Easily manage assets with just one APP

APP only transmits data, does not store the private key, your private key is always offline

The Sallet One App works seamlessly with your cold wallet to easily manage and trade digital assets, but is only used to transfer data. It does not store your wallet credentials or private keys, and the assets remain offline. Even if the App is maliciously hacked, there is no threat to your assets
