Sophon has told users to remove assets from its blockchain by Nov. 25, 2026, ahead of a planned mainnet shutdown on Nov. 30. The project said holders should withdraw SOPH, ETH, USDC and any other assets still on the network, along with unpaid staking rewards, Guardian rewards and funds in Sophon Farm.

The team emphasized that Nov. 25 is the practical cutoff for users, not the final shutdown date. Sophon warned that parts of its web infrastructure and related services may begin going offline after that date, meaning access to withdrawal tools could be disrupted before the chain stops operating entirely.

Users told to act before services begin closing

In its latest notice, Sophon directed users with liquid balances to its official claims portal, where they can withdraw eligible assets and collect outstanding rewards. For assets held in Sophon Farm, the project said withdrawals must be completed through the farming platform.

The five-day gap between the withdrawal deadline and the chain’s final shutdown is central to the warning. Sophon did not guarantee that withdrawals would remain available through Nov. 30 and said key websites and network infrastructure could start shutting down after Nov. 25. The project also urged users to use only official links and to be alert for fraudulent migration or claims sites designed to capture wallet approvals or funds.

Shutdown plan was first announced in June

Sophon began winding down its standalone blockchain earlier this year. In a June 25 announcement, the project said it had decided that the expense of running its own network was no longer justified by the benefits it provided.

Founder and CEO Seb said the team had revisited the purpose of maintaining the chain and concluded that spending millions of dollars a year on infrastructure was not warranted. Sophon said it would instead concentrate on building consumer finance and artificial intelligence applications on Base, the Ethereum layer-2 network developed by Coinbase.

What the change means for SOPH

The shutdown affects the original role of Sophon’s native token. Under the project’s transition plan, SOPH’s previous functions for network fees and staking on the standalone chain are being phased out as that chain is retired.

Sophon has said it intends to replace those mechanics with token buybacks and burns funded by revenue from its consumer products. The company has named Pyre, its finance application, as one possible revenue source for that approach. Earlier in its development, Sophon raised $60 million through a 2024 node sale after a separate $10 million funding round, and had positioned its zero-knowledge-based network around consumer uses such as gaming and entertainment.

Exchange migration happened before the latest notice

Parts of the market had already started moving away from the Sophon mainnet before the October withdrawal warning. On July 28, Binance said it would stop supporting SOPH deposits and withdrawals on the Sophon network from Aug. 4 and would migrate the token to Ethereum’s ERC-20 standard at a 1:1 ratio.

Binance said at the time that spot, margin and futures trading, as well as Binance Earn services, would not be affected by the network change. That distinction indicates the closure of Sophon’s blockchain does not automatically mean the SOPH token itself disappears. crypto.news had also previously reported closer monitoring of SOPH by Binance, while Upbit placed the token under investment caution and South Korean exchanges updated the networks they support for deposits and withdrawals.

Next confirmed step is the Nov. 25 asset deadline

For now, Sophon has not announced any extension beyond Nov. 25 for users who still hold assets on the retiring chain. Its Oct. 19 instructions cover liquid token balances, unpaid staking and Guardian rewards, and assets remaining in Sophon Farm.

The confirmed timeline is therefore straightforward: users are expected to complete withdrawals by Nov. 25, while the blockchain itself is scheduled to shut down on Nov. 30. Sophon’s stated direction after that is to continue development on Base rather than maintain its own mainnet.
