Optimism OP Token Batch Distributor

WHAT IT DOES

Optimism OP Token Batch Distributor is a specialized DeFi tool that enables you to send OP tokens to hundreds of recipients in a single batched transaction. Instead of submitting individual transfers for each address, this tool aggregates all transfers into one atomic contract call on the Optimism network. You provide a list of recipient addresses and corresponding OP amounts, the tool constructs the transaction, and your wallet signs and broadcasts it. This dramatically reduces gas costs, eliminates repetitive manual work, and ensures all transfers execute together—either the entire batch succeeds, or nothing changes on-chain. It is ideal for airdrops, contributor rewards, vesting distributions, and any bulk OP token payout scenario where efficiency and cost savings matter.

HOW TO USE

Connect your Web3 wallet (MetaMask, WalletConnect, or any standard EVM wallet) to the Optimism network. Enter the OP token contract address for Optimism—this is required because the tool does not auto-detect it. Paste or upload your list of recipients in the format "address, amount" with one entry per line. Review the parsed list and the total OP to be sent. The tool fetches the current fee for using the shared batch sender contract and displays the contract address and owner for transparency. Click the send button, review the transaction in your wallet, and confirm. The wallet broadcasts the batched transaction to Optimism, and after confirmation, all OP transfers are executed atomically in the order you specified.

MECHANISM: BATCHED TRANSFER ATOMICITY AND FEE OPTIMIZATION

The tool builds a single transaction that calls the batchTransferERC20 function on a shared, audited BotGentz sender contract. For each recipient-amount pair, the tool encodes the ERC-20 transfer call and concatenates these calls into a single calldata payload. The sender contract iterates through the provided arrays of addresses and amounts, executing a transfer call for each pair. This batch execution is atomic: if any single transfer reverts—due to a blacklisted address, a contract that rejects OP, or any other reason—the entire transaction reverts, leaving no partial transfers. The user pays a small fee in native OP to the sender contract, which is read live from the contract's fee() function to ensure accuracy. The tool calculates the total OP required (all amounts plus the fee) and checks the sender's balance and allowance against this total before approval and sending. This prevents the common failure of partial approvals and ensures the transaction can complete successfully.

WHAT IT CANNOT SEE

This tool reads no on-chain data directly. It does not verify that recipient addresses are valid or that the sender has sufficient OP balance before signing. It cannot guarantee that all transfers will succeed—if one transfer fails, the entire batch reverts. It cannot detect if the OP contract has paused transfers, if the provided contract address is incorrect or inactive, or if the sender has enough native ETH for gas. It does not account for gas price fluctuations during execution or provide fallback mechanisms for mid-batch failures. It cannot ensure that the batch order is preserved if the network reorders transactions, though atomicity guarantees all-or-nothing execution. It does not verify that the OP token contract is the canonical Optimism OP token or that recipients are not blacklisted by the token contract.

PLEASE NOTE

This tool works exclusively on EVM-compatible chains, with Optimism as the primary target. It requires the user to have sufficient native ETH for gas and sufficient OP balance to cover the total amount sent plus the sender contract fee. The user is solely responsible for verifying the OP contract address, recipient addresses, and amounts before signing. Always test with a small batch first to confirm the setup is correct. The batch sender contract address is hardcoded per chain and is publicly available for verification; no third-party custody is involved—you remain in full control of your wallet and funds at all times.
