Arbitrum Orbit L3 DAO Contributor Batch Payout Tool

WHAT IT DOES

This tool enables DAOs, decentralized organizations, and community managers to pay contributors in a single batched transaction on Arbitrum Orbit L3 chains. Instead of sending 50 individual transactions and paying gas 50 times, you paste a list of contributor addresses and payout 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 payouts 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 DAO contributor payouts—covering developers, designers, writers, community managers, researchers, and all contributors participating in decentralized governance—but it works for any bulk payment need. Orbit's ultra-low fees and high throughput make this tool ideal for DAOs with large contributor bases, enabling cost-effective batch processing that would be prohibitive on L1.

HOW TO USE

Connect your EVM wallet via the BotGentz bridge. The tool automatically detects the connected Arbitrum Orbit 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 contributor list as one address and payout amount per line. Optionally include contributor IDs for your records. Click "Parse list" to validate addresses and preview the total payouts. The review panel shows the number of contributors, total payouts, 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 regular contributor grants, bounty payments, retroactive funding, and one-off contributions with ease on Orbit'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 payouts. 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 contributor payments where different contributors receive different assets. The batch size is limited only by block gas limits, suitable for DAOs with hundreds of contributors on Orbit's scalable infrastructure.

WHAT IT CANNOT SEE

This tool cannot verify off-chain contributor work quality, DAO proposal approvals, or contributor eligibility. It cannot prove that recipient addresses are correct, that contributors are legitimate, or that the same person is not receiving multiple payments via different identities. It cannot detect Sybil attacks or duplicate contributor identities. It cannot access private contributor payment preferences, DAO governance policies, or voting records. 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 payout list. It does not store any data; all state is in-memory and lost on reload. It cannot verify that contributors actually performed the work, that they met quality standards, or that they are eligible for payment based on DAO governance decisions. It cannot automatically import contribution data from DAO platforms or calculate payments based on governance proposals. It cannot handle multi-currency payments, tax withholdings, or compliance requirements beyond what you manually enter. It cannot verify that contributors have valid addresses, that they are not on sanctions lists, or that the payment complies with applicable regulations. It cannot enforce governance workflows, approval requirements, or payout schedules beyond what you manually enter. It cannot verify that contributor contributions were approved by the DAO, that they met proposal requirements, or that the work was reviewed. It cannot handle disputes, reversals, or clawback provisions. It cannot verify that contributors are in good standing with the DAO or that they have met participation requirements.

PLEASE NOTE

This tool works on Arbitrum Orbit L3 chains with the BotGentz bulk-sender contract deployed. Other EVM chains like Ethereum L1, Optimism, Arbitrum One, Base, Polygon, and others are supported by sibling tools—this specific tool is optimized for Orbit 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, payout amounts, and contributor eligibility before signing any transaction. For DAOs with regular contributor payments, consider implementing a formal governance process, using a multi-signature wallet, and consulting with legal advisors to ensure compliance with applicable regulations. Orbit L3's low transaction fees make this tool particularly attractive for DAOs with large contributor bases requiring frequent payments.
