Smart Account Emergency Freeze Tool

WHAT IT DOES

This tool enables smart account owners and authorized administrators to freeze smart accounts during emergency situations. Freezing a smart account immediately restricts all operations, preventing any transactions from being executed — including transfers, approvals, and contract interactions. This is a last-resort security measure used to stop ongoing attacks, prevent unauthorized access, or halt malicious transactions in progress. It connects to your wallet and reads the smart account address, freeze status, frozen assets list, freeze timestamp, unfreeze conditions, freeze history, and timestamps. The tool signs and submits transactions to freeze the smart account, restrict operations, update freeze status, record freeze metadata, and emit freeze 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 smart account deployment.

3. Enter the smart account address and click "load account" to verify the address and detect if a freeze contract is deployed.

4. Click "fetch freeze status" to retrieve the current freeze status, freeze timestamp, frozen assets list, and unfreeze conditions.

5. Review the current status — if the account is already frozen, the tool will display a "FROZEN" badge; if active, it will show "ACTIVE".

6. Click "validate freeze" to verify that the freeze action is available and the account is not already frozen.

7. Click "check freeze history" to view the history of freeze and unfreeze events for the account.

8. Review the account details, current status, and proposed action before executing.

9. Click "freeze account" to sign and submit the transaction that immediately freezes the smart account.

10. Click "unfreeze account" to lift the freeze when the emergency has passed and conditions allow.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with any EVM-compatible freeze contract that implements a standard interface (isFrozen() view, freezeTimestamp() view, getFrozenAssets() view, unfreezeConditions() view, freeze() external, unfreeze() external, getFreezeHistory() view). The freeze function updates the contract state to block all operations — typically by setting a "frozen" flag that all modifiers check before executing any transaction. The unfreeze function reverses this state, returning the account to normal operation. Both functions are protected by authorization controls (e.g., owner-only or multisig approval) to prevent unauthorized freezing. The contract maintains a history of all freeze and unfreeze events, storing timestamps and action types for audit purposes. Transaction handling follows EIP-1559 gas price calculations using receipt.effectiveGasPrice for accurate cost reporting. Freeze metadata is recorded both in the contract's history and locally for the user's reference.

WHAT IT CANNOT SEE

This tool operates purely on-chain and cannot detect off-chain threats — it cannot identify phishing attempts, social engineering attacks, or other off-chain security risks. It cannot validate emergency conditions — the tool does not verify whether the situation actually warrants a freeze, nor does it check that all required approvals are in place. It cannot ensure timely freezing — the freeze is only as fast as the user can connect and submit the transaction. It cannot detect unauthorized access attempts — the tool cannot identify whether someone is attempting to compromise the account. It also cannot guarantee that the freeze prevents all attacks — some attacks may execute faster than the freeze transaction, and the freeze may not cover all attack vectors (e.g., approvals already granted).

PLEASE NOTE

This tool works exclusively with EVM-compatible blockchain networks (Ethereum, Polygon, Arbitrum, Optimism, Base, etc.). It requires the smart account to implement the freeze 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. Freezing a smart account is an extreme measure — only use it in genuine emergencies when you have confirmed an active threat. Always test the freeze and unfreeze mechanism on a testnet first to ensure it works as expected. Remember that freezing does not reverse transactions that have already been executed — it only prevents new ones.
