Quick answer: The Sophon shutdown is set for Nov. 30, 2026, and users must withdraw SOPH, ETH, USDC and other assets by Nov. 25, when key infrastructure starts going offline, the team said on X on Oct. 19, 2026. Assets left behind may become permanently inaccessible. SOPH fell about 14% in 24 hours, per CoinGecko.
The Sophon shutdown now has a firm date. On Oct. 19, 2026, at 18:43 UTC, Sophon said on X that it plans to switch off its mainnet on Nov. 30, 2026, and asked users to withdraw everything well before then.
Anyone still holding tokens on the chain has about five weeks to act. After the deadline, Sophon warns, leftover assets “risk becoming permanently inaccessible.”
What is the Sophon shutdown?
Sophon launched as a zero-knowledge Ethereum layer-2 built for consumer apps such as games and AI tools. On June 25, 2026, the team said it would wind the chain down and build apps on Base instead.
However, running its own chain had become too costly. Co-founder Seb told The Block that the network cost about $3.4 million a year, and closing it cuts annual spending by roughly $3 million. New deposits into Sophon have been disabled since that date.
Meanwhile, the project was well funded. Cointelegraph noted it raised $60 million through a 2024 node sale plus a separate $10 million round.
Why is Nov. 25 the real deadline?
In fact, Sophon was blunt about this. “Nov 25 is the date to act, not Nov 30,” the team wrote. Key infrastructure and related websites will begin shutting down after Nov. 25. As a result, the claim tools may not work in the final days.
How do you withdraw assets before the Sophon shutdown?
Sophon’s migration guide lays out a short process:
- Open the official claim portal. Go to claim.sophon.com, the single portal Sophon names for the whole transition.
- Claim rewards first. Collect any unlocked staking or Guardian rewards shown there.
- Withdraw liquid tokens. Move SOPH, ETH, USDC and any other tokens off Sophon through the canonical route to Ethereum.
- Empty old farm positions. If you used Sophon Farm, withdraw those assets at farm.sophon.xyz, as Sophon asked on X.
On the other hand, you do not need to touch Guardian NFTs, vSOPH or staked SOPH. Per the guide, these positions are being moved to Ethereum for their holders automatically. Also note that LayerZero stopped bridging to and from Sophon Chain on June 25, so the canonical route is the main exit.
Does the Sophon shutdown mean swapping SOPH?
No. SOPH is native to Ethereum, and the token on Sophon Chain is only a bridged copy, so there is no swap or new token. Therefore, any site offering a “SOPH migration” is a red flag. Sophon told users to rely only on official links, and fake portals often surface during shutdowns, as our report on a Safe wallet scam ad showed.
How much money is still on Sophon Chain?
Very little, which suggests most users already left. Sophon’s total value locked peaked near $20.1 million on May 30, 2025, per DefiLlama. It was about $303,000 on June 25, 2026, and only about $15,000 on Oct. 20, 2026.
Still, small balances matter to the people who hold them. For example, unclaimed rewards are easy to forget until a chain goes dark.
What does the Sophon shutdown mean for the SOPH price?
SOPH traded near $0.00181 at about 07:00 UTC on Oct. 20, 2026, per CoinGecko. That is down 14.1% in 24 hours and 46.5% over seven days. Its market cap is about $9.1 million, roughly 98% below the all-time high of $0.1108 set on May 28, 2025.
Instead of gas fees, the token now relies on a new model. The team plans to use revenue from its Base apps, starting with the payments game Pyre, to buy back and burn SOPH, per The Block. SOPH held on Ethereum or on exchanges is not on Sophon Chain itself, but check your exchange’s notices about network support.
Is this part of a bigger layer-2 trend?
It looks that way. The Abstract shutdown set a Dec. 15 bridge-out date, and Blur is closing its frontend on Nov. 12. In short, smaller chains are struggling to justify their costs while activity concentrates on Ethereum and big rollups like Base. That keeps the Ethereum price central to the whole layer-2 story.
Sophon Shutdown FAQ
When will Sophon shut down?
Sophon plans to shut down its mainnet on Nov. 30, 2026, the team said on X on Oct. 19, 2026. Key infrastructure and websites will start going offline after Nov. 25.
What is the Sophon withdrawal deadline?
The deadline is Nov. 25, 2026. Sophon says assets left on the chain after that date risk becoming permanently inaccessible, so users should withdraw through claim.sophon.com well before then.
Will I lose my SOPH tokens?
Not if you act in time. SOPH is native to Ethereum, so bridged SOPH on Sophon Chain should be withdrawn to Ethereum by Nov. 25. SOPH already on Ethereum or held on an exchange is not on Sophon Chain.
Do Guardian NFT holders need to do anything?
Guardian NFTs, vSOPH and staked SOPH are being moved to Ethereum automatically, per Sophon’s migration guide. Holders should still check claim.sophon.com for unclaimed rewards.
