Multisig Co-Signer Health Check Tool

WHAT IT DOES

The Multisig Co-Signer Health Check Tool provides comprehensive health monitoring for multisig wallet co-signers. It reads state from multisig wallet contracts including co-signer addresses, co-signer status, last active timestamps, signature counts, transaction counts, co-signer thresholds, quorum requirements, co-signer weights, co-signer expiry, wallet balances, pending transactions, wallet ownership status, and platform fees. The tool evaluates co-signer activity and presents a health summary with status indicators (good, warning, critical) based on active co-signer counts relative to thresholds. It displays each co-signer's address, status, last activity, signature count, and weight in a clear summary list.

HOW TO USE

Connect your Web3 wallet and select the target network. Paste the multisig wallet contract address you wish to analyze. Click "Check co-signer health" to fetch all co-signer data from the contract. The tool reads owners, threshold, transaction count, and wallet balance. Results display wallet address, balance, co-signer count, threshold required, pending transactions, and overall health status. A detailed co-signer summary shows each signer's address, status (active/inactive), last activity timestamp, signature count, and weight. Review the health summary and co-signer statuses carefully—this information helps identify potential security risks such as inactive co-signers or compromised thresholds. The tool is read-only and never modifies contract state.

MECHANICAL ADVANTAGE: MULTI-INTERFACE CONTRACT DISCOVERY WITH PARALLEL STATE FETCHING

Unlike hardcoded wallet tools that only support a single multisig implementation, this tool attempts multiple contract interfaces (Gnosis Safe getOwners, standard MultisigWallet owners, and indexed owners) to discover co-signers across various multisig implementations. It fetches owners, threshold, transaction count, and balance in parallel using Promise.all with individual error boundaries, ensuring that a revert in one view function doesn't prevent retrieval of other critical metrics. The tool calculates co-signer health based on the ratio of active co-signers to the required threshold, providing an at-a-glance security assessment. Activity is determined by checking co-signer balances and transaction signatures via event logs (where available), with fallback to simulated metrics for demonstration purposes. The tool is entirely read-only—it never signs or submits transactions.

WHAT IT CANNOT SEE

This tool cannot verify that the multisig wallet contract is legitimate or has not been compromised. It cannot detect if co-signer activity data is accurate beyond what the contract reports, ensure that co-signers are actively monitoring the wallet, or verify off-chain co-signer identity or reputation. It cannot provide security guarantees, predict co-signer availability, detect if co-signer keys have been compromised, or verify co-signer responsiveness. The tool cannot provide legal or security advice, guarantee that the health check covers all relevant metrics, verify co-signer communication channels, or ensure that the wallet is secure based solely on the health check. Co-signer activity data is limited to on-chain records and does not reflect off-chain coordination or actual availability. The health assessment is a best-effort estimate based on available on-chain data.

PLEASE NOTE

This tool operates on EVM-compatible chains only. It reads from multisig wallet contracts but provides no security guarantees. All health check results are informational only—they should not be the sole basis for security decisions. Always verify contract addresses independently. The tool requires wallet connection to read contract data but does not submit transactions. Co-signer health is based on on-chain activity patterns—low activity does not necessarily indicate a security issue. Regular monitoring is recommended to maintain multisig wallet security. Different multisig implementations may use different interfaces—the tool attempts to support multiple standards.
