Sophon sets Nov 25 withdrawal deadline ahead of Nov 30 mainnet shutdown
Sophon announced a November 25 deadline for users to withdraw assets before its Ethereum layer-2 mainnet shuts down permanently on November 30.
Why it matters
The shutdown highlights the economic challenges of operating standalone layer-2 networks and the operational risk to users who fail to withdraw assets before infrastructure is retired. It follows a pattern of consumer-focused chains winding down after failing to achieve sustainable traction.
Key facts

What happened
Sophon, a zero-knowledge-powered Ethereum layer-2 network focused on consumer applications, has set November 25, 2026 as the final deadline for users to withdraw SOPH, ETH, USDC, staking rewards, Guardian rewards, and farm assets before its mainnet shuts down on November 30. The project announced in June that maintaining a standalone blockchain was no longer cost-justified and it would shift focus to consumer finance and AI applications on Base. Binance migrated SOPH to Ethereum at a 1:1 ratio on August 4, while Upbit plans to end SOPH trading on November 16. The shutdown follows a similar announcement from Abstract, the Pudgy Penguins-affiliated layer-2, which plans to close on December 15.
