Detailed description
The CoolWallet Pro delivers advanced cold storage security in a sleek, ultra-portable form factor. It secures your private keys offline while letting you manage, send, receive, and interact with supported crypto assets via encrypted Bluetooth and your mobile device.
Built for modern crypto users, the wallet supports a broad range of blockchains and tokens (*), and integrates directly with Web3 services. Native staking for multiple cryptos is available within the CoolWallet ecosystem, and the wallet supports buying, selling, swapping, and interacting with DeFi protocols and NFTs through the mobile application.
The device uses a CC EAL 6+ secure element chip, one of the industry’s highest security certifications, and is validated by independent security analysis to keep your private keys protected at all times.
Security is reinforced through encrypted Bluetooth communication and app-side transaction confirmations, ensuring private keys never leave the hardware. Even if the physical device is lost, assets can be recovered with a securely backed-up seed phrase.
