Spawned & Metamask Integration Guide for Token Developers
This guide explains how developers can connect their Spawned-launched Solana tokens with the Ethereum ecosystem through Metamask. While Spawned operates primarily on Solana, strategic integration with Metamask opens access to Ethereum's vast user base and liquidity. We cover wallet bridging, cross-chain liquidity strategies, and the specific advantages of Spawned's fee structure for ongoing projects.

The Solution
Spawned provides an AI-powered platform that makes building fast, simple, and accessible to everyone.
The Developer Verdict: Is Spawned-to-Metamask Integration Right for You?
Should you bridge your Spawned token to work with Metamask? Here's the straightforward assessment.
For developers targeting a multi-chain audience, integrating a Spawned-launched token with Metamask is a logical growth step, but it introduces complexity. If your primary community is on Solana, focus on Spawned's native advantages: the 0.30% ongoing creator revenue, built-in holder rewards, and the included AI website builder. If expanding to Ethereum is critical for your project's adoption (e.g., targeting established DeFi protocols or NFT communities), then integration becomes essential. The 0.1 SOL (~$20) launch fee on Spawned is just the start; budget for Ethereum gas fees and bridge costs. Learn about launching gaming tokens on different chains.
Why Connect a Solana Token to an Ethereum Wallet?
Metamask is the default gateway for millions of users into Web3, but it's built for Ethereum Virtual Machine (EVM) chains. A token launched on Spawned exists natively on Solana, which uses a different architecture. Integration isn't about making Spawned work in Metamask for Solana transactions (that's limited), but about making your token's value accessible through Metamask on other chains. This is about audience expansion. By creating a bridged version of your token on an EVM chain like Ethereum, Base, or Polygon, you allow Metamask users to hold and trade it without leaving their preferred wallet. This can significantly increase your token's reach and liquidity pools.
Step-by-Step: Bridging Your Spawned Token to Work with Metamask
A practical walkthrough for creating an EVM-compatible version of your token.
Follow these steps to create an Ethereum-compatible version of your Spawned-launched token. Prerequisites: Your SPL token live on Solana, a Metamask wallet with ETH for gas, and the original token's mint authority.
- Choose a Cross-Chain Bridge: Select a reputable bridge like Wormhole or Portal (by Allbridge). These protocols lock your Solana tokens and mint a corresponding ERC-20 version on your target EVM chain.
- Connect Wallets: Connect your Solana wallet (e.g., Phantom) holding the original tokens and your Metamask wallet (set to the target network like Ethereum Mainnet) in the bridge interface.
- Initiate the Bridge: Specify the amount of your SPL token to bridge. The bridge will lock them in a Solana vault and mint the wrapped ERC-20 tokens to your Metamask address. This creates a 1:1 pegged representation.
- Add Token to Metamask: Once the transaction completes, you'll need to add the new token's contract address to Metamask to view it. The bridge will provide this address.
- Provide Initial Liquidity: For the bridged token to be usable, you must create a liquidity pool on an EVM DEX like Uniswap (Ethereum) or PancakeSwap (BNB Chain). This requires depositing both the bridged tokens and the native chain's currency (e.g., ETH).
Note: The bridged token is a separate contract. Spawned's 0.30% fees and rewards apply to the original Solana token, not the bridged version.
Spawned (Solana) vs. Bridged (EVM) Token: Key Differences
Your token lives a double life. Here’s what changes and what stays the same.
Understanding the distinction between your native Spawned token and its bridged counterpart is crucial for management.
| Aspect | Native SPL Token (on Spawned/Solana) | Bridged ERC-20 Token (on EVM/Metamask) |
|---|---|---|
| Network | Solana | Ethereum, Base, Polygon, etc. |
| Wallet Used | Phantom, Solflare | Metamask, Rabby |
| Creator Fees | 0.30% per trade on Solana DEXs | Set separately on the EVM token contract (often 0%) |
| Holder Rewards | 0.30% ongoing via Spawned | Not applicable unless coded into EVM contract |
| Launch Cost | 0.1 SOL + optional LP | Bridge fees + EVM gas + LP deployment costs |
| Governance | Spawned's Token-2022 program for fees | Standard ERC-20, upgradeable if specified |
| Website Builder | Use Spawned's included AI tool | Can link to the same site or a separate page |
The bridged token's value is derived from the locked Solana tokens. Your project now manages two communities.
4 Strategic Benefits of Spawned + Metamask Integration
While complex, bridging offers tangible advantages for project growth.
- Access a Massive User Base: Metamask has over 30 million monthly active users. A bridged token lets you tap into this ecosystem without asking users to switch wallets or buy SOL first.
- Diversify Liquidity: Liquidity on both Solana (via Raydium, Orca) and Ethereum (via Uniswap) protects your project from network congestion or high fees on a single chain and can improve price stability.
- Enable Cross-Chain Utilities: You can build features that use the bridged token in Ethereum DeFi protocols for lending, yield farming, or as collateral, adding utility beyond Solana's ecosystem.
- Leverage Spawned's Economics on Solana: You can direct your core community to the Solana side to benefit from Spawned's 0.30% holder rewards and lower transaction fees, while using the bridged version primarily for outreach and liquidity depth.
Troubleshooting Common Integration Issues
Problem: Users can't see the bridged token in Metamask. Solution: They must manually add the token using its correct contract address from the bridge provider. Verify the network in Metamask matches the destination chain.
Problem: Large price difference between Solana and Ethereum markets. Solution: This is an arbitrage opportunity. Encourage arbitrageurs to use the bridge to balance supply. Ensure sufficient liquidity on both sides to minimize slippage.
Problem: High gas fees make small transactions on Ethereum impractical. Solution: Consider bridging to a Layer 2 like Base or Arbitrum instead of Ethereum Mainnet. Promote this bridged version for smaller, community-focused transactions. See a guide for Base.
Problem: How to manage community across two chains. Solution: Use Spawned's AI website builder to create a clear hub that explains both versions, provides links to both DEXs, and directs holders to the Solana version for rewards.

Frequently Asked Questions
Not directly for most actions. Metamask's Solana support is limited. To trade or hold the native SPL token on Solana, users should use a Solana-native wallet like Phantom. Metamask integration primarily refers to holding and trading a bridged, ERC-20 version of your token on Ethereum or other EVM networks.
No. Spawned's fee mechanism is built into the SPL Token-2022 program on Solana. The bridged ERC-20 token on Ethereum is a separate contract. Any creator fees on the Ethereum side must be coded into that new contract during deployment, which typically involves a separate fee structure or may be set to 0%.
Beyond the initial bridge and liquidity provisioning costs, you must monitor the bridge's security. There are no direct 'maintenance' fees, but you should budget for Ethereum gas fees if you need to adjust the bridged token's contract (like updating metadata) and for providing liquidity incentives to keep pools active on both chains.
It depends on your priorities. Launching directly on an EVM chain (like Ethereum or Base) simplifies access for Metamask users but often comes with higher launch costs and gas fees. Launching on Spawned (Solana) gives you lower costs (0.1 SOL fee), built-in holder rewards, and an AI website builder. You can then bridge to EVM. [Compare Solana and Ethereum launches](/use-cases/token/how-to-launch-gaming-token-on-solana).
The included website builder lets you create a single, professional site that clearly explains both the native Solana token and the bridged Ethereum token. You can embed widgets for both Raydium (Solana) and Uniswap (Ethereum) pools, provide separate wallet connection options, and direct users to the chain that best suits their needs, all without a monthly subscription fee.
Token graduation on Spawned moves the SPL token to a permanent mint authority and enables the 1% perpetual fee. This change only affects the Solana-native token. The bridged tokens on Ethereum remain backed by the locked, pre-graduation SPL tokens in the bridge vault. The bridge protocol manages this relationship independently of Spawned's graduation process.
