Fantom's legacy Opera chain will permanently cease operations on June 30, 2026, impacting Stargate V1 liquidity providers and requiring asset migration.

Fantom's legacy Opera chain will permanently cease operations on June 30, 2026, at 17:00 GMT, marking the end of the original mainnet that supported the Fantom ecosystem [1]. This shutdown is part of a migration process toward the newer Sonic chain, with users and liquidity providers given less than three months to move their assets [1]. Sonic Labs, formerly the Fantom Foundation, announced the date, signaling the final stage of a transition that has been ongoing for over a year [1].

**Key takeaways**
*   Fantom's legacy Opera chain will shut down permanently on June 30, 2026 [1].
*   Users with assets on Opera, including liquidity providers in Stargate V1, must migrate them before the deadline [1].
*   The Sonic chain launched in January 2025, and the migration process has been underway for over a year [1].
*   Historical on-chain records from Opera will remain accessible after the shutdown [1].

## The End of an Era for Fantom Opera

The decommissioning of the Fantom Opera network means its supporting infrastructure will go offline permanently after June 30, 2026 [1]. Sonic Labs rebranded from the Fantom Foundation in August 2024, indicating a strategic shift towards the Sonic chain, which launched its mainnet on January 7, 2025 [1]. By early 2026, most migration activities were reportedly complete, which is why the formal shutdown announcement did not cause significant market disruption [1]. The ERC-20 FTM to S token conversion mechanism and the Sonic Gateway bridge remain operational, and historical data from the Opera network will still be accessible [1].

## Stargate V1 Liquidity Providers Face Urgent Action

A more immediate concern is for liquidity providers (LPs) who still have funds in protocols on Fantom Opera, particularly Stargate V1 [1]. Stargate V1 pools on Fantom currently hold an estimated $486,000 to $576,000 in total value locked [1]. If these LPs do not withdraw their funds before the June 30 deadline, they risk disruptions when the network infrastructure ceases to function [1]. Stargate V1 is an older iteration of the cross-chain liquidity protocol, distinct from its current V2 version [1, 2]. These V1 positions on Fantom may represent legacy holdings that some LPs have overlooked due to factors like gas costs and the complexity of managing assets across multiple chains [1].

## Why it matters

The shutdown of the Fantom Opera chain necessitates that all users, including those with assets in Stargate V1 pools or other DeFi protocols, migrate their holdings to the Sonic chain or elsewhere before June 30, 2026 [1]. While the conversion mechanisms and bridge to Sonic remain functional, failure to act could lead to the loss of access to funds currently deployed on the legacy network [1]. The total capital at risk in Stargate V1 alone, approaching half a million dollars, highlights the importance of this migration for individual holders [1]. Stargate V2, launched to address limitations in V1 such as high gas fees and scalability, offers improvements like transaction batching and an AI Planning Module for capital efficiency [2].
