# KeepKey > Take control of your crypto KeepKey is a hardware wallet that keeps private keys offline, with physical confirmation required for every transaction. KeepKey is designed for users who want direct control over their cryptocurrency without third-party access, accounts, or tracking. Users can store, send, and receive digital assets across Bitcoin, Ethereum, Cosmos, Solana, and various other networks via desktop, browser extension, and mobile apps. Every transaction displays on the device screen and requires a physical button press before execution. - Type: Company - Sector: Custody and Wallets - Status: Active - Founded: 2014-01-01 - Profile: https://thegrid.id/profiles/keepkey ## Products - [KeepKey](https://thegrid.id/profiles/keepkey): KeepKey is a physical hardware wallet for private key storage and transaction signing. Keys are generated and stored on the device during setup and never leave it. All transactions are reviewed on the built-in display and require physical button confirmation before signing. Firmware and hardware schematics are fully open source with deterministic, reproducible builds for independent verification. The device supports Bitcoin, Ethereum, Cosmos SDK chains, THORChain, Solana, XRP, TRON, TON, and various EVM networks, with cross-chain swaps via THORChain and Mayachain available through the companion desktop application. (Hardware Wallet, Live, Main Product) - [KeepKey Vault Desktop](https://thegrid.id/profiles/keepkey): KeepKey Vault Desktop is a desktop application for KeepKey hardware wallet management on macOS, Windows, and Linux. It provides multi-chain portfolio tracking across multiple networks, device setup, firmware updates, PIN management, BIP-39 passphrase support, and cross-chain swaps via THORChain and Mayachain. A local REST API on port 1646 enables a companion Browser Extension and third-party applications to communicate with the connected hardware device. The Browser Extension uses the standard window.ethereum interface to connect the hardware wallet to EVM-compatible decentralized applications. A TypeScript SDK (keepkey-vault-sdk) is available on npm for developers building integrations. (Wallet, Live) - [KeepKey Mobile](https://thegrid.id/profiles/keepkey): KeepKey Mobile is a read-only companion application for the KeepKey hardware wallet, available on iOS. It displays portfolio balances across supported chains without storing private keys on the mobile device. Users pair the application with their KeepKey through a QR code workflow to load wallet addresses. Android support is listed as forthcoming.
