With help of the WalletConnect you can now use BC Vault crypto wallet (from version 1.7.0) with huge amount of DeFi dApps as Uniswap, OpenSea and similar.
Make sure you are using BC Vault Desktop Application v2.0.0 or newer (that supports WalletConnect v2.0).
What is WalletConnect?
WalletConnect is an open protocol to communicate securely between dApps and Wallets. The protocol establishes a remote pairing between two apps and/or devices using a Relay server to relay payloads. These payloads are symmetrically encrypted through a shared key between the two peers. The pairing is initiated by one peer displaying a QR Code or deep link with a standard WalletConnect URI and is established when the counter-party approves this pairing request.

WalletConnect Verify
From the BC Vault Desktop application version 2.0.6, WalletConnect connections will be verified with the help of the WalletConnect Verify API:
All sites that connect to the BC Vault Desktop application through WalletConnect will have one of the following Site statuses:
- Verified - Domain matched: The domain linked to this request has been verified as this application's domain.
Domain you are trying to connect to has been ‘verified’ in WalletConnect domain registry as the registered domain of the application and the domain has not returned as suspicious from either of the security tools WalletConnect works with.
Unverified: The domain sending the request cannot be verified.
This status appears when the domain you are trying to connect to has not been verified in WalletConnect domain registry, but the domain has not returned as suspicious from either of the security tools WalletConnect works with.
WE SUGGEST YOU PROCEED AFTER ADDITIONAL CHECKS OF THE SITE VALIDITY!Warning - Domain mismatch: The application's domain doesn't match the sender of this request.
This status appears when the domain you are trying to connect to has been flagged as a different domain to the one this application has verified in WalletConnect domain registry, but the domain has not returned as suspicious from either of the security tools WalletConnect works with.
WE SUGGEST YOU DO NOT PROCEED WITH THE CONNECTION IF YOU ARE NOT ABSOLUTELY SURE!Warning - Known malicious: This domain is flagged as malicious and potentially harmful.
This status appears when the domain you are trying to connect to has been flagged as malicious on one or more of the security tools WalletConnect works with.
WE SUGGEST YOU ABSOLUTELY DO NOT PROCEED WITH THE CONNECTION!

!!! Be sure to understand what Approval/Revocation means in terms of dApps, your funds can be stolen if you are not careful! See the above Uniswap article for explanation: Uniswap Protocol - Swap, earn, and build on Uniswap with the BC Vault !!!
