Detailed descriptions
The CoolWallet Go is a next-generation cold wallet built for secure and straightforward handling of your cryptocurrency assets. Its ultra-thin card format means you can take it anywhere with ease, while no battery or charging is required – it’s powered via NFC from your smartphone.
Featuring military-grade protection and an EAL6+ certified secure element, CoolWallet Go protects private keys offline, reducing exposure to hacks or theft. The wallet supports more than 35 major blockchains and custom EVM networks, giving users extensive compatibility with all popular assets (*).
The wallet uses the CoolWallet mobile app for transaction signing, portfolio management, Web3 browsing, DeFi interaction, NFT management and more. Backups are easily managed via encrypted NFC transfers (no manual writing of seed phrases required). A standard package includes two cards (main + backup) to ensure safe redundancy.
While designed for everyday security and simplicity, keep in mind that the lack of a built-in screen means transaction details must be verified through the mobile app.
