# Single Sign-On

Verida provides a single sign-on framework based using QR code and deep link to unlock off-chain data (from the Verida Network) and crypto (from multiple blockchains).

It provides a smooth experience to onboard new users to decentralized applications on a range of supported blockchains.

Users who are signed in are provided with a private encrypted collection of databases for the application, secure messaging, and the ability to perform blockchain transactions.

It also uses Deep Links for when you are on the same device as the Wallet.

The Verida Wallet supports the [WalletConnect v2 standards](https://developers.verida.network/docs/single-sign-on-sdk/wallet-connect) to enable developers to use familiar APIs for blockchain interactions.
