Token Sale Refund Batch Distributor (Any L2)

WHAT IT DOES

Token Sale Refund Batch Distributor (Any L2) enables you to distribute refund tokens to multiple investor wallets across any supported EVM Layer 2 network in a single batch transaction. It reads the sender wallet's token balance, checks each recipient wallet balance, and calculates precise transfer amounts using the token's decimals. The tool fetches live gas prices, estimates total transaction cost including the batch sender contract fee, validates the chain-specific refund 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. All recipient addresses and amounts are validated before submission, and the tool constructs the batch transaction with proper nonce management.

HOW TO USE

Connect your wallet to your target L2 network (Optimism, Arbitrum, Base, Polygon, etc.). Paste the refund token contract address and your investor list (wallet addresses and allocation amounts in human-readable units, one per line) into the input fields. Click "Preview distribution" to validate the list, read token decimals, check the sender contract fee, and verify the contract owner. The tool automatically calculates total refund amount, checks your token balance and allowance, and displays a detailed preview table. Review the summary showing total refund, contract fee, sender contract address, and owner. Click "Send batch refund" to submit the transaction. The built-in status tracker monitors progress and provides clear confirmation.

ADAPTIVE RPC CHUNKING WITH LIVE CONTRACT VERIFICATION

The tool reads token decimals, balances, and allowances through Ethereum RPC calls across multiple L2 networks. Since each L2 has different rate limits and response times, the tool implements adaptive chunking with exponential backoff for balance checks. The sender contract address is looked up from the BotGentz registry per chain and standard, 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 (not per row), and the total required (refund amount + fee) is verified against the sender's token balance before any transaction is submitted. All batch transfers are sent sequentially and awaited to avoid nonce conflicts.

WHAT IT CANNOT SEE

This tool cannot verify original sale purchase eligibility, confirm refund entitlement amounts, or validate off-chain sale records. It does not perform KYC checks, validate that recipients are authorized to receive refunds, or confirm that allocation amounts match any off-chain agreement. It cannot detect if a recipient 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 recipient addresses and refund amounts.

PLEASE NOTE

This tool is built exclusively for EVM-compatible Layer 2 networks and standard ERC20 token refunds. It uses the BotGentz batch sender contract registry for each supported chain. 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 refund token contract address and the sender contract address manually before executing any batch refund. This tool is provided free of charge and without warranty; users are responsible for confirming all transaction parameters before signing.
