Optimism Velodrome Batch Distributor

WHAT IT DOES

This tool enables you to distribute VELO (ERC-20) payments to multiple recipients in a single batch transaction on Optimism. It reads your connected wallet address, the chain ID (must be 10), VELO token balances and decimals (18), and a list of recipient addresses with amounts. You configure the recurring distribution parameters—amount per recipient, frequency, and duration—and each execution is a separate batch transaction that you sign and send. The tool uses the shared BotGentz sender contract (0x956D760F8665358Ea1a9F11b82913020e5479376) to perform the batch transfer, charging a small fee in ETH for each batch. You must approve the sender contract for the exact total amount of VELO you intend to distribute before the batch can be executed. VELO is the native token of the Velodrome Finance DEX on Optimism with 18 decimals, and this tool handles the token's decimals automatically. On Optimism, gas costs are significantly lower than Ethereum mainnet, making this tool highly cost-effective for frequent distribution runs.

HOW TO USE

Connect your wallet (Optimism only), enter the VELO token contract address (the canonical address on Optimism is 0x956d760f8665358ea1a9f11b82913020e5479376, but you can enter any VELO-compatible ERC-20 address), and list recipients with their amounts (one per line). The tool will parse the list, show you the total amount including the contract fee, and display your VELO balance. You first approve the sender contract to spend the total VELO amount, then you send the batch. Each batch is a single signed transaction; for recurring distributions, you repeat the process on your chosen schedule. The tool does not automate scheduling—you decide when to execute each batch.

TECHNICAL MECHANISM

The batch distribution is performed by calling sendERC20Batch(address token, address[] calldata recipients, uint256[] calldata amounts) on the BotGentz sender contract. The contract iterates through the arrays and transfers the specified amounts from the caller to each recipient. The fee is read live from the contract's fee() function and must be paid in ETH as part of the transaction value. The tool checks your VELO balance and allowance against the total required (sum of amounts plus fee) before signing, preventing partial failures. All transfers are sequential within the contract, ensuring atomicity—if any transfer fails, the entire batch reverts. The tool does not cache fee or owner data; it reads them fresh each time to avoid stale values that could cause revert. VELO uses 18 decimals, and the tool automatically detects and uses the token's decimals via the standard ERC-20 decimals() function.

WHAT IT CANNOT SEE

The tool cannot send native ETH or any token standard other than ERC-20. It cannot detect token tax or fee-on-transfer dynamics for non-standard tokens; if your VELO variant deducts a fee on each transfer, the amount received by recipients will be less than specified. It cannot recover incorrectly entered recipient addresses—invalid addresses are simply skipped. It cannot send to contracts that reject transfers (e.g., blacklisted addresses). It does not validate distribution parameters (amount, frequency, duration) against token or contract constraints; you must ensure amounts are within your balance and allowance. It does not automatically execute recurring distributions; each execution is a separate batch transaction that you manually trigger. The tool assumes the user-provided token address is a standard VELO contract; it does not validate that the entered address is the canonical VELO token on Optimism. The tool is limited to Optimism only.

PLEASE NOTE

This tool works exclusively on Optimism (chainId 10). It does not support any other EVM chain. The BotGentz sender contract is hardcoded and verified; you can review its source code on Optimistic Etherscan. Always confirm the fee and contract address before signing any transaction. This tool is provided as-is; you are responsible for verifying recipient addresses and amounts.
