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.


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.
