Loyalty Points Redemption Batch Sender (Any L2)

WHAT IT DOES

Loyalty Points Redemption Batch Sender (Any L2) is a specialised blockchain audit tool that enables project teams and loyalty program administrators to prepare and verify batch loyalty points redemptions across any L2 network. It reads on-chain redemption contract balances, checks token balances for multiple member wallets simultaneously, fetches token decimals to ensure accurate formatting, and retrieves current gas price estimates for cost planning. The tool also queries loyalty points redemption contract records, including program name and total redeemed amounts, providing a consolidated view of the proposed redemption 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 redemption amounts and on-chain balances. The interface is designed for rapid auditing of large member 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 loyalty points redemption contract address, optionally specify a token contract address (leave blank for native currency), and a list of member addresses with their redemption amounts (format: address,amount — one per line). Click the scan button — the tool will read the redemption contract balance, query each member 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 redemption amounts and current balance columns. You can then use this data to prepare your loyalty points redemption 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 redemption 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 programName and totalRedeemed via standard loyalty points redemption contract interfaces. For each member, it fetches the current balance to show the pre-redemption state. The tool parses redemption 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 loyalty points redemption eligibility. It does not confirm whether members are entitled to redemptions based on points accumulation or program records. It cannot validate redemption entitlement amounts — these must be provided by the program administrator based on their own records. The tool has no access to off-chain loyalty points accumulation data, program records, or private decision-making records. It cannot determine whether the redemption plan is compliant with program policies 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 redemption contract address you provide should implement standard loyalty points redemption distribution interfaces. Always verify the member list and redemption 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.
