Why do we need a cold wallet to protect our funds?

For those in the currency circle, wallets are certainly no stranger to this matter. I believe that the wallet most people come into contact with is the hot wallet Metamask (also known as the little fox)

But as wallets increase in number, the issue of keeping private keys has become a worry for many people.

Even if they keep private keys, mnemonic phrases, etc., many people forget or have them stolen due to poor management, resulting in the loss of cryptocurrency assets.

Because of this, people's demand for cold wallets has increased sharply, and they want to store crypto assets through cold wallets.

However, there are many different cold wallets on the market, how should we choose?

The difference between cold wallet and hot wallet

Whether it is a cold wallet or a hot wallet, they are both important tools for storing cryptocurrency, but cold wallets are better in terms of storage methods, security, etc.

Cryptocurrencies Appreciate Over Time

When choosing a wallet to store cryptocurrency, most people may not consider the security of the wallet at the first time, but choose a more convenient and convenient wallet.

The usual underlying logic behind this decision stems from the idea that once they need to liquidate their cryptocurrency, they can move it out faster, only to decide on a more robust and secure storage solution if the need arises later.

But cryptocurrencies have been rising in value in recent years, and many investors have ignored the risk of losing potential gains if they were hacked or scammed early on.

Because of the risk of property loss above, hardware wallets represent a more secure measure, not only against immediate losses, but also against future losses that could result in significant profits.

How to choose a cold wallet?

1. Security

Cold wallets are designed to store cryptocurrency ownership securely offline, but each manufacturer uses a different type of technology. Therefore, be sure to look for a wallet with strong encryption, multi-factor authentication, and other security features to keep your mnemonic phrase and private keys safe.

2.Compatibility

Before purchasing a cold wallet, make sure it supports the cryptocurrencies you own. Most cold wallets are designed to support thousands of different cryptocurrencies, however, some only support a limited number of mainstream cryptocurrencies.

3. Cost

Cold wallets come in a variety of price points, from simple and affordable to high-end and expensive. Before purchasing a cold wallet, consider whether the money spent is worth it. If you buy an expensive wallet, make sure that it meets your requirements in the most efficient way.

4.User experience

While the process for each wallet is similar, the look and feel of each wallet can vary greatly, so it's important to find one you like. A wallet with a user-friendly interface that makes it easier for you to navigate and better manage your assets.

About Keystone Wallet

Keystone Wallet is a completely offline hardware wallet that realizes communication interaction through QR codes. Currently, it supports more than 1,000 digital currencies such as BTC, ETH, USDT, BCH, XRP, Tron, LTC, Dash, Polkadot, and Kusama.

Keystone Wallet uses a 4-inch large touch screen, is open source to the product code, and already supports PSBT multi-signature, aiming to provide users with an easy-to-operate cold-end storage solution. The cold end (hardware wallet) and hot end (smartphone) are used together to protect the security of digital assets while simplifying the operation process and optimizing the user experience to a great extent.

Highlights of Keystone Wallet Features

1. QR code transmits data

All hardware wallets are exposed to the Internet to some extent when signing transactions. For a hardware wallet, the degree of detachment is critical, and its degree of detachment depends on how well it reduces the attack surface when transmitting data to and from connected devices.

Compared with USB, NFC, and Bluetooth, the attack surface of QR code is much smaller, and QR code is currently the most suitable hardware wallet data transmission method. Therefore, Keystone Wallet pioneered the solution to transmit large amounts of transaction data through QR codes. At the same time, based on the need to be compatible with desktop wallets such as Electrum and Wasabi, we developed the Micro SD memory card function.

By transmitting data through QR codes, you can verify all information entering and exiting the hardware wallet to ensure that no virus code is passed into the Keystone hardware wallet, and sensitive information such as private keys will not leave the Keystone hardware wallet. Compared to USB, Bluetooth, etc., QR codes are fully verifiable because any ordinary QR code scanner can convert the data contained in the QR code into a readable format.

2.EAL 5+ security chip

Keystone wallet uses a bank-grade security chip, which is used to generate true random numbers, derive public and private keys, sign transactions and other operations. It can protect the private key from being leaked when hackers physically attack the wallet device and ensure private data such as private keys. Never leave Keystone wallet.

Keystone Wallet is the first hardware wallet to open source the security chip firmware code. With open source code, you can verify how all core cryptographic operations, such as private key derivation and signing, are completed within the secure chip. If you want to personally verify the authenticity of the Keystone wallet firmware upgrade package, you can compile the open source security chip firmware code and wallet application layer code provided by our Github. In addition, the hardware circuit design has also been open source and can be viewed.

3. Separate battery design

The weakest point in an electronic device is often the battery, as batteries typically have a short lifespan. The Keystone wallet device uses a removable battery design, which can prevent battery corrosion and extend the battery life. At the same time, both Pro and Keystone Essential support AAA battery power supply, so there is no need to worry about battery failure. Keystone Pro also comes with a 3A battery compartment and rechargeable lithium battery.

Please note that AAA batteries have the problem of unstable voltage and are generally used in remote controls and other products that do not require stable voltage. Therefore, the AAA battery-powered Keystone Essential is mainly suitable for long-term currency hoarding users who do not use it frequently. If you use the Keystone wallet frequently, it is recommended to purchase Keystone Pro.

4. Fingerprint authorization transaction

For experienced hardware wallet users, they may own multiple hardware wallet devices for different purposes. Keystone Pro has added a fingerprint recognition function to avoid password leakage and coin loss caused by peeping, making it convenient for users to use in public scenes such as coffee shops. The fingerprint recognition function can be used to unlock the device, enter the password wallet and sign transactions. Users can also turn off this function at any time in the system settings.

5. Disassembly and self-destruction mechanism

When you carry a hardware wallet with you, it is relatively easy to get stolen or lost. To prevent side-channel attacks when the device is lost, we developed an anti-tamper and self-destruction mechanism when designing Keystone Pro. When the device is subject to a side-channel attack, it will activate anti-tampering and self-destruction, automatically erasing the private key and any sensitive information in the security chip, making it impossible for attackers to extract any sensitive information in the chip.

Keystone wallet already supports BTC, ETH, USDT, BCH, XRP, TRON, LTC, DASH, DOT/KSM, ETH and TRX tokens. You can view our currency support list on the currency support page. In addition, for Bitcoin fans, we provide Bitcoin-only single-currency firmware, where we can minimize code complexity and attack surface.

Summarize

In the field of hardware wallets, security always comes first. In terms of security, I believe there is no absolute security, but Keystone’s security performance is particularly outstanding among cold wallets on the market.

In terms of user experience, the official has also done a good job. It also supports connecting to third-party hot wallets. At the same time, as the official cold wallet partner of Metamask, the powerful mobile wallets and browser wallets of MetaMask and OKX make this hardware wallet easy to use. It's also very convenient.

For users who need a cold wallet, Keystone is suitable from all angles and is also very convenient for users who are using cold wallets for the first time.
