Thank you for the detailed report, Arun! Here’s a summary of your issue for the support team:

Issue Summary

  • SDK & Version:

    • SDK: @web3auth/react-native-sdk
    • Version: ^8.1.0

  • Platform: React Native (likely iOS/Android, please confirm if both or only one)

  • Login Method: Web3Auth’s built-in OTP flow (email or SMS passwordless)

  • Network: SAPPHIRE_DEVNET

  • Observed Issue:

  • Initialization & Login Code:

    const web3auth = new Web3Auth(WebBrowser, EncryptedStorage, {
  clientId: Config.WEB3AUTH_CLIENT_ID,
  redirectUrl: Config.LOGIN_REDIRECT_URL,
  network: WEB3AUTH_NETWORK.SAPPHIRE_DEVNET,
  loginConfig: {
    google: googleLoginConfig,
    discord: discordLoginConfig,
    apple: appleLoginConfig
  },
  privateKeyProvider
})
await web3auth.init()
await web3auth.login({
  loginProvider: provider,
  redirectUrl: Config.LOGIN_REDIRECT_URL,
  mfaLevel: 'none',
  curve: 'secp256k1',
  extraLoginOptions
})

  • Extra Context:

    • The issue occurs specifically during OTP verification.
    • No mention of custom authentication or external provider (using built-in Web3Auth OTP).

Next Steps / Suggestions

1. Confirm Platform:
Is this issue observed on both iOS and Android, or only one? (This helps narrow down if it’s a platform-specific WebView or redirect issue.)

2. Redirect URL:
Double-check if Config.LOGIN_REDIRECT_URL is correctly registered in your Web3Auth dashboard and matches your app’s scheme.
See Redirect URL setup in docs

3. WebView/Browser:
Since OTP flow opens a browser modal, ensure your app has the correct permissions and can handle deep links/redirects back from the browser.

4. Debugging:

  • If possible, open the browser’s dev tools or check device logs for errors during the white screen.
  • Are there any console errors or network failures visible?

Request for Additional Info

  • Could you please confirm:
    • The value and format of your redirectUrl (e.g., myapp://auth)?
    • If the issue occurs on both iOS and Android?
    • If there are any errors in the browser console or device logs during the white screen?
