What is Sonic (S)
Sonic is an Ethereum-compatible layer-1 blockchain born from the transformation of Fantom, one of the most used networks in the decentralised finance season of 2021. The project announced the name change in August 2024 and switched on the new network on 18 December 2024: not an upgrade of the old one, but a new infrastructure, with a rewritten client, a lighter data store and a bridge to Ethereum built to be the entry door for liquidity.
S is the network’s native crypto-asset and replaced FTM one for one: whoever held one FTM converted it into one S. On Young Platform you can buy and sell the crypto-asset S on a spot basis.
Who develops Sonic and who governs it
The network is developed by Sonic Labs, heir to the Fantom Foundation. The best-known name tied to the project is Andre Cronje, the developer who created Yearn Finance and who led Sonic’s technical work, including the design of the bridge. But 2026 was the year of the changing of the guard: on 20 June 2026 Cronje, Michael Kong, formerly chief executive of Fantom, and chairman David Richardson resigned from the board, and leadership passed to Matt Visser as chief executive. It was the second turnover in a few months, after the departure in February 2026 of the executive hired in September 2025 for the expansion into the United States.
Cronje clarified that he was neither a founder of the company nor responsible for the migration from FTM, the airdrop or the token’s issuance rules. He remains tied to the ecosystem through Flying Tulip, a decentralised exchange built on Sonic. Governance of network parameters goes through validators and those who stake S.
How the network works
Sonic produces blocks with finality in under a second and claims a laboratory capacity of hundreds of thousands of transactions per second, a number to be read as a theoretical limit, not real traffic. Two mechanisms set it apart. The first is the Sonic Gateway, the bridge with Ethereum, designed with a safety clause: if the bridge stopped working for an extended period, users could recover their funds directly on Ethereum. The second is Fee Monetization: up to 90% of the fees generated by an application go back to whoever developed it, instead of to validators, to attract developers to the network.
For those coming from Fantom, the old Opera network has stayed on in parallel. Its shutdown was scheduled for 30 June 2026; on 24 June the new leadership postponed it to at least the end of 2026, with the bridge between the two networks still funded.
2025 and 2026: from the race to the restructuring
Sonic’s first year was a rapid climb. The S token reached its all-time high in January 2025, a few weeks after launch; the value locked in the network’s applications passed 1.1 billion dollars in May 2025, driven by incentives and by an airdrop of 190.5 million S distributed in phases from July 2025. Then the descent: in June 2026 the value locked had fallen below 30 million dollars, and the token was trading around 97% below its high.
The new leadership responded with three decisions taken in the same week of June 2026: the board resignations, the postponement of Opera’s shutdown and the waiver of the annual issuance of 47.6 million S planned for 2026, with the stated aim of no longer increasing supply. Visser said he was not promising an instant turnaround, but operational discipline and transparency. It is a rebuilding phase, and should be read as such.
What the S token is for
S has four functions. It pays transaction fees. It is put into staking, by delegating it to a validator, to contribute to the network’s security and receive rewards that are variable and not guaranteed, with a two-week waiting period for withdrawal. It is needed to run a validator. And it grants the right to vote on governance.
On the supply side, the original design provided for an issuance of 47.6 million S a year for six years, intended to fund growth, with the unused part destroyed; validator rewards reallocated from Fantom’s budget; and the destruction of part of the airdrop for those who withdrew early. The 2026 issuance was skipped, as described above: future rules depend on the decisions of the new leadership and of governance.
What to consider before buying S
Beyond the volatility common to all crypto-assets, there are three specific elements. The first is execution: in 2026 the project changed its top management twice, lost its best-known name and reopened the calendar of the old network; the new team’s ability to attract applications and users is entirely to be proven. The second is demand: the value locked has fallen by more than 95% from its peak, and with it the use of the network that gives the token its meaning. The third is competition: Sonic competes with dozens of Ethereum-compatible networks, many of them larger and better funded. On the price side, S reached its all-time high in January 2025.
If you want to transfer S to an external wallet, always check the supported destination network in the app: S exists on the Sonic network and, through the bridge, on Ethereum, and sending on the wrong blockchain can result in the permanent loss of funds.
In summary
Sonic is the attempt to refound Fantom with a new network, a bridge with a safety clause and a model that pays developers with fees, and in 2026 it entered a rebuilding phase with new leadership and token issuance suspended. Understanding that the value of S depends on the return of applications and users, not on the technology itself, is the best way to decide whether and how to add it to your crypto-asset portfolio.
