Sophon will shut down its network entirely on November 30 — assets must be withdrawn by November 25.

Withdraw assets (SOPH, ETH, USDC, and others) and claim rewards from staking and Guardian nodes by November 25. After that, infrastructure and websites will begin shutting down, and any remaining funds may become permanently inaccessible.

Sophon is a zkSync L2 whose shutdown was announced in June; the project is shifting to consumer apps on Base.
