# CoolWallet > Simple, secure, on the go. CoolWallet is a hardware wallet company that makes credit-card-sized cold storage devices for cryptocurrency. Its products let users store private keys offline while managing assets via a companion mobile app. CoolWallet is a hardware wallet company that designs credit-card-sized cold storage devices for storing and managing cryptocurrency private keys offline. Its devices let users send, receive, buy, swap, and stake digital assets while keeping keys isolated from internet-connected devices, targeting everyday crypto holders who want portable security. The company operates as part of a broader blockchain security business that also builds compliance tooling for virtual asset service providers. The wallets address the risk of exposing private keys on phones or computers by combining a secure element chip with encrypted wireless connectivity to a companion mobile app. This pairing lets a physical card-like device sign transactions without ever transmitting keys to the connected phone, giving users a cold storage option that remains portable enough for daily use. The approach positions the product between fully offline hardware wallets and convenience-first software wallets. The flagship CoolWallet Pro is joined by additional models aimed at different user needs, from long-term storage to lighter everyday carry. Companion features include in-app swapping, staking, a Web3 browser, and transaction risk scanning, all managed through a single mobile application. The products are used by individual holders across a range of supported digital assets who want offline key security without giving up mobile accessibility. - Type: Company - Sector: Custody and Wallets - Status: Active - Founded: 2014-11-01 - Profile: https://thegrid.id/profiles/coolwallet ## Products - [CoolWallet Pro](https://thegrid.id/profiles/coolwallet): CoolWallet Pro is a hardware wallet in a credit-card-sized form factor that stores private keys offline using a secure element chip. It pairs with a companion app over Bluetooth, using an e-paper display and physical buttons for on-device transaction verification, and works across a wide range of blockchains and tokens. Users rely on it for cold storage of digital assets while still being able to stake, swap, and interact with decentralized applications through the connected app. (Hardware Wallet, Live) - [CoolWallet S](https://thegrid.id/profiles/coolwallet): CoolWallet S was a hardware wallet in a credit-card-sized form factor that stored private keys offline using a secure element chip and connected to a companion app via Bluetooth for transaction signing. It supported a range of blockchains and tokens, allowing users to manage cryptocurrency holdings in cold storage while accessing swap and staking features through the paired app. The device has been discontinued and is no longer available for purchase, though existing units continue to receive app support and warranty coverage. (Hardware Wallet, Live) - [CoolWallet Go](https://thegrid.id/profiles/coolwallet): CoolWallet Go is a battery-free hardware wallet that uses NFC connectivity and a secure element chip to store private keys offline. It uses a dual-card backup system instead of a written seed phrase, letting users tap the card to a smartphone to sign transactions across a wide range of blockchains and tokens. The device works with a companion app for swapping, staking, and buying crypto, but lacks an onscreen display for independent transaction verification. (Hardware Wallet, Live) - [CoolWallet App](https://thegrid.id/profiles/coolwallet): CoolWallet App is a software wallet that functions independently as a hot wallet and also serves as the management interface for CoolWallet hardware devices. It lets users send, receive, buy, sell, swap, and stake cryptocurrency, and includes a built-in Web3 browser, WalletConnect support, and transaction risk scanning for interacting with decentralized applications across multiple blockchain networks. When paired with a CoolWallet hardware wallet, the app adds offline key storage while retaining the same interface for managing both cold and hot wallets.
