WalletAuth is a new feature of Fission's Webnative SDK that allows developers to have their users connect to a Webnative-enabled app using a blockchain wallet.
Add WalletAuth to your app, and every one of your users gets a personal encrypted file system that they can access anywhere they have their blockchain wallet keys.
- users can connect to an app using an existing blockchain wallet (for example the popular MetaMask browser extension)
- when users connect to an app, they can access on-chain data as usual but can also access Webnative's encrypted off-chain data storage features.
- under the hood, Webnative creates a Decentralized Identifier (DID) based on the key, formatted as
Your app can request permission to read and write public or private data to a user's file system, giving app developers a decentralized way to store user data – without centralizing it. This is perfect for off-chain data that is either large (e.g. files and images), or especially sensitive (e.g. a user address book). Read more about the WNFS file system »
We will initially be focused on supporting mainnet Ethereum and other EVM-powered chains (e.g. Polygon, EVMOS) with extension wallets or WalletConnect wallets.
