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. Despite Ledger's controversial 2023 Ledger Recover announcement (which revealed that firmware could theoretically expose seed phrases), the Nano X remains one of the world's most widely used hardware wallets.
