ERC-2612 Permit Batch Executor

WHAT IT DOES

The ERC-2612 Permit Batch Executor enables you to process multiple signed permit approvals and transfer tokens in a single coordinated flow. You specify the token address and a list of permit data (owner, spender, amount, deadline, signature). The tool validates each permit, executes the permit transactions sequentially, and then uses a bulk sender contract to distribute tokens to the specified spenders. This eliminates the need for multiple approval transactions and streamlines the process of enabling token transfers via permit-based approvals.

HOW TO USE

Connect your EVM wallet and select your network. Enter the ERC-2612 token address. In the permit data text area, list each permit on a separate line with the format: owner, spender, amount, deadline, signature. Click "Preview batch" to see the token details, total amount, permit list, sender contract information, and fee. If everything looks correct, click "Execute batch permit" — the tool will execute all permits and distribute the tokens. Progress is shown in real-time, and gas costs are calculated accurately using effectiveGasPrice.

ONE TECHNICAL SECTION — THE REAL MECHANISM

The tool interacts with ERC-2612 tokens that implement the permit() function, allowing gasless approvals. Each permit is a signed message authorizing a spender to use a specific amount of tokens from the owner. The tool parses the signature into its components (v, r, s) and calls permit() on the token contract for each entry. After all permits are executed, the tool uses the shared BotGentz bulk sender contract to distribute the tokens to the specified spenders. The sender contract charges a fee in native currency per recipient, which is read live via fee(). The tool checks the user's native balance to ensure it covers the total fee, and uses the sender's distributeERC20() function to batch transfer tokens. This provides a seamless way to convert signed permits into actual token transfers.

WHAT IT CANNOT SEE

The tool cannot guarantee permit validity or predict nonce ordering issues. It does not verify that the signatures are valid or that the permits have not been used before. It cannot detect if the token's nonce is out of order or if the permit has expired. It does not validate the owner's identity or ensure that the spender is authorized. The tool also cannot recover from failed permit executions — if one permit fails, the entire batch may fail.

PLEASE NOTE

This tool is EVM-only and supports Ethereum, Optimism, Cronos, BNB Chain, Polygon, Fantom, zkSync, Base, Arbitrum, Avalanche, and Linea. It does not support Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. Permits are signed off-chain and must be valid at the time of execution. The bulk sender contract addresses are provided by the BotGentz registry and may vary by chain. The tool is provided free and as-is; users assume full responsibility for their permit execution decisions.
