Smart accounts and Wallet Services configuration

The iOS SDK provides fine-grained control over the showWalletUI and request flows through the walletServicesConfig parameter in Web3AuthOptions. Customize how transaction confirmations display and tailor the wallet UI branding.

note

Wallet Services requires a paid plan. You can use this feature in sapphire_devnet for free. The minimum pricing plan to use this feature in a production environment is the Scale Plan.

WalletServicesConfig

Pass walletServicesConfig in Web3AuthOptions to configure how wallet services behave across your dapp.

Parameters

Parameter	Description
confirmationStrategy?	Controls how transaction confirmations are displayed. Accepts ConfirmationStrategy. Default is .defaultStrategy.
whiteLabel?	Whitelabel configuration for the wallet services UI. When provided, merged with the project-level whitelabel config. Accepts WhiteLabelData as a value.

ConfirmationStrategy

ConfirmationStrategy controls the UI shown when a user needs to confirm a transaction or signature request.

Value	Description
.defaultStrategy	Shows the default Web3Auth confirmation screen inside the wallet WebView. This is the default value.
.modal	Shows the confirmation request in a bottom sheet modal on top of your application, rather than navigating to a new full-screen WebView.
.popup	Shows the confirmation in a small popup window. Useful for minimal UI disruption.

Interface

public struct WalletServicesConfig: Codable {
    public let confirmationStrategy: ConfirmationStrategy?
    public let whiteLabel: WhiteLabelData?

    public init(
        confirmationStrategy: ConfirmationStrategy? = nil,
        whiteLabel: WhiteLabelData? = nil
    )
}

public enum ConfirmationStrategy: String, Codable {
    case defaultStrategy = "default"
    case modal = "modal"
    case popup = "popup"
}

Setup

Configure walletServicesConfig during SDK initialization:

import Web3Auth

web3Auth = try await Web3Auth(
    options: Web3AuthOptions(
        clientId: "YOUR_WEB3AUTH_CLIENT_ID",
        web3AuthNetwork: .SAPPHIRE_MAINNET,
        redirectUrl: "com.yourapp.bundleid://auth",
        walletServicesConfig: WalletServicesConfig(
            confirmationStrategy: .modal,
            whiteLabel: WhiteLabelData(
                appName: "My App",
                theme: ["primary": "#0364FF"]
            )
        )
    )
)

Usage examples

• Show Wallet UI
• Sign Personal Message
• Sign Typed Data

do {
    try await web3Auth.showWalletUI()
} catch {
    print(error.localizedDescription)
    // Handle error
}

do {
    var params = [Any]()
    params.append("Hello, Web3Auth from iOS!")
    params.append(address) // User's EOA address

    let response = try await web3Auth.request(
        method: "personal_sign",
        requestParams: params
    )

    if let response = response, response.success {
        print("Signature: \(response.result!)")
    }
} catch {
    print(error.localizedDescription)
    // Handle error
}

do {
    let typedData = """
    {
        "types": {
            "EIP712Domain": [
                { "name": "name", "type": "string" }
            ],
            "Mail": [
                { "name": "contents", "type": "string" }
            ]
        },
        "primaryType": "Mail",
        "domain": { "name": "Ether Mail" },
        "message": { "contents": "Hello, Bob!" }
    }
    """

    var params = [Any]()
    params.append(address) // User's EOA address
    params.append(typedData)

    let response = try await web3Auth.request(
        method: "eth_signTypedData_v4",
        requestParams: params
    )

    if let response = response, response.success {
        print("Signature: \(response.result!)")
    }
} catch {
    print(error.localizedDescription)
    // Handle error
