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.

As well as storing your public and private keys, crypto wallets interface with the blockchains of various currencies so that you can check your balance and send and receive funds. The blockchain of any cryptocurrency contains a public record of all the transactions that have been made since it began. Your wallet address keeps a record of all your transactions, and therefore also tracks your crypto balance.

By following the chain all the way to the present day, a wallet can figure out how many coins you have. See it for yourself. Watch real bitcoin transactions happening in real time. The most common type of wallet out there, desktop wallets are downloaded and installed on your computer.

Easy to set up and maintain, most are available for Windows, Linux and Mac, although some may be limited to a particular operating system. Many cryptocurrencies offer a desktop wallet specifically designed for their coin. The biggest disadvantage is that they also rely on you to keep your computer secure and free of malware, so antivirus and anti-malware software, a strong firewall and a common-sense approach to security are required to keep your coins safe.

Most desktop wallets will provide you with a long string of words upon installation. Mobile wallets are fairly similar to desktop wallets, with the obvious difference being that they run as an app on your smartphone. Mobile wallets feature many of the same advantages and disadvantages as desktop wallets, with your private key stored on your device. Smartphone wallets are often e asier to use compared to their desktop counterparts and include the ability to scan other wallet addresses for faster transactions.

They also make it simpler to access your coins on the go and use cryptocurrency as part of everyday life. Choosing an app that allows you to back up your wallet with a or word passphrase is a good idea. Online wallets most often provided by exchanges but sometimes offered by third parties are connected to the Internet and are generally the easiest to set up and use. Most only require an email address and a password to create an account, and web wallets are usually designed to provide a simple and straightforward user experience.

However, being online is unfortunately also their biggest disadvantage. Because some platforms maintain the wallets of thousands of users, they can become hot targets for hackers. Hardware wallets add another layer of security by keeping your private key on a USB stick or specially designed piece of hardware.

They allow the user to plug the USB stick into any computer, log in, transact and unplug — so while transactions are carried out online, your private key is stored offline and protected against the risk of hacking. As a result, hardware wallets are widely considered to offer the most secure storage option. Prices vary depending on the model you choose, but they generally cost upwards of R You also need to keep the device safe, but if you do lose your hardware wallet, the device itself is PIN-protected and there are usually other protective measures in place to help you recover your funds.

Paper wallets take the concept of entirely offline keys used for hardware wallets to the next logical step: simply print out your public and private keys and use that piece of paper as your wallet. As secure as they are, paper wallets are also complex and quite confusing for beginners. To transfer money to a paper wallet, you use a software wallet any of the above mentioned to send money to the public key printed on the sheet of paper. Most often, this is printed as a QR code for easy scanning.

To transfer money from the paper wallet to someone else, you would first need to transfer money to a software wallet by manually entering the private key into the software , and then transfer money from the software wallet to the recipient as usual. With this in mind, the safest solution is moving your coins into a secure wallet that lets you retain control of your private key.

Compare cryptocurrency wallets. These addresses are given in one of three ways:. Please note that the exact process will vary depending on the type and brand of wallet you choose. For example, hardware wallet users will typically need to connect their wallet device, enter a PIN or password and manually verify the transaction on the device itself.

Receiving coins is even easier than sending them. However, wallets vary greatly in the way this is done: some will provide you with a fixed public address, some will give you a new address for every transaction and others will provide a combination of the two. You can log into your wallet whenever required to check your balances. Other than that, the main thing you need to focus on is maintaining a high level of security at all times.

Wallet security is a crucial consideration for any crypto owner, so keep these tips in mind to ensure you keep your funds as safe as possible:. This is often a PIN code that is sent to your smartphone as an SMS, may expire after a set amount of time and is different every time you log in. This means that an attacker needs to know your username and password as well as be in possession of your phone. Some wallets also require the use of a secondary app installed on your smartphone that generates these PIN codes for you, again adding another layer of security.

The key thing to remember is to do your research and compare a range of wallets. If anonymity is important to you, you may want to consider transacting with a privacy-focused coin such as Monero. You should also be aware that sending a cryptocurrency transaction from your wallet usually attracts a small network fee, which varies depending on the currency being sent.

This depends on the cryptocurrencies you own and the wallet you choose. Some wallets only allow you to store one particular cryptocurrency, while multi-currency wallets can support any number of digital currencies. Light clients only synchronise essential information and fetch additional data from the network when required. Most mobile wallets are light clients, while desktop light clients can also be downloaded. Tim Falk is a freelance writer for Finder, writing across a diverse range of topics.
