ZKSAFE is a Chrome extension developed by BUSYAPE LIMITED. It is a security partner for crypto wallets, specifically designed to provide personal multi-signature protection services for Ethereum on-chain assets. This extension allows users to create a smart contract wallet in Ethereum and set an on-chain password.

With ZKSAFE, users can securely store their assets in the Safebox and complete withdrawal operations by inputting the on-chain password through the extension. The interface of the extension provides users with details of the asset transfer, allowing them to perform sensitive operations such as entering a password in a secure environment. Users have the option to approve or deny the transfer within the extension.

It's important to note that ZKSAFE only reads the password entered by the user and immediately erases the information after the asset transfer operation. The extension does not read the user's private key, so it is necessary to install another wallet extension for private key management.
