Multi-Wallet Airdrop Claimer

WHAT IT DOES

Multi-Wallet Airdrop Claimer watches any page for specified smart contract addresses and claim events, then connects directly to your EVM wallet extension (window.ethereum) to sign and submit claim transactions for multiple wallet addresses in sequence. It checks each wallet's eligibility, submits claims automatically or manually, and tracks the status and gas costs of every transaction—saving you hours of manual switching and repetitive claiming.

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 airdrop claim contracts are deployed. The tool integrates seamlessly into your workflow, appearing as a draggable panel that stays accessible as you monitor claim opportunities.

HOW TO USE

Add your wallet addresses in the "Wallet Setup" section (comma-separated). Enter the claim contract address and the claim function name (default: "claim") in the "Contract Settings" section. Set your gas limit and choose whether to enable auto-claim. Click "Check & Claim" to connect your real wallet extension, scan each wallet for eligibility, and submit claims automatically. Use "Check Status" to see which wallets are eligible without claiming, and "Clear All" to reset your saved settings.

TECHNICAL OPERATION

Multi-Wallet Airdrop Claimer uses raw JSON-RPC calls via window.ethereum.request() to interact with the blockchain—no external library required for basic operations. It calls eth_call to check each wallet's eligibility by sending a static call to the claim function with the wallet address as the from parameter. When auto-claim is enabled, it constructs and submits transaction requests using eth_sendTransaction. Gas costs are calculated from the receipt's effectiveGasPrice (not tx.gasPrice) for accurate post-EIP-1559 cost tracking. The tool manages nonces automatically through the wallet's internal nonce tracking and handles sequential processing to avoid rate limiting or nonce conflicts. Each wallet's eligibility and claim status is tracked in real-time through the status panel.

THE PANEL

The Multi-Wallet Airdrop Claimer 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. Always verify the contract address and function name before claiming. The tool cannot detect eligibility if the contract does not expose a view function for it, cannot bypass transaction failure if the claim reverts on-chain, and cannot claim if you do not have sufficient native gas tokens in each wallet. No private keys are stored or transmitted—all signing happens directly through your wallet extension.
