Hardware Wallet Market

It provides Physical Security. Your seed words are stored in a specialized chip, designed to securely store secrets. Only hardware wallet with option to never be connected to a computer, for full operation: from seed generation, to transaction signing. Bright, x64 pixel OLED screen.

Shows all the critical details of your transactions. Lovingly soldered in Toronto, Canada. Secure supply chain verified with: tamper-evident numbered bag, with bag number recorded into device. Real crypto security chip. Your private key is stored in a dedicated security chip, not the main micro's flash. MicroSD card slot for backup and data storage. We provide an optional "duress PIN code".

If you enter that PIN code, instead of the "real" PIN code, nothing special is shown on the screen and everything operates as normal However, the bitcoin key generated is not the main key. It is effectively a completely separate wallet! To take best advantage of this feature, you should put some Bitcoin into the duress wallet. How much you are willing to lose or what you need to make it plausible, we don't know.

The "duress" wallet will still be derived from the original BIP39 words, so you don't need to back it up separately, but there will be no way to get from that wallet back to the original wallet with the real funds in it. But once set , unlike the normal countdown, this special mode covertly bricks the Coldcard. Again, this may form some part of your game-theory for duress situations, but is completely optional. We now support BIP39 passphrases so you can also create an unlimited supply of distraction wallets.

This feature is also useful for your own organization of funds or accounts. Force a time delay when logging into the Coldcard. Then enter your PIN correctly, a second time, to get in. Level up on your USB P. Makes a great gift for the cypherpunk in your life. Interoperation between Bitcoin hardware wallets is now possible, thanks to BIP which introduces a binary file format that all hardware wallets can use. Coldcard has been based on BIP from day one, and uses it exclusively.

We find it quite scary that some Bitcoin wallets trust the main microprocessor with their most valuable secrets. Instead, Coldcard uses a Secure Element to protect your Bitcoin. This little chip is very powerful. Communication is controlled by complex challenges and SHA responses which prevent replay and eavesdropping. The secure element enforces cryptographically, that An attacker cannot brute-force combinations or replay a previous login sequence.

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, the attacker would still only get 13 tries before the secure element bricks itself.

Even if there was some critical security bug in the secure element that completely exposed the secrets it holds, your bitcoin would still be safe, because we encrypt the contents of the 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. 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 the 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, and covered with clear epoxy, so any physical tampering by those maids will be visible as well.

The PIN code on Coldcard is divided into two parts, such as 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.

The secure element 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 element, there is no "factory reset" for the Coldcard. If you forget your Coldcard PIN, there is nothing we can do except remind you to recycle your e-waste responsibly!

When the time comes. Coldcard never needs to touch a computer. This includes everything you need to do in the whole life of the product:. Using our industrial grade MicroSD Cards or any standard MicroSD card, for each of the above steps that require data to come in and out.

Sneakernet for the win! If you don't trust our random number generator, you can generate the BIP39 seed phrase using dice rolls. We help with this process: you just have to press 1—6 for each roll 99 rolls recommended. At the end of that process, you'll have a properly-encoded seed phrase based solely on the dice rolls. We have a convenient backup feature: just a few clicks and an encrypted file is written to MicroSD with everything you would need to restore a lost or broken Coldcard.

Because it's a simple text file inside the encryption , it would also be all you need to switch vendors and avoid any lock-in. Learn more in our on-line docs about Backups. You can even verify our encryption, using any desktop 7z program.

On the Coldcard itself, you can perform quick check that the file is not truncated, and a simple checksum applies. If you don't like the idea of encrypted backups, because passphrases can get lost, we do offer clear-text backup file output. One risk with hardware wallets is malicious software tricking them into displaying incorrect details of a transaction. Coldcard is therefore very careful analyzing the content of the PSBT file and the transaction itself.

These checks include:. Since , BTW. We are the only hardware wallet addressing the problem of substitute devices, and other trojan, by using a secure element. This product is firmware upgradable in the field. Updated firmware must be signed by the factory private key.

It should help that all of the firmware is written in MicroPython. This means you can type python commands directly into the product! You might use this to develop new features, create special transactions, or do special signing requests. As a developer, you can also download the source and compile it yourself to personalize your Coldcard. Opendime is a small USB that allows you to spend bitcoin like a dollar bill. Pass it along multiple times.

Connect to any USB to check balance. Unseal anytime to spend online. Trust no one. Now affordable and using Eink digits! Track the price of bitcoin, see blocks as they are published, and connect Opendimes to display balance, fiat value, and deposit QR.

First and foremost, we use a tamper-evident plastic bag to package the product. Each bag is unique and coded with a number. That "bag number" is written into the Coldcard's secure element as it's put into that bag. That value cannot be changed, and we ask your to verify the bag number when the Coldcard is powered-up for the first time at your location.

The clear plastic case on Coldcard is an important feature as well. There have been demonstrations of inserting custom hardware inside a competitor's hardware wallet to capture key-presses. We cover the secure element, and other sensitive parts of the Coldcard with epoxy.

This makes it harder to remove those chips, or change the wiring around them. Full-sized numeric keypad makes entering PIN easy and quick. Simple packaging, plain design, no fancy boxes, no redundant cables. Pin Games Duress wallet features. Login Countdown Force a time delay when logging into the Coldcard. Need more security?

Using Hardware Wallets on the Solana CLI

At first, the Bitcoin craze left me baffled. I wondered if Bitcoin was another name for digital money, or the other way round. I asked myself, how could it be? I knew it was time to dig out the facts about Bitcoin. I thought Bitcoin would turn out to be another craze that was bound to fizzle out. I was in for a shocker. They intermingled in my online search: Bitcoin wallet, cryptocurrency wallets, hot Bitcoin wallets, cold Bitcoin wallets, passphrases, they all danced around Bitcoin and got my head buzzing and confused.

Clear linking rules are abided to meet reference reputability standards. Only authoritative sources like academic associations or journals are used for research references while creating the content. If there's a disagreement of interest behind a referenced study, the reader must always be informed. The ongoing debate of which is better - hot storage or cold storage - seems like one that will never end. Hot wallets are digital cryptocurrency wallets , while cold wallets are physical devices that store cryptos inside of them.

Hardware Cryptocurrency Wallet and Cold Storage Wallet

Online exchanges and wallet providers can disappear, go offline, be hacked. They are not reliable. It only takes 5 minutes. Your entire wallet is always accessible via your personal 12 to 24 words long recovery seed. When you first set up your Trezor, it will generate the seed for you. When you need to restore access to your wallet, use this offline backup.

The Next Frontier of Crypto Security

In part one , I looked at some of the threats surrounding the use of hot wallets, specifically, clippers and fake login pages. These threats are particularly lethal due to the fact that hot wallets are always connected to the internet. Here, I continue my overview of the cryptocurrency wallet threat landscape by taking a look at malware-laced links as another top danger to hot wallet users, along with some security considerations relevant for cold wallet users. This is called a homoglyph attack. By replacing certain characters in the domain name with ones that either look similar or identical to human eyes but are actually different to computers , phishing operators can craft links that appear to lead to popular websites that actually resolve to malicious sites. ESET telemetry for Q2 showed attackers were focusing on cryptocurrency exchanges with blockchain. Phishing can also happen via another, very typical path — spam emails attempting to clog my inbox. Clicking on malicious links in these spam messages and potentially giving banking trojans, such as Mekotio , a chance to do damage on my PC is quite unwelcome.
