Introduction — Owning your keys in a hostile internet
The promise of DeFi and Web3 is compelling: financial tools, marketplaces, and experiences that run without central custodians. But that freedom also comes with responsibility. In the world of self-custody, whoever holds the private keys controls the assets. That means security is not optional — it’s fundamental. For many users, the single most important decision is where and how those keys are stored.
What Ledger provides: hardware + software that separate responsibilities
Ledger combines a physical hardware wallet (the secure element device) and companion software (Ledger Live / Ledger Wallet) so your private keys remain isolated from internet-connected devices. The hardware device signs transactions on a secure chip while the desktop or mobile app handles portfolio views and connectivity. This design prevents remote attackers, malware, or compromised websites from extracting your keys.

Ledger’s dedicated onboarding page (`ledger.com/start`) is designed to guide new users step-by-step: unbox, initialize the device, set a PIN, record the recovery phrase, install network apps (like Ethereum), and safely connect to DeFi or Web3 apps. The page emphasizes best practices so users don’t accidentally expose the 24-word recovery phrase or buy tampered hardware from third-party sellers.
:contentReference[oaicite:1]{index=1}Why the 24-word recovery phrase matters — and how to protect it
A hardware wallet protects private keys stored inside the device, but most devices also generate a recovery phrase — a human-readable backup of those keys. If someone else learns your recovery phrase, they can recreate your wallet on any compatible device and drain funds. Don’t store the phrase in cloud notes, photos, or email. Use a physically secure method (paper, metal backup) and consider geographically separated copies for disaster recovery.
Ledger Live / Ledger Wallet — the trusted companion
Ledger pairs its hardware devices with a user-facing application (recently rebranded and expanded under names like Ledger Wallet) that lets you install blockchain apps on the device, add accounts, view holdings, and approve transactions. Important: the app provides convenience and visibility, but transaction approvals that move value still require confirmation on the hardware device’s screen — that final on-device approval is the security anchor.
:contentReference[oaicite:2]{index=2}Using Ledger with DeFi and Web3 apps — a practical flow
When interacting with a DeFi dApp (e.g., swapping, staking, supplying liquidity), the dApp typically requests a signature from your wallet. With Ledger in the loop, the dApp’s request travels to your computer or phone, then to the Ledger app which prepares the transaction. The transaction details — amounts, destination addresses, and network fees — are shown on the Ledger device. You visually confirm them before pressing the device’s button(s) to sign. This prevents phishing pages from silently approving transfers because the device only signs what it displays.
Assets, networks, and compatibility
Ledger supports thousands of cryptocurrencies and tokens across many blockchains. That breadth means you can secure many DeFi positions and NFTs under the same hardware key, rather than spreading exposure across several custodians. Support includes major chains like Bitcoin and Ethereum, and a growing list of DeFi tokens and EVM-compatible networks.
:contentReference[oaicite:3]{index=3}Common pitfalls and how Ledger.com/start helps avoid them
New users often make avoidable mistakes: buying tampered or second-hand devices, storing recovery phrases digitally, and granting unlimited token approvals to malicious contracts. Ledger’s official onboarding content focuses specifically on these risks: buy only from official channels, keep seed phrases offline, and use limited allowances (approve only the amount you intend to spend). Ledger Start also links to educational material about safely connecting to MetaMask, using contract-specific approvals, and revoking allowances when needed.
Advanced security boosters
For higher security needs, experienced users adopt additional measures: passphrase-protected hidden accounts, air-gapped setups, multisig wallets, and metal backups of recovery phrases. Multisig — where multiple hardware devices or signers are required to move funds — reduces single-point-of-failure risk. Combining Ledger hardware with multisig services or an additional signer can mitigate theft even if one device or backup is compromised.
When Ledger is not the right tool
Hardware wallets are excellent for long-term holdings and active DeFi users who need security when interacting with dApps. They are less convenient for one-time microtransactions or high-frequency bot trading. Custodial services remain sensible for institutions that require regulatory compliance, insurance, or a different operational model. The key is choosing the security model that matches your threat profile and usage pattern.
Final thoughts — trust, transparency, and personal responsibility
Ledger.com/start is more than a setup page; it’s a pathway that helps bring security practices to the people who want to self-custody their assets. By combining hardware isolation, on-device approvals, and clear onboarding guidance, Ledger reduces many of the common vectors attackers exploit. But security in Web3 remains a shared responsibility: device security, cautious UX, and ongoing education are all part of keeping your crypto safe.
