# Integrate Embedded Wallets with the Skale Blockchain in iOS/Swift Applications

> Integrate Embedded Wallets with the Skale Blockchain in iOS/Swift Applications | Embedded Wallets

While using the Web3Auth iOS SDK, you get the private key within the user scope after successful authorization. This private key can be used to retrieve the user's address, and interact with [Skale](https://ethereum.org/) to make any blockchain calls. We have highlighted a few here for getting you started quickly on that.
