Insurance Payout Batch Distributor (Any L2)

WHAT IT DOES

Insurance Payout Batch Distributor (Any L2) is a specialised blockchain audit tool that enables project teams and claims administrators to prepare and verify batch insurance payouts across any L2 network. It reads on-chain payout contract balances, checks token balances for multiple policyholder wallets simultaneously, fetches token decimals to ensure accurate formatting, and retrieves current gas price estimates for cost planning. The tool also queries insurance payout contract records, including policy name and total distributed amounts, providing a consolidated view of the proposed payout plan alongside actual on-chain holdings. All data is presented in a clean table with per-address breakdowns, making it easy to spot discrepancies between intended payout amounts and on-chain balances. The interface is designed for rapid auditing of large policyholder lists without requiring any on-chain transactions.

HOW TO USE

Connect your wallet to the appropriate L2 network using the built-in wallet bridge. Enter the insurance payout contract address, optionally specify a token contract address (leave blank for native currency), and a list of policyholder addresses with their payout amounts (format: address,amount — one per line). Click the scan button — the tool will read the payout contract balance, query each policyholder address for its current token balance, and calculate the total allocation against the contract balance. A progress bar shows real-time status, and results appear in a sortable table with payout amounts and current balance columns. You can then use this data to prepare your insurance payout distribution transaction with confidence. All operations are read-only and do not modify any state.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with the blockchain via the injected wallet provider. It performs batched eth_call requests with controlled concurrency (4 simultaneous queries) to avoid rate limits while maintaining responsiveness. For the payout contract address, it queries the total balance using the provider's getBalance method or the ERC-20 balanceOf method, and also attempts to read contract state including policyName and totalDistributed via standard insurance payout contract interfaces. For each policyholder, it fetches the current balance to show the pre-distribution state. The tool parses payout amounts, converts them using the correct decimals, and sums them to compare against the contract balance. Gas price is fetched using ethers' getFeeData(), which returns the current network fee estimate. All queries use the view/pure function pattern, meaning they consume no gas and execute instantly.

WHAT IT CANNOT SEE

This tool cannot verify insurance payout eligibility. It does not confirm whether policyholders are entitled to payouts based on insurance policies or claim records. It cannot validate payout entitlement amounts — these must be provided by the claims administrator based on their own records. The tool has no access to off-chain insurance policy data, claim records, or private decision-making records. It cannot determine whether the payout plan is compliant with policy terms or has received proper authorisation. It only reads what is publicly available on the blockchain through the contract interfaces you specify.

PLEASE NOTE

This tool is designed exclusively for EVM-compatible chains, including Optimism, Arbitrum, Base, Scroll, Mantle, Linea, and other L2 networks. It does not support non-EVM networks. The payout contract address you provide should implement standard insurance payout distribution interfaces. Always verify the policyholder list and payout amounts before relying on the scan output. The tool is read-only and does not execute transfers or modifications. Always double-check that you are on the correct network before scanning.
