Free Mint Gas-Only Optimizer

WHAT IT DOES

Free Mint Gas-Only Optimizer watches the current page for free mint (gas-only) opportunities, reads the current gas price via eth_gasPrice and the mint contract's state via eth_call, calculates the optimal gas price and timing to minimize gas costs, and triggers a mint transaction when the gas price is below a user-defined threshold, with configurable gas settings and transaction confirmation tracking. It helps you mint NFTs or tokens at the lowest possible cost.

WHERE IT RUNS

This tool operates as a userscript within the BotGentz extension framework, running directly in your browser on any website. It works on any EVM-compatible blockchain page—Ethereum, Polygon, Arbitrum, Optimism, and more—where free mint contracts are deployed. The tool integrates seamlessly into your workflow, appearing as a draggable panel that stays accessible as you monitor gas prices and mint opportunities.

HOW TO USE

Enter the mint contract address, mint function name, and any function parameters in the "Mint Setup" section. Configure your gas optimization settings: set the gas price threshold (in Gwei) that triggers a mint, the max gas price cap, gas limit, maximum number of mints, and refresh interval. Toggle mint state checking and auto-confirm on or off. Click "Connect & Start Optimizer" to connect your real wallet extension, which will begin monitoring gas prices and mint state at your specified interval. The panel displays the current gas price, mint count, and status updates. When the gas price drops below the threshold and the mint is available, the tool automatically triggers the mint transaction. Use "Check Now" for an immediate check, "Reset Counter" to reset the mint count, or "Stop Optimizer" to disconnect.

TECHNICAL OPERATION

Free Mint Gas-Only Optimizer uses raw JSON-RPC calls via window.ethereum.request() to interact with the blockchain. It loads ethers at runtime using a simple script tag injection for ABI encoding and contract interactions. The tool reads the current gas price using eth_gasPrice. It checks the mint contract's state using eth_call with view functions like mintAvailable, canMint, isMintLive, getMintState, or mintActive. When the gas price is below the user-defined threshold and the mint is available, the tool constructs and submits a mint transaction using eth_sendTransaction. It uses receipt.effectiveGasPrice for accurate gas cost tracking. The tool enforces a maximum gas price cap and a maximum number of mints to prevent overpaying and duplicate mints. The panel updates with the current gas price and mint status in real-time.

THE PANEL

The Free Mint Gas-Only Optimizer panel is fully draggable and remembers its position between sessions using GM_setValue. It snaps to the edge of the viewport for a clean interface and can be collapsed to a small icon when not in use. The panel is resizable to accommodate longer content. Press Escape to quickly close or collapse the panel. The design is optimized for productivity with a dark theme, clear visual hierarchy, and responsive controls that adapt to your workflow.

PLEASE NOTE

This tool requires the free BotGentz extension installed in your browser and a real EVM wallet extension (MetaMask, Rabby, etc.) already installed. EVM chains only—this does not work on non-EVM blockchains. The tool cannot read mint availability if the contract does not expose a view function, cannot predict gas price movements, cannot guarantee transaction inclusion if gas prices spike, cannot execute if the user lacks sufficient gas tokens, and cannot mint if the mint is closed or sold out. No private keys are stored or transmitted—all signing happens directly through your wallet extension. Always verify the contract address and mint function before starting the optimizer.
