Ledger is one of the most popular and secure cryptocurrency wallets in the world and Decimal (DEL) applications have the ability to manage their assets not only through the regular console (console.decimalchain.com), but also in the Ledger Live application.
Due to the physical device, Ledger provides you with an additional layer of protection for your transactions. Even if someone gets access to devices with Ledger Live, they will not be able to complete the transaction without a physical device and a special pin code on it.
