Sonic's Successful Network Migration: What This Means for Fantom Opera

Since Sonic launched, the ecosystem has steadily migrated to the new network across users, builders, liquidity, and validators. That transition has been successful, and Sonic now serves as the primary home of the ecosystem.

Sonic was built as a new chain with a stronger technical foundation and improved performance, rather than as a continuation of Opera. Over time, Opera’s remaining role has become limited as the ecosystem established itself on Sonic.

The ecosystem has also had substantial time to complete this move. Migration incentives were introduced in June 2024, the transition was outlined publicly in September 2024, and Sonic launched on December 18, 2024. Since then, users, partners, and infrastructure providers have had an extended window to migrate with low disruption. Validator migration has already taken place, and Opera now remains as legacy infrastructure.

Sunsetting Opera is also a security and operational decision. It allows us to close the Opera FTM → S bridge, reduce legacy bridges and infrastructure, and focus resources more efficiently on Sonic’s security and operations.

This does not mean Fantom Opera data or chain history are being deleted. It refers to the retirement of remaining legacy Opera infrastructure. Chain data and historical records will remain preserved.

This DOES NOT affect the ERC-20 FTM → S route or the Sonic Gateway. The ERC-20 FTM → S route will remain supported while some exchanges complete their migration.

Users still relying on Fantom Opera mainnet or the Opera FTM → S bridge should complete any necessary transfers before 5:00 PM GMT on June 30, 2026. Failure to do so will prevent any further migration from FTM to S.

With Opera sunset, the transition to Sonic will be effectively complete. The network, validator base, liquidity, and ecosystem activity have already moved, and this step closes out the remaining legacy infrastructure associated with Opera.
