NFT Mint Batch Buyer

WHAT IT DOES

NFT Mint Batch Buyer lets you mint multiple NFTs in a single transaction—saving gas and time compared to minting one by one. It detects the contract's mint function automatically, reads the mint price on-chain, and calculates the total cost (mint price × quantity + gas). You specify how many NFTs to mint, and the tool submits one batched transaction with the adjusted mint amount parameter. Includes balance checks, gas estimation, and configurable gas multiplier. Perfect for collectors who want to mint multiple pieces from a collection without clicking the button repeatedly and paying separate gas fees each time.

WHERE IT RUNS

Any webpage with NFT minting activity—NFT marketplaces, project launch pages, mint dashboards, and collector portals. The script automatically detects contract addresses and mint functions from the page content, or you can paste the address manually. Works with any EVM-compatible chain (Ethereum, Polygon, Arbitrum, Optimism, etc.) as long as your wallet is connected to the correct network.

HOW TO USE

Install the script and navigate to any NFT mint page. Click "Connect Wallet" to link your MetaMask or other EVM wallet. The tool will detect the contract address automatically—verify it. Click "Fetch Contract Info" to read the mint price and available mint functions. Set the number of NFTs to mint (batch quantity) and max batch limit. The total cost updates in real-time. Optionally adjust the gas multiplier (1.0-2.0) for faster confirmation. Click "Batch Mint"—the tool estimates gas, checks your balance, and submits a single transaction minting the full quantity. Keyboard shortcut: Ctrl+Shift+B to batch mint without opening the panel.

TECHNICAL MECHANISM

The script loads ethers.js v5.7.2 dynamically via a DOM-injected script tag, then creates a Web3Provider from window.ethereum. It detects the contract address from the page or user input, and reads the mint price via price() or mintPrice() view functions. The tool constructs a contract interface with multiple mint function signatures: mint(uint256), mint(address,uint256), and publicMint(uint256). It attempts to encode each signature in order, using the first one that works. The batch transaction includes the quantity as the amount parameter, and the value is set to (mintPrice × quantity). Gas estimation is performed with a user-configurable multiplier (default 1.1x) applied to the estimate. Balance checks compare the user's ETH balance against the required value before submission. The transaction is sent via the wallet's signer, and the receipt is parsed to show the actual gas cost using effectiveGasPrice.

THE PANEL

The tool runs inside BGPanel, a lightweight UI system built into the BotGentz extension. Drag the panel by its header to reposition it anywhere on screen—it snaps to edges and remembers its position per site. Click the header to collapse the panel into a small bubble; click again to expand. Resize the panel by dragging its bottom-right corner. Press Escape at any time to close the panel. The panel stays out of your way but is always accessible via the extension's toolbar.

PLEASE NOTE

Requires the free BotGentz browser extension and a real EVM wallet extension (MetaMask, Coinbase Wallet, or any wallet that injects window.ethereum). The script supports EVM-compatible chains only. Batch minting may fail if the contract has per-wallet mint limits (e.g., max 1 per wallet) or if the total cost exceeds your balance. This tool cannot exceed gas limits or block gas limits, cannot guarantee the contract supports batch minting beyond the function's capacity, and cannot bypass per-wallet mint limits imposed by the contract. Always verify the contract address independently. The script does not store or share any data—all processing happens locally in your browser.
