Multisig Nonce Recovery Tool

WHAT IT DOES

This tool enables multisig wallet administrators and signers to identify and recover from stuck nonce scenarios that prevent the multisig from processing new transactions. In a multisig wallet, each transaction is assigned a sequential nonce. If a transaction at a particular nonce becomes stuck (due to failed execution, insufficient gas, or other issues), all subsequent transactions with higher nonces are blocked until the stuck transaction is resolved. This tool helps detect the stuck nonce, recover it by clearing or skipping the stuck transaction, and restore normal multisig operation. It connects to your wallet and reads the multisig contract address, current nonce, pending transactions count, stuck transaction nonce, transaction history, signers list, recovery status, and timestamps. The tool signs and submits transactions to recover stuck nonces, execute pending transactions, clear stuck transactions, update nonce state, record recovery metadata, and emit recovery events.

HOW TO USE

1. Connect your wallet using the wallet bridge (supports MetaMask, WalletConnect, and other EVM-compatible wallets).

2. Select the target network that matches your multisig contract deployment.

3. Enter the multisig contract address and click "load contract" to initialize the connection.

4. Click "fetch nonce status" to retrieve the current nonce, pending transactions count, transaction history, and identify any stuck nonces.

5. The tool automatically detects stuck nonces by scanning the transaction history for gaps — if nonce 2 is missing while nonce 0 and 1 exist, nonce 2 is stuck.

6. Click "identify stuck nonce" to manually trigger the detection and see the stuck nonce value.

7. Enter the stuck nonce to recover (auto-filled if detected) and click "validate recovery" to check if the nonce can be recovered.

8. Review the current nonce, stuck nonce, and transaction history before executing.

9. Click "recover nonce" to sign and submit the transaction that skips the stuck nonce and advances the nonce counter.

10. Click "clear stuck transaction" to permanently remove the stuck transaction from the pending queue.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with any EVM-compatible multisig contract that implements a standard interface (nonce() view, pendingTransactions() view, getSigners() view, getTransactionStatus(uint256) view, recoverNonce(uint256) external, clearStuckTransaction(uint256) external, getTransactionHistory() view). The recoverNonce function advances the nonce counter past the stuck nonce, allowing subsequent transactions to be processed. The clearStuckTransaction function removes the stuck transaction from the pending queue entirely. Both functions are protected by multisig authorization — they require the transaction to be approved by the required number of signers before execution. The tool detects stuck nonces by analyzing the transaction history — a stuck nonce is identified as the first missing nonce in the sequence of executed transactions. Transaction handling follows EIP-1559 gas price calculations using receipt.effectiveGasPrice for accurate cost reporting. Recovery metadata is recorded both in the contract's history and locally for audit purposes.

WHAT IT CANNOT SEE

This tool operates purely on-chain and cannot verify off-chain transaction validity — it does not check whether the stuck transaction was maliciously created or was a legitimate transaction that failed. It cannot detect malicious pending transactions — the tool cannot identify transactions that were submitted with malicious intent, such as drain attempts or unauthorized transfers. It cannot ensure recovery safety — skipping a stuck nonce may skip over legitimate transactions that were waiting to be executed. It cannot validate signer intent — the tool cannot confirm that all signers approve of the recovery action. The tool also cannot guarantee that recovery is authorized — the contract's authorization logic must be correctly implemented, and the tool relies on it for security.

PLEASE NOTE

This tool works exclusively with EVM-compatible blockchain networks (Ethereum, Polygon, Arbitrum, Optimism, Base, etc.). It requires the multisig contract to implement the interface described above. All transactions incur gas fees paid by the connected wallet. The tool maintains no persistent storage — all state is refreshed from the blockchain on each session. Recovering a stuck nonce is a significant action that can affect pending transactions — ensure you understand the implications before executing. Always test on a testnet first and verify that the stuck nonce detection is correct. Consider consulting with other multisig signers before performing a recovery.
