SecuX V20
SecuX Technology Inc.
The SecuX V20 is the flagship hardware wallet from Taiwan's SecuX, with a large 2.8" colour touchscreen and an aluminium body. It protects private keys with an Infineon Solid Flash secure element certified to CC EAL5+ and keeps them offline, requiring manual on-screen approval of transactions. It connects over USB-C or Bluetooth 5 BLE to desktop and mobile apps: the Bluetooth convenience, however, means the device is NOT air-gapped. It is multi-asset (Bitcoin, Ethereum, ERC-20, XRP, Litecoin and over 5,000 claimed assets). The official list price is USD 99 (~€92). The firmware is not published as open-source: its security model must be taken on trust.
