Sophon Sets November Deadline to Close Its Blockchain as Crypto's Layer 2 Economics Face Scrutiny

Sophon has set November 25 as the deadline for users to withdraw assets from its blockchain, five days before the network's planned final shutdown on November 30. The decision completes a strategic shift announced in June: instead of operating its own Ethereum Layer 2 network, the company will focus on consumer finance and AI applications built on Base. The project says assets left on Sophon Chain after the withdrawal deadline could become permanently inaccessible.

The closure is more than a technical migration. It raises a commercial question facing blockchain developers: when does maintaining a dedicated network cost more than the strategic value it creates?

Sophon is not the only project reconsidering that balance. Abstract, another consumer-focused Ethereum Layer 2, announced in October that it would shut down on December 15 after its backer, Igloo, reported losses of tens of millions of dollars from operating the network. The decisions are not identical, but together they show that launching a blockchain and sustaining a viable business around it are separate challenges.

Sophon's shutdown has two separate deadlines

Sophon's October announcement distinguishes between the date users should complete withdrawals and the date the network is scheduled to close.

The earlier deadline matters because key infrastructure and related websites are expected to begin closing after November 25. The November 30 date should not be interpreted as a guarantee that all withdrawal routes will remain available until then.

The scope of the announcement also extends beyond SOPH tokens. Sophon has identified ETH, USDC, outstanding staking and Guardian rewards, and assets held in Sophon Farm as categories requiring attention. These assets may involve different withdrawal or claim mechanisms.

Exchange support is a separate issue from network operation. Binance moved its supported SOPH transfers to Ethereum in August at a 1:1 migration ratio, while Upbit has a separate trading schedule. Neither exchange timetable establishes whether other assets or positions remaining on Sophon mainnet can be moved after the project's own deadline.

Why Sophon is leaving its own network

Sophon's decision follows a reassessment of the cost of maintaining a dedicated blockchain relative to the activity it generates.

In June, the company said its infrastructure cost approximately $3.4 million annually and estimated that shutting down the chain could reduce its annual spending by around $3 million. These figures were reported by The Block based on statements from the project's leadership. They are company estimates, not independently audited savings or evidence of the new business's profitability.

The project had raised $60 million in 2024 to build its network, according to Sophon's own announcement and reporting by Chainwire. That funding enabled the development of infrastructure, but it did not remove the need to attract sustained activity capable of justifying ongoing expenditure.

The Defiant reported in June that Sophon had fewer than 200 daily active users and generated approximately $30 in daily network fees at the time of its shutdown announcement. Those figures provide a snapshot of the gap between the project's infrastructure investment and the direct economic activity reported for its chain. They should be understood as estimates from that reporting period, not current measurements or a complete assessment of Sophon's products and financial position.

The commercial problem is straightforward. A network incurs costs for infrastructure, development, maintenance, security and ecosystem support. If user demand and revenue do not justify those costs, a project must find another source of funding, reduce its operating model or reconsider whether running the network itself remains necessary.

From blockchain infrastructure to consumer applications

Sophon's new strategy centres on building consumer-facing products on Base rather than maintaining a separate chain. Its announced product direction includes Pyre, a payments application, alongside other planned consumer finance and AI products.

The move changes where the business expects to create value. Under the previous model, SOPH served as the network's gas and staking asset. With the chain being decommissioned, that original source of utility is ending.

Sophon has said that revenue generated by its applications will support SOPH buybacks and burns. Under this model, the token's longer-term economic proposition would depend more directly on the performance of the company's products than on transactions conducted on its own network.

That is a material change, not simply a technical migration.

The existence of a product portfolio does not establish how much revenue it will generate, how much will remain after operating expenses or what proportion will be allocated to token purchases. Those outcomes require evidence from commercial performance and the company's eventual financial disclosures.

The strategy therefore introduces a different set of questions. Can Sophon attract customers to its applications? Can those products generate recurring revenue? Will the revenue be sufficient to support development and operations while funding the proposed buyback programme? The shutdown itself does not answer these questions.

Abstract's decision points to a wider commercial problem

Sophon's announcement comes amid another significant change in the consumer Layer 2 sector.

On October 6, Abstract announced plans to close its Ethereum Layer 2 network on December 15. According to The Block, Abstract had onboarded more than 400,000 users and deployed over 144 applications, but its backer cited stagnant growth, thin liquidity, a restricted DeFi ecosystem and limited institutional adoption. Igloo's CEO said the company had lost tens of millions of dollars supporting the network.

Abstract's situation differs from Sophon's in important ways. Its reported user base and application ecosystem were larger, and its backer decided against launching a token to finance continued operation. Nevertheless, both decisions challenge the assumption that a dedicated consumer blockchain is automatically a sustainable business.

User numbers alone do not establish economic viability. A network can attract wallets and developers without generating enough recurring revenue to cover its costs. Incentives may create activity while they are available, but the underlying question is whether users continue to transact when the subsidies or promotional programmes are reduced.

Likewise, the number of applications deployed does not necessarily reflect how many people use those applications regularly, how much liquidity they retain or whether the ecosystem supports businesses beyond its initial funding period.

For crypto projects, these distinctions matter when evaluating the strength of a network. Adoption metrics, transaction counts, total value locked, fee revenue and operating expenses measure different things. None should be used as a substitute for the others.

The strategic question: own the infrastructure or build on established networks?

Sophon's move to Base reflects a choice between maintaining proprietary infrastructure and using an established network to distribute applications.

Operating a dedicated chain can offer control over the technical environment, network design, transaction economics and ecosystem strategy. It can also create additional responsibilities: maintaining infrastructure, attracting developers, building liquidity and convincing users that the network offers a reason to exist alongside established alternatives.

Building on an existing network can reduce the need to operate every layer of infrastructure independently. It may also provide access to an existing user base, established tooling and a broader application ecosystem. However, this approach introduces dependencies on another network's technical roadmap, fee structure and operational decisions.

Neither model is inherently superior. The appropriate structure depends on what a project needs to differentiate, how much activity it can attract and whether the benefits of owning infrastructure justify its full cost.

Sophon's decision suggests that its leadership no longer considers operating its own chain the best use of resources. Its new approach puts greater emphasis on the applications themselves. Whether that change produces a stronger business remains to be demonstrated.

What the shutdown means for SOPH's economic model

The token's transition deserves separate attention because a blockchain can close while a token continues to exist and trade on other networks.

Binance's migration of SOPH to Ethereum illustrates this distinction. The exchange's announcement specified a 1:1 migration and stated that its spot, margin, futures and Earn services would not be affected by the network change. That does not mean every SOPH holder has completed a migration, nor does it guarantee future exchange support.

More importantly, continued token availability does not preserve the economic role that the token previously held on Sophon mainnet. When the network closes, its original gas demand ends with it. The proposed buyback-and-burn model would need to establish a different connection between the token and the company's business.

For that model to become measurable, market participants would need evidence of product revenue, the amount allocated to buybacks, the timing and execution of purchases, and the relationship between these transactions and the token's circulating supply.

Sophon has described its intended model, but future product revenue and the scale of any resulting buybacks cannot be inferred from the chain's previous transaction activity or the company's estimated infrastructure savings.

The distinction is important: a reduction in operating costs can extend a company's runway, but it does not automatically create revenue. Likewise, a token burn can reduce supply, but its economic significance depends on the scale and funding of the purchases and on demand for the token.

A test of whether the product layer can support the business

Sophon's shutdown is a concrete operational event. Its transition to a consumer application studio is a business strategy whose results will emerge over time.

The next evidence to watch is not simply whether the mainnet closes on schedule. It is whether the company can demonstrate sustained product usage, recurring revenue and a transparent relationship between commercial performance and SOPH's proposed buyback mechanism.

The migration also tests the project's ability to manage an orderly wind-down. The November 25 deadline, the separate routes for different asset categories and the differing exchange schedules create operational dependencies that cannot be resolved by the token continuing to trade elsewhere.

The broader lesson for the Layer 2 sector is not that dedicated blockchains are no longer viable. It is that infrastructure must justify its cost through the activity and value it enables. A network can be technically functional, well-funded and supported by an application ecosystem without becoming a sustainable business.

Sophon has decided to redirect its resources from operating a chain to building products on another network. Abstract has reached a different shutdown decision under its own commercial circumstances. Both cases show that the long-term viability of a blockchain depends on more than its launch, funding or headline adoption figures.

For Sophon, November will mark the end of its dedicated network. Whether its next phase proves more commercially sustainable will depend on what the business builds—and what those products actually earn.
