Arbitrum One ARB Token Batch Distributor

WHAT IT DOES

This tool enables the batch distribution of ARB (Arbitrum governance token) to multiple recipient addresses in a single atomic transaction on Arbitrum One. It connects to your wallet via BGWallet, reads the ARB contract bytecode and verified source, fetches your current balance and allowance, and constructs a batched transfer that sends ARB tokens to each address with specified amounts. The batch executes through the BotGentz sender contract, ensuring all recipients receive their tokens simultaneously or the entire transaction reverts. This is ideal for DAO grants, contributor rewards, governance power delegation, community incentivization, token airdrops, or any scenario requiring efficient multi-recipient distribution of the native governance token of Arbitrum.

HOW TO USE

1. Connect your wallet using the "Connect" button (BGWallet integration).

2. Ensure you are on Arbitrum One (chain ID 42161) — the tool will prompt you to switch if needed.

3. Enter the ARB token contract address (defaults to the official ARB token: 0x912CE59144191C1204E64559FE8253a0e49E6548).

4. Click "Load token details" to automatically detect the token's symbol and decimals (18 on Arbitrum).

5. Paste your recipient list — one address and ARB amount per line, separated by space or comma.

6. Click "Parse & preview" to validate addresses and see a summary table.

7. Review the distributor information: your address, ARB balance, required total (including network fee), current allowance, and the batch sender contract details.

8. If allowance is insufficient, click "Approve" to authorize the sender contract to spend your ARB tokens.

9. Click "Distribute" to execute the atomic transfer. The progress bar will show transaction status.

TECHNICAL MECHANISM

The tool leverages the BotGentz multisender contract (BULKSEND registry) which implements a batched ERC-20 transfer function. It dynamically fetches the current fee and owner address from the contract (never hardcoding stale values). The approval process grants exactly the required total amount — not an unlimited allowance — enhancing security. The contract uses the `sendERC20` method, which takes arrays of recipient addresses and amounts, processes each transfer in a loop, and ensures all succeed before finalizing. The transaction includes the protocol fee as `msg.value`. The tool automatically detects ARB's 18 decimals on Arbitrum (standard ERC-20 precision), ensuring precise amount parsing and display. It validates total required funds against the sender's balance before submission, catching underfunding early. Arbitrum L2 gas mechanics are handled through the provider, with the tool estimating gas using the contract's `estimateGas` function and applying a 20% safety margin.

WHAT IT CANNOT SEE

This tool cannot guarantee recipient addresses are valid beyond basic Ethereum address format validation (0x + 40 hex characters). It does not verify if recipients are eligible for governance participation, if they have been blacklisted by the ARB contract, or if they are contracts that can receive and interact with governance tokens. The tool cannot recover from a failed batch — due to the atomic nature of the transaction, if any single transfer fails (e.g., blacklisted recipient, insufficient gas, contract revert), the entire batch reverts and no tokens are distributed to anyone. It cannot send to zero addresses or self, or exceed the block gas limit (which limits batch size). The tool does not simulate the transaction beforehand, so unexpected reverts may occur during execution. It relies entirely on the ARB contract behaving as expected — any changes to the token's logic (e.g., upgrades, pausing, blacklisting) could cause the batch to fail. The tool cannot predict the governance voting power implications of the distribution — it only transfers tokens and does not track voting weight, delegation, or proposal eligibility. It cannot detect if a token has hidden transfer fees or restrictions that would cause the distribution to fail. Arbitrum-specific considerations include sequencer dependencies and varying gas prices that may affect transaction propagation.

PLEASE NOTE

This tool is designed exclusively for Arbitrum One (chain ID 42161). It reads the chain ID and uses the BULKSEND registry to locate the appropriate sender contract (the registry includes Arbitrum at 0x956D760F8665358Ea1a9F11b82913020e5479376). The sender contract charges a fee in ETH (native gas token on Arbitrum), which is displayed before signing. Always review the fee, contract address, and owner before approving or sending. This tool is provided as-is — verify all transactions carefully, especially when distributing governance tokens which may have complex voting mechanisms, delegation requirements, or regulatory implications. Transactions on Arbitrum may have different confirmation times and gas costs compared to Ethereum L1.
