Briefly about the manufacturer of CoolWallet S

It is difficult to talk about the CoolWallet S wallet without having a background from the company that made this product. For this reason, before starting, we introduce the CoolBitX company. The company that created the first mobile hardware wallet .

CoolBitX started working in Taiwan in 2014. The founder and CEO of this company, Michael Oh, after hackers managed to steal Bitcoin from the Mt. Gox, thought of making a hardware wallet for mobile phones.

 

CoolBitX’s goal was to build a reliable, functional and easy-to-use cold wallet. In 2015, this company succeeded in producing and launching its own wallet called CoolWallet. The company is backed by Indiegogo, a crowdfunding platform.

 

After experiencing the launch of its first product and many requests for investment and support, CoolBitX had enough resources to improve and upgrade its product and provide better services. So the company launched CoolWallet S in early 2018. This wallet is now very popular.

What is CoolWallet S?

Now that you have gained some knowledge about the manufacturer of this wallet, we can talk about the wallet itself. CoolWallet S is the world’s first mobile hardware wallet. But what exactly does this mean?

 

First of all, you need to know what a cold wallet is. In general, cryptocurrencies can be stored in two ways: hot and cold. Hot wallets have online interfaces and their software is always connected to the internet. A cold wallet like CoolWallet S is a hardware device that stores your currency on the blockchain by tracking it. Cold wallets do not require an internet connection.

 

So here we review a cold wallet. But what does it mean when it comes to mobile phones? CoolWallet S will be easily accessible on your mobile phone. All you need is an app. Through it you can do all the work related to a wallet.

coolwallet is everywhere

connecting to your mobile phone, both Android and iOS, and provides access to your account wherever you are. Plus, you can connect CoolWallet to your computer via Myetherwallet.

coolwallet is safe

Fast transactions in the coolwallet system; no one is able to open CoolWallet S and only the owner of the wallet, can open the device and manipulate it so the highest security is on CoolWallet S

Technical Specifications

CoolWallet S is the size of a credit card and has an internal metal button. If you make 2 transactions per day, this wallet can hold a charge for up to two weeks. It takes 2 hours to fully charge this device. This device has a 3V 15A rechargeable lithium battery.

CoolWallet S bitcoin wallet uses ECDSA algorithm for digital signature. It is recommended that you restore your wallet in CoolWallet S. This recommendation is because doing this through the wallet has a higher level of security than the wallet’s mobile app.

Specifications and features

CoolWallet S allows you to track and manage your cryptocurrency investments. It also provides you with the fastest way to send and receive cryptocurrencies.

 

oolWallet S is supported by both Android and iOS operating systems, is extremely secure and supports all major cryptocurrencies. In addition, CoolWallet S is waterproof.

What is inside the box of CoolWallet S ?

So let’s check the contents of the box. The CoolWallet S wallet is placed inside a shiny black box, which after opening it, you will encounter a writing from the creator and CEO of this company, that is, Michael Oh.

Inside the box is a recovery word card, a sticker, a charging pad with a USB cable, and of course the CoolWallet S wallet itself.

security

One thing that everyone knows and accepts is the consideration of security when choosing a crypto wallet. As mentioned at the beginning of the CoolWallet S wallet review, the main idea of ​​this wallet was to produce an extremely safe and reliable device for storing cryptocurrencies. What’s the point of having a super cute wallet with great features and design, but no security.

 

First of all, for each transaction, CoolWallet S has three verification steps. Although it may sound boring, it will be a great feature to help secure your assets in the long run.

None of this matters if all your coins are stolen due to some bug or a simple security mistake. Considering these things, let’s check the security of CoolWallet S wallet.

 

The wallet is also protected by a security password that you choose and set. It is a recovery code based system. So you can make as strong a password as you want.

Finally, the wallet will be protected by something known as the Secure Element. A microchip that keeps all your transactions and currencies encrypted.

 

In general, we can safely say that CoolWallet S is a stylish wallet with high security. A cold wallet that currently has one of the best security systems.

Advantages and Disadvantages

With all the information that has been said, the next thing to look at is the pros and cons of this wallet. Of course, a hardware wallet will not be flawless.

 

Advantages:

  • Unique style and functionality: CoolWallet S avoids the common designs that most manufacturers of large hardware wallets follow and has a different design. Instead of conventional designs, this wallet is slim and sleek like a common credit card, using encrypted Bluetooth for connectivity instead of USB or Wi-Fi.

  • Encrypted connection: Encrypted Bluetooth connection is another security option of this wallet. Often times you may not be able to connect to a secure hotspot, especially when traveling.

 

  • Beautiful and stylish packaging: CoolWallet S is one of the few wallets that has compact packaging. Has a sticker and a card to record recovery words. Most importantly, a simple and slim wallet that you can easily fit in your pocket or physical wallet.

  • A user-friendly wallet: Both the hardware wallet and its application have a simple and user-friendly interface. It also has simple and quick setup steps and no problem will arise for this purpose.

  • It has the advantages of a cold wallet: CoolWallet S is always offline. After updating its application, all information will be updated. This method helps in maximizing security.

 

Disadvantages

 

  • Non-open-text wallet: However, there are plans to make this wallet open-text soon.
  • It is not possible to enter the wallet number via QR. Although this feature may be added in the future.
 

As you can see, CoolWallet S has few disadvantages. These disadvantages may be fixed in the future and in new updates.

Trusted by Over 300,000 Customers Worldwide.

The main aim of this wallet is to provide portability and convenience, and to that end, it features a slim and sleek design that makes it easy to take with you wherever you go. Inside the device, you’ll find a secure element (SE) chip for storing your private keys, and there’s also a built-in display for viewing transaction details.

10 Things we love about CoolWallet S

Still not sure you need a CoolWallet S in your life? Let’s see if we can persuade you to make the jump to giving your crypto the premium cold storage they deserve. 

Here are 10 reasons why, according to our users, the CoolWallet is the best Bluetooth hardware wallet for everyday use.

1. On-the-go cold storage, anywhere, anytime

CoolWallet S in Cold

Cryptocurrency exchanges breaking your heart and cheating on you? This week, the 7th major exchange of 2019 got hacked. These hacks and scams won’t stop until digital exchanges are better regulated and improve their security.

Our cold storage wallet keeps your digital assets safe and goes everywhere you go. You retain full control and security  at all times.

2.  The most Secure Element (CCEAL5+)

processor icon

The CoolWallet S  Secure Element adheres to the highest industry standard, namely CCEAL5+(Evaluation Assurance Level Common Criteria).

 

Our Secure Element, which is also used in traditional banking applications, keeps your private key locked up at all times to ensure that no one, not even you, can view it. It only communicates non-essential data over Bluetooth. Unlike other hardware wallets, all transactions are signed within our SE, not your mobile phone or any vulnerable component.

3. Military-grade Bluetooth encryption

icon-bluetooth-connectivity CoolWallet S

It’s nearly 2020. A hardware wallet should connect wirelessly and safely with your phone. The safest option? Bluetooth. We’ve known this since we started in 2014.

 

Over 5 years ago, long before some of our competitors finally realized that Bluetooth is the next big thing for crypto hardware wallets, we started slaving away to make sure our Bluetooth is future-proof and the best in the business.

 

Our users love our stable military-grade AES256 Bluetooth encryption that works seamlessly, securely and reliably with your phone app.

4.  2+1 FA: Biometric and physical verification

The CoolWallet S adds an additional layer to 2FA security to give our users extra peace of mind.

We require a mix of biometric, software and physical verifications to confirm any transaction. 

Biometric Factor Authentication

To use our app, you’ll have to prove you own the phone you’re using, by unlocking both the phone and our app through fingerprint scanning, ID pattern and a PIN code. The choice is yours to decide how many security layers you want to apply. 

Physical confirmation on Card

CoolWalletS-Physical-Confirmation

Any action taken on the app that involves the moving of your crypto assets, requires users to fire up the CoolWallet S and connect to our app. Users must then do a visual check of the transaction details on the card’s little e-paper screen to ensure that your funds are going where you intend it to. Next, you need to physically press the card’s button to authorize the transaction.

 

This is foolproof way to ensure that you’ll immediately notice if a compromised app (not the card- remember it’s tamperproof thanks to its thinness) is trying to trick you. 

5. It’s tamper-proof (and flexible)

The CoolWallet S looks and feels like a credit card. It’s wafer-thin and flat. You can’t open it, unlike USB hardware wallets.

coolwallet s-durability

Most USB hardware wallets are susceptible to supply chain attacks, where third parties open the device and modify it, because they have extra space on their boards.

coolwallet s -quality

The CoolWallet has no space to add any hardware, and moreover, our compression technology ensures that any attempt to tamper with or open our card will result in an unseemly mess that will be immediately visible to the naked eye.

6.  It fits in your actual wallet

Hardware-CoolWallet S-Mobility

Shouldn’t a hardware wallet be as portable as an actual wallet?

The slim ColdWallet fits neatly inside a personal wallet or purse.  It’s discreet and looks like a normal credit card.

 

This means you can take this cold storage wallet everywhere with you and trade, send and receive crypto it on the go, without anyone even noticing.

7.  It’s waterproof and super-durable

Play Video about CoolWallet S

The CoolWallet S is designed for everyday use. It’s built to last, and is bendable (15 degrees) and completely waterproof. You don’t have to worry about it malfunctioning when you hit the beach or it hits your washing machine by accident. Or it drops in your beer! 

Ask yourself this: Would you trust any other cold hardware wallet to still work after you’ve jumped in the pool?

8. App- New Security, Features and Coins Added!

CoolWallet S-APP

We made some big changes in 2019 to make the CoolWallet S more secure, more versatile and of course, compatible with more awesome cryptocurrencies!

 

Trading:

To complement our integrated Changelly feature that allows you to trade your cryptocurrencies on the go, in 2019 we also added an integration with the new Binance DEX, the decentralized version of the world’s biggest crypto exchange, to help our users trade without giving up control to centralized exchanges. 

 

Our WalletConnect feature allows CoolWallet S users to connect to any supporting DEX. 

 

Security:

 In 2019, we added some great new features in 2019 to make the CoolWallet even more secure:  

 

A PIN code for the App

Our users had asked for this one for a while. We listened. Our PIN code feature helps you to keep your portfolio information safe from anyone who has access to your phone. No we didn’t say your Significant Other. You said it!

App-PINcode

Advanced Seed Recovery

This new feature is a high-level feature for our customers who take their security very seriously. It allows you to set up your seed recovery without displaying the details on your phone. It’s a time-consuming process, but very cool. 

CoolWallet-S-Secure-Recovery

9.  A Battery That Lasts 3 Months

icon-charging-dock

The CoolWallet can last 3 months in standby mode on a single charge, which means you don’t have to worry about constantly charging the device.

Our card connects to a little USB docking station that recharges your mobile Bluetooth hardware wallet in no time.

10. The Screen

CoolWallet S-Screen

Aha. The card with the screen. It doesn’t matter how long you’ve been in crypto or how many gadgets you own.

When you press that little button on the CoolWallet S for the first time or the hundredth time, jaws tend to drop. Our display technology is patented and truly unique.

 

Hand it over to your family and friends and watch their faces and ensuing smiles when the “Hello” message pops up.

Conclusion

As mentioned, the world of cryptocurrency hardware wallets is very competitive. For this reason, whenever a new wallet is introduced, this space changes.

One of the most important things to consider when choosing a wallet, apart from the features of the wallet itself, is the manufacturer and its vision. If a company’s only goal is money, this goal will quickly show in the design and security features of its wallet. As you can see in our CoolWallet S wallet review, the company behind it, CoolBitX, has another goal.

 

Also keep in mind that CoolWallet S wallet company is constantly updating its list of supported currencies.

Can CoolWallet Work Stand-alone?

No, CoolWallet ensures security by combining two-factor authentication with a smartphone or a tablet. So it must be used with a smartphone (iPhone or Android) or a tablet (iPad or Android).

Our latest hardware wallet, the CoolWallet was released in 2018 and has been delighting over 150,000 users.
Our company, CoolBitX, was founded in 2014 with a simple purpose –  to create a safer and more convenient way for users to protect their digital assets through the power of blockchain technology.

Why Should I Do A Paper Backup Of My Seeds?

Seed Backups are extremely important in case you lose your CoolWallet !! Do not share your seeds to anyone including CoolWallet officials.

You need it to restore your cryptocurrencies. 

CoolBitX does not keep any record of our clients’ seeds for security measures. 

We will not be able to retest your seeds. If you did not back up the seeds properly or if you lost the seeds, your digital assets would be lost, as we will not be able to recover wallet data for you.

How does cryptocurrencies’s digital signature work?

A Bitcoin digital signature (as an example) and its verification are some of the main key secrets behind the Bitcoin protocol.

It allows non-repudiation as it means the person who sent the message had to have the private key and so, therefore, owns the Bitcoins – anyone on the network can verify the transaction as a result.

The private key creates the public key, which in turn creates the address – and through the mathematics using elliptic curves and modular arithmetic in finite fields the process is achieved.

The sender generates a private key and a public key. They then sign the message with the signature and send their public key, the signature, and the message to the network. The node or receiver then checks using the verification algorithm that the message has been signed by the sender, which can only be done by the holder of the private key to the public key that is sent.

Will My Wallet Be Deleted After A Firmware Update?

No, it will not. While previous versions did require a wallet recovery after every firmware update, all current versions moving on will not. 

*Please note that a wallet recovery will need to be manually performed if you are updating your card’s firmware for the first time. Wallet recovery will automatically be performed after all firmware updates thereafter so you may ignore the warning message.

​Will CoolWallet generate a new address for each transaction?

To ensure the efficiency of the CoolWallet functions, it is designed in a way that does not generate a new address for each transaction. The disadvantage of having massive addresses is that it will ultimately lead to inefficiencies in data retrieval. Moreover, generating only the necessary addresses will allow an easier organization for address management.

Are My Crypto Assets Stored In The Wallet Or The App?

Your digital assets are actually stored in a “wallet address” on the blockchain.
A Blockchain Wallet Address is a collection of corresponding public-private key pairs generated by the ECDSA (Elliptic Curve Digital Signature Algorithm). As the name implies, the “public key” is known to everyone and can be used to encrypt a message, while the holder of the “private key” can decrypt the message. In addition, the “private key itself” can also be used as a “digital signature” so that anyone holding the public key can verify whether the message really comes from the “private key holder (owner)”.
Each cryptocurrency address consists of such a “public key-private key pair”, and holding the “private key” for a particular address means having “ownership” of the wallet address.
Using CoolWallet is a way to protect your private key from being theft.
A “blockchain” is a growing database of transaction information. All transaction messages are confirmed by “Nodes” in the cryptocurrency network, and then the confirmed transaction messages are packaged into “blocks” that follow the previous block. When you execute a transaction, it will be broadcasted to the network. If the transaction is confirmed to have “sufficient balance” and “confirmed to be sent by the private key holder”, it will be included in the next “block”. Therefore, your cryptocurrency is not stored in the card nor in the application.
