How to Bridge to Sonic

Can I Bridge to Sonic?

Yes, users can bridge to Sonic by upgrading FTM to S tokens on a 1:1 basis through the official upgrade portal on the Fantom network.

This upgrade process functions as the only current method of asset transfer to Sonic, as the Sonic Gateway bridge is not yet live and third-party bridge options are unavailable.

How to Bridge to Sonic

You can bridge to Sonic by upgrading FTM tokens to S tokens through the Sonic upgrade portal on the Fantom network. This is currently the only way to move assets into Sonic. The portal also supports swapping S tokens back to FTM, allowing flexibility until the Sonic Gateway bridge is live.

Here’s how to upgrade and bridge FTM to S:

1. Go to the Upgrade Portal: Access the Sonic upgrade portal on the Fantom network.
2. Connect Your Wallet: Use a supported wallet like MetaMask to connect.
3. Select FTM to S: Choose the option to upgrade your FTM tokens to S.
4. Enter and Approve: Specify how much FTM you want to upgrade and approve the transaction in your wallet.
5. Wait for Confirmation: The upgrade process may take up to an hour to complete. Once done, your S tokens will appear in your wallet.

What are the Fees?

Upgrading FTM to S tokens through the Sonic upgrade portal costs a fixed 0.1 FTM fee, plus Fantom network gas fees, usually less than $0.10.

There are no platform fees, making this a straightforward and low-cost method to move assets into Sonic.

What is Sonic Gateway?

Sonic Gateway is a decentralized bridge for secure asset transfers between Ethereum and Sonic. It processes transactions in gas-efficient "heartbeats" every 10 minutes from Ethereum to Sonic and hourly in reverse, with a Fast Lane option for instant transfers.

Operated by Sonic's validator network, it ensures decentralization and includes a 14-day fail-safe for asset recovery in case of downtime. Currently under development, the Gateway is being led by Andre Cronje.

Bottom Line

The only way to bridge to Sonic is by upgrading FTM to S tokens through the Fantom network. 

While this limitation may be inconvenient, users will need to wait for the Sonic Gateway’s launch to access a decentralized bridging solution.
