Spawned Web3Auth Setup Guide: Full Integration for Token Launch
This guide provides a complete walkthrough for integrating Web3Auth with the Spawned token launchpad. You'll connect social login authentication to your token project, allowing users to sign in with Google, Twitter, or email while interacting with your Solana token. The setup uses Spawned's built-in tools and the 0.1 SOL launch fee includes access to these integration features.

The Problem
Traditional solutions are complex, time-consuming, and often require technical expertise.
The Solution
Spawned provides an AI-powered platform that makes building fast, simple, and accessible to everyone.
Why Use Web3Auth with Spawned?
Lower the entry barrier for your token's community.
Integrating Web3Auth with Spawned removes a major barrier for mainstream users: complex wallet setups. Instead of requiring a crypto wallet for initial interaction, users can sign in with familiar social logins. This is particularly valuable for gaming tokens or community projects where you want to onboard users who aren't yet deep into Web3. Spawned's structure supports this: the 0.30% fee per trade from creator revenue and the 0.30% ongoing holder rewards can be tracked through these authenticated user sessions. Compared to building auth from scratch, which could cost hundreds in development time, Spawned's integration is streamlined and works with the included AI website builder, saving you $29-99/month on separate site hosting.
Prerequisites Before You Start
Gather these items before beginning the Web3Auth integration. Having them ready will make the setup process smooth.
- A live Spawned project: You must have created a token via Spawned's launchpad (0.1 SOL fee).
- Web3Auth Project ID: Sign up for a free account at web3auth.io and create a new project.
- Social App Credentials: For Google/Twitter login, you need OAuth 2.0 Client IDs from their developer consoles.
- Spawned API Keys: Found in your Spawned project dashboard under 'Developer Settings'.
- Basic understanding of redirect URIs: You'll need to configure where users return after login.

Follow these steps in order to connect Web3Auth to your Spawned token launch.
How Authentication Works with Spawned's Economics
Once integrated, the user flow connects directly to Spawned's token economics. A user arrives at your token's website (built with Spawned's AI builder). They click 'Connect' and choose 'Sign in with Google' instead of 'Phantom Wallet'. Web3Auth handles the login and creates a non-custodial wallet for them in the background. Spawned's system recognizes this user. If they then buy your token via the integrated launchpad, the 0.30% creator fee from that trade is attributed. If they hold the token, they become eligible for the 0.30% holder reward distribution, tracked via their authenticated ID. This creates a clear link between a user's identity and their on-chain activity, which is valuable for community building and analytics. Post-graduation, when your token moves to the Token-2022 standard with 1% perpetual fees, this user mapping persists.
Web3Auth vs. Traditional Wallet-Only Auth
| Aspect | Web3Auth on Spawned | Wallet-Only (e.g., Phantom) |
|---|---|---|
| User Onboarding | Simple social login. No extension install. | Requires wallet install & setup. High friction. |
| Developer Cost | Built into Spawned. No extra fee over 0.1 SOL launch. | Lower initial setup, but higher user drop-off cost. |
| User Data | Email/social profile available (with consent). | Anonymous public key only. |
| Fee Tracking | Can correlate social ID with fee-generating trades. | Tracks by wallet address only. |
| Best For | Gaming tokens, mainstream communities, fan clubs. | DeFi-native audiences, traders. |
The key advantage is reach. For a gaming token launched via How to create a gaming token on Solana, Web3Auth could increase initial user engagement by over 50% by removing the wallet barrier.
Troubleshooting Common Setup Issues
Problem: 'Invalid Redirect URI' error during test.
Solution: The Redirect URI in your Web3Auth dashboard must match exactly what Spawned provides. Copy it from the Spawned integration page, don't type it. Include https:// and check for trailing slashes.
Problem: Social login (Google) opens but fails.
Solution: This is usually due to incorrect OAuth credentials. In Google Cloud Console, ensure the 'Authorized Redirect URI' includes the one from Spawned and https://app.web3auth.io. Also, verify your Google OAuth consent screen is published.
Problem: User logs in but Spawned doesn't recognize them for trading. Solution: Check the network in Web3Auth dashboard. It must be set to 'Solana' and the correct cluster (Mainnet, Devnet). Also, in Spawned dashboard, ensure the integration status is 'Published', not 'Draft'.
Problem: Slow login response times. Solution: Web3Auth offers different tiered infrastructures. The free tier has limits. For high-traffic launches, consider their growth plan. Spawned's 0.30% fee model can help cover this cost at scale.
Ready to Add Social Login to Your Token?
Integrating Web3Auth is a strategic move to broaden your token's audience beyond the existing crypto-native crowd. It works seamlessly with Spawned's entire stack: the launchpad, the fee model, and the AI website builder. Start by creating your token on Spawned with a 0.1 SOL launch fee, then follow this guide to enable social logins in under an hour. If you're building a gaming community, also review our guide on how to launch a gaming token on Solana for broader strategy.

Frequently Asked Questions
No, Spawned does not charge an additional fee for the Web3Auth integration feature. It is included as part of the platform. You pay the standard 0.1 SOL token launch fee. However, Web3Auth itself has a free tier with limited monthly active users (MAU). For very high-traffic projects, you may need to subscribe to a paid Web3Auth plan directly, but the integration setup remains free on Spawned.
Yes. Spawned's integration is designed to offer multiple connection options. When you implement Web3Auth, the standard 'Connect Wallet' button for Phantom, Solflare, etc., remains available. Users can choose their preferred method. This provides a bridge, allowing social login users to later connect a traditional wallet to the same account, merging their social identity with their on-chain wallet activity.
The holder reward system tracks token ownership. When a user authenticates via Web3Auth, Spawned links their internal user ID to the wallet address Web3Auth generates for them. The system scans the blockchain for token holdings in that wallet address. If it holds your token, the user qualifies for the 0.30% reward distribution, which is sent to that linked wallet address. The authentication simply provides a stable identifier behind the wallet.
After graduation to the Token-2022 standard, your token operates independently, but the authentication layer you built remains. The website created by Spawned's AI builder (which hosts the login) continues to function. The connection to Web3Auth persists because it's configured on your domain and Web3Auth's servers. The 1% perpetual fee mechanism operates on-chain and is separate from the front-end auth, so both systems continue working together post-graduation.
Currently, Spawned's deep integration with Web3Auth is optimized for Solana token launches. The setup process and fee mechanics (0.30%/0.30%/1%) are built around the Solana ecosystem. For other chains like Ethereum or Base, while Web3Auth supports them, the automated configuration within Spawned's dashboard is tailored for Solana. For those, more manual configuration of the Web3Auth dashboard would be required. Check our guides for [Ethereum](/use-cases/token/how-to-create-gaming-token-on-ethereum) and [Base](/use-cases/token/how-to-create-gaming-token-on-base) for chain-specific considerations.
Web3Auth uses a non-custodial, threshold cryptography model. The private key is split into shares, with one share held by the user (via their social login) and others distributed across Web3Auth's network. This means no single party, including Web3Auth or Spawned, holds the full key. It's considered secure for holding assets, but as with any software wallet, it's not the same security level as a dedicated hardware wallet. For large holdings, you should still encourage users to transfer to a self-custodied wallet.
Yes, it's fully integrated. When you use Spawned's AI to generate your token's website, the necessary authentication components (login buttons, callback pages) are automatically included in the site structure. You don't need to edit the generated code. The configuration you do in the Spawned dashboard (as per this guide) automatically applies to the live AI-built site, saving you the $29-99/month you might spend on a separate site builder and the development time to integrate auth.
