Portal provides MPC wallets and dApp connections for organizations and their users.

To integrate Portal, an organization adds a client library to their mobile app and a few server API endpoints.

​
Installation

We support Cocoa Pods and Swift Package Manager as distribution methods for our swift package.

​
Setup

Add the PortalSwift package through Xcode:
  1. In Xcode, right-click on your project in the Project Navigator
  2. Select “Add Packages…”
  3. In the search field, enter either:
    • Package name: PortalSwift
    • Repository URL: https://github.com/portal-hq/PortalSwift
  4. Select your desired version
  5. Click “Add Package”
You can read more on adding SPM packages here.

​
Initializing Portal

To initialize Portal in your application, create a new instance of the Portal class included in the package dependency you added. You can provide your Client API Key as the apiKey argument during initialization. rpcConfig is a map of CAIP-2 Chain IDs to their respective RPC URLs. We can now create an instance of the Portal class. Below is an example of how you can do this: 
import PortalSwift

let portal = try Portal(
  "CLIENT_API_KEY_OR_CLIENT_SESSION_TOKEN",
   withRpcConfig: [
        "eip155:1": "https://api.portalhq.io/rpc/v1/eip155/1",
        "eip155:10143": "https://api.portalhq.io/rpc/v1/eip155/10143",
        "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp": "https://api.mainnet-beta.solana.com",
        "solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1": "https://api.devnet.solana.com",
    ]
)
Now that we have our Portal instance, the next step is to generate wallets for your user. Let’s create them!
If you are using Client Session Tokens (CSTs), this hint is for you.When your user’s CST expires, all Portal SDKs will throw an error on the next MPC Operation the user makes (e.g. creating a wallet, backing up a wallet, recovering a wallet, or signing). That error will include a code SESSION_EXPIRED in the SDK methods, which you can use as an indicator to refresh your CST.
