Spawned Metamask Integration Guide: Launch Solana Tokens for Ethereum Users
This guide details how to integrate Spawned, a Solana-based token launchpad, with Metamask to serve Ethereum users. We cover the technical setup, fee implications, and the unique revenue model that benefits both creators and token holders. Using Spawned's AI website builder saves on monthly costs while providing a full launch ecosystem.

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.
Should You Integrate Spawned with Metamask?
A clear recommendation for developers targeting a multi-chain audience.
If your target audience includes Ethereum users who primarily use Metamask, integrating Spawned is a logical step. This setup allows you to tap into the Ethereum user base while launching on Solana for lower fees and higher speed. The 0.30% creator revenue per trade provides an immediate income stream, a feature not available on platforms like pump.fun. The included AI website builder eliminates a recurring $29-99 monthly expense, making the total launch cost effectively just 0.1 SOL. For projects aiming for cross-chain presence from day one, this integration is recommended.
Why Bridge Solana and Ethereum for Your Token Launch?
The strategic advantage of connecting two major blockchain ecosystems.
Ethereum boasts the largest DeFi user base, with millions of active Metamask wallets. Solana offers transaction costs under $0.01 and block times around 400 milliseconds. By launching your token on Spawned (Solana) and integrating Metamask (Ethereum), you combine Ethereum's liquidity and user familiarity with Solana's performance. For example, a gaming token can use Solana for fast in-game transactions while allowing Ethereum users to hold and trade the asset in their preferred wallet. Spawned's model ensures you earn 0.30% on every cross-chain trade that occurs post-launch, creating a sustainable revenue model from both ecosystems.
Step-by-Step: Connect Spawned to Metamask
A practical, step-by-step walkthrough for developers.
Follow these steps to enable Metamask users to interact with your Spawned-launched Solana token.
- Launch Your Token on Spawned: Complete your token creation on the Spawned platform. The 0.1 SOL fee covers deployment and the AI-generated website. Learn about launching gaming tokens on Solana.
- Choose a Cross-Chain Bridge: Select a bridge like Wormhole or Portal Bridge. These protocols lock your Solana-native token on the source chain and mint a wrapped representation (e.g., a Wormhole-wrapped token) on Ethereum.
- Add Ethereum Contract Address: Once the wrapped token is created on Ethereum, note its contract address. You will need this for listings and liquidity provisioning.
- Provide Liquidity on Ethereum DEXs: Add liquidity for your wrapped token on a decentralized exchange like Uniswap (Ethereum) or a Base DEX if extending to that chain. This allows Metamask users to swap for it.
- Configure Your Spawned Website: Use the included AI builder to add clear instructions for Metamask users, including the Ethereum contract address and links to the bridge interface for asset transfers.
Fee Structure: Spawned vs. Ethereum-Only Launches
A detailed cost-benefit analysis of the integrated approach.
Understanding the cost and revenue implications is critical.
| Fee Type | Spawned (Solana) + Metamask (Ethereum) | Standard Ethereum Launch (e.g., Uniswap) |
|---|---|---|
| Launch Cost | 0.1 SOL (~$20) + Ethereum gas for bridge/deploy | $50 - $500+ in Ethereum gas fees alone |
| Website Cost | $0 (AI builder included) | $29 - $99/month for similar service |
| Creator Revenue | 0.30% on every trade (Solana & cross-chain) | Typically 0% on standard DEX pools |
| Holder Rewards | 0.30% ongoing rewards distributed to holders | Rare, usually requires custom staking contracts |
| Post-Graduation Fee | 1% perpetual via Token-2022 | Not applicable |
The key difference is ongoing value flow. While an Ethereum-only launch might have higher upfront gas costs, it generates no automatic revenue for the creator. Spawned's model builds a 0.30% revenue share and holder rewards directly into the token's economics on Solana, which extends to cross-chain activity.
Critical Post-Integration Considerations
After integrating, manage these key areas:
- Bridge Security & Liquidity: The security of the cross-chain bridge you choose (e.g., Wormhole) is paramount. Ensure it has sufficient liquidity for smooth transfers.
- Two-Community Management: You will now have a community on both Solana and Ethereum. Plan communication and updates for both groups.
- Monitoring Two Dexes: Track trading volume, liquidity depth, and price on both the Solana DEX (via Spawned) and the Ethereum DEX (e.g., Uniswap).
- Explaining the Process: Use your Spawned AI website to clearly explain how Ethereum users can bridge assets to buy your Solana token, reducing support queries.
Ready to Launch for Both Solana and Ethereum Users?
Integrating Spawned with Metamask opens your token to the largest combined audience in crypto. You gain Solana's speed with Ethereum's reach, all while building a sustainable project with built-in creator revenue and holder rewards. The 0.1 SOL launch fee and free AI website builder make starting more accessible than a traditional multi-chain launch.

Frequently Asked Questions
No, they do not need a native Solana wallet like Phantom. Metamask users interact with a wrapped version of your token on the Ethereum blockchain (or other EVM chains like Base). They buy, hold, and trade it directly within Metamask. If they want to move it to the Solana ecosystem to use in dApps, they would need to use the bridge to convert it back to the native Solana version, which would require a Solana wallet.
The 0.30% creator fee is enforced on the Solana side via Spawned's tokenomics. When a user bridges the token from Ethereum to Solana, they receive the native Spawned token. Any trade of this native token on a Solana DEX incurs the 0.30% fee. Trades of the wrapped token on Ethereum DEXs do not directly generate this fee, but they increase overall demand and volume, which drives bridging activity back to Solana where the fees are captured.
Token-2022 is an upgraded token program on Solana that enables advanced features like transfer fees. When your token 'graduates' from Spawned's initial launch phase, a 1% perpetual transfer fee can be enabled. This means 1% of the token amount is deducted on every transfer (not trade) and can be directed to a specified treasury wallet. This is a separate mechanism from the 0.30% trade fee and provides long-term project funding.
Yes, absolutely. The AI website builder included with your 0.1 SOL launch fee is not chain-specific. You should use it to create a central hub for your project. This site should host information for both Solana and Ethereum users, including the native Solana token address, the wrapped Ethereum contract address, bridge instructions, and links to relevant DEX pages for both chains.
It adds several steps, primarily involving setting up and securing a cross-chain bridge and providing initial liquidity on an Ethereum DEX. However, the core token creation and launch on Spawned remain the same simple, low-cost process. The added complexity is justified by the significant expansion of your potential buyer base from the Solana community to the much larger Ethereum and general EVM user ecosystem.
The 0.30% ongoing holder rewards are distributed to holders of the native Solana token. To be eligible for these rewards, users must hold the token on the Solana blockchain. An Ethereum user holding the wrapped version would not automatically receive these rewards. They would need to bridge their tokens to Solana to qualify. Your project's website should clearly communicate this distinction to set proper expectations.
