Extension wallet refers to a software that runs on a web browser (mainly Google chrome); It includes the basic operations of general wallets, such as transfers, authorization to call contracts, and import/export/create wallet accounts.

The browser extension is a kind of light wallet. Like the APP, it does not need to synchronize the data of the whole node, and does not store the wallet information. All the private keys and passwords of extension wallets are held by the users themselves.

When creating a hidden wallet, a passphrase is an essential tool for encryption and protection. It is typically a string composed of words or phrases used to create the private key or seed phrase of the wallet.

The purpose of a passphrase is to increase the security of the wallet, ensuring that only those who have the correct passphrase can access and control the assets in the wallet. Without the correct passphrase, it is impossible to recover or reconstruct the wallet, so it is very important to keep the passphrase safe.

DApps, are applications developed based on blockchain. They can be run and authorized through the DApp browser. Because of the “openness” of the DApp browser, any developer or individual can open the application they need to use through the DApp browser. Unlike DApps already in the wallet, there is often a high risk of using third-party DApps sent by others or acquired online. Previous cases of asset theft or inability to withdraw funds from participating projects have occurred when using third-party DApps, so it is important to pay attention to the following when using third-party DApps. so it is important to pay attention to the following when using third-party DApps. so it is important to pay attention to the following when using third-party DApps. so it is important to pay attention to the following when using third-party DApps.
