Today marks an important milestone for Zircuit. We’re excited to introduce Zircuit Finance, a major evolution of the project that reflects where our ecosystem has grown, and where we see the greatest opportunity ahead.
From Chain-First to Application-First
Zircuit began with a chain-first vision: a technically advanced L2 centered around sequencer-level security (SLS), designed to protect users at the settlement layer. We built that system, shipped it to production, and proved it under real-world conditions.
Along the way, we paid close attention not just to how the system performed, but to how users actually engaged with Zircuit.
Over time, a clear pattern emerged. The moments of strongest adoption and excitement came from applications and ecosystem initiatives, not from the chain itself. Programs like the Liquidity Hub, which peaked at $3.6B in TVL, and yield-driven launches consistently attracted users and capital. The signal was clear: application-level opportunities are what resonate most.
Introducing Zircuit Finance
Those observations shaped our next step.
Zircuit Finance is designed as an omnichain DeFi application built for onchain users in 2026. It can onboard capital from multiple networks and deploy it across a growing set of yield strategies, without relying on a dedicated settlement layer.
At launch, Zircuit Finance provides access to 8.6% APR on stablecoins and supports capital from major ecosystems, including Ethereum and Base. Over time, we plan to expand supported assets, strategies, and integrations, making Zircuit Finance a base layer for yield across the onchain economy.
Proven Security Foundations
Zircuit Finance is built on the same security-first principles that defined Zircuit from the beginning. SLS performed exactly as intended. It introduced sequencer-level security (SLS) as a production system and operated reliably in real-world conditions. SLS prevented millions of dollars in potential losses and protected users from phishing attacks. The chain operated without any loss of user funds, validating both its design and execution. Importantly, the system also demonstrated resilience against exploit patterns that later affected the broader industry, including the Balancer exploit in November 2025, which SLS would have flagged and blocked at the sequencer level.
Throughout the lifetime of the chain, no user assets were ever lost. That work matters, and it continues to inform how security is applied to Zircuit Finance today.
What this means for the L2
Zircuit is transitioning toward an application-first future. The L2 network will transition from the true zero-knowledge rollup it is today into a rollup with stronger trust assumptions, where state outputs are posted without validity proofs. The chain will remain operational in a best-effort availability mode until further notice, and the token will continue along with Zircuit Finance.
Applications on the following URLs will also remain operational, but without official support, and will be only maintained on a best effort basis:
During this period, users are encouraged to gradually migrate capital into Zircuit Finance, use it as a bridge across settlement layers, and withdraw assets from the L2 network at their own pace. The sequencer will no longer perform active SLS analyses for the L2 itself. However, the SLS monitoring infrastructure will remain fully operational and will continue to be actively used to protect deposits within Zircuit Finance.
Looking further ahead, the L2 network may either transition into an optimistic rollup configuration or move toward a definitive deprecation. Any such change will be communicated well in advance, including clear guidance ahead of any escape hatch activation. Maintaining asset safety remains our top priority.
Looking Ahead
Zircuit Finance will operate as an omnichain DeFi application, free from the overhead of maintaining a standalone L2.
This focus allows us to move faster on what really matters most to users: expanding yield opportunities, strengthening security, and supporting capital across chains where onchain activity already lives.
We’re proud of the chain we built. We’re even more excited about the ecosystem we’re building next.
