How Ledger secures your assets
Ledger uses a combination of hardware isolation, cryptographic signing, and user-controlled recovery to protect cryptocurrency assets. Your private keys never leave the device — transactions are signed on-device and the signed transaction is sent to your computer or phone for broadcasting.
Practical security guidance
Start with these simple, effective practices: buy from official channels, never share your PIN or recovery phrase, keep backups offline, and update firmware only through Ledger Live. Treat your recovery phrase as the ultimate key — if it’s exposed, anyone can access your funds.
Connecting to the ecosystem
Ledger Live supports installing apps for Bitcoin, Ethereum, and many other blockchains. You can also connect your device to third-party wallets and dapps for advanced DeFi interactions — but always confirm on-device prompts before approving any transaction.
About recovery and seed phrases
The 24-word recovery phrase is BIP39-compatible. Store it offline and consider using a metal backup for long-term durability. Ledger does not store your recovery phrase — responsible custody is in the hands of the user.
Trust & transparency
Ledger publishes firmware and some code for review. Security researchers regularly audit components and vulnerabilities are addressed through coordinated disclosures and firmware updates.
Support & resources
We recommend the following resources for new users: official setup video, step-by-step written guide, firmware update walk-through, and an FAQ covering lost seed recovery and phishing protection. If you face issues, contact support through official channels — never share sensitive information in public forums.
Security checklist
- Buy only from official Ledger store or authorized resellers.
- Verify device authenticity on first boot using Ledger Live.
- Create a strong device PIN and write down the recovery phrase offline.
- Use metal backup for long-term storage of your recovery phrase.
- Confirm every transaction on-device and verify addresses visually.
Ledger provides robust tooling for self-custody — the remainder of the responsibility rests with the user. Learn, practice safe habits, and keep your recovery phrase offline and secure.
