Initializing PnP Web Modal SDK

After Installation, the next step to use Web3Auth is to Initialize the SDK. However, the Initialization is a two-step process, with an additional two steps for customizations, i.e.

• Instantiation of Web3Auth
• Configuration of Adapters (optional)
• Configuration of Plugins (optional)
• Initialization of Modal

Please note that these are the most critical steps where you need to pass on different parameters according to the preference of your project. Additionally, If you wish to customize your Web3Auth Instance, Whitelabeling, Multi Factor Authentication and Custom Authentication have to be configured within this step.

Instantiating Web3Auth

Import the Web3Auth class from @web3auth/modal

import { Web3Auth } from "@web3auth/modal";

Assign the Web3Auth class to a variable

const web3auth = new Web3Auth(Web3AuthOptions);

This Web3Auth constructor takes an object with Web3AuthOptions as input.

Adding a Private Key Provider

privateKeyProvider

privateKeyProvider parameter helps you to connect with various wallet SDKs. These are preconfigured RPC clients for different blockchains used to interact with the respective blockchain networks.

note

It's mandatory to provide privateKeyProvider for your corresponding chain namespace. To know more in-depth about providers, have a look at the Providers reference.

You can choose between the following providers based on your usecase.

• EIP1193 Private Key Provider for EVM Compatible Chains
• Solana Private Key Provider for Solana Blockchain
• XRPL Private Key Provider for XRPL Blockchain
• Common Private Key Provider for Connecting to any Blockchain

EIP1193 Provider

import { EthereumPrivateKeyProvider } from "@web3auth/ethereum-provider";

const privateKeyProvider = new EthereumPrivateKeyProvider({
  config: { chainConfig },
});

const web3auth = new Web3AuthModal({
  clientId: "", // Get your Client ID from the Web3Auth Dashboard
  web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
  privateKeyProvider,
});

Solana Provider

import { SolanaPrivateKeyProvider } from "@web3auth/solana-provider";

const privateKeyProvider = new SolanaPrivateKeyProvider({
  config: { chainConfig },
});

const web3auth = new Web3AuthModal({
  clientId: "", // Get your Client ID from the Web3Auth Dashboard
  web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
  privateKeyProvider,
});

XRPL Provider

import { XrplPrivateKeyProvider } from "@web3auth/xrpl-provider";

const privateKeyProvider = new XrplPrivateKeyProvider({
  config: { chainConfig },
});

const web3auth = new Web3AuthModal({
  clientId: "", // Get your Client ID from the Web3Auth Dashboard
  web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
  privateKeyProvider,
});

Common Provider

import { CommonPrivateKeyProvider } from "@web3auth/base-provider";

const privateKeyProvider = new CommonPrivateKeyProvider({
  config: { chainConfig },
});

const web3auth = new Web3AuthModal({
  clientId: "", // Get your Client ID from the Web3Auth Dashboard
  web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
  privateKeyProvider,
});

Whitelabeling

Within the uiConfig parameter, you can configure the Web3Auth Modal according to your application's requirements.

tip

This is just one of the aspects of whitelabeling you can achieve with Web3Auth. To know more in-depth about how you can Whitelabel your application with Web3Auth Plug and Play Modal SDK, have a look at our Whitelabeling SDK Reference.

Configuring Adapters

An adapter is a pluggable package that implements an IAdapter interface for a wallet within Web3Auth. An adapter can be plugged in and out of web3auth modal. Each adapter exposes the provider on successful user login that can be used to invoke RPC calls on the wallet and on the connected blockchain. Web3Auth's modal UI supports a set of default adapters depending on the authMode being used.

info

This step is generally optional. You don't have to configure any default adapter unless you want to override default configs for the adapter.

Only those adapters that are marked are nondefault in this table on the Adapters Documentation are required to be configured always based on the authMode you are using.

Configuring Openlogin Adapter [Social Logins]

The default adapter of Web3Auth is the openlogin-adapter. This adapter is a wrapper around the openlogin library from Web3Auth and enables the social login features. For customising features of the main Web3Auth flow, like Whitelabel, Custom Authentication, etc. you need to customise the Openlogin Adapter.

tip

Checkout the openlogin-adapter SDK Reference for more details on different configurations you can pass for customisations.

Whitelabeling

whiteLabel

For customising the redirect screens while logging in and constructing the key, you need to pass on whiteLabel configurations to the adapterSettings property of the openlogin-adapter.

tip

This is just one of the aspects of whitelabeling you can achieve with Web3Auth. To know more in depth about how you can Whitelabel your application with Web3Auth, have a look at our Whitelabeling SDK Reference.

import { OpenloginAdapter } from "@web3auth/openlogin-adapter";

const openloginAdapter = new OpenloginAdapter({
  adapterSettings: {
    clientId, //Optional - Provide only if you haven't provided it in the Web3Auth Instantiation Code
    network: "sapphire_mainnet", // Optional - Provide only if you haven't provided it in the Web3Auth Instantiation Code
    uxMode: "popup",
    whiteLabel: {
      appName: "W3A Heroes",
      appUrl: "https://web3auth.io",
      logoLight: "https://web3auth.io/images/web3auth-logo.svg",
      logoDark: "https://web3auth.io/images/web3auth-logo---Dark.svg",
      defaultLanguage: "en", // en, de, ja, ko, zh, es, fr, pt, nl, tr
      mode: "dark", // whether to enable dark mode. defaultValue: auto
      theme: {
        primary: "#00D1B2",
      },
      useLogoLoader: true,
    },
  },
  privateKeyProvider,
});
web3auth.configureAdapter(openloginAdapter);

Multi Factor Authentication

mfaLevel

For a dApp, we provide various options to set up Multi-Factor Authentication. You can customize the MFA screen by setting the mfaLevel argument. You can enable or disable a backup factor and change their order. Currently, there are four values for mfaLevel:

• default: presents the MFA screen every third login
• optional: presents the MFA screen on every login, but you can skip it
• mandatory: make it mandatory to set up MFA after login
• none: skips the MFA setup screen

import { OpenloginAdapter } from "@web3auth/openlogin-adapter";

const openloginAdapter = new OpenloginAdapter({
  loginSettings: {
    mfaLevel: "mandatory", // default, optional, mandatory, none
  },
});

Note

If you are using default verifiers, your users may have set up MFA on other dApps that also use default Web3Auth verifiers. In this case, the MFA screen will continue to appear if the user has enabled MFA on other dApps. This is because MFA cannot be turned off once it is enabled.

mfaSettings

For customising the MFA settings, you need to pass on mfaSettings configurations to the adapterSettings property of the OpenloginAdapter.

tip

Read more about mfaSettings in the Multi Factor Authentication Section SDK Reference.

import { OpenloginAdapter } from "@web3auth/openlogin-adapter";

const openloginAdapter = new OpenloginAdapter({
  adapterSettings: {
    // SCALE and above plan only feature
    mfaSettings: {
      deviceShareFactor: {
        enable: true,
        priority: 1,
        mandatory: true, // at least two factors are mandatory
      },
      backUpShareFactor: {
        enable: true,
        priority: 2,
        mandatory: true, // at least two factors are mandatory
      },
      socialBackupFactor: {
        enable: true,
        priority: 3,
        mandatory: false,
      },
      passwordFactor: {
        enable: true,
        priority: 4,
        mandatory: false,
      },
    },
  },
});

Custom Authentication

loginConfig

With Web3Auth, you have the option to configure logins using your own authentication services. For adding your own authentication, you have to first configure your verifiers in the Web3Auth Dashboard.

Custom Authentication in Web3Auth is supported by the Openlogin Adapter, which is the default adapter for the Web3Auth SDK. For this, you need to configure the loginConfig parameter in the adapterSettings of the openlogin-adapter package.

tip

Refer to the Custom Authentication Documentation for more information.

Usage

Since we're using the @web3auth/modal, ie. the Plug and Play Modal SDK, the loginConfig should correspond to the socials mentioned in the modal. Here, we're customizing Google and Facebook to be custom verified, rest of all other socials will be the default. You can customize other social logins or remove them using the whitelabeling option.

Google

import OpenloginAdapter from "@web3auth/openlogin-adapter";

const openloginAdapter = new OpenloginAdapter({
  adapterSettings: {
    loginConfig: {
      // Google login
      google: {
        verifier: "YOUR_GOOGLE_VERIFIER_NAME", // Please create a verifier on the developer dashboard and pass the name here
        typeOfLogin: "google", // Pass on the login provider of the verifier you've created
        clientId: "GOOGLE_CLIENT_ID.apps.googleusercontent.com", // Pass on the clientId of the login provider here - Please note this differs from the Web3Auth ClientID. This is the JWT Client ID
      },

Configuring External Wallet Adapters

configureAdapter(ADAPTER)

To configure an adapter, create the instance of the adapter by using its corresponding package and pass the returned adapter instance in the configureAdapter function.

tip

Refer to the Adapters documentation to know more deeply about what adapters are available and how to configure them.

Default EVM Adapters

If you want to support All EVM External Wallets, your should use the Default External Adapter for EVM. This adapter supports MIPD (EIP6163) so all available wallets in the browser will automatically be detected as well.

• Import the getDefaultExternalAdapters from @web3auth/default-evm-adapter package
• Get all the adapters in the adapters variable as an array of IAdapter.
• Iterate over the adapters array and configure each adapter using configureAdapter function.

import { getDefaultExternalAdapters } from "@web3auth/default-evm-adapter";

const adapters = await getDefaultExternalAdapters({
  options: {
    clientId,
    web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
    privateKeyProvider,
  },
});

adapters.forEach((adapter) => {
  web3auth.configureAdapter(adapter);
});

Default Solana Adapters

If you want to support All Solana External Wallets, your should use the Default External Adapter for Solana.

• Import the getDefaultExternalAdapters from @web3auth/default-solana-adapter package
• Get all the adapters in the adapters variable as an array of IAdapter.
• Iterate over the adapters array and configure each adapter using configureAdapter function.

import { getDefaultExternalAdapters } from "@web3auth/default-solana-adapter";

const adapters = await getDefaultExternalAdapters({
  options: {
    clientId,
    web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
    privateKeyProvider,
  },
});

adapters.forEach((adapter) => {
  web3auth.configureAdapter(adapter);
});

Configuring Plugins

info

This step is totally optional. If you don't want to use any plugins, feel free to skip this section.

Plugins are essentially extensions to the core functionality of Web3Auth, allowing you to add additional features to your dApp. These features can be used to extend the UI functionalities, making your integration more interoperable, and a lot more, even having the functionality to be customised extremely and to your liking.

tip

Refer to the Wallet Services Plugin Documentation to know more deeply about how you utilise our plugins to extend the functionality of your dApp.

import { WalletServicesPlugin } from "@web3auth/wallet-services-plugin";

const walletServicesPlugin = new WalletServicesPlugin();

web3auth.addPlugin(walletServicesPlugin); // Add the plugin to web3auth

Initializing Modal

initModal()

The final step in the whole initialization process is the initialize the Modal from Web3Auth.

This is done by calling the initModal function of the web3auth instance we created above.

await web3auth.initModal(params);

Arguments

The web3auth.initModal takes an optional params config object as input.

params?: {
  modalConfig?: Record<WALLET_ADAPTER_TYPE, ModalConfig>;
}

This params object further takes a modalConfig object using which you can configure the visibility of each adapter within the modal. Each modal config has the following configurations:

modalConfig

Table

modalConfig: { ADAPTER : { params } }

Parameter	Description
label	Label of the adapter you want to configure. It's a mandatory field which accepts string.
showOnModal?	Whether to show an adapter in modal or not. Default value is true.
showOnDesktop?	Whether to show an adapter in desktop or not. Default value is true.
showOnMobile?	Whether to show an adapter in mobile or not. Default value is true.

Additionally, to configure the Openlogin Adapter's each login method, we have the loginMethods? parameter.

Parameter	Description
loginMethods?	To configure visibility of each social login method for the openlogin adapter. It accepts LoginMethodConfig as a value.

Interface

initModal(params?: {
    modalConfig?: Record<WALLET_ADAPTER_TYPE, ModalConfig>;
}): Promise<void>;

interface ModalConfig extends BaseAdapterConfig {
    loginMethods?: LoginMethodConfig;
}

interface BaseAdapterConfig {
    label: string;
    showOnModal?: boolean;
    showOnMobile?: boolean;
    showOnDesktop?: boolean;
}

loginMethods: { label: { params } }

In loginMethods, you can configure the visibility of each social login method for the openlogin adapter. The social login is corresponded by the label parameter. Below is the table indicating the different params available for customization.

For labels you can choose between these options: google, facebook, twitter, reddit, discord, twitch, apple, line, github, kakao, linkedin, weibo, wechat, email_passwordless

Usage

With Modal Configurations

await web3auth.initModal({
  modalConfig: {
    [WALLET_ADAPTERS.OPENLOGIN]: {
      label: "openlogin",
      loginMethods: {
        google: {
          name: "google login",
          logoDark: "url to your custom logo which will shown in dark mode",
        },
        facebook: {
          // it will hide the facebook option from the Web3Auth modal.
          name: "facebook login",
          showOnModal: false,
        },
      },
      // setting it to false will hide all social login methods from modal.
      showOnModal: true,
    },
  },
});

Without Modal Configurations

await web3auth.initModal();
