Ledger Nano X

Ledger Nano X is Ledger's flagship Bluetooth-enabled hardware wallet, released in 2019. It supports over 5,500 cryptocurrencies including Bitcoin and offers wireless connectivity for use with the Ledger Live mobile app on iOS and Android. The Nano X features a larger screen than its predecessors, a built-in battery for mobile use, and can store up to 100 apps simultaneously.
