Sonic Declares Migration Complete, Sets June 30 Deadline for Fantom Opera Bridge Closure
Sonic Labs announced on April 7, 2026, that its migration from Fantom Opera is complete, with users, validators, builders, and liquidity now operating on the Sonic network.

Sonic Labs announced on April 7, 2026, that its migration from Fantom Opera is complete, with users, validators, builders, and liquidity now operating on the Sonic network. A hard deadline is now in effect: anyone still holding FTM on the Fantom Opera network must bridge their tokens to Sonic's native S token before June 30, 2026, at 5:00 PM GMT or lose access to that migration route permanently.
The transition has been underway since December 18, 2024, when Sonic launched as a standalone Layer 1 blockchain rather than an upgrade to Opera. Sonic Labs said it pursued a clean architectural break because the performance improvements it wanted, including higher transaction throughput, faster finality, and lower node operating costs, could not be retrofitted onto the existing network. According to the team, Sonic can process between 10,000 and 20,000 transactions per second, compared to roughly 2,000 on Opera. Validator node costs have been reduced by 66 percent and RPC node costs by 96 percent. "Sonic was built as a new chain with a stronger technical foundation and improved performance, rather than as a continuation of Opera," the company said in its April 7 announcement.
The FTM-to-S conversion rate remains 1:1, as it has been since launch, but the swap has been one-way since March 31, 2025. S tokens cannot be converted back to FTM. After June 30, the Opera bridge will close, leaving only two remaining routes for any holdouts: the ERC-20 bridge (which requires moving funds to Ethereum first) and the Sonic Gateway. Both are more technically complex and carry higher transaction costs than the direct Opera bridge. Exodus wallet has separately announced it will end support for Fantom Opera on August 1, 2026, adding pressure for retail users who have not yet moved. Fantom Opera itself is not being shut down, but Sonic Labs described its remaining role as "limited" and said all development resources have been redirected to Sonic.
The major centralized exchanges handled this transition automatically for their customers. Binance completed the FTM-to-S swap and relabeled trading pairs on January 16 and 17, 2025. Kraken finished its migration on May 10, 2025. Other platforms including Crypto.com, Bybit, Bitget, Binance.US, and MEXC have also completed the process. Users who held FTM on those platforms during the swap period are already holding S and have nothing further to do. The concern is narrower: anyone using self-custody wallets on the Opera network, or regional exchanges that did not handle the swap automatically, must take manual action before the June 30 deadline.
For users in South Asia and Africa, the stakes are practical. Binance is the dominant exchange by volume across both regions, so most retail holders who were active on a major platform were migrated without any action required. However, crypto participation in markets like Nigeria, Kenya, India, and Pakistan often involves peer-to-peer platforms and smaller wallets, some of which may not have processed the swap automatically. No public on-chain data is available to quantify how many users in these markets still hold FTM on Opera, so the scale of remaining exposure is uncertain. Supporting context from the broader region indicates continued growth in crypto activity: Binance P2P remittance volume in Pakistan grew 18.7 percent in 2025, and Nigeria expanded its registered virtual asset service provider count from 19 to 25 under its regulatory sandbox framework in the same period. Users who still hold FTM on Opera must use the direct bridge before it closes. After June 30, the only fallback is the ERC-20 route through Ethereum, which involves additional steps and higher gas fees that can be a real barrier in cost-sensitive markets. ZebPay, an India-focused exchange, has covered the rebrand, indicating some awareness of the transition in that market.
On-chain metrics paint a complicated picture for the network overall. The S token is trading at approximately $0.040 as of April 7, 2026, with a market capitalization of roughly $152 million and a fully diluted valuation near $156 million. Total value locked in Sonic's DeFi ecosystem peaked at approximately $1.1 billion in May 2025, reached within 66 days of the mainnet launch. That figure had fallen to around $34 million as of March 2026, a decline of roughly 97 percent from peak. Sonic now ranks approximately 43rd globally among blockchains by TVL. The token is down about 1 percent over the past seven days, underperforming a broader market that gained slightly in the same period.
When Sonic launched in December 2024, the project introduced three developer incentive programs: an Innovator Fund of up to 200 million S tokens, a 190.5 million S airdrop for early adopters representing 6 percent of total supply, and a Sonic Boom bounty program. At the token's current price of approximately $0.04, the Innovator Fund carries a real-dollar value of roughly $8 million, substantially reduced from its notional value at the time of announcement. In March 2026, Sonic Labs took additional steps to rebuild liquidity by launching USSD, a dollar-pegged stablecoin backed 1:1 by tokenized U.S. Treasury assets, with backing provided through BlackRock BUIDL, Superstate USTB, and WisdomTree products. USSD is built with Frax Protocol and distributes across more than 10 blockchains via LayerZero. Whether those programs can attract sustained on-chain activity will determine how relevant Sonic becomes as a practical network, particularly in markets where low fees and fast settlement have historically been the primary draw.
