Fantom is positioning its Sonic upgrade as a defining step in its next phase of growth, combining major infrastructure changes with ecosystem incentives in an effort to regain traction after a difficult stretch marked by market turbulence and bridge-related setbacks. Based on the source material, Sonic is designed to improve execution speed, reduce node storage requirements, and make the network more attractive for developers building decentralized applications.
A performance-focused overhaul
The headline goal of the Sonic upgrade is ambitious: Fantom expects the new architecture to support more than 2,000 transactions per second with one-second finality. For a network that originally built its reputation on fast and inexpensive transactions, the upgrade is being framed as a way to restore and extend that edge.
At the center of this effort is the Fantom Virtual Machine (FVM), which is set to replace the older Ethereum Virtual Machine model currently used by the network. According to the original article, FVM will convert legacy EVM bytecode into a new virtual machine format, support “super instructions,” and optimize bundles of commonly recurring transaction types. The expected outcome is significantly more efficient smart contract execution for validators and an estimated 65x speed improvement over the previous EVM-based mechanics.
If those gains are achieved in production, Fantom would be trying to reposition itself among high-throughput chains that compete on user experience, execution speed, and cost efficiency. In practical terms, faster execution and quicker finality could support more responsive DeFi applications, smoother user interactions, and potentially lower friction for builders deploying new products on the network.
Storage reduction and validator efficiency
Sonic is not only about transaction speed. The upgrade also targets one of the less visible but highly important constraints in blockchain infrastructure: storage. The source states that Fantom expects storage requirements to fall by around 90% through a new database technology called Carmen.
Carmen uses a flat storage mechanism instead of a tree-like structure, which is meant to simplify data retrieval and allow live pruning. In this context, live pruning refers to the ability of validators to discard historical data that is no longer needed without disrupting network operations. This can free up substantial disk space and lower the hardware burden associated with participating in the network.
The scale of that reduction is notable. The source gives the example of archive node storage dropping from roughly 11TB to below 1TB. For infrastructure providers, validators, and technically sophisticated community operators, that kind of reduction could make network participation more accessible and cost-effective. It may also help Fantom sustain higher throughput without placing excessive operational demands on the entities that secure and maintain the chain.
FTM to become S on a 1:1 basis
One of the most important changes for token holders is the planned asset migration tied to the launch of Sonic. At the time the new Sonic network replaces the current Fantom Opera network, the native token FTM is expected to become S, with redemption available on a 1:1 basis.
That means the upgrade is not being presented merely as a backend performance improvement. It also includes a rebranding and token transition event that could reshape how the market views the chain. In crypto, token identity often plays a major role in visibility and narrative momentum, so the switch from FTM to S may be intended to signal a clean break from the network’s older chapter and align the asset with Fantom’s next-generation infrastructure.
The article also notes that Sonic-related testing environments have already been made available. A closed testnet showcases the network’s technical capability, while a builders testnet gives developers a space to begin experimenting with dApp deployment on the new system. That is relevant because upgrades of this scale require not just protocol readiness but ecosystem readiness as well. Developers need time to test, adapt, and prepare applications before a full transition can happen smoothly.
Developer incentives as part of the strategy
Fantom is pairing its technical roadmap with incentive mechanisms designed to stimulate on-chain activity and reward builders. The largest of these, according to the source, is the Gas Monetization Program.
Under this framework, qualifying dApps can receive 15% of the gas fees they generate for bringing users onto the network. The article describes this as a model similar in spirit to revenue sharing systems common in Web2 platforms, where creators are rewarded for audience activity. To qualify, a dApp must have been live on mainnet for more than one month, generate more than 15,000 transactions per contract, and maintain an active multisig wallet address.
The source explains that this program was made possible by lowering the transaction burn rate of the FTM token from 20% to 5% and redirecting the difference toward dApp incentives. It also notes that fees from dApps that do not meet the qualification requirements will still contribute to a distribution pool for the top 12 dApps on a tiered quarterly basis.
For Fantom, this is a meaningful strategic choice. Rather than relying solely on grants or short-term liquidity campaigns, it attempts to align application success with protocol-level fee generation. Whether that proves durable will depend on the scale of user activity and the quality of applications that choose to build on Sonic after launch.
USDC.e and the push for better liquidity access
Stablecoin infrastructure is another component of Fantom’s rebuild effort. The article states that on April 5, 2024, Fantom launched its canonical stablecoin USDC.e, backed by Circle and Wormhole. This asset is bridged from native USDC and may later be upgraded to native USDC.
That matters because smooth stablecoin access often plays a central role in DeFi participation. A bridged version of USDC can make it easier for users to move capital from other ecosystems into Fantom, reducing friction for traders, liquidity providers, and protocol users. The source further notes that the Fantom Foundation anticipated the future move to native USDC and supported additional liquidity for USDC.e trading pairs on Beethoven X and Equalizer Exchange.
Liquidity depth, onboarding convenience, and trusted stablecoin rails can all influence whether a chain becomes easy to use in practice. Fantom appears to recognize that infrastructure alone is not enough; users also need familiar assets and reliable transfer pathways if ecosystem growth is to accelerate.
The comeback narrative and the weight of history
The broader significance of Sonic becomes clearer when viewed against Fantom’s history. Fantom emerged in 2018 as a layer-1 blockchain emphasizing speed and low fees. It later partnered with Binance, launched the EVM-compatible Fantom Opera network, and became a major destination for DeFi activity during the 2021 bull market.
According to the article, Fantom eventually rose to become the second-largest chain for DeFi activity, with total value locked peaking at around $8 billion in March 2022. Its rise was associated with a combination of community-driven applications and the influence of Andre Cronje, one of DeFi’s best-known builders, whose work included Yearn Finance and Solidly, along with the now widely adopted Ve(3,3) design model.
But the chain also suffered a steep reversal. The broader crypto bear market hit Fantom hard, and the source describes the ecosystem as particularly exposed to leverage, extreme yields, and unsustainable tokenomics. At the bottom, FTM was down roughly 95% from its 2021 all-time high. Sentiment worsened further when Andre Cronje’s partner, Anton Nell, announced in March 2022 that both were stepping away from contributing to DeFi and crypto.
Another major blow came in July 2023, when approximately $102 million was reportedly withdrawn from Multichain’s Fantom bridge. The source breaks that figure down into 7,214 WETH worth about $13.6 million, 1,024 WBTC worth roughly $31 million, and $58 million USDC. As Multichain was one of the largest bridges in crypto at the time, the incident damaged confidence significantly.
The article also mentions a later legal development: in January, the Fantom Foundation was awarded a default judgment related to the recovery of lost Multichain funds after bringing action against the Multichain Foundation for breach of contract and fraudulent misrepresentation. While the source does not provide a final recovery outcome, it portrays the judgment as an important positive signal for Fantom’s long-term rebuilding effort.
Tokenomics and treasury strength
The original material also discusses FTM’s tokenomics as a factor in the Fantom thesis. It states that around 2.8 billion of 3.175 billion tokens were already in circulation, or roughly 88%, suggesting relatively limited future dilution compared with many newer tokens. Although unlocks continue through 2028, annual inflation is described as minimal at around 2%.
Another point emphasized in the article is the size of the Fantom Foundation treasury. Citing a November 2022 blog post from Andre Cronje, the source says the foundation held more than 450 million FTM, over $100 million in stablecoins, and another $50 million in non-crypto funds. The treasury was described as large enough to give the foundation an estimated 30-year runway.
For observers evaluating Sonic, that treasury position may be just as important as the raw technical specifications. A chain attempting a comeback needs resources to support infrastructure, liquidity, partnerships, ecosystem grants, and operational continuity. Fantom appears to have positioned itself with enough capital to keep investing in that process over a long horizon.
Why Sonic matters now
Sonic is ultimately a test of whether Fantom can translate engineering improvements into renewed relevance. The source presents the upgrade as more than a routine optimization. It is a system-wide reset touching execution, storage, token branding, developer revenue sharing, liquidity rails, and network accessibility.
If the technical claims hold up in production and the ecosystem successfully attracts new and returning developers, Fantom could regain some of the momentum it lost after 2022. But if the upgrade fails to create sustained application growth and user retention, improved throughput alone may not be enough in a crowded layer-1 and EVM ecosystem landscape.
For now, the story is clear: Fantom is trying to rebuild around speed, lower infrastructure costs, and stronger builder incentives. Sonic is the centerpiece of that effort, and its launch could become the clearest signal yet of whether the chain’s comeback narrative has real substance behind it.
