Cross-L2 Stablecoin Batch Sender Across Arbitrum, Base, Optimism

WHAT IT DOES

Cross-L2 Stablecoin Batch Sender enables you to distribute stablecoins—USDC, USDT, or DAI—to dozens or hundreds of recipients on Arbitrum, Base, or Optimism in a single blockchain transaction. Instead of sending individual stablecoin transfers one by one and paying gas fees for each, this tool aggregates all recipient addresses and amounts into a batched call to a verified multi-send contract. It reads your stablecoin balance, fetches the token's decimals and symbol, calculates the total amount required, and presents a clear review screen before you sign. The contract dispatches all transfers atomically—either all succeed or none do—saving you gas and time compared to manual bulk sending. This is ideal for payroll, grants, community rewards, stablecoin distribution events, or any scenario requiring efficient stablecoin transfers across the three major L2s. The tool automatically detects which chain you are on and uses the corresponding BotGentz sender contract.

HOW TO USE

Connect your EVM wallet (any wallet that supports Arbitrum, Base, or Optimism via the BotGentz bridge). Enter the stablecoin token address you wish to send—USDC, USDT, or DAI. The tool does not hardcode any token addresses; you provide the correct address for your chosen stablecoin on your chosen chain. In the recipients text area, paste one address and amount per line, separated by a comma (e.g., 0x111...,10.5). Amounts are interpreted in token units—the tool reads the token's decimals automatically so you do not need to compute wei. The review card then shows the token symbol, recipient count, total amount to send, the live protocol fee (fetched from the contract in the chain's native gas token), the sender contract address, the contract owner, your current stablecoin balance, and your current allowance for the sender contract. If you have sufficient balance and allowance (or if approval is needed), the Send batch button becomes active. If allowance is insufficient, clicking Send first triggers an approve transaction for the exact total amount (never unlimited). After approval, you sign the batch send transaction. A progress bar tracks submission and confirmation, and you get a link to the transaction on the appropriate block explorer (Arbiscan, Basescan, or Optimistic Etherscan).

TECHNICAL MECHANISM

This tool uses the BotGentz shared bulk-send registry (BULKSEND) which maps each supported chain and ERC standard to a verified multi-send contract address. For Arbitrum (chainId 42161), Base (chainId 8453), and Optimism (chainId 10), the registry provides the ERC-20 sender address. The contract exposes fee() and owner() view functions—both read live at every use to avoid stale values. The sendERC20 function accepts the token address, an array of recipient addresses, an array of amounts in wei (with the token's native decimal places), and a feeAmount which must be paid as native gas token value alongside the call. The tool computes totalWei = sum(amounts) by aggregating all recipient amounts, checks your stablecoin balance and allowance, and if allowance is insufficient, performs an ERC-20 approve() for the exact totalWei (never unlimited). It then invokes sendERC20 with the fee attached as msg.value. The transaction reverts if the fee is underpaid, if any recipient address is invalid, if the stablecoin balance is insufficient, or if the token contract reverts. All sends are batched atomically in one contract call, ensuring either the entire batch completes or the whole transaction reverts—no partial sends. The tool is chain-aware and uses the correct sender contract for the chain you are currently connected to.

WHAT IT CANNOT SEE

This tool cannot send across chains in one transaction—each batch send is limited to the chain the wallet is currently connected to. It is limited to stablecoins on Arbitrum, Base, and Optimism only. It cannot detect token tax/fee-on-transfer dynamics for non-standard token implementations; such tokens will likely revert because the contract transfers fixed amounts. It cannot recover incorrectly entered recipient addresses—if an address is malformed, the contract reverts. The tool does not estimate gas costs beyond the protocol fee; gas is paid separately by your wallet. It does not validate that you have enough native gas token to cover both the protocol fee and the transaction gas. It does not scan transaction history or logs—it only reads current balance and allowance state. It cannot detect if the token contract is paused or has transfer restrictions—such conditions would cause the transaction to revert. This tool is not a cross-chain bridge; it operates per-chain only.

PLEASE NOTE

This tool only works on Arbitrum (chainId 42161), Base (chainId 8453), and Optimism (chainId 10). Your wallet must be connected via the BotGentz bridge. The protocol fee is set by the contract owner and is displayed before you sign—always review it. Stablecoin decimals are auto-detected; amounts use standard decimal notation. Remember that gas costs are paid in the chain's native token (ETH on all three chains) on top of the protocol fee—always leave a small buffer in your wallet for gas. The batch size is limited by the block gas limit; very large lists may need to be split manually. This is a DeFi tool for efficient stablecoin distribution—double-check every recipient address and amount before signing.
