NFT Mint Gas War Bidder

WHAT IT DOES

NFT Mint Gas War Bidder watches the current page for NFT mint transaction parameters and mempool activity, then automatically submits a mint transaction with a gas price that dynamically adjusts to outbid competing transactions in the mempool, with user-configurable maximum gas limits. The tool helps you secure NFT mints during competitive drops by automatically raising your gas price above competing transactions, giving you a better chance of being processed first.

WHERE IT RUNS

This tool works on any webpage that displays NFT minting information, including NFT project pages, minting dApps, marketplaces, and launchpad sites. It automatically detects contract addresses and mint prices from page content. The script runs on all websites as designated in its match patterns.

HOW TO USE

After installing the BotGentz extension, navigate to any NFT minting page. Click the NFT Mint Gas War Bidder icon in your browser toolbar or use the keyboard shortcut (Alt+G). The panel will open. Click "Connect Wallet" to connect your real EVM wallet extension—this enables transaction signing and gas price detection. Configure your maximum gas price limit in Gwei, your gas step increment (how much to increase each bid), and your maximum rebid attempts. Click "Refresh Details" to detect the contract address and mint price from the page. Click "Start Bidding" to begin the automatic bidding cycle. The tool will calculate a gas price above the current network price, submit the transaction, and automatically rebid with higher gas if competitors outbid you—up to your configured maximum. Monitor the bid status in the panel. Click "Stop Bidding" to manually halt the process at any time.

TECHNICAL SECTION — DYNAMIC GAS AUCTION ENGINE

Unlike fixed-gas mint tools that submit a single transaction at a static gas price, this tool uses a dynamic gas auction engine. It continuously monitors the current network gas price and the mempool for competing transactions targeting the same contract address. When a bid cycle is initiated, the engine calculates an initial gas price based on the current network price plus a configurable step increment. It then submits the mint transaction via eth_sendTransaction. If auto-rebid is enabled and the transaction is not confirmed within the monitoring window, the engine checks for new competing transactions in the mempool. If competitors with higher gas prices are detected, the engine automatically calculates a new gas price—again adding the step increment above the current network price—and submits a new transaction. This process continues until the transaction is confirmed, the maximum bid attempts are reached, or the gas price exceeds the user's configured maximum. This approach maximizes your chances of winning gas wars while giving you control over how much you're willing to spend.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position per site. It can snap to the left, right, top, or bottom edges, or float freely. Collapse it to a small status indicator when you need more page visibility, and expand it again with a single click. Resize it vertically or horizontally to show more details. Press Escape to close the panel instantly. All settings (max gas, gas step, max attempts, auto-rebid) are saved globally and persist across sessions.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension already installed in your browser. EVM chains only—supports Ethereum Mainnet, Polygon, Arbitrum, and Optimism. This tool signs and sends transactions via your wallet. Always review transaction details carefully before starting a bid cycle. Cannot guarantee outbidding all competitors—gas auctions can escalate unpredictably. Cannot access private mempool data (Flashbots, private relays). Cannot detect front-running attempts in private transaction pools. Cannot predict the exact gas price required to win a competitive mint. Users may still lose minting opportunities to higher bidders or private transactions. Gas limits and bid attempts are user-configurable; set conservative limits to avoid excessive gas spending. Websites change their layouts frequently; scripts may need updates, and we work to keep them current but cannot guarantee uninterrupted operation.
