Co-op Patronage Batch Distributor (Any L2)

WHAT IT DOES

Co-op Patronage Batch Distributor (Any L2) is a specialised blockchain audit tool that enables project teams and cooperative administrators to prepare and verify batch patronage distributions across any L2 network. It reads on-chain patronage 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 co-op patronage contract records, including cooperative name and total distributed amounts, providing a consolidated view of the proposed patronage 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 patronage 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 co-op patronage contract address, optionally specify a token contract address (leave blank for native currency), and a list of member addresses with their patronage amounts (format: address,amount — one per line). Click the scan button — the tool will read the patronage 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 patronage amounts and current balance columns. You can then use this data to prepare your co-op patronage 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 patronage 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 cooperativeName and totalDistributed via standard co-op patronage contract interfaces. For each member, it fetches the current balance to show the pre-patronage state. The tool parses patronage 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 co-op patronage eligibility. It does not confirm whether members are entitled to patronage distributions based on cooperative membership or patronage records. It cannot validate patronage entitlement amounts — these must be provided by the cooperative administrator based on their own records. The tool has no access to off-chain membership data, patronage records, or private decision-making records. It cannot determine whether the patronage plan is compliant with cooperative 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 patronage contract address you provide should implement standard co-op patronage distribution interfaces. Always verify the member list and patronage 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.
