NFT Mint Gas Optimizer

WHAT IT DOES

NFT Mint Gas Optimizer monitors current network gas prices and calculates optimized gas settings for your NFT mint transactions. Choose your speed preference—Fast (higher cost, faster inclusion), Standard (balanced), or Cheap (lower cost, slower inclusion). The tool fetches live gas prices and base fees from the network, then computes optimized maxFeePerGas and priority fee values. It displays current gas price, base fee, and the optimized max fee—all in real-time. With one click, submit your mint transaction using these optimized parameters, saving you from overpaying or getting stuck with slow transactions. The tool also detects contract addresses and mint prices from the page automatically.

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 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 an 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 Mint Price" to read the contract's mint price. Choose your speed preference (Fast, Standard, or Cheap). Set optional caps: max gas price cap (Gwei) to prevent overspending, priority fee override, and gas limit buffer percentage. Click "Optimize & Mint"—the tool fetches current gas prices, calculates optimized settings, and submits the transaction with one click. The gas display updates every 10 seconds to reflect current network conditions. Use Ctrl+Shift+M to mint, Ctrl+Shift+G to refresh gas.

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 fetches gas prices using eth_gasPrice and base fees using eth_getBlockByNumber. Speed presets apply multipliers: Fast (1.5x gas price, 3.0 Gwei priority), Standard (1.1x, 1.5 Gwei), Cheap (0.8x, 0.5 Gwei). The transaction uses EIP-1559 type 2 with maxFeePerGas and maxPriorityFeePerGas. Gas estimation is performed with a configurable buffer (default 20%) applied to the estimate. The script attempts to encode the mint function using multiple signatures: mint(uint256), mint(address,uint256), and publicMint(uint256). Contract mint price reads use the price() or mintPrice() view functions via eth_call. All gas values are displayed in Gwei for readability. The wallet connection uses eth_requestAccounts and listens for accountsChanged and chainChanged events.

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. Minting costs gas in the network's native token—ensure your wallet has sufficient balance. This tool cannot predict future gas price fluctuations or guarantee transaction inclusion during sudden network congestion spikes. It cannot detect front-running or verify contract source code. Always verify the contract address independently before minting. The script does not store or share any data—all processing happens locally in your browser.
