1 — Prerequisites: what you need before you start
Before adding accounts, prepare the essentials: a Ledger hardware device (e.g., Ledger Nano series), a fresh copy of Ledger Live for your platform (desktop or mobile), and a secure, offline place to store your 24-word recovery phrase. Confirm you are downloading Ledger Live from the official source and that your device firmware is up to date. For advanced users, make a plan for passphrases or multisig if you intend to use them.
Hardware security matters: buy devices only from authorized channels to avoid tampering. Have a USB cable (or Bluetooth for supported devices), your device PIN, and a quiet place to perform setup. If you're restoring an existing wallet, make sure you have the correct 24-word recovery phrase and seed type ready (BIP-39 24-word seeds are standard).
