How to integrate MetaMask with AirGap Vault

In this guide, we will explore how you can set up MetaMask as a watch-only wallet with AirGap Vault. MetaMask is a non-custodial wallet for accessing EVM-compatible blockchains. Find a Spanish translation of this guide here (provided by Julieta Gallego and Mujeres en Crypto)

If you already have MetaMask installed, you can skip the next step and proceed to bind MetaMask to AirGap Vault. If you prefer to watch a video of how the setup and integration is done, please click here.
