If money is not an issue, I would suggest ordering 2 of them at the same time. I have explained the reasons here. For example, Binance smart chain, Polkadot, Solana, and more new blockchains are being supported by many of these hardware wallets. Supporting multiple blockchains is one important feature that a hardware wallet should have in Ledger Nano X is the best hardware wallet to use in , however, if you are looking for a Bitcoin-only wallet, then you can use something like Coldcard hardware wallet.

The beauty of the Ledger wallet lies in its State-of-the-art Security which is possible with the help of 2 chips. Ledger Nano X is the perfect union of hardware security and mobility. The Bluetooth feature will let you use this hardware device on the move with your phone or laptop without using a cable. Read my detailed Ledger Nano X review.

The world is going crazy about this hardware wallet because of its ability to hold multi-cryptocurrency at one time. In Ledger Nano X, you can install multiple crypto wallets at the same time. This remains true even if they removed the chip from the board or fully-replaced the firmware in the main microprocessor.

In fact, even with the secure element removed from the system, and all the secrets of the main micro fully-known and all the secrets held in the second Secure Element, DS28C36B , the attacker would still only get 13 tries before the ATECCB bricks itself. Even if there was some critical security bug in the dual secure element that completely exposed the secrets it holds, your bitcoin would still be safe, because we encrypt the contents of the dual secure element with a one-time pad known only to the main micro.

More details are available in this white paper and the complete source code is available. Read more Genuine vs. Caution Lights To resist Evil Maids, and other sneaky people with physical access to your Coldcard, we sign our firmware with a factory key.

Changing that light's status is actually controlled by dedicated circuitry connected directly to a Secure Element, so a rogue bit of software cannot override it. The circuit for the lights is exposed on the top surface of the product, so any physical tampering by those maids will be visible as well.

You first enter and then you will be shown two words on-screen. Those words are unique for all PIN prefixes, and for each Coldcard ever made. The secrets used to enforce that come from inside the secure element, and are unknown to the rest of the world. Your job is to memorize those two words, keep them secret, and every time you use the Coldcard, check them before entering the final part of your PIN. This protects you against a trojan-horse Coldcard that might look like yours but it cannot know those two words.

Physical Security Both secure elements and critical parts of the main micro are covered by epoxy at the factory. Our clear case is part of our security model too, so you can look and see if a "hardware implant" has been inserted inside your device. Because of the in-depth use of the secure elements, there is no "factory reset" for the Coldcard.
