Cobo Vault was on June 1st, 2021.
Providing minimal maintenance for the Cobo Vault was solely a top-down decision by Cobo so the original team had left Cobo to create our own company: Keystone.
We unfortunately don’t know how long the Cobo Vault original companion app will receive maintenance. To help users still using the Cobo Vault hardware wallet, we offer this Cobo Vault companion app called "QR Watch-only Wallet" to help keep Cobo Vault functional.
Please kindly note that:
1) We won’t offer any new features to this app since our focus is purely on Keystone.
2) Due to backend limitations, IOST, EOS, ETC, CFX, DCR, FIRO (XZC) and Omni-USDT are not supported by this app. Please use Cobo’s own companion app if you need to send these coins.
3) This App is only for Cobo Vault. It is NOT compatible with Keystone hardware wallet due to different QR code protocol.
1. Download and install QR Watch-only Wallet:
1) Android

2) iOS

2. Firmware version V2.0.0 or newer running on Cobo Vault Essential or Pro.

The firmware version of your Cobo Vault Essential or Pro must be V2.0.0 and newer to properly sync your hardware wallet with the QR Watch-only Wallet. If the firmware version of your Cobo Vault is older than V2.0.0, please upgrade the firmware first.
