Sonic Labs has officially announced the definitive decommissioning of the Fantom Opera network, scheduled for July 1, 2026. As the ecosystem transitions toward the high-performance Sonic network, developers and users are required to finalize the transfer of their digital assets and operational infrastructure to the new environment. The shutdown marks the conclusion of a multi-year migration process aimed at upgrading the blockchain’s throughput and scalability.
Migration Timeline and Network Transition
According to the statement released by Sonic Labs, the Fantom Opera network will cease all operations at 17:00 GMT on June 30, 2026. This move comes as a response to the successful migration of the vast majority of liquidity, validators, and decentralized applications (dApps) to the Sonic mainnet. To ensure a smooth transition, the development team has established specific protocols for those who have yet to move their holdings.
- The cutoff for network operations is strictly set for early July 1 (Beijing time).
- Validators are expected to fully transition their nodes to the Sonic architecture.
- Liquidity providers must migrate pools to maintain trading activity and minimize slippage.
Asset Conversion and Bridge Functionality
Despite the cessation of the Opera network's block production, Sonic Labs clarified that certain critical financial gateways will remain functional to protect user funds. The Sonic cross-chain bridge will continue to operate, allowing for the movement of assets between supported chains. Furthermore, the conversion mechanism for the ERC-20 version of FTM into the new S tokens will not be impacted by the network shutdown.
This ensure that holders of the legacy Ethereum-based token can still participate in the new ecosystem without immediate time pressure on the conversion itself.
Strategic Evolution Toward Sonic
The transition from Fantom to Sonic represents a significant technological pivot for the project. By focusing resources on a single, more advanced chain, the developers aim to eliminate fragmentation and enhance the overall efficiency of the DeFi ecosystem.
As users, developers, liquidity, and validators fully migrate to the Sonic network, the Fantom Opera network will officially cease operations.
The decommissioning of the legacy chain is a standard procedure in blockchain evolution, often necessary to prevent security risks associated with maintaining outdated infrastructure. Users are encouraged to verify their wallet balances and ensure all smart contracts or automated bots are updated to point toward the Sonic RPC endpoints before the June 30 deadline.
