Cryptocurrency security meets portability in the modern era. While traditional hardware wallets offer excellent protection, they often lack the convenience needed for today’s mobile-first lifestyle. Fortunately, the CoolWallet hardware wallet revolutionizes crypto security with its innovative credit card form factor, making it the most portable cold storage solution available.
In this comprehensive guide, you’ll discover everything about the CoolWallet crypto wallet ecosystem. From understanding its unique card-based design and Bluetooth security to complete setup instructions and troubleshooting common issues, we cover every aspect. Whether you’re a frequent traveler, mobile user, or simply seeking the ultimate in portability, this guide provides all the information you need.
What is a CoolWallet Hardware Wallet?
A CoolWallet hardware wallet is a physical cryptocurrency storage device shaped like a credit card that keeps your private keys completely offline. Developed by CoolBitX, a Taiwan-based company founded in 2014, the CoolWallet crypto wallet pioneered the card-based hardware wallet category, combining security with unprecedented portability.
The Card-Based Design Innovation
Unlike bulky traditional hardware wallets, CoolWallet measures just 0.8mm thin—thinner than three credit cards stacked together. Moreover, this ultra-slim profile allows users to carry their crypto wallet in any standard wallet alongside credit cards and ID. The device features an e-paper display, physical confirmation button, and rechargeable battery, all integrated into a waterproof, durable card.
The CoolWallet Cold Wallet Advantage
A CoolWallet cold wallet operates entirely offline, connecting via Bluetooth only when actively managing transactions. This cold storage approach eliminates the primary attack vectors that compromise hot wallets:
- Offline Key Storage: Private keys never leave the secure card
- Bluetooth Security: Encrypted communication with paired devices only
- No USB Required: Wireless operation eliminates cable vulnerabilities
- Waterproof Design: IP68 certification protects against water damage
- Physical Button: Tactile transaction confirmation prevents unauthorized access
- EAL6+ Security: Military-grade secure element chip
Furthermore, the CoolWallet hardware crypto wallet philosophy centers on making cryptocurrency security truly mobile, enabling users to manage their assets anywhere without compromising protection.

Frequently Asked Questions About CoolWallet Hardware Wallet
Is CoolWallet hardware wallet safe?
Yes, CoolWallet hardware wallets are highly secure. The Pro model uses an EAL6+ certified secure element chip (military-grade), while the S model uses EAL5+ certification. Furthermore, private keys remain offline on the card, protected by PIN code and physical button confirmation. The Bluetooth connection is encrypted end-to-end, and all transactions require both PIN entry and physical button press. CoolWallet has maintained a strong security record since 2016.
How much does CoolWallet cost?
CoolWallet pricing varies by model: CoolWallet S costs $99, while CoolWallet Pro costs $149 from official sources. The Pro includes wireless charging, EAL6+ security, and enhanced features. Both models offer the same credit card form factor and portability. Additionally, limited edition designs may command premium pricing. This one-time investment provides portable cryptocurrency security for years.
Can CoolWallet be hacked?
While no system is 100% unhackable, CoolWallet’s offline key storage makes remote hacking virtually impossible. Private keys never leave the secure chip. Bluetooth communication is encrypted, and physical button confirmation prevents unauthorized transactions even if your phone is compromised. Furthermore, following proper security practices (strong PIN, secure recovery phrase storage) makes hacking practically impossible for average users.
What cryptocurrencies does CoolWallet support?
CoolWallet supports 10,000+ cryptocurrencies across multiple blockchains including Bitcoin, Ethereum (and all ERC-20 tokens), Binance Smart Chain (BEP-20 tokens), Solana (SPL tokens), Polygon, Avalanche, Cardano, Ripple, Litecoin, and many more. Additionally, CoolWallet Pro supports NFTs across Ethereum, Polygon, and BSC. Regular firmware updates continue adding new cryptocurrency support.
What happens if I lose my CoolWallet?
Your cryptocurrency is not lost if you lose your card. Simply purchase a new CoolWallet, select “Recover Wallet” during setup, and enter your 12-word recovery phrase. Consequently, all funds will be restored immediately. Without your PIN, someone finding your card cannot access funds. However, immediate recovery is recommended for peace of mind. This is why securely storing your recovery phrase separately from your card is absolutely critical.
How long does CoolWallet battery last?
CoolWallet battery lasts 2-3 weeks with moderate use on a single charge. Actual battery life depends on usage frequency and Bluetooth connection time. The e-paper display consumes minimal power, contributing to long battery life. Furthermore, CoolWallet Pro charges wirelessly in 1-2 hours, while CoolWallet S charges via USB cable. For optimal battery health, charge monthly even when not actively using.
Is CoolWallet waterproof?
Yes, CoolWallet has IP68 waterproof rating, meaning it can be submersed in water up to 1.5 meters deep for 30 minutes without damage. This protection covers accidental drops in water, rain exposure, or spills. However, avoid intentional submersion and dry the card if it gets wet. The waterproof design makes CoolWallet ideal for travelers and outdoor enthusiasts.
Does CoolWallet work without smartphone?
No, CoolWallet requires a smartphone (iOS or Android) for full functionality. The card operates exclusively through the CoolWallet mobile app—no desktop software exists. This mobile-first design aligns with CoolWallet’s portability focus. Therefore, you need a compatible smartphone to initialize the wallet, view balances, create transactions, and manage accounts.
Is CoolWallet better than Ledger or Trezor?
CoolWallet offers unique advantages: credit card form factor, superior portability, waterproof design, and wireless operation ideal for mobile-first users and travelers. Meanwhile, Ledger and Trezor support more cryptocurrencies and offer traditional form factors with desktop software. CoolWallet is better for mobile users prioritizing portability. Conversely, Ledger/Trezor are better for desktop users wanting maximum coin support. All three provide excellent security.
Can I stake cryptocurrency with CoolWallet?
Yes, CoolWallet Pro supports staking for various proof-of-stake cryptocurrencies directly through the app including Ethereum, Cardano, Cosmos, Polkadot, and others. You earn passive rewards while maintaining complete custody of your assets. The card signs staking transactions using your private keys, maintaining security throughout the process. However, staking availability varies by cryptocurrency and may require minimum amounts.
