OP Stack L3 Vesting-Attached Batch Sender

WHAT IT DOES

This tool enables organizations, DAOs, and project teams to distribute vesting-attached payments to recipients in a single batched transaction on OP Stack L3 chains. Instead of sending 50 individual transactions and paying gas 50 times, you paste a list of recipient addresses and vesting amounts, and the BotGentz bulk-sender contract distributes everything in one go. It supports ERC-20 tokens, ERC-721 NFTs, and ERC-1155 multi-tokens, plus native ETH through the same interface. The tool reads on-chain balances, verifies that your wallet holds enough of each asset to cover the total vesting distributions plus the contract's fee, and checks your transaction history to flag duplicates. It displays the contract's live fee, owner, and address before you sign anything so you know exactly what you are approving. This is designed specifically for vesting-attached payments—covering team token allocations, advisor grants, investor distributions, and any scenario where payments are subject to vesting schedules—but it works for any bulk payment need. OP Stack's low fees and modular architecture make this tool ideal for projects managing complex vesting distributions.

HOW TO USE

Connect your EVM wallet via the BotGentz bridge. The tool automatically detects the connected OP Stack L3 chain and looks up the correct bulk-sender contract from the BotGentz registry. Enter the token contract address, choose the token type (ERC-20, ERC-721, or ERC-1155), and paste your recipient list as one address and vesting amount per line. Optionally include vesting schedule details for your records. Click "Parse list" to validate addresses and preview the total vesting distribution. The review panel shows the number of recipients, total vesting, token address, and the contract fee in native ETH. When you click "Send batch," the tool performs a balance check per sender, not per row, ensuring the entire batch can complete before the first transfer. It then approves the sender contract for the exact total amount, not unlimited, and sends the batched transaction. Progress is shown throughout, including transaction confirmation. All state is in-memory and lost on reload—no data is stored. The tool handles team allocations, advisor grants, investor distributions, and milestone-based vesting with ease on OP Stack's efficient L3 infrastructure.

BULK SENDER CONTRACT MECHANISM

Unlike claim-based airdrops where each recipient pays their own gas to withdraw, this is a true bulk-send tool: the sender pays once for the entire batch. The BotGentz registry provides per-chain, per-standard contract addresses. The tool reads the fee() and owner() methods live from the contract each time—never hardcoding fees because the owner can change them. It uses the contract's sendERC20, sendERC721, and sendERC1155 methods, passing the recipient arrays, amounts or token IDs, and the required fee as msg.value. The fee covers the contract's operational costs and is separate from network gas. The tool checks balances comprehensively: native ETH balance must cover the fee, and ERC-20 balance must cover the total vesting distribution. It walks through approvals sequentially and awaits each transaction, avoiding nonce conflicts that would occur if sends were fired concurrently. Post-EIP-1559, it uses receipt.effectiveGasPrice for accurate cost reporting rather than tx.gasPrice. For chains with different log limits, it chunks reads appropriately, halving ranges on failure. The contract owner is shown so you can verify the deployer before signing. The tool also reads token decimals dynamically and supports multi-token distributions where different recipients receive different assets. The batch size is limited only by block gas limits, suitable for projects with hundreds of vesting recipients on OP Stack's scalable infrastructure.

WHAT IT CANNOT SEE

This tool cannot verify off-chain vesting schedules, cliff periods, or eligibility conditions. It cannot prove that recipient addresses are correct, that recipients are legitimate, or that the same person is not receiving multiple vesting allocations via different identities. It cannot detect Sybil attacks or duplicate recipient identities. It cannot access private recipient payment preferences, vesting policies, or contract terms. It cannot recover funds sent to wrong addresses—the blockchain is final. It cannot see past the current block, and it cannot enforce business rules beyond what is expressed in the vesting list. It does not store any data; all state is in-memory and lost on reload. It cannot verify that recipients are eligible for vesting, that they have met cliff conditions, or that they are entitled to the specified amounts based on agreements. It cannot automatically import vesting schedules from contract management systems or calculate distributions based on time-based release schedules. It cannot handle multi-phase vesting, milestone-based releases, or conditional payments beyond what you manually enter. It cannot verify that recipients have valid addresses, that they are not on sanctions lists, or that the payment complies with applicable regulations. It cannot enforce approval workflows, distribution caps, or release schedules beyond what you manually enter. It cannot verify that vesting calculations were performed correctly or that cliff periods were properly accounted for. It cannot handle disputes, reversals, or clawback provisions. It cannot verify that recipients have completed required actions or that vesting conditions have been met.

PLEASE NOTE

This tool works on OP Stack L3 chains with the BotGentz bulk-sender contract deployed. Other EVM chains like Ethereum L1, Optimism, Arbitrum, Base, Polygon, and others are supported by sibling tools—this specific tool is optimized for OP Stack L3. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. Always double-check the contract address displayed in the tool against the official BotGentz registry before sending. The tool is free and open-source; the contract fee is set by the owner and displayed live. Use at your own risk—you are responsible for verifying all addresses, vesting amounts, and recipient eligibility before signing any transaction. For projects with complex vesting structures, consider implementing a formal governance process, using a multi-signature wallet, and consulting with legal advisors to ensure compliance with applicable regulations. OP Stack L3's low transaction fees make this tool particularly attractive for projects requiring regular vesting distributions.
