Sophon has announced that it will permanently shut down its mainnet on November 30, giving users a narrow window to move their funds off the network. According to the announcement, anyone holding assets on the network must complete all withdrawals by November 25 — five days before the shutdown date. The announcement lays out a two-step process: a five-day withdrawal window, followed by a permanent cutoff of the live network.

Two Dates Users Need to Track

The project identified two separate dates that users need to keep in mind. November 25 is the last day Sophon says withdrawals should be completed, while November 30 is the day the mainnet goes offline for good. The distinction matters: the November 25 deadline is not the day the network stops operating, and users who wait until the shutdown date itself may find themselves unable to move their funds in time.

Sophon is a blockchain network with its own native token, SOPHON, which is listed on major crypto data trackers. Listing data, however, is separate from network operation: a token can remain visible on trackers while the chain it lives on is no longer processing transactions. The mainnet shutdown means the live network that processes real transactions and holds real assets will stop operating entirely.

Why Withdrawals Must Be Completed by November 25

The November 25 deadline sits five days ahead of the November 30 shutdown. That buffer exists so users have time to complete their transactions before the network becomes unavailable.

Cryptocurrency withdrawals are on-chain transactions, and on-chain transactions require a live network to confirm them. Once the mainnet goes offline on November 30, any funds still sitting in Sophon wallets or contracts on that network would have no active chain to process a withdrawal. This is also what separates a network shutdown from more common crypto events like an exchange delisting: a delisting changes where a token trades, while a mainnet shutdown removes the infrastructure that any transfer, on any venue, depends on.

Sophon has not publicly confirmed, in available sources, what happens to funds left on the network after the shutdown. Users should therefore consult the project's official communications directly for that detail. On the question of timing, however, the announcement leaves no room for ambiguity: November 25 is the stated action deadline.

A Rare Type of Shutdown

Shutdown announcements of this kind are relatively rare in the cryptocurrency industry. Most projects wind down gradually or migrate users to a new chain. In those scenarios, users typically have a continuing path for their assets on a successor network; in a hard mainnet shutdown with a firm withdrawal deadline, the withdrawal window itself is the exit path, and it requires faster action from anyone holding assets on the network. For context, other blockchain projects have navigated similar transitions — such as when JPM Coin moved dollar deposits onto's mainnet — highlighting how network-level decisions directly affect users holding assets on a chain.

Confirmed Timeline

Based on Sophon's announcement, the confirmed timeline is as follows:

• November 25: Last day to complete withdrawals from the Sophon network.
• November 30: The Sophon mainnet shuts down permanently.

Holders of SOPHON tokens or any other assets on the Sophon mainnet should treat November 25 as the date that requires action. Waiting until the shutdown date itself carries risk, since withdrawals depend on a network that will no longer be operational.

For full details on supported withdrawal methods, eligible assets, and any official guidance on unclaimed funds, users should check Sophon's official website and social channels directly. The announcement, as reported, does not cover those specifics, and the information could change before the deadline. Users relying on these dates should monitor official channels in case any element of the plan is revised.
