Mint Eligibility Wallet Checker

WHAT IT DOES

Mint Eligibility Wallet Checker watches the current page for mint eligibility requirements, reads the connected wallet's holdings, balance, and status from the blockchain via eth_call, and checks eligibility against contract requirements (token holdings, NFT ownership, whitelist status, etc.), displaying a clear pass/fail status with details on why the wallet is eligible or not. It helps you verify if your wallet meets all minting requirements before attempting to mint.

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 mint contracts use eligibility requirements. The tool integrates seamlessly into your workflow, appearing as a draggable panel that stays accessible as you prepare to mint.

HOW TO USE

Configure your eligibility criteria in JSON format in the "Eligibility Configuration" section. You can set token balance thresholds (token address, threshold, decimals), NFT ownership (NFT contract address, minimum count), whitelist status (whitelist contract address), and native token balance (minimum ETH/MATIC). Set the refresh interval and toggle desktop notifications on or off. Click "Connect & Check Eligibility" to connect your real wallet extension, which will begin checking your wallet against the configured criteria at your specified interval. The panel displays a clear ELIGIBLE or NOT ELIGIBLE status, with a breakdown of each requirement and whether you passed or failed. Use "Check Now" for an immediate check, or "Stop Monitoring" to disconnect.

TECHNICAL OPERATION

Mint Eligibility Wallet Checker 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 token balances using balanceOf via eth_call, NFT ownership using balanceOf on the NFT contract, whitelist status using isWhitelisted or similar view functions (trying multiple common function names as fallbacks), and native token balance using eth_getBalance. The tool checks each configured criterion and displays pass/fail status for each. All criteria must be met for the wallet to be considered eligible. The tool updates the display in real-time and triggers notifications when the eligibility status changes. The configuration is stored in GM_setValue in JSON format.

THE PANEL

The Mint Eligibility Wallet Checker 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 eligibility if the contract does not expose the required view functions, cannot detect off-chain whitelist status, cannot check eligibility for contracts that require signature verification, and cannot determine eligibility for mints that are not yet live. No private keys are stored or transmitted—all data is read-only from the blockchain. Always verify the contract addresses and criteria before using the checker.
