Sonic, the high-performance rebrand of Fantom, has emerged as a next-generation EVM Layer 1 blockchain built for speed, scalability, and developer empowerment. With capabilities like 10,000 transactions per second (TPS) and sub-second finality, Sonic is rapidly gaining traction among decentralized application (dApp) developers and crypto users alike. If you're holding $FTM tokens and want to upgrade them to $S — Sonic’s native token — the first step is adding the Sonic network to your MetaMask wallet.
This comprehensive guide walks you through everything you need to know about integrating Sonic into MetaMask, including manual and one-click setup methods, key network details, security tips, and answers to frequently asked questions. Whether you're a developer, investor, or DeFi enthusiast, this tutorial ensures you can securely access the Sonic ecosystem in minutes.
Can You Add Sonic to MetaMask?
Yes, absolutely. MetaMask supports all Ethereum Virtual Machine (EVM)-compatible blockchains, and Sonic is fully EVM-compatible. This means you can seamlessly connect your MetaMask wallet to the Sonic network, interact with dApps, stake $S tokens, and most importantly, upgrade your existing $FTM tokens to $S.
Once added, your wallet will recognize the Sonic blockchain just like Ethereum, Binance Smart Chain, or any other EVM network — enabling smooth transactions and interactions across decentralized platforms.

What Is Sonic?
Sonic is a cutting-edge Layer 1 blockchain engineered for ultra-fast performance and developer incentives. Formerly known as Fantom, the network underwent a strategic rebranding to reflect its advanced capabilities and renewed vision for scalable blockchain infrastructure.
Designed with efficiency in mind, Sonic delivers:
- 10,000 TPS throughput
- Sub-second transaction finality
- EVM compatibility for seamless dApp deployment
- Low-latency consensus mechanism
At the heart of the ecosystem is the $S token, which serves multiple critical functions:
- Governance voting
- Staking rewards
- Payment of transaction fees
- Participation in incentive programs
Users can upgrade their $FTM tokens to $S on a 1:1 basis through the official MySonic portal. For the first 90 days after mainnet launch, two-way swaps between FTM and S were allowed, enabling flexibility during the transition period. After this window closes, only one-way upgrades from FTM to S will be supported.
Key Features of the Sonic Ecosystem
One of Sonic’s standout innovations is the Sonic Gateway, a secure cross-chain bridge linking Sonic directly to Ethereum. This integration allows users and developers to tap into deep liquidity pools while maintaining strong asset protection protocols.
Additionally, Sonic offers powerful developer incentives:
- Fee Monetization Model: Developers earn up to 90% of the fees generated by their dApps.
- Innovator Fund: A $200 million allocation in $S tokens to support new projects building on the network.
- Airdrop Program: Another 200 million $S tokens are being distributed to early adopters, Opera users, and active participants in the ecosystem.
These initiatives make Sonic not just a high-speed blockchain but also a fertile ground for innovation and long-term growth.
How to Add Sonic to MetaMask
There are two ways to add the Sonic network to your MetaMask wallet: manually entering RPC details or using a one-click auto-configuration tool. Both methods are secure when done correctly — but verifying information is crucial to avoid phishing risks.
Method 1: Add Sonic to MetaMask Manually
To manually configure Sonic in MetaMask, follow these official network parameters:
Sonic Mainnet RPC Details:
- 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 at the top (usually showing "Ethereum Mainnet").
- Select "Add Network", then choose "Add a Network Manually".
- Fill in the fields using the details listed above.
- Double-check each entry for accuracy.
- Click "Save" or "Add Network".
After saving, your wallet will switch to the Sonic network, and you’ll be ready to interact with its ecosystem.
🔐 Security Tip: Always source RPC URLs and Chain IDs from official documentation only — such as docs.soniclabs.com — to prevent connecting to malicious networks.
Method 2: One-Click Setup (Recommended)
For faster configuration without manual input, use trusted one-click tools that auto-populate the correct network settings directly into MetaMask.
These tools generate a secure request that opens MetaMask with pre-filled data. You’ll still need to review and confirm the details before approving — giving you both convenience and control.
👉 Connect your wallet securely with streamlined setup options.
While convenient, always ensure the website prompting the connection is legitimate. Bookmark official domains and avoid clicking unverified links shared via social media or messaging apps.
Why Add Sonic to MetaMask?
Integrating Sonic into your MetaMask wallet unlocks several key benefits:
- Access to dApps: Use decentralized exchanges, lending platforms, NFT marketplaces, and more built on Sonic.
- Stake $S Tokens: Earn rewards by participating in network validation.
- Upgrade $FTM to $S: Seamlessly migrate your legacy tokens via the on-chain upgrade portal.
- Cross-Chain Interoperability: Leverage the Sonic Gateway to move assets between Ethereum and Sonic safely.
- Developer Opportunities: Build scalable applications with high fee revenue potential.
As Total Value Locked (TVL) continues to grow across the ecosystem since early 2025, early adopters gain increasing advantages — from airdrops to governance influence.
Frequently Asked Questions (FAQs)
Is MetaMask fully compatible with Sonic?
Yes. Since Sonic is EVM-compatible, MetaMask works seamlessly with it — just like it does with Ethereum, Polygon, or Avalanche. You can send tokens, interact with smart contracts, and manage your assets without issues.
Can I upgrade my $FTM tokens to $S after adding Sonic?
Absolutely. Once your MetaMask is configured for the Sonic network, visit the official MySonic upgrade portal to initiate the 1:1 token swap from $FTM to $S.
How do I upgrade from FTM to S?
If you hold $FTM on the Fantom Opera network, connect your wallet to the MySonic platform and follow the prompts. During the initial 90-day window post-launch,双向 swaps were allowed. Now, only upgrades from FTM → S are supported.
Which wallets support Sonic?
Any EVM-compatible wallet can connect to Sonic. Popular options include:
- MetaMask (most widely used)
- Rabby Wallet (enhanced UX and security)
- Trust Wallet (mobile-friendly)
Choose based on your preferred interface and security features.
Why should I verify network details before adding?
Entering incorrect RPC information can expose your wallet to scams or failed transactions. Always cross-check Chain ID, RPC URL, and explorer link from official sources before confirming.
Is there a cost to add Sonic to MetaMask?
No. Adding a custom network is completely free within MetaMask. However, actual transactions on the Sonic network will require gas fees paid in $S tokens.
Final Thoughts
Adding Sonic to MetaMask is a simple yet essential step for anyone looking to participate in this high-speed, developer-focused blockchain revolution. Whether you're upgrading legacy $FTM tokens, exploring new dApps, or staking for passive income, having proper wallet integration is the foundation of your journey.
