Base Builder Grant Batch Distributor

WHAT IT DOES

Base Builder Grant Batch Distributor enables you to distribute grant tokens to builders on Base in a single batch transaction. It reads the sender wallet's token balance, checks each recipient wallet balance, and calculates precise transfer amounts using the token's decimals. The tool fetches live gas prices, estimates total transaction cost including the batch sender contract fee, validates the chain-specific sender contract address on-chain, and automatically handles token decimals for accurate amount formatting. It verifies the sender contract owner and displays the current fee before any transaction is signed. The tool reads the current token allowance and provides a dedicated approval step before batch sending. All recipient addresses and amounts are validated before submission, and the tool constructs the batch transaction with proper nonce management. The tool is specifically configured for Base through the BotGentz sender contract registry, making it ideal for builder grant programs, developer funding, and ecosystem support initiatives.

HOW TO USE

Connect your wallet to Base. Paste the grant token contract address and your builder list (wallet addresses and grant amounts in human-readable units, one per line) into the input fields. Click "Preview Distribution" to validate the list, read token decimals, check the sender contract fee, and verify the contract owner. The tool automatically calculates total grant amount, checks your token balance and current allowance, and displays a detailed preview table. Review the summary showing total grants, number of builders, current allowance, contract fee, sender contract address, and owner. If allowance is insufficient, click "Approve Sender" to submit the approval transaction. Once approved, click "Send Grants" to submit the distribution transaction. The built-in status tracker monitors progress for both approval and send steps, providing clear confirmation for each.

ADAPTIVE RPC CHUNKING WITH LIVE CONTRACT VERIFICATION

The tool reads token decimals, balances, and allowances through Base RPC calls. Since Base has specific rate limits and response characteristics as an L2, the tool implements adaptive chunking with exponential backoff for balance checks. The sender contract address is looked up from the BotGentz registry for Base (chain 8453) specifically, ensuring the correct address is always used. The fee and owner are read live from the contract before every preview and transaction, preventing stale values from causing reverts. Allowance is checked against the exact total needed (not per row), and the total required (grant amount + fee) is verified against the sender's token balance before any transaction is submitted. The approval step ensures the sender contract is authorized to spend the exact total, not an unlimited amount. All batch transfers are sent sequentially and awaited to avoid nonce conflicts. Failed recipient checks are retried with longer delays while other chunks continue processing, ensuring reliable completion even with large builder lists.

WHAT IT CANNOT SEE

This tool cannot verify original builder eligibility, confirm grant entitlement amounts, or validate off-chain builder application or contribution records. It does not perform KYC checks, validate that recipients are authorized to receive grants, or confirm that grant amounts match any off-chain agreement. It cannot detect if a recipient wallet is a smart contract that rejects transfers or implements custom receive logic. The tool does not check for token blacklists, frozen balances, or transfer restrictions beyond standard ERC20 compliance. It also cannot predict gas price volatility or guarantee transaction finality within any specific time frame. The tool relies entirely on the user to provide accurate recipient addresses and grant amounts based on their own builder records.

PLEASE NOTE

This tool is built exclusively for Base and standard ERC20 token grants. It uses the BotGentz batch sender contract registry for chain 8453. The tool does not support native ETH transfers, non-standard token types like ERC721 or ERC1155, or other networks. Always verify the grant token contract address and the sender contract address manually before executing any approval or distribution. This tool is provided free of charge and without warranty; users are responsible for confirming all transaction parameters before signing.
