Optimism Retro Funding Batch Distributor

WHAT IT DOES

Optimism Retro Funding Batch Distributor enables you to distribute retroactive funding tokens to recipients on Optimism 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 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 sending. All recipient addresses and amounts are validated before submission, and the tool constructs the batch transaction with proper nonce management. The tool is specifically configured for Optimism through the BotGentz sender contract registry, making it ideal for retroactive public goods funding, project grants, and ecosystem contribution rewards.

HOW TO USE

Connect your wallet to Optimism. Paste the funding token contract address and your recipient list (wallet addresses and funding 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 funding amount, checks your token balance and current allowance, and displays a detailed preview table. Review the summary showing total funding, number of recipients, current allowance, contract fee, sender contract address, and owner. If allowance is insufficient, click "Approve Sender" to submit the approval transaction. Once approved, click "Send Funding" to submit the distribution transaction. The built-in status tracker monitors progress for both approval and send steps, providing clear confirmation for each.

ADAPTIVE RPC CHUNKING WITH LIVE CONTRACT VERIFICATION

The tool reads token decimals, balances, and allowances through Optimism RPC calls. Since Optimism has specific rate limits and response characteristics as an L2, the tool implements adaptive chunking with exponential backoff for balance checks. The sender contract address is looked up from the BotGentz registry for Optimism (chain 10) specifically, 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 (funding 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, not an unlimited amount. All batch transfers are sent sequentially and awaited to avoid nonce conflicts. Failed recipient checks are retried with longer delays while other chunks continue processing, ensuring reliable completion even with large recipient lists.

WHAT IT CANNOT SEE

This tool cannot verify original recipient eligibility, confirm funding entitlement amounts, or validate off-chain project impact or contribution records. It does not perform KYC checks, validate that recipients are authorized to receive funding, or confirm that funding 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 funding amounts based on their own project records.

PLEASE NOTE

This tool is built exclusively for Optimism and standard ERC20 token funding. It uses the BotGentz batch sender contract registry for chain 10. The tool does not support native ETH transfers, non-standard token types like ERC721 or ERC1155, or other networks. Always verify the funding token contract address and the sender contract address manually before executing any approval or distribution. This tool is provided free of charge and without warranty; users are responsible for confirming all transaction parameters before signing.
