CoolWallet S is a credit card-sized Bluetooth hardware wallet that secures your cryptocurrency in cold storage and fits inside your actual wallet. It combines the security of a hardware wallet with the convenience of a software wallet, allowing users to transact on-the-go with complete confidence and ease.
- Security
Your private key is stored safely in a CC EAL5+ certified S.E. Chipset, which is equivalent to FIPS complied security level, similar to the US military’s requirements, and the private key never leaves the CoolWallet S. This chip calculates all the necessary algorithms and transmits only the calculated results (non-sensitive data) out to the phone via Bluetooth.
The Bluetooth connection can only be initialized when the wallet is turned on within a proximity of 10 meters. The design of our product uses an AES256 Encryption to communicate between a CoolWallet S and your phone along with a dedicated pairing passcode. Thus, any unauthorized devices are prohibited to communicate with the card for data retrieval.
The CoolWallet S and our app use a sequence of biometric verification steps as well as a visual check and a physical confirmation button push on the device itself to ensure that you are in control of your CoolWallet S and that the transaction is indeed correct and valid.
CoolWallet S uses a patented "Cold Compression" process which makes it impossible for hackers to install intercepting devices that can alter the transaction details. The CoolWallet S is wafer-thin and there is no extra space on its circuit board. With an adhesive layer that cannot be removed without visual damage, any alteration or tampering will be immediately visible on the CoolWallet.
- Convenience
CoolWallet S supports most major cryptocurrencies (BTC, ETH, LTX, XRP, ZEN, BCH, etc) and all ERC20 tokens. Crypto to crypto and fiat to crypto exchange all available in-app. BitPay is also fully integrated within CoolWallet S.
CoolWallet S also provides step-by-step instructions, user-friendly wallet setup. It’s
water-resistant, impact-resistant, and bendable up to 15 degrees.
- Portability
CoolWallet S is the same size as a credit card and will fit in your actual wallet. It supports both iOS and Android devices via encrypted Bluetooth, so you are no longer required to sit in front of a laptop and to follow a long list of procedures in order to safely access the blockchain with your assets. CoolWallet S is all that you need to have quick and safe access to your coins/tokens.
