# Using WalletConnect for DApps

### Introduction

WalletConnect v2 is a communications protocol for web3 – WalletConnect is a simple yet powerful multichain wallet connection interface that lets you log into DApps on your desktop and sign transactions using Nova Wallet.

{% hint style="warning" %}
Not every DApp will support WalletConnect – the development team for each DApp has to add support for it. Information on how a development team can add WalletConnect functionality is available here: <https://docs.walletconnect.com/2.0/>
{% endhint %}
