The Web3 wallet is built into the Binance App. Creating a Binance Web3 wallet requires completing identity authentication, and the multi-party computation (MPC) wallet and Binance account are bound one-to-one. All assets in the wallet are recorded on the chain, so even uninstalling the Binance App will not have any impact on the assets. But be sure to make a wallet backup so that you can restore the wallet after uninstalling the Binance App and gain access to the assets in the wallet.

Q13: Why is the page for entering the password for the backup wallet grayed out?

You can check whether the Google account you are using has Google Drive editing permissions, or check whether iCloud permissions are turned on so that you can connect correctly. In addition, if the Google account you use does not support the Google drive service, you will also encounter situations where backup cannot be performed.

Q14: Is Binance Web3 wallet a self-hosted wallet? Who has control of the assets?

Binance Web3 Wallet is a self-hosted wallet that uses multi-party computation (MPC) technology to split and back up private keys into three shards. You must hold two of the shards to gain control of the wallet. Binance keeps one copy for wallet recovery, and the user holds two copies, so you have control over the wallet.

With Binance Web3 Wallet, you not only have full control over your assets, but you also have the option to export your private keys if you wish to move them elsewhere. Therefore, you are solely responsible for protecting the security of your assets and backing up your wallet. During the wallet recovery process, a copy of the shards held by Binance and the shards backed up by the user will be used, so if the user's backup is lost, we cannot help you recover your wallet.

Q15: What should I pay attention to after activating the "Emergency Export" function?

After activating the "Emergency Export" function, you can export the private key of the Web3 wallet, and Binance will not provide recovery services for the wallet at that time. Please note: this action cannot be undone.

Users can import the exported private key into other wallets and continue to use it, so the assets will not be lost. However, you may be at risk of exposing your private key when looking for other online wallets. If a third party obtains your private key, others will gain control of your wallet. Please pay attention to the security of your assets.
