Myria Wallet is non-custodial, meaning data isn’t stored on a centralized database. Private keys and other metadata are stored on the user’s device where the wallet is installed. This allows the user to have control over the security of their assets.
Think of the Myria wallet as a different network within your existing Metamask wallet. So using it is similar to switching between Polygon, ETH, BSC, etc. In short, the wallet is the same but the network is different.
