Blast Vesting-Attached Batch Sender

WHAT IT DOES

Blast Vesting-Attached Batch Sender lets you distribute ERC-20 tokens to multiple recipients with built-in vesting schedules in a single batched transaction on the Blast network. The tool reads your connected wallet and chain ID, automatically selects the BotGentz sender contract for Blast, and calculates the current fee in native ETH. You provide the token address, a list of recipient addresses and amounts, and vesting parameters—cliff duration, total vesting duration, and start timestamp. Each recipient receives their tokens with a vesting schedule attached, saving gas compared to creating vesting schedules individually. This is ideal for team allocations, investor distributions, or any scenario where tokens need to be locked and released over time. Blast's low fees and native yield make this tool especially efficient for large batches.

HOW TO USE

Connect your wallet and ensure you are on the Blast network (chain 81457). Enter the ERC-20 token address you want to distribute. Paste your recipient list as comma-separated values (one per line: address, amount). Enter vesting parameters: cliff duration in months, total vesting duration in months, and start timestamp (Unix time). Review the summary table showing total tokens, fee in ETH, vesting schedule, and all recipients. Click "sign & send batch" to approve the token spend and execute the transaction. The batch is sent as a single transaction, creating all vesting schedules atomically—if any schedule fails, the entire batch reverts.

TECHNICAL MECHANISM

The tool uses the BotGentz bulk sender registry to fetch the correct contract address for Blast. 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 token allowance and approves the exact total amount to the vesting contract—not an unlimited allowance—then calls the batch vesting function with the recipient array, amounts array, and vesting parameters. The vesting contract processes all schedules atomically; if any schedule creation fails, the entire batch reverts, leaving your tokens untouched. The tool automatically detects token decimals and symbol.

WHAT IT CANNOT SEE

This tool cannot send native ETH or any token other than ERC-20. 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, amounts, or vesting parameters; you must verify your list before sending. It cannot send to contracts that reject transfers. It is limited to ERC-20 tokens on Blast network only. It does not verify vesting schedule feasibility or token lockup compatibility—it assumes the vesting contract supports the parameters you provide. It does not support custom vesting curves or milestone-based unlocks. 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 Blast network (EVM-compatible, chain 81457). It requires a web3 wallet (e.g., MetaMask) connected via the injected wallet bridge. Always double-check your token address, recipient list, vesting parameters, and amounts before signing. The tool is free to use; only blockchain transaction fees and the BotGentz contract fee apply. Ensure you are using the correct token address—using the wrong token could result in loss of funds.
