WalletKit iOS SDK

The best API to create gasless wallets for your users. Build mobile-first web3 apps with unmatched user experience.

Overview

WalletKit provides SDKs and APIs to build mobile-first web3 apps. At its core, WalletKit provides APIs to create and manage embedded, gasless, and recoverable wallets. These APIs are augmented with no-code tools and APIs to build with tokens and NFTs. Together, WalletKit can be used to build full-fledged web3 apps. Everything has been designed to get you up and running quickly. If you are new to blockchain, you don’t have to learn any complex concepts. If you are a seasoned developer, you can focus on your product and ship faster.

At a high-level, we provide APIs and tools to build with wallets, tokens, and NFTs:

• Wallets: Create secure wallets on any network with a simple API call
• Tokens: Create custom tokens or build with existing tokens like USDC
• NFTs: Mint your own NFTs and build novel product experiences

By combining these building blocks, you can create a wide range of web3 experiences.

Requirements

• iOS 14.0+

Installation

Swift Package Manager

1. In Xcode, select “File” → “Swift Packages” → “Add Package Dependency”
2. Enter https://github.com/usewalletkit/walletkit-ios.git

CocoaPods

1. Add pod 'WalletKit' to your Podfile
2. Run pod install to install the pod

Usage

Configuration

In AppDelegate.swift:

import UIKit
import WalletKit

class AppDelegate: NSObject, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        // Configure WalletKit.
        let projectID = "WALLET_KIT_PROJECT_ID"
        WalletKit.configure(
            projectID: projectID,
            environment: .testnet,
            tokenSource: .walletkit
        )

        return true
    }
}

For SwiftUI projects, register app delegate in your App:

import SwiftUI

@main
struct WalletKitDemoApp: App {

    // Register app delegate for WalletKit setup.
    @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate

    var body: some Scene {
        WindowGroup {
            HomeView()
        }
    }
}

APIs

After importing the SDK, use WalletKit.activity/gas/nfts/tokens/transactions/users/wallets.someMethod to access WalletKit APIs.

import WalletKit

// Access WalletKit APIs.

WalletKit.users.usersLoginAnonymously { result in
    switch result {
    case .success(let session):
        // Handle session.
    case .failure(let error):
        // Handle error.
    }
}

WalletKit.wallets.walletsList { result in
    switch result {
    case .success(let list):
        // Handle list.
    case .failure(let error):
        // Handle error.
    }
}
