On October 20, 2026, the official announcement from the entertainment modular blockchain network Sophon revealed the mainnet retirement schedule, planning to officially cease all mainnet operations on November 30, 2026.
The official has clearly set the deadline for withdrawing on-chain assets at November 25, 2026. As key infrastructure and interaction interfaces are gradually shut down, any remaining assets face a real risk of irreversible loss; holders are urgently urged to initiate asset withdrawals and cross-chain migration immediately.
Premature shutdown of critical infrastructure triggers hard liquidation countdown for assets.
As a general-purpose entertainment application chain originally built on the ZKsync superchain technology stack, Sophon attracted significant market attention during its node sale and fundraising phases. Amid increasing competition in the multi-chain ecosystem and the consolidation of liquidity, the team ultimately decided to shut down its mainnet.
According to the official schedule, the most critical issue for token holders to be aware of is the gap between the "Mainnet Final Shutdown Date" and the "Asset Withdrawal Deadline." Although the on-chain final shutdown is set for November 30, core infrastructure—including cross-chain bridge relays, RPC node resolution, the official frontend interaction website, and the foundational verification network—will be gradually decommissioned starting November 25.
This means users must never treat November 30 as a safe deadline. Once the critical point of November 25 arrives, regular users will lose access to the user-friendly web interface; if the node relays are fully cut off, assets remaining in the smart contract—though still reflected on the ledger—will be technically inaccessible forever due to the absence of cross-chain settlement relays.
Comprehensive Asset Withdrawal Guide and Node Reward Settlement
With less than a month remaining in the withdrawal window, community members holding relevant assets need to conduct a comprehensive review and step-by-step management of their personal accounts.
This withdrawal covers the full spectrum of assets within the Sophon network ecosystem. In addition to basic liquidity such as native tokens SOPH, Ethereum ETH, and stablecoins like USDC held in wallets, users who participated early in Sophon Farm liquidity mining must manually exit and unlock their shares via the corresponding partner platform page.
Meanwhile, users who previously purchased and operated Guardian guardian nodes must log in to the node control panel before the deadline to withdraw all unclaimed node operation rewards to an external mainnet wallet.
The official team has issued a special security alert: during the ecosystem migration and liquidation period, phishing sites and counterfeit airdrop websites are highly active. Users must strictly verify official domains and avoid clicking on any external private messages or counterfeit migration guidance links.
Reflections on the Final State of Liquidity After the Modular Blockchain Hype Fades
The official shutdown of the Sophon mainnet objectively reflects the harsh reality faced after the recent wave of modular blockchain scaling receded.
During the boom period of proprietary application chains, many projects that attracted capital accumulation through public node presales and expectations of ecosystem token airdrops have since faced severe challenges of insufficient real user activity and lack of fee-based revenue generation as they entered the stable mainnet operation phase.
Once early token incentives are exhausted, underlying networks lacking an internal business闭环 often struggle to cover the high costs of data availability and full node maintenance.
Sophon proactively defined its liquidation timeline and publicly disclosed its exit roadmap before assets were fully locked, avoiding the risk of an abrupt, unannounced departure—but it has also sounded an alarm for the entire industry: experiments that blindly pursue customized chain architectures while neglecting real liquidity accumulation will ultimately reach their end in the cycle of capital evolution.
