Overview
Ledger makes small physical devices that hold the keys to your crypto offline. Think of it as a security key for your coins. Plug the device into your computer or pair it with your phone, and it signs transactions on the device. Ledger is one of the most widely used hardware wallets in the industry, with French roots and devices that hold Cardano (ADA) alongside Bitcoin, Ethereum, and thousands of other coins1.
Ledger separates transaction signing from the wallet interface on your computer or phone. You review the transaction details on the device and approve the signing request there2.
Key Features
- A tamper-resistant chip. The same kind of chip used in passports and bank cards holds your keys, with physical defences against being pulled apart in a lab3.
- Works with the main Cardano wallets. Pair a Ledger with Eternl, Yoroi, Lace, or Typhon. You still use those wallets day-to-day; the Ledger just signs the actual transactions4.
- One device, thousands of coins. A single Ledger can hold ADA, Bitcoin, Ethereum, Solana, XRP, and most other major cryptocurrencies, instead of buying a separate device for each1.
- Ledger Live, the companion app. A free app for your computer or phone that shows your balance, lets you buy, swap, and stake your crypto, and pairs with the device for signing1.
- A screen on the device itself. The device displays transaction details for review before you approve a signing request2.
What to Expect
Setting up a Ledger takes about ten minutes. You unbox the device, plug it in, install Ledger Live, and write down a 24-word recovery phrase on paper as the device generates it. You then install the "Cardano app" onto the device (just a few clicks in Ledger Live), and you're ready to pair it with a Cardano wallet.
For Cardano specifically, the practical setup is to pair your Ledger with a wallet you already use: Eternl, Yoroi, Lace, or Typhon. The wallet shows your ADA balance and runs the everyday interface, while the Ledger signs anything that moves money. Staking ADA works the same way: pick a stake pool inside the Cardano wallet, confirm on the Ledger's screen, and your ADA remains in your wallet on the Cardano blockchain while earning rewards. Every time you send money, you'll see the amount and address on the small Ledger screen and physically press a button to confirm. This provides a separate step for reviewing and approving signing requests.
The trade-off with any wallet where you hold the keys: if you lose the device and the recovery phrase, no one can get your coins back. Not Ledger, not anyone. Keep the recovery phrase written on paper and somewhere safe, offline.
