SKN | Sophon Sets November 25 Withdrawal Deadline Ahead of Mainnet Shutdown

Key Points

• Sophon has set November 25 as the deadline for users to withdraw assets before it begins shutting down key infrastructure and related websites, warning that remaining assets could become permanently inaccessible.
• The Ethereum layer-2 project is asking users to withdraw SOPH, ETH, USDC and other assets, as well as claim outstanding staking and Guardian rewards.
• The shutdown follows a strategic shift announced in June, when Sophon’s developers said the cost of maintaining a standalone blockchain no longer justified its benefits and outlined plans to focus on consumer finance and AI applications on Base.

Sophon is preparing to shut down its Ethereum layer-2 network, giving users until November 25 to withdraw their assets before key infrastructure and related websites begin closing. The decision reflects a broader reassessment of the economics of operating independent blockchain networks as projects seek more sustainable platforms for consumer applications.

In an announcement on Monday, Sophon said it would begin shutting down key infrastructure and associated websites on November 25. The team warned that assets remaining on Sophon Chain after the deadline risk becoming permanently inaccessible.

Users have been instructed to withdraw their Sophon (SOPH), Ether (ETH), USD Coin (USDC) and other assets held on the network. The team also urged users to claim any outstanding staking or Guardian rewards before the shutdown begins.

Sophon Shifts Away From Its Standalone Blockchain

Sophon launched as a zero-knowledge-powered Ethereum layer-2 network focused on consumer applications, including gaming, entertainment and artificial intelligence.

However, in June, its developers announced plans to discontinue the standalone blockchain strategy. They said the costs of maintaining an independent network no longer justified the benefits, prompting a shift toward consumer finance and AI applications on Base.

The decision highlights a challenge facing blockchain projects that operate their own infrastructure. Maintaining a network requires ongoing technical development, security measures and operational resources, while attracting enough users and applications to justify those expenses can be difficult.

By moving its focus to Base, Sophon is seeking to pursue its consumer-oriented strategy without continuing to support its existing standalone chain. The announcement does not provide a detailed timetable for the transition of individual applications or specify how every existing service will be affected.

For users, the immediate priority is the withdrawal deadline rather than the project’s longer-term product strategy.

Users Face a Deadline to Secure Remaining Assets

Sophon’s warning that assets could become permanently inaccessible makes the November 25 deadline a significant operational milestone for holders of tokens and other assets on the network.

Users should identify all assets held on Sophon Chain, including tokens and any outstanding staking or Guardian rewards, and follow the project’s official withdrawal instructions. They should also verify the destination network and address before initiating transfers.

The announcement does not specify whether recovery options will remain available after infrastructure shutdown begins. Users should therefore avoid assuming that assets left on the network can be retrieved later.

The closure also illustrates why holding assets on a blockchain can involve risks beyond market volatility. Even when a token retains market value, access may become difficult if the infrastructure required to interact with it is discontinued.

Abstract Announces a Separate Layer-2 Shutdown

Sophon’s planned closure follows a similar announcement from Abstract, a consumer-focused Ethereum layer-2 network developed by Igloo, the parent company of Pudgy Penguins.

On October 6, Abstract announced plans to close on December 15. The report attributed the decision to the substantial financial burden Igloo faced in supporting the network, which had reportedly cost tens of millions of dollars.

The two announcements point to financial sustainability as a concern for consumer-focused blockchain infrastructure. Projects must balance the cost of maintaining their networks against user activity, application demand and their ability to generate sufficient revenue or secure continued funding.

However, Sophon and Abstract are separate projects, and the available information does not establish that their shutdown decisions share the same underlying causes beyond the reported financial considerations.

Sophon reportedly raised $60 million through a node sale in 2024, following an earlier $10 million funding round. The planned shutdown therefore marks a significant change in direction for a project that previously secured substantial funding to support its network.

Outlook

Sophon’s November 25 deadline places the immediate responsibility on users to withdraw their assets and claim outstanding rewards before infrastructure shutdown begins. Its shift toward Base reflects a reassessment of the costs and benefits of operating a standalone blockchain, while the separate Abstract closure highlights similar pressures across consumer-focused layer-2 projects. The longer-term outcome will depend on how effectively Sophon transitions its consumer finance and AI ambitions to Base and how users navigate the closure of its existing network.
