In 2026, protecting your cryptocurrencies is no longer a simple technical precaution: it is a vital necessity. Between the resounding bankruptcies of centralized platforms, the resurgence of scams, and the advent of AI capable of generating malware in a few minutes, the ground is undermined. However, there is good news: self-custody solutions have never been so accessible. And Ledgerthe French leader in the sector on a global scale, has succeeded in making them simple, elegant and suitable for everyday life.

1. “Not your keys, not your coins”: take back the power
On a centralized exchange (CEX), you don’t really own your cryptos. It is the exchange that keeps them for you and holds the private keys. And as the collapse of FTX tragically demonstrated, a CEX can go bankrupt, freeze your funds, or worse, use them without your knowledge. With Ledger, it’s over. Your private keys, that long string of characters used to sign transactions to move your tokens, never leave your device. They are generated, stored and used in a secure chip, completely disconnected from the Internet. You become your own bank. And it’s much more reassuring than it seems.
2. A fortress in your pocket: the EAL6+ certified chip
sign them Ledger (Nano S Plus, Nano X, Stax, Flex, Nano Gen5) are equipped with a chip Secure Element certified EAL6+which has the same level of security as biometric passports and military applications. Concretely, even if someone gets their hands on your device, they have no chance of being able to extract your keys. And as proof: to this day, no Ledger signer has been successfully hackeddespite more than 8 million devices sold. And for more security, recent models (Flex, Stax, and Nano Gen5) add a secure touch screen. You see what you sign and, even if your computer is infected with malware, the attacker cannot change the display. You sign exactly what you want to sign.
3. Ledger Wallet: the application that simplifies everything
Contrary to popular belief, having a hardware wallet does not mean making life complicated. It’s even quite the opposite. With the app Ledger Walletfree and available on computer and smartphone, all your operations are centralized. You can :
Aggregate all your addresses and find your tokens: no more need for three Excel spreadsheets to list your tokens, all blockchains combined;
Receive des cryptos : generate an address or receive stablecoins by bank transfer (partnership with Noah).
Buy/sell des tokens : in a few clicks via Revolut, MoonPay, Transak, with bank card, PayPal, Apple Pay…
Send tokens : enter the address and validate on your sign;
Swapper : convert your tokens without leaving the app and at the best rates;
Earn : stake or lend around thirty cryptos with partners like Figment or Kiln.
4. Earn cashback with the payment card
To spend your tokens on a daily basis, Ledger also offers a Mastercard payment card (supplied by Baanx in France). Its advantages are simple and effective:
1% cashback on your purchases, paid back in Bitcoin or USDT;
You spend your cryptos directly without going through an exchange; Management is integrated into Ledger Wallet. You pay for your coffee, your groceries or your Netflix subscription, and a small fraction automatically goes back into your crypto wallet. Savings that happen on their own, without effort.
5. Never lose access: Ledger Recovery Key and Ledger Recover
The fear of losing your recovery phrase (the 24 words) is one of the main anxieties of sign holders. Ledgerwho has thought of everything, offers two solutions:
Ledger Recovery Key (included with touch models): it is a thin card in CB format, equipped with an NFC chip, which stores your seed phrase offline. Protected by a PIN code, it does not fear fire, humidity or prying eyes. A simple tap against your sign and your assets are restored.
Ledger Recover (subscription service): your recovery phrase is encrypted, fragmented and entrusted to trusted third parties. In the event of loss or damage, you regain access by proving your identity. Ideal for investors who prefer a turnkey solution.
6. Ledger is already anticipating the era of AI agents
Autonomous agents (AI capable of carrying out tasks) are arriving in our daily lives. But giving them access to your cryptos also means giving them the possibility of being hacked. A simple command injection hidden in a PDF can turn your agent into an attack vector. Aware of the threat, Ledger took the subject head on. The company offers a Device Management Kit (DMK) which allows an agent to propose an action… which a human physically validates on his signature. MoonPay already uses it for its AI agent wallet. Many improvements are planned in the near future (material identity of agents, rules of governance, proof of humanity, etc.). In short, Ledger ensures that you remain the only real decision-maker.
7. A range for all budgets (and all uses)
Ledger offers five models to suit all profiles, from the most accessible to the most luxurious:
Ledger Nano S Plus (49 €) : the reliable entry-level, EAL6+ chip, connects via USB-C. Perfect for occasional use or as a backup device;
Ledger Nano X (99 €) : portable version with Bluetooth, ideal for managing your cryptos from your smartphone. EAL5+ chip;
Ledger Nano Gen5 (179 €) : our favorite. Anti-reflective, customizable, secure touch screen. The best safety/comfort compromise;
Ledger Stax (399 €) : ultra-thin credit card size, curved screen, wireless charging, magnets to stack them like books. All share the same level of protection: your keys never leave the chip.
In summary
Between military security, the all-in-one application, the cashback card, foolproof backups and a technological edge on AI agents, Ledger ticks all the boxes. And today, whether you have €100 or €100,000 in cryptos, switching to self-custody is no longer an option but a necessity. And with Ledger, nothing could be simpler!
