Bond Coupon Payment Batch Distributor (Ethereum L1)

WHAT IT DOES

Bond Coupon Payment Batch Distributor (Ethereum L1) is a specialised blockchain audit tool that enables project teams and bond administrators to prepare and verify batch bond coupon payments on Ethereum mainnet. It reads on-chain bond contract balances, checks token balances for multiple bondholder wallets simultaneously, fetches token decimals to ensure accurate formatting, and retrieves current gas price estimates for cost planning. The tool also queries bond coupon payment contract records, including coupon period and total distributed amounts, providing a consolidated view of the proposed coupon payment 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 coupon amounts and on-chain balances. The interface is designed for rapid auditing of large bondholder lists without requiring any on-chain transactions.

HOW TO USE

Connect your wallet to Ethereum mainnet using the built-in wallet bridge. Enter the bond coupon payment contract address, optionally specify a token contract address (leave blank for native ETH), and a list of bondholder addresses with their coupon amounts (format: address,amount — one per line). Click the scan button — the tool will read the bond contract balance, query each bondholder 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 coupon amounts and current balance columns. You can then use this data to prepare your bond coupon payment 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 bond 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 couponPeriod and totalDistributed via standard bond coupon payment contract interfaces. For each bondholder, it fetches the current balance to show the pre-payment state. The tool parses coupon 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 bond coupon payment eligibility. It does not confirm whether bondholders are entitled to coupon payments based on bond holding or coupon records. It cannot validate payment entitlement amounts — these must be provided by the bond administrator based on their own records. The tool has no access to off-chain bond holding data, coupon records, or private decision-making records. It cannot determine whether the coupon payment plan is compliant with bond 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, specifically Ethereum mainnet. It does not support non-EVM networks or L2 chains. The bond contract address you provide should implement standard bond coupon payment distribution interfaces. Always verify the bondholder list and coupon 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 connected to Ethereum mainnet before scanning.
