Multisig Wallet Checker

WHAT IT DOES

Multisig Wallet Checker provides a comprehensive view of any Gnosis Safe-style multisig wallet on EVM chains. Enter a wallet address, and the tool fetches the contract state including the list of owners, threshold (number of confirmations required), nonce (transaction count), pending transaction count, and identifies whether your connected wallet is an owner. The tool displays the owners list with visual indicators showing which addresses are owners and which one is you (if connected). This is essential for auditing multisig wallets, verifying that the owner list matches expectations, checking confirmation thresholds, and monitoring pending transactions that require action.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Ensure you are on the same network as the multisig wallet — Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, or any EVM chain. Enter the multisig wallet address in the input field. Click "Check wallet" to fetch the contract state. The tool reads the owners list, threshold, nonce, and pending transaction count from the contract. Results are displayed with the wallet address (with block explorer link), wallet type (Gnosis Safe or custom), owners list with ownership indicators, threshold, nonce, pending transaction count, and a list of pending transactions (if any). If your connected wallet is an owner, it will be highlighted with a "YOU" badge.

TECHNICAL MECHANISM

The tool uses ethers.js to interact with the multisig contract through your wallet provider. It first checks if the address is a contract by fetching its bytecode. It then attempts to read the contract state using the Gnosis Safe ABI, which includes functions like getOwners() (or owners()), getThreshold() (or threshold()), nonce(), and getTransactionCount(). The tool attempts both the standard get* versions and the direct view versions for compatibility across Safe versions. Owners are displayed with a badge indicating whether each is an owner, and if your connected wallet is in the list, it is highlighted. Pending transaction detection uses the transaction count and confirmation data from the contract. All data is fetched directly from the blockchain — no external APIs or third-party services are used.

WHAT IT CANNOT SEE

The tool cannot detect multisig wallets that use non-standard implementations (custom multisig contracts, different event signatures, or non-Gnosis Safe patterns) — it is designed for Gnosis Safe wallets and may fail or return incomplete data for custom multisig implementations. It cannot access off-chain signatures or EIP-1271 signature data — only on-chain confirmation counts are available. It cannot verify whether a pending transaction will execute successfully without simulating the transaction execution. It cannot detect malicious or pending transactions that are not properly recorded in the contract state — if a transaction was submitted but not recorded correctly, it will not appear. It cannot detect transactions that have been executed but not removed from the pending queue. It cannot retrieve the full calldata or details of pending transactions beyond what is stored in the contract. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively on EVM-compatible chains (Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche C-Chain, Fantom, and others). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool is designed for Gnosis Safe wallets (version 1.1.1 and later). Different multisig implementations may have different function signatures and may not be fully supported. The tool does not store any data — all reads happen live from the blockchain through your wallet provider. The tool is provided as-is with no warranty or liability. Always verify contract addresses from trusted sources.
