React Hooks for PnP No Modal SDK
Web3Auth provides essential React hooks for Web3Auth No Modal SDK for managing authentication, chain
configuration, and user interactions within your application. These hooks can be directly imported
from the @web3auth/no-modal-react-hooks
package. Here's an example of how to import them:
import { useWeb3Auth } from "@web3auth/no-modal-react-hooks";
For more information on React hooks, refer to the official React documentation.
Available Hooks
useWeb3Auth
: Provides access to the Web3Auth context initialized via theWeb3AuthProvider
component.
Hook Context Interface

Web3AuthProvider
The Web3AuthProvider
component wraps the main component and injects the Web3Auth-related context
into it. It takes the following properties as its context:
- Table
- Interface
Parameter | Description |
---|---|
web3AuthOptions | Configuration options for Web3Auth. |
adapters | An array of adapters for connecting to different blockchain networks. |
plugins | An array of plugins to add additional functionality to Web3Auth. |
export interface Web3AuthProviderProps {
config: Web3AuthContextConfig;
}
export type Web3AuthContextConfig = {
web3AuthOptions: IWeb3AuthCoreOptions;
adapters?: IAdapter<unknown>[];
plugins?: IPlugin[];
};
export interface IWeb3AuthCoreOptions {
clientId: string;
chainConfig?: CustomChainConfig;
enableLogging?: boolean;
storageKey?: "session" | "local";
sessionTime?: number;
web3AuthNetwork?: OPENLOGIN_NETWORK_TYPE;
useCoreKitKey?: boolean;
uiConfig?: WhiteLabelData;
privateKeyProvider?: IBaseProvider<string>;
}
Please check out the PnP No Modal SDK references for interfaces for the inner parameters.
Shared Methods Descriptions
Once you've installed and successfully initialized Web3Auth, you can use it to authenticate your users. Further, you can use the native provider given by Web3Auth to connect the users to the respective blockchain network.
Natively, the instance of Web3Auth
(referred to as web3auth
in our examples) returns the
following functions:
-
init()
- Initializes the Web3Auth instance.await init();
Returns:
init(): Promise<void>;
-
connectTo(walletName, loginParams?)
- Connect to a specific wallet adapter.await connectTo(WALLET_ADAPTERS.OPENLOGIN, {
loginProvider: "google",
});Returns:
connectTo<T>(walletName: WALLET_ADAPTER_TYPE, loginParams?: T): Promise<IProvider | null>;
On successful login, the
connectTo
function returns anIProvider
instance. You can use this provider to connect your user to the blockchain and make transactions. -
provider()
- Returns the native provider that can be used to make different blockchain transactions. Returns:get provider(): IProvider | null;
-
connected()
- Returnstrue
orfalse
depending on whether the web3auth instance is available or not. Returns:get connected(): boolean;
-
getUserInfo()
- Getting the User's Information.const userInfo = await getUserInfo();
-
authenticateUser()
- Getting the idToken from Web3Auth.const idToken = await authenticateUser();
-
addChain()
- Add chain config details to the connected adapter.await addChain(chainConfig);
-
switchChain()
- Switch chain as per chainId already added to chain config.await switchChain({ chainId: "0x1" });
-
getAdapter()
- Get the connected adapter instance.const adapter = await getAdapter(adapterName);
-
configureAdapter()
- Configure the adapter instance.await configureAdapter(adapterConfig);
-
clearCache()
- Clear the cache.await clearCache();
-
addPlugin()
- Add a plugin to Web3Auth.await addPlugin(plugin);
-
logout()
- Logging out the User.await logout();
