What is Keystone?

Keystone (formerly Cobo Vault) is a line of air-gapped hardware wallets that sign transactions over QR codes instead of USB or Bluetooth. Users generate seeds inside multiple secure elements, pair the device with software wallets like MetaMask and Phantom, and approve transfers, swaps, and dApp interactions across Bitcoin, Ethereum, Solana, BNB Chain, TRON, and other supported networks.
