OP Stack L3 Multi-Wallet Batch Sweeper

WHAT IT DOES

OP Stack L3 Multi-Wallet Batch Sweeper enables you to sweep ERC20 tokens from multiple source wallets to a single destination wallet on any OP Stack L3 chain in one batch transaction. It reads the token balance of each source wallet, calculates the total amount to sweep, and transfers all tokens from every source wallet to the specified destination address. The tool fetches live gas prices, estimates total transaction cost including the batch sender contract fee, validates the chain-specific sender contract address on-chain, and automatically handles token decimals for accurate amount formatting. It verifies the sender contract owner and displays the current fee before any transaction is signed. The tool reads the current token allowance and provides a dedicated approval step before batch sweeping. All source wallet addresses are validated before submission, and the tool constructs the batch transaction with proper nonce management. The tool supports all OP Stack L3 chains through the BotGentz sender contract registry.

HOW TO USE

Connect your wallet to your OP Stack L3 chain. Paste the token contract address, your destination wallet address, and your list of source wallet addresses (one per line) into the input fields. Click "Preview Sweep" to validate the list, read token decimals, check the sender contract fee, and verify the contract owner. The tool automatically reads each source wallet's token balance, calculates the total amount to sweep, and displays a detailed preview table showing each wallet and its balance. Review the summary showing total source wallets, total tokens to sweep, current allowance, contract fee, sender contract address, and owner. If allowance is insufficient, click "Approve Sender" to submit the approval transaction. Once approved, click "Sweep All" to submit the sweep transaction. The built-in status tracker monitors progress for both approval and sweep steps, providing clear confirmation for each.

ADAPTIVE RPC CHUNKING WITH LIVE BALANCE FETCHING

The tool reads token balances from each source wallet through RPC calls on OP Stack L3 chains. Since OP Stack L3 chains have specific rate limits and response characteristics, the tool implements adaptive chunking with exponential backoff for balance checks, fetching balances in parallel batches to optimize performance. The sender contract address is looked up from the BotGentz registry for the specific chain, ensuring the correct address is always used. The fee and owner are read live from the contract before every preview and transaction, preventing stale values from causing reverts. Allowance is checked against the exact total needed for the sweep, and the total required (sweep amount + fee) is verified against the sender's token balance before any transaction is submitted. The approval step ensures the sender contract is authorized to spend the exact total needed. All batch transfers are sent sequentially and awaited to avoid nonce conflicts. Failed balance checks are retried with longer delays while other chunks continue processing, ensuring reliable completion even with large source wallet lists.

WHAT IT CANNOT SEE

This tool cannot verify wallet ownership or authorization, confirm sweep eligibility, or validate off-chain wallet records. It does not perform KYC checks or validate that source wallets are authorized to be swept. It cannot detect if a source wallet is a smart contract that rejects transfers or implements custom receive logic. The tool does not check for token blacklists, frozen balances, or transfer restrictions beyond standard ERC20 compliance. It also cannot predict gas price volatility or guarantee transaction finality within any specific time frame. The tool relies entirely on the user to provide accurate source wallet addresses and destination address, and assumes the user has the authority to sweep tokens from all listed source wallets.

PLEASE NOTE

This tool is built exclusively for OP Stack L3 chains and standard ERC20 token sweeping. It uses the BotGentz batch sender contract registry for each supported chain. The tool sweeps the full balance of each source wallet—there is no option to sweep partial amounts. The tool does not support native ETH transfers, non-standard token types like ERC721 or ERC1155, or networks not in the registry. Always verify the token contract address and the sender contract address manually before executing any approval or sweep. This tool is provided free of charge and without warranty; users are responsible for confirming all transaction parameters before signing.
