How do I connect my wallet to a dApp? (DeFi Access)

Connect to dApps using WalletConnect or our Chrome browser extension. Currently, WalletConnect and Chrome browser extension support connecting to EVM networks in the MPCVault network list and any other EVM networks (For the purposes of this guide, we will refer to them as 'Custom EVM networks') you wish to add. Additionally, the Chrome browser extension supports connections to Aptos, Solana, and Sui.

There are no restrictions on the types of dApps you can connect to, and you can even build your own private dApps and connect your wallet to them.


Steps to connect to dAppโ€‹

  1. Open the dApp you want to connect to. We will use Uniswap as an example. Most dApps have a "Connect" button in the top right corner. Please click that button.

Please note that when the "WalletConnect access" button is closed in the vault settings, WalletConnect isn't supported in this vault.

How to disconnect?โ€‹

After completing the transaction, it is recommended to disconnect to protect your asset security. Disconnecting is very easy. All you have to do is find the WalletConnect field you would like to disconnect from, then click the "Disconnect" button. When prompted, confirm that you would like to disconnect from WalletConnect. That's it!

What to do if you can't connect?โ€‹

If you are unable to connect to our plugin after selecting MetaMask on certain dApp websites, you can try the following solutions:

  1. Check for Updates. Make sure you have the latest version of plugins installed or that your browser is up to date.

  2. Refresh the dApp website.

  3. If you have other active wallet extensions on your browser, you can try closing those wallets before connecting and using our plugin, e.g., Uniswap.
