Sophon has established a November 25 deadline for users to withdraw assets from its Ethereum layer-2 blockchain ahead of the network's planned mainnet shutdown. The team announced that key infrastructure and related websites will begin closing on this date, warning that any assets remaining on Sophon Chain after the cutoff risk becoming permanently inaccessible.
Users are required to withdraw specific tokens, including Sophon (SOPH), Ether (ETH), USDC (USDC), and other supported assets, while also claiming any outstanding staking or Guardian rewards before the deadline. This operational wind-down follows a June announcement in which Sophon stated it would abandon its standalone zero-knowledge-powered layer-2 network, originally focused on consumer applications such as gaming, entertainment, and AI. At that time, developers cited the high costs of maintaining a separate blockchain as no longer justified by its benefits, opting instead to pivot operations toward Base to focus on consumer finance and AI applications.
The decision mirrors recent developments in the sector involving Abstract, another consumer-focused Ethereum layer-2 network developed by Igloo, the parent company of Pudgy Penguins. Abstract announced on October 6 that it would close on December 15 after sustaining tens of millions of dollars in losses supporting the network. Sophon previously raised $60 million through a node sale in 2024, following an earlier $10 million funding round.
Sophon’s migration from a dedicated layer-2 architecture to the Base ecosystem highlights the intensifying economic pressure on smaller blockchain networks attempting to compete with established scaling solutions. By citing maintenance costs as unjustified relative to benefits, the project acknowledges that sustaining independent infrastructure requires significant capital and user activity levels that many emerging networks fail to achieve. This strategic retreat underscores a broader consolidation trend where projects prioritize leveraging existing liquidity and security models over building proprietary chains.
The parallel shutdowns of Sophon and Abstract suggest a structural vulnerability within the consumer-focused layer-2 segment, particularly for networks backed by NFT communities or niche gaming applications. While these projects initially attracted substantial venture capital, the inability to generate sustainable revenue streams against rising operational expenses forces abrupt pivots or closures. Investors and users must now navigate the risks associated with asset accessibility during these transitions, as the technical complexity of migrating state data and ensuring secure withdrawals increases the potential for user error or permanent loss if deadlines are missed.
