I. Guide to downloading and installing the Binance app

1. Tap the official download link above to open the download page.

2. During the download, your device may display a security warning. This is because the app is not being downloaded from an official app store, and the warning is part of your device's standard security checks. To complete the download, select “Continue Download” or “Allow.” Rest assured, this does not mean the app itself is unsafe.
