Coinbase-incubated Layer 2 network Base is entering a new phase of its development, moving toward a unified software architecture designed and operated internally.
The transition marks a gradual shift away from reliance on the OP Stack, the modular framework originally used to launch the chain, and reflects a broader strategy to gain deeper control over network infrastructure.
The move positions Base to accelerate upgrades, streamline operations, and tailor its technology to the specific needs of its ecosystem. While compatibility with the OP Stack will remain in the short term, the long-term roadmap outlines a transition toward a Base-native client and reduced dependency on external components.
Base Chain transitions from OP stack to its own unified software architecture
Launched in 2023 as an @Optimism chain, @base is shifting to its own tech stack to reduce dependence on external service providers and shorten the time to ship new upgrades.

Transition Toward A Unified Software Architecture
Base launched in 2023 as part of the Optimism ecosystem, leveraging the OP Stack to quickly deploy a scalable Layer 2 environment. The framework provided modular infrastructure components, enabling rapid development and interoperability with other networks built on the same stack.
The new initiative consolidates these components into a single repository optimized specifically for Base. By unifying its software stack, the network aims to simplify maintenance, improve performance, and create a more cohesive development environment.
This shift reflects a common trajectory among maturing blockchain networks. Early reliance on shared frameworks often accelerates launch timelines, but as ecosystems grow, projects frequently pursue custom infrastructure to better align with their operational goals and user demands.
Maintaining Compatibility While Preparing Independence
Despite the strategic pivot, Base will remain compatible with the OP Stack during the transition period. This approach ensures continuity for developers, node operators, and users while the new infrastructure is gradually introduced.
The network will also retain its Stage 1 rollup classification in the near term, signaling that its security model and operational structure remain largely unchanged for now. Maintaining compatibility reduces disruption and allows ecosystem participants to adapt incrementally rather than facing a sudden migration.
Over time, however, future upgrades will require node operators to transition to Base’s proprietary client, marking a clear step toward infrastructure independence. The phased approach underscores the network’s intent to balance innovation with stability.
Hard Fork Roadmap Signals Long-Term Vision
The shift in architecture comes ahead of several planned hard forks, which will introduce new technical capabilities and lay the groundwork for Base’s independent stack. Among the upcoming upgrades is V1 support for Fusaka, alongside changes to the network’s proof mechanisms.
Base plans to move away from traditional optimistic proofs toward Base-specific trusted execution environment (TEE) and zero-knowledge (ZK) systems. These technologies aim to enhance scalability, security, and verification efficiency, aligning the network with broader industry trends toward advanced proof frameworks.
Hard forks often represent pivotal moments in a blockchain’s lifecycle, enabling major protocol changes that would otherwise be impossible. In this case, they serve as stepping stones toward a more self-sufficient infrastructure model.
Simplifying The Sequencer And Network Operations
Another key objective of the transition is to streamline the network’s sequencer, the component responsible for ordering transactions before they are finalized on the blockchain. Simplifying this process can improve efficiency, reduce latency, and enhance the overall reliability of the network.
A more integrated software stack also makes it easier to coordinate upgrades and deploy new features. By reducing reliance on external service providers, Base can shorten development cycles and respond more quickly to emerging technical or market demands.
For node operators, the transition will require adopting the new Base client over the coming months to remain eligible for official upgrades. This migration represents a significant operational change but is intended to create a more cohesive and predictable infrastructure environment.
Market Reaction Highlights Ecosystem Interdependence
The announcement has already had ripple effects across the Layer 2 landscape. Following the news, the OP token, associated with the Optimism ecosystem, declined roughly 23% over a 24-hour period, reflecting how closely market sentiment can track developments in network partnerships and infrastructure alignment.
Such reactions underscore the interconnected nature of Layer 2 ecosystems, where technical decisions by one network can influence perceptions of others. As Base moves toward independence, it may reshape competitive dynamics among scaling solutions, particularly in terms of developer adoption and liquidity flows.
At the same time, the continued short-term compatibility between Base and the OP Stack suggests that collaboration within the broader ecosystem will not disappear overnight, even as infrastructure paths diverge.
What The Shift Means For The Future Of Layer 2
Base’s transition toward its own stack illustrates a broader maturation trend across the Layer 2 sector. As networks scale and user bases expand, the need for tailored infrastructure becomes more pronounced. Control over core technology can enable faster innovation, differentiated features, and tighter integration across ecosystem components.
For developers and users, the change may ultimately translate into improved performance and a more predictable upgrade cadence. For the broader market, it signals that Layer 2 networks are evolving from shared frameworks into distinct platforms with their own technical identities.
The move also reflects a strategic balancing act: maintaining interoperability and ecosystem alignment while building independent capabilities. How successfully Base navigates this transition could influence how other networks approach their own infrastructure strategies in the coming years.
Base’s decision to build a unified, self-operated software stack marks a defining moment in its evolution from a framework-based launch to a more autonomous network. By gradually reducing reliance on external dependencies and investing in proprietary infrastructure, the project aims to position itself for long-term scalability and innovation.
As the rollout progresses through its phased roadmap, the transition will serve as a closely watched case study in how Layer 2 networks mature, and how the balance between collaboration and independence shapes the future of blockchain scaling.
