CoolWallet Pro

The CoolWallet Pro, launched in 2021 by CoolBitX Technology, is a credit-card-sized Bluetooth hardware wallet that doubles as a tap-and-go signing instrument on supported chains. Built around a CC EAL5+ certified secure element, it keeps private keys offline while pairing seamlessly with iOS and Android phones over Bluetooth 5.0 — no cables, no PC software. A USB-C port and NFC tap extend connectivity for desktop pairings and contactless signing or backup.

The Pro refreshes the original CoolWallet S with a larger supported-coin catalogue (12,000+ assets across 12 mainstream chains including BTC, ETH, SOL, BNB, XRP, LTC, KAS, TRX, DOGE, TON and the broader EVM family), in-app staking for major Proof-of-Stake networks, an on-device Web3 browser for dApps, NFT management built into the CoolWallet App, and WalletConnect V2 for cross-chain dApp delegation. The card itself is the size of a standard bank card and roughly 0.8 mm thick, with a single anti-theft push-button for on-device transaction confirmation and a rechargeable Li-ion battery that lasts weeks between charges.

Priced at $149.01 USD direct from the official coolwallet.io shop, the CoolWallet Pro is the mid-premium pick for crypto users who want genuine wallet-card portability and on-the-go signing without sacrificing bank-grade security silicon.

Credit-card form factor

Exactly the size of a bank card (85.6 × 53.98 mm, ~0.8 mm thick), the CoolWallet Pro slides into any wallet alongside your everyday cards — invisible as a cold-storage device.

Three-connection connectivity

Bluetooth 5.0 for mobile pairing, USB-C for desktop connection, and NFC tap for contactless signing or encrypted backup to a second blank CoolWallet card.

On-device button confirmation

A single physical push-button guarantees that no transaction leaves the wallet without your tactile consent — defending against remote malware that only controls your phone.

12,000+ supported coins

Native support for BTC, ETH, SOL, BNB Smart Chain, XRP, LTC, KAS, TRX, DOGE, TON and EVM-compatible tokens, with unlimited ERC-20 / BEP-20 / SPL token accounts inside the CoolWallet App.

In-app staking

Stake supported Proof-of-Stake assets directly inside the official app — Cosmos (ATOM), Polkadot (DOT), Tron (TRX), Cardano (ADA) and more — without exposing keys to a third-party UI.

Built-in Web3 browser

Connect to dApps, swap, lend and borrow without leaving the official app. WalletConnect V2 support extends cross-chain dApp access to the entire WalletConnect ecosystem.

NFT wallet

View, hold and manage your NFTs natively inside the app alongside your fungible coins.

In-app decentralized swap

Built-in DEX integration lets you swap assets without moving them out of cold storage.

Anti-disaster NFC seed backup

Encrypted one-tap ECIES-encrypted backup to a second blank CoolWallet card — plus standard 12/24-word BIP39 recovery shown only on the device screen.

At the core of every CoolWallet Pro sits a Common Criteria EAL5+ certified secure element — the same certification tier trusted by European banks for their high-end chip cards. The secure element generates and stores private keys inside tamper-resistant hardware; keys never leave the chip unencrypted and cannot be extracted even with physical access to the device.

Layered defences

• Anti-theft PIN + extended password — a device-bound PIN unlocks the wallet for use; an optional longer alphanumeric password inside the CoolWallet App adds a second meaningful barrier to unauthorized pairing.
• On-button transaction confirmation — every outgoing transaction requires the user to physically tap-and-hold the card's button, defeating remote malware that merely controls your phone.
• Tamper-resistant form factor — the sealed-credit-card construction makes physical key-extraction attacks impractical without destroying the device.
• Encrypted NFC backup — the one-tap ECIES-encrypted backup to a second blank CoolWallet card uses asymmetric cryptography so the backup can never leave CoolBitX's secure channel.

Battery & recovery

• Rechargeable Li-ion battery — approximately 25 hours of active use or weeks on standby between USB-C charges.
• Standard BIP39 recovery — if the card is ever lost, the 12/24-word recovery phrase it displays restores the wallet on any BIP39-compatible hardware or software wallet. Always keep your seed phrase offline.

2-year warranty

CoolWallet Pro ships with a 2-year manufacturer warranty on the chip — no registration required.

CoolBitX Technology Ltd. is a Taiwanese blockchain-security company headquartered in Taipei, founded in 2014 by FinTech entrepreneur Michael Ou. The Ou family's heritage runs deep in traditional banking-security hardware — Michael also leads Smart Displayer, a card-shaped display technology company — and CoolBitX was spun out to apply that smart-card expertise to self-custody for digital assets.

In 2017 CoolBitX shipped the original CoolWallet, the world's first credit-card-shaped cold-storage wallet for cryptocurrencies, following a record-breaking Kickstarter campaign that put early cold wallets into the hands of thousands of mainstream users. The CoolWallet S followed as the first mass-market Bluetooth hardware wallet with a CC EAL5+ secure element; the CoolWallet Pro (2021) added staking, dApp access, NFTs and a much wider coin catalogue; and the all-NFC, battery-free CoolWallet Go returned to the company's credit-card roots in 2025 with an even higher CC EAL 6+ certification.

CoolBitX was presidentially recognized as one of Taiwan's nine "Next Big" startups, and the company has shipped cold wallets to consumers in 80+ countries. Alongside the consumer CoolWallet product line, CoolBitX licenses Sygna Bridge — a KYC / AML SaaS for Virtual Asset Service Providers — to exchanges and regulators worldwide.
