Sophon announced Thursday it will shut down its zkSync-based Layer 2 chain and pivot to "Soph+," a consumer product studio building only on Base, Coinbase's Layer 2 network.
The chain launched with $60 million raised through node sales but drew fewer than 200 daily active users. That user base never materialized into meaningful activity, even as node operators and token holders had staked capital on the project succeeding as a standalone chain.
The move amounts to a clean exit from L2 operations. Sophon will no longer run validator infrastructure, manage sequencer economics, or maintain its own rollup stack. Instead, the team is consolidating on Base, where it can ship consumer-facing products without managing chain overhead.
Node operators and token holders face uncertainty about what happens to their positions. The announcement did not specify migration mechanics, token swap terms, or a timeline for winding down the chain itself. Those details matter: investors who bought nodes expecting long-term validator rewards now have a dormant asset with no clear exit path.
Base itself has grown since Coinbase launched it in 2023. The network handles significant transaction volume and attracts developer attention. Sophon's bet is that riding an established, well-capitalized L2 removes execution risk around maintaining chain infrastructure and liquidity fragmentation—problems smaller chains face when users lack reason to stay.
The shift also signals how difficult it remains to build a standalone chain with user pull. Launching a rollup is cheap relative to a L1, but cheap is not the same as viable. You still need sequencer economics, validator incentives, bridge liquidity, and—hardest of all—a reason for users to use your chain instead of Ethereum, Polygon, Arbitrum, or one of the other established networks.
Sophon's retreat to Base is not unique. Other teams have wound down chains or migrated to existing L2s when user adoption faltered. The pattern suggests that the era of launching consumer L2s on spec may be passing. The capital and developer focus is moving toward consolidation on networks with real traction.
Sophon has not yet published detailed terms for existing stakeholders or a formal shutdown date.
