokenId++;
      }
  }

  Explanation:

  • BubNFT is the NFT contract with name "BuburuzaNFT" and symbol "BUBNFT".

  • mint function allows the contract owner to mint NFTs to any address.

  • nextTokenId keeps track of sequential token IDs.

  2. Set Up Your Development Environment

  You’ll need:

  • Remix IDE (https://remix.ethereum.org)

  • MetaMask wallet connected to Buburuza Testnet

  • Test BUBU tokens to pay for gas fees

  3. Compile the Contract

  1. Open Remix → Create a new file BubNFT.sol

  2. Paste the contract code above

  3. Go to Solidity Compiler tab → select 0.8.9 or above → Compile

  4. Deploy the Contract

  1. Go to Deploy & Run Transactions tab in Remix

  2. Environment → Injected Web3 (connects to MetaMask)

  3. Ensure MetaMask is on Buburuza Testnet

  4. Click Deploy → confirm transaction in MetaMask

  5. After deployment, Remix will show the contract address

  5. Mint Your First NFT

  1. In Remix, under Deployed Contracts, expand BubNFT

  2. Call mint(<recipient_address>) → transaction confirmed in MetaMask

  3. NFT is minted to the recipient address; token ID increments automatically

  6. Verify and Interact

  • Verify the contract on Buburuza Explorer

  • Interact via Read Contract / Write Contract tabs

  • View NFT ownership, metadata, and transactions on-chain

  Best Practices

  • Use base URI for metadata if deploying multiple NFTs

  • For public minting, add payment logic (payable function)

  • Integrate with IPFS or decentralized storage for NFT assets

  • Test thoroughly on Buburuza Testnet before mainnet deployment
