Integrating MetaMask with Your Solana Token Launched on Spawned
This guide provides a developer-focused walkthrough for integrating MetaMask wallet functionality with a Solana token launched via the Spawned platform. We cover the technical considerations for cross-chain awareness, fee structures specific to Spawned (like the 0.30% creator and holder rewards), and methods to connect your dApp's frontend. While native Solana wallets like Phantom are primary, MetaMask integration expands your token's accessibility.

Spawned provides an AI-powered platform that makes building fast, simple, and accessible to everyone.
Should You Integrate MetaMask with Your Spawned Token?
A pragmatic assessment for developers deciding on integration scope.
For most projects launching exclusively on Solana via Spawned, deep MetaMask integration is a secondary priority. Your primary focus should be on the Solana ecosystem and wallets like Phantom. However, integrating MetaMask support is recommended if your target audience heavily uses Ethereum-based wallets or if your long-term plan involves a multi-chain presence. This integration is less about direct transaction signing on Solana and more about user education and bridging pathways. The unique Spawned benefits—0.30% creator revenue, 0.30% holder rewards, and the included AI website builder—are anchored on Solana. Therefore, treat MetaMask integration as a convenience layer for user onboarding, not a core transactional requirement. For projects aiming for a broad user base, this layer can reduce friction.
The Technical Reality: Solana vs. EVM Ecosystems
Understanding the fundamental blockchain differences is the first step.
MetaMask is an Ethereum Virtual Machine (EVM) wallet. Your token, launched on Spawned, is a Solana SPL token (or Token-2022 post-graduation). These are different, incompatible blockchain environments. MetaMask cannot natively hold Solana tokens or sign Solana transactions. Therefore, 'integration' typically means one of two approaches:
- Bridging Awareness: Your application's interface detects a MetaMask wallet and guides the user to a cross-chain bridge (like Wormhole or Portal) to move assets from an EVM chain to Solana, where a Solana wallet takes over.
- Wallet Abstraction: Using toolkits or middleware that abstract away the blockchain complexity, allowing a user to interact with your Solana dApp using an EVM wallet signature. This is more advanced.
The Spawned launch fee of 0.1 SOL and all subsequent trade fees occur on the Solana network. A user must ultimately use SOL to pay for transactions, regardless of their starting wallet.

Key Spawned Features & Integration Impact
How Spawned's unique model interacts with a multi-wallet setup.
- Creator Revenue (0.30% per trade): This fee is collected on the Solana network. The integration must ensure all trades happen via Solana smart contracts, whether the user started with MetaMask or not.
- Holder Rewards (0.30% ongoing): Similarly, this reward mechanism is implemented on Solana. Your integration needs to track holdings via Solana, not EVM addresses.
- AI Website Builder: This Spawned tool helps create your project's homepage. You should prominently feature your token's Solana contract address and purchasing instructions on this site, alongside any bridging guides for EVM users.
- Post-Graduation (1% fee): After moving from the launchpad to a full Token-2022 program, the 1% perpetual transfer fee is enforced on Solana. Your MetaMask integration flow must make users aware that accepting this token on an EVM chain means bypassing this fee mechanism.
Direct Solana vs. Bridged-from-EVM: A User Experience Comparison
Weighing the practical differences for end-users.
| Aspect | User with Phantom (Direct) | User Starting with MetaMask (Bridged) |
|---|---|---|
| Time to First Trade | < 1 minute. Fund with SOL and trade. | 5-10+ minutes. Requires bridging, which has wait times and dual gas fees (EVM + Solana). |
| Cost Efficiency | Pays only Solana transaction fees (~$0.001). | Pays Ethereum/EVM gas for bridge approval + Solana fees. Can cost $10+ on Ethereum L1. |
| Access to Rewards | Immediate. Holder rewards accrue from first Solana purchase. | Delayed until assets are on Solana. Misses reward accrual during bridge process. |
| Developer Support | Full support from Spawned, Solana tooling, and wallets. | Reliant on third-party bridge security and uptime. Increased support complexity. |
| Spawned Fee Eligibility | 100% eligible. All fees are correctly applied. | 100% eligible, but only after assets are on Solana. |
This comparison shows why guiding users to a native Solana wallet first is optimal, as detailed in our guide on how to launch a gaming token on Solana.
Troubleshooting Common Integration Issues
Anticipate and solve these frequent user challenges.
Problem: User connects MetaMask but cannot see their Spawned token balance. Solution: Explain that the token must be bridged to Solana. Their balance exists on Solana at their associated Solana wallet address, not their MetaMask Ethereum address.
Problem: Bridge transaction succeeds, but token doesn't appear in user's Phantom wallet. Solution: Instruct the user to add the token mint address manually in Phantom. Provide the mint address from your Spawned launch dashboard. Also, verify the bridge destination address matched the user's Solana wallet public key.
Problem: User wants to pay the 0.1 SOL launch fee on Spawned using MetaMask. Solution: This is not possible. The launch fee requires SOL on the Solana network. The user must acquire SOL and send it to a Solana wallet, or use a service that offers cross-chain SOL purchases.

Frequently Asked Questions
No, not directly. MetaMask is designed for EVM-based chains like Ethereum or Base. Tokens launched on Spawned are Solana SPL tokens. To 'hold' them in MetaMask, the tokens must be wrapped into an EVM-compatible format (like a Wormhole-wrapped asset) via a bridge and added as a custom ERC-20 token. However, for interacting with the original Solana token's features and fees, holding it in a Solana wallet is necessary.
No. The 0.30% creator fee and the 0.30% holder reward are mechanisms programmed into the Solana token. When a user bridges tokens to an EVM chain (like Ethereum), they are holding a bridged representation. Trades of that bridged token on EVM decentralized exchanges do not trigger the original Solana fee logic. Fees are only generated from trades that occur on Solana decentralized exchanges.
The most cost-effective path is for the user to avoid Ethereum mainnet entirely. They should: 1) Purchase SOL on a centralized exchange that supports Solana withdrawals. 2) Withdraw that SOL directly to a new Solana wallet (like Phantom). 3) Use that SOL to buy your token directly on a Solana DEX. This avoids expensive EVM gas fees for bridging. Guide users toward this method on your website.
The 1% perpetual fee, enabled via Solana's Token-2022 program after graduation, is a property of the token on the Solana blockchain. It applies to transfers on Solana. If a token is bridged to an EVM chain, the bridged version is a separate contract and is not subject to this Solana-specific fee. The integration does not affect the fee; rather, moving the asset to another chain circumvents it for transactions on that other chain.
Absolutely. This is a primary use case for the included AI website builder. You can generate a professional landing page that clearly explains your token's Solana nature, provides the correct contract addresses, and has dedicated sections titled 'MetaMask Users Start Here' with step-by-step bridging instructions. This saves you the $29-99/month a separate website builder might cost.
Yes, if you are launching a token for an Ethereum or Base-based game, MetaMask is the primary wallet, not a secondary one. In those cases, your integration would be native. 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) cover those native launch processes. This guide specifically addresses the scenario of a Solana token (from Spawned) seeking to accommodate EVM wallet users.
Typically, no major backend changes are required if your smart contracts are on Solana. Your backend likely already listens to Solana events. The integration is frontend-focused, managing wallet connections and user guidance. Your backend should, however, be capable of associating a user's EVM address (from MetaMask) with their Solana address for cross-reference, if needed for your application's logic.
