Base Bridged USDC.e Batch Sender

WHAT IT DOES

Base Bridged USDC.e Batch Sender lets you distribute bridged USDC.e tokens to multiple addresses in a single batched transaction on the Base network. The tool reads your connected wallet address and chain ID, automatically selects the BotGentz sender contract for Base, and calculates the total USDC.e amount plus the current fee in native ETH. You provide a list of recipient addresses and amounts, and the tool checks your native ETH balance to ensure you can cover the fee. Each recipient receives their USDC.e in one batched transaction, saving you gas compared to sending individually.

HOW TO USE

Connect your wallet and ensure you are on the Base network. Enter the bridged USDC.e token address (default is the official Base bridged USDC.e contract). Paste your recipient list as comma-separated values (one per line: address, amount). Review the summary table showing total USDC.e, fee in ETH, and all recipients. Click "sign & send batch" to approve the token spend and execute the transaction. The batch is sent as a single transaction, minimizing gas costs on Base's low-fee environment.

TECHNICAL MECHANISM

The tool uses the BotGentz bulk sender registry, which contains verified contract addresses for each supported network. For Base (chain 8453), it fetches the correct erc20 sender contract from the registry. It reads the current fee from the sender contract's fee() method at execution time—never hardcoding a stale value, because fees are settable by the contract owner and stale fees would cause revert due to underpayment. The tool checks your native ETH balance against the total fee to ensure you have enough ETH for the contract fee and gas. Before sending, it verifies your USDC.e allowance and approves the exact total amount to the sender contract—not an unlimited allowance—then calls batchSendERC20() with the recipient array and amounts array. The sender contract processes all transfers atomically; if any transfer fails, the entire batch reverts, leaving your USDC.e untouched. Base's low gas costs and fast finality make this tool especially efficient for large batches.

WHAT IT CANNOT SEE

This tool cannot send native ETH or any token other than bridged USDC.e. It does not detect token tax, fee-on-transfer, rebasing, or deflationary mechanics—it assumes standard ERC-20 tokens where each transfer moves exactly the specified amount. It cannot recover incorrectly entered recipient addresses or amounts; you must verify your list before sending. It cannot send to contracts that reject transfers (e.g., blacklisted addresses). The tool does not simulate or estimate gas costs beyond the contract fee. Each execution is a separate transaction—there is no recurring or scheduled sending.

PLEASE NOTE

This tool only works on the Base network (EVM-compatible). It requires a web3 wallet (e.g., MetaMask) connected via the injected wallet bridge. Always double-check your recipient list and amounts before signing. The tool is free to use; only blockchain transaction fees and the BotGentz contract fee apply. USDC.e is the bridged version of USDC on Base—ensure you are using the correct token address (not native USDC) for this tool.
