Migration FAQ

Below are the most frequently asked questions specifically regarding the migration process from Fantom Opera to Sonic.

What if I hold FTM somewhere other than Opera?

Check out the Sonic Upgrade Handbook.

Does the upgrade portal handle app token migrations?

No, the official upgrade portal only supports FTM to S migration on Opera. Each project must implement its own migration solution.

What happens to my LP positions during migration?

LP positions must be broken, tokens migrated individually, and positions re-created on Sonic.

How long will two-way migration be available?

Two-way migration between FTM and S will be available for 90 days following launch, after which it will switch to one-way from FTM to S.

What happens if I don't migrate during the two-way period?

You'll still be able to upgrade from FTM to S but not back to FTM from S.

Will my transaction history migrate?

No, transaction history remains on the original chain. Sonic is a fresh chain with no history.

How do I know the migration method used by a token I'm holding?

Check your project's announcements or contact the team directly.
