What Is the Sonic Network?

Sonic (S) is a next-generation blockchain designed for high performance, scalability, and developer accessibility. Built as an innovative Layer 2 solution based on Solana's architecture, Sonic delivers exceptional transaction throughput—processing up to 10,000 transactions per second (TPS) with finality achieved in under one second. This represents a major leap from Fantom’s previous finality time of 1–2 seconds.

Sonic aims to become a leading EVM-compatible platform that supports fast, low-cost transactions while maintaining robust security and decentralization.

Key Features of Sonic

What Is the S Token?

The $S token is the native cryptocurrency of the Sonic network. It plays a central role in securing the network and enabling decentralized governance. Key use cases include:

With a total supply capped at 175.3 billion tokens, $S will be gradually minted based on network demand. Additionally, users have the opportunity to earn $S through an airdrop program tied to activity on both Fantom and Sonic networks.

Choosing the Right Wallet for FTM to S Conversion

To convert FTM to S, you’ll need a non-custodial wallet—one where you retain full control over your private keys. These wallets ensure maximum security and autonomy during the upgrade process.

Recommended wallets that support the FTM-to-S conversion:

Ensure your chosen wallet supports both Fantom (FTM) and Sonic (S) tokens before proceeding.

Adhering to these guidelines helps prevent errors and ensures a smooth conversion experience.

Step-by-Step Guide: Converting FTM to S

Follow these three clear steps to upgrade your FTM tokens to S.

Step 1: Prepare Your Wallet

Start by setting up or accessing your non-custodial wallet (e.g., MetaMask, Rabby, or Trust Wallet).

Option A: Add Sonic Network via Chainlist

  1. Go to chainlist.org
  2. Search for “Sonic Mainnet”
  3. Click “Add to MetaMask” (works with most EVM-compatible wallets)
  4. Confirm the network addition in your wallet

Option B: Manually Add the Sonic Network

If Chainlist doesn’t work, add the network manually:

For mobile users (e.g., Trust Wallet), follow visual guides available on official Sonic resources to input these settings accurately.

Using Rabby Wallet? Here’s How:

  1. Download Rabby Wallet from its official site.
  2. Import your existing wallet using your 12-word recovery phrase.
  3. Connect Rabby to Chainlist and add the Sonic Mainnet.

Step 2: Connect to the Sonic Portal

Once your wallet recognizes the Sonic network:

  1. Visit the official Sonic upgrade portal: my.soniclabs.com/upgrade
  2. Click “Connect Wallet” and select your wallet provider
  3. Approve the connection request

Ensure you are on the correct URL—never connect your wallet to unverified websites.

Step 3: Upgrade FTM to S

Now it’s time to convert:

  1. Enter the amount of FTM you wish to upgrade
  2. Click “Upgrade”
  3. Confirm the transaction in your wallet

After confirmation, your FTM will be converted to S and appear in your wallet balance. Note: If your balance isn’t immediately visible but the transaction shows as confirmed on-chain, don’t panic—the display sync may take time due to ongoing network migration.

Use Sonicscan.org to verify your transaction status by entering your wallet address.

Frequently Asked Questions (FAQ)
