Description
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.
