Sonic, the rebranded evolution of Fantom, is making waves in the blockchain space as a high-performance EVM Layer 1 network. With capabilities like 10,000 transactions per second (TPS) and sub-second finality, Sonic offers a next-generation infrastructure for developers and users alike. If you're holding $FTM tokens and plan to upgrade them to $S, or simply want to explore decentralized applications (dApps) on this powerful new chain, you’ll first need to add Sonic to MetaMask.
This guide walks you through everything you need to know—why Sonic matters, how to connect it securely to your MetaMask wallet, and what steps come next. Whether you prefer manual configuration or a faster one-click method, we’ve got you covered.
Can You Add Sonic to MetaMask?
Yes, absolutely. MetaMask fully supports Sonic, as it’s an Ethereum Virtual Machine (EVM)-compatible blockchain. This means your existing MetaMask wallet can seamlessly interact with the Sonic network without requiring a new wallet or complex setup.
Once added, you’ll be able to:
- View and manage your $S tokens
- Interact with native dApps
- Participate in staking
- Use the on-chain upgrade feature to convert $FTM to $S

What Is Sonic?
Sonic is a high-speed, scalable EVM Layer 1 blockchain built for performance and developer empowerment. Formerly known as Fantom, the network has undergone a major technical and strategic overhaul, emerging as a more efficient, secure, and incentive-rich ecosystem.
Key Features of Sonic
- 10,000 TPS throughput: Enables fast transaction processing ideal for DeFi, gaming, and NFT platforms.
- Sub-second finality: Transactions are confirmed almost instantly, improving user experience.
- EVM compatibility: Works with all standard Ethereum tools and wallets like MetaMask.
- Native token ($S): Used for governance, staking rewards, gas fees, and ecosystem participation.
- 1:1 FTM-to-S upgrade: Holders of $FTM on the Opera network can upgrade their tokens directly to $S.
Sonic Gateway & Cross-Chain Connectivity
One of Sonic’s standout features is the Sonic Gateway, a secure two-way bridge connecting Sonic to Ethereum. This allows seamless transfer of assets while maintaining deep liquidity and enhanced security protocols. The bridge ensures that users can move funds safely between chains, opening up broader DeFi opportunities.
Developer Incentives That Drive Innovation
Sonic isn’t just user-friendly—it’s developer-first.
- Fee Monetization Model: Developers earn up to 90% of the fees generated by their dApps.
- Innovator Fund: Up to 200 million $S allocated to fund promising new projects.
- Airdrop Program: A total of 200 million $S distributed to early adopters across both Opera and Sonic networks.
These initiatives are accelerating adoption and fostering a vibrant ecosystem of builders and users.
How to Add Sonic to MetaMask
There are two reliable ways to add Sonic to your MetaMask wallet: manually entering network details or using a one-click auto-configuration tool.
Option 1: Add Sonic to MetaMask Manually
Adding the network manually gives you full control over the configuration process and is ideal if you prioritize security verification.
Sonic Network RPC Details
Before proceeding, ensure you have the correct network information from the official Sonic documentation:
- Network Name: Sonic
- New RPC URL:
https://rpc.soniclabs.com - Chain ID:
446 - Currency Symbol:
S - Block Explorer URL:
https://explorer.soniclabs.com
Step-by-Step Instructions
- Open your MetaMask wallet (browser extension or mobile app).
- Click on the network dropdown (usually shows "Ethereum Mainnet").
- Select “Add Network”, then choose “Add a Network Manually”.
- Fill in the fields using the details listed above.
- Click “Save” or “Add” to confirm.
Once saved, your wallet will connect to the Sonic network. You can now view $S balances and interact with dApps.
🔐 Always double-check the RPC URL and Chain ID from official sources before saving. Entering incorrect details could lead to fund loss or phishing risks.
Option 2: One-Click Setup for Instant Connection
For faster access, use a trusted one-click integration service that automatically configures MetaMask with verified Sonic network parameters.
This method skips manual entry and reduces human error. When prompted:
- Approve the connection request in MetaMask.
- Confirm the network details match the official specs (especially Chain ID: 446).
- Switch to the Sonic network after setup completes.
👉 Connect your wallet securely with streamlined setup tools.
While convenient, always verify the source of any auto-configuration link. Stick to official domains like soniclabs.com or trusted partners.
Upgrading $FTM to $S Tokens
If you hold $FTM on the Fantom Opera network, you can upgrade them to $S via the MySonic portal.
Upgrade Timeline & Rules
- During the first 90 days after mainnet launch, users can swap between $FTM and $S in both directions.
- After this period, only one-way upgrades (FTM → S) will be allowed.
- The conversion ratio is 1:1, ensuring no value dilution during migration.
To begin:
- Ensure your wallet contains $FTM on the Opera network.
- Connect your MetaMask (with Sonic added) to the MySonic upgrade interface.
- Follow the prompts to complete the swap.
This process locks your $FTM on Opera and mints an equivalent amount of $S on the Sonic chain.
Why Adding Sonic to MetaMask Matters
As Sonic’s ecosystem grows—evidenced by rising Total Value Locked (TVL) and expanding dApp offerings—early access becomes crucial. By adding Sonic to MetaMask now, you position yourself at the forefront of innovation on a chain designed for speed, scalability, and real economic incentives.
You’ll gain access to:
- High-yield DeFi protocols
- NFT marketplaces optimized for low latency
- Staking opportunities with attractive APYs
- Governance participation using $S tokens
👉 Stay ahead in the evolving blockchain landscape—integrate cutting-edge networks easily.
