Soneium is emerging as a powerful Ethereum Layer 2 network built on Optimism’s OP Stack, developed through a strategic collaboration between Sony Group and Startale Labs. Designed to bridge the gap between Web2 and Web3, Soneium enables seamless integration of blockchain technology into mainstream applications—especially in gaming, digital entertainment, and decentralized finance (DeFi). One of the easiest ways to start exploring this innovative network is by connecting it to MetaMask, the most widely used self-custody wallet in the crypto ecosystem.
Adding Soneium to MetaMask unlocks access to its fast, low-cost transactions and EVM-compatible dApps. Whether you're a developer building on the network or a user eager to explore its ecosystem, integrating Soneium into your wallet is a straightforward process. This guide walks you through both automated and manual setup methods while providing essential context about the network’s capabilities and benefits.
Why Connect Soneium to MetaMask?
MetaMask serves as a gateway to thousands of decentralized applications across multiple blockchains. By adding Soneium, you gain direct access to a high-performance Layer 2 solution that combines Ethereum's security with enhanced scalability. The network supports advanced smart contracts, offers near-instant transaction finality, and maintains full compatibility with existing Ethereum tools and wallets.
With Soneium integrated into MetaMask, users can:
- Interact with native dApps in gaming and DeFi
- Transfer assets at minimal fees
- Deploy or test smart contracts using familiar development frameworks
- Benefit from EVM equivalence for smooth migration of existing projects

How to Add Soneium to MetaMask Using ChainList
The safest and most user-friendly way to add Soneium to MetaMask is via ChainList, a trusted aggregator of verified EVM-based networks developed by the DeFiLlama team. ChainList streamlines the connection process by automatically populating correct network parameters, reducing the risk of errors or exposure to malicious RPC endpoints.
Follow these simple steps:
- Open ChainList: Navigate to chainlist.org and click “Connect Wallet” to link your MetaMask.
- Search for Soneium: Use the search bar and type "Soneium".
- Select Network: From the results, find Soneium (Chain ID: 1868) and click “Add to MetaMask”.
- Confirm in Wallet: A MetaMask prompt will appear requesting permission to add the network. Review the details and confirm.
Once approved, Soneium will appear as an active network in your MetaMask interface, allowing immediate interaction with its ecosystem.
Manual Configuration: Soneium RPC Settings
For users who prefer full control over their wallet configuration—or if ChainList isn’t accessible—you can manually input Soneium’s network details into MetaMask. Always verify these values against official sources like Soneium’s documentation before proceeding.
Here are the required parameters:
- Network Name: Soneium
- New RPC URL: https://rpc.soneium.org/
- Chain ID: 1868
- Currency Symbol: ETH
- Block Explorer URL: https://soneium.blockscout.com/
To apply these settings:
- Open MetaMask and click the network dropdown (e.g., "Ethereum Mainnet").
- Select “Add Network” > “Add a Network Manually”.
- Enter the details above exactly as listed.
- Click “Save” to complete setup.
After saving, switch to the Soneium network and begin exploring compatible dApps or transferring testnet or mainnet ETH for use on-chain.

Frequently Asked Questions (FAQ)
Q: Is Soneium compatible with all EVM wallets?
A: Currently, Soneium is optimized for MetaMask, though other EVM-compatible wallets may work depending on configuration support.
Q: Do I need special tokens to use Soneium?
A: No. Soneium uses ETH as its native currency for gas fees, just like Ethereum. You can transfer ETH from any L1 or L2 wallet to pay for transactions.
Q: Is Soneium secure?
A: Yes. As an OP Stack chain, it inherits Ethereum’s consensus security and undergoes rigorous auditing. Its development team includes experienced engineers from Startale Labs and Sony.
Q: Can I build dApps on Soneium?
A: Absolutely. Developers can deploy Solidity-based smart contracts using Hardhat, Foundry, or any standard Ethereum development framework.
Q: What happens if I send funds to the wrong network?
A: Always double-check that MetaMask is set to the Soneium network before transacting. Sending funds to an incorrect chain may result in permanent loss.
Q: Where can I find official updates about Soneium?
A: For accurate news and technical resources, refer to soneium.org and their official documentation portal.
