FAQs

1. Is MetaMask fully compatible with Sonic?

Absolutely. MetaMask supports all EVM networks, including Sonic, which means you can seamlessly interact with the network and enjoy its advanced features.

 

2. Can I upgrade my $FTM tokens to $S after adding Sonic?

Yes, once you have Sonic added to MetaMask, you can access the on-chain upgrade feature to convert your $FTM tokens to $S on a one-to-one basis.

 

3. How to upgrade from FTM to Sonic?

If you hold FTM tokens on the Fantom Opera network, you can use the MySonic upgrade portal to swap them with Sonic (S) tokens.

After that period, the upgrade will only let you convert FTM tokens to S tokens.

The Sonic network is EVM-compatible, so virtually any wallet that supports Ethereum Virtual Machine networks can be used. Popular choices like MetaMask are widely adopted, while Rabby stands out as a recommended alternative due to its user-friendly interface. This compatibility means you have a range of options; such as Trust Wallet and others, to securely manage your S tokens and interact with the Sonic ecosystem.

 

5. Why is verifying the network details important?

Ensuring you use the correct RPC details from the official Sonic documentation helps avoid any configuration errors and keeps your wallet secure.
