CoolWallet, created by the Taiwanese company CoolBitX Technology, is a compact hardware wallet designed to store cryptocurrency. It is represented by two models: CoolWallet S and CoolWallet Pro, both of which have a number of key features.

The main features include:

• Support for more than 10 thousand tokens.

• Extremely thin and lightweight body.

• Waterproof, ensuring safety in extreme conditions.

The wallet is managed through a mobile application for iOS and Android devices, without requiring a computer connection. The interface supports various localizations and automatically adapts to the language settings of the smartphone.

CoolWallet S and CoolWallet Pro differ in the number of blockchains supported and the availability of additional features, offering users a variety of options depending on their needs.

How CoolWallet works

The CoolWallet is a compact device, similar in size to a credit card, with a small monochrome screen. It serves to store private keys and provides access to cryptocurrency in the "cold" storage mode, that is, without a direct Internet connection.

To conduct transactions, CoolWallet is synchronized with a mobile application through which cryptocurrency is transferred from or to the device. This allows you to provide an additional level of security, since private keys remain outside the online environment, minimizing the risks of hacking or cyber attacks.

This approach makes CoolWallet a convenient and secure tool for managing cryptocurrency assets, allowing users to have full control over their funds with minimal risks.

CoolWallet S

The CoolWallet S is a basic hardware wallet model that stands out for its compact size and stylish design. It remains competitive due to its comfortable shape and ergonomic design. Interestingly, the advanced version of CoolWallet Pro does not differ from it in size and form factor, providing users with the same level of comfort when using.

The package when buying CoolWallet S includes:

• The hardware wallet itself is a model S.

• A charger for recharging your wallet.

• User manual for easy setup and use.

• Two cards for recording the LED phrase necessary to restore access to the wallet in case of loss or damage.

This kit provides a complete start to working with the wallet, providing everything you need for safe and convenient storage of cryptocurrency.

Technical specifications and functionality

The basic model of the CoolWallet S hardware wallet has a number of key features that ensure a high level of security and functionality:

• Secure Element CC EAL 5+ chip: 

This chip represents a bank-level security system, ensuring the security of the device and the storage of private keys.

• Secure Bluetooth connection: 

CoolWallet S uses a robust AES-256 encryption algorithm for the Bluetooth connection, making it virtually impossible to crack.

• Autopsy protection: 

Due to the peculiarities of the form factor, the wallet is difficult to disassemble, and when disassembled, it becomes inoperable and cannot be connected to the application.

In addition, the CoolWallet S is equipped with a basic set of features, including:

• Interaction with decentralized platforms.

• Cryptocurrency exchange.

• Purchase of cryptocurrency for fiat via a third-party service.

• Purchase, storage and sending of NFT (non-exchangeable tokens).

• Scanning smart contracts when using dApps to protect against phishing.

• Analysis of the security of cryptocurrencies and NFT upon receipt.

These features make CoolWallet S a full-fledged tool for the secure storage, management and exchange of cryptocurrencies, as well as NFT.

Advantages of CoolWallet S 

CoolWallet S has a number of advantages that make it an attractive choice for users:

• Support for 14 blockchains:

The wallet supports 14 different blockchains, which allows users to store and manage various cryptocurrencies in one convenient place.

• Affordable price: 

The base model of the CoolWallet S offers an affordable price offer, which makes it accessible to a wide range of users.

• High security: 

The banking-level protection system with the Secure Element CC EAL 5+ chip, a secure Bluetooth connection and tamper protection provides a high level of security for storing private keys and cryptocurrency assets.

• Bluetooth Connection:

Bluetooth connection provides convenient connection to mobile devices for wallet management, making the cryptocurrency management process more flexible and mobile.

• Access to dApps and exchangers: 

CoolWallet S provides access to decentralized applications (dApps) and exchangers, allowing users to interact with a wide range of cryptocurrency services and functions directly through their wallet.

These advantages make CoolWallet S an attractive solution for those who are looking for a convenient, secure and multifunctional hardware wallet to manage their cryptocurrency assets.

Disadvantages of CoolWallet S 

Indeed, it is important to note that CoolWallet S does not support the staking function, which allows cryptocurrency owners to earn interest on storing and maintaining network security. This may be a disadvantage for those who are actively involved in mining or staking processes.

It is also worth considering that the CoolWallet S does not connect directly to a personal computer. The wallet is managed through a mobile application that provides secure and convenient interaction with the device. For those who prefer to manage their cryptocurrency assets via a PC, this may be a limitation.

Overall, although the CoolWallet S has many advantages, including compact size, high security and convenient Bluetooth connectivity, the lack of a staking function and the inability to connect to a PC may be limitations for certain users who actively use these features.

CoolWallet Pro

CoolWallet Pro, as an advanced model in the manufacturer's line of devices, offers an improved security system and additional features compared to the basic version of CoolWallet S. Despite this, the form factor and configuration remain the same as that of the S model.

The distinctive features of CoolWallet Pro include:

• Improved security system: 

The Pro version may have an improved CC EAL 6+ security chip, which provides an even higher level of protection for private keys and cryptocurrency assets.

• Additional Features:

In addition, CoolWallet Pro can provide an expanded set of features or improved cryptocurrency management capabilities compared to the base model. These may be new opportunities to interact with various blockchains, improved security options, or other innovations.

• Color scheme: 

The CoolWallet Pro differs from the Model S in the blue color of the case, which may be attractive to users who prefer certain color solutions.

However, despite these differences, the CoolWallet Pro package remains the same as the Model S, including a wallet, instructions, charger and LED phrase storage cards. This allows users to get advanced features and an increased level of security without changing their usual set of accessories.

Technical specifications and functionality

The addition of a CC EAL 6+ certified chip to the CoolWallet Pro hardware wallet represents a significant security improvement over the base model. CC EAL 6+ is one of the highest levels of security certification, which confirms the high standard of protection and reliability of the device.

This chip provides an additional layer of security for storing private keys and other confidential information on the wallet. It can provide more powerful cryptographic functions and more sophisticated protection mechanisms, which makes a hardware wallet even more reliable for storing cryptocurrency.

In addition, the use of reliable data encryption and tamper-proof algorithms, as in the basic model, provides additional layers of protection, making CoolWallet Pro one of the safest ways to store cryptocurrencies on the market.

Advantages of CoolWallet Pro

The advanced CoolWallet Pro model has a number of advantages that make it an attractive choice for users:

• Compact size: 

Like the base model, the CoolWallet Pro remains compact and convenient for daily use due to its small size, which provides mobility and convenience in storage and use.

• More than 30 supported blockchains: 

CoolWallet Pro supports more than 30 different blockchains, which allows users to store and manage a variety of cryptocurrencies and tokens in one wallet.

• Staking is available: 

Unlike the basic model, CoolWallet Pro provides an opportunity to participate in staking, which allows cryptocurrency owners to earn interest on storing and maintaining network security.

• Improved Secure Element CC EAL 6+ chip: 

CoolWallet Pro is equipped with an improved Secure Element CC EAL 6+ chip, which provides an even higher level of security and protection of private keys and cryptocurrency assets.

These advantages make CoolWallet Pro an attractive choice for users who appreciate the combination of compact design, advanced features, high security and the ability to participate in staking.

Disadvantages of CoolWallet Pro

CoolWallet Pro, like the base model, does not have the functionality of direct connection to a personal computer. Wallet management and transactions are carried out through a mobile application that communicates with the device via a secure Bluetooth connection.

Although it may seem to some users that the lack of a direct connection to a PC limits the functionality of the device, this approach actually provides an additional level of security. Since CoolWallet Pro does not require a direct Internet connection or USB connection to a computer, the risk of hacking or cyberattacks is reduced as private keys remain outside the online environment.

Thus, although the lack of a direct connection to a PC may limit some functions or ways of use, this solution provides an additional layer of security, which is one of the key advantages of CoolWallet Pro.

Authentication 

The design of the CoolWallet is designed with high security standards in mind, making it unsuitable for tampering. This provides an additional layer of protection for users, as fake or modified devices will not be able to work or intercept data.

Although there is no formal device authentication procedure, each CoolWallet card has a unique serial number that is displayed in the app after pairing. This provides the user with the opportunity to additionally verify that the device is original.

Purchasing a device through the manufacturer's official website also guarantees its authenticity and reliability. This ensures the user's trust in the device and confidence in its security when used to store cryptocurrency.

Commissions and fees

CoolWallet does not charge additional fees for conducting cryptocurrency transactions. However, as is the case with most cryptocurrency wallets, for each transaction on the blockchain network, the commission is charged by the blockchain itself. This commission is used to pay miners who ensure the operation of the network and confirm transactions.

The amount of the commission depends on several factors, such as network congestion, the type of transaction (for example, a regular transaction or a high-priority transaction) and the specifics of a particular blockchain. These fees are usually small and amount to only a few cents, but may vary depending on circumstances.

Thus, although CoolWallet does not charge additional fees, users should be prepared for the fact that they may be charged a small network fee for each transaction on the blockchain network.

Safety

When connected for the first time, CoolWallet generates a SEED phrase consisting of 12, 16 or 24 words, which ensures data protection. Private keys are securely stored in a certified Secure Element CC EAL chip 5+/6+ (depending on the model), providing a high level of security.

Bluetooth with AES-256 encryption algorithm is used to connect to the wallet. Physical authentication is performed by pressing a button, and when syncing with the application, you need to enter the verification code generated along with the passphrase. This ensures the protection of private information in case of loss of the device.

The manufacturer also uses a patented "cold compression" technology, which makes the wallet inoperable when trying to disassemble. This means that it cannot be opened without loss of functionality, which provides an additional level of security.

The fact that there have been no cases of hacking since the release in 2014 indicates a high level of reliability of CoolWallet.

Reviews 

CoolWallet, produced by a Taiwanese company, is really very popular, as evidenced by numerous reviews. Interestingly, the younger model, the CoolWallet S, attracted more attention due to its affordable price and compact size.

Many users note that it is the dimensions of the device that have become the decisive factor in choosing. This is especially important for those who value mobility and ease of use. Reviews of CoolWallet S are mostly left by novice crypto investors, who consider it an ideal option for beginners due to its intuitive application.

On the other hand, more experienced traders prefer the CoolWallet Pro version, mainly because of the improved CC EAL 6+ chip. This provides a higher level of security, which is important for storing large amounts of cryptocurrency. Owners of both models note that there are no problems with displaying the balance, which is a noticeable advantage compared to other hardware wallets.

The overall rating of the application is also high, which confirms the satisfaction of users with its functionality and ease of use.
