| What to Know: - Base leaves OP Stack for a unified, in-house codebase. - Consolidated codebase accelerates upgrades and reduces cross-team coordination overhead. - Centralized releases and testing speed features while preserving Ethereum settlement guarantees. |

Base, the Ethereum layer-2 incubated by Coinbase, is moving off the Optimism OP Stack to a unified in-house architecture. The shift consolidates protocol components into a single codebase intended to speed upgrades and reduce coordination overhead.
Operationally, a unified codebase centralizes release engineering and testing, which can lower cross-repository breakage and simplify incident response. For users and developers, the stated goal is faster feature delivery while maintaining settlement guarantees anchored to Ethereum.
The OP Stack offers a modular toolkit around optimistic rollup design, while Base’s unified codebase prioritizes tighter integration and reduced external dependencies. In practice, this means converging around one implementation path and a more predictable upgrade train for node operators and dApp teams.
As reported by CryptoBriefing, Base framed the move as operational streamlining to cut third‑party dependencies and accelerate releases. “Reduce dependencies on external service providers and shorten the time it takes to ship new upgrades,” said Jesse Pollak, Head of Base at Coinbase. The report also notes a plan to ship one official binary per upgrade and target roughly six hard forks a year, up from about three, with scope to incorporate trusted-execution and zero-knowledge proofs alongside a simplified sequencer design.
As reported by The Block, Base remains at Vitalik Buterin’s Stage 1 decentralization today and is adding an independent signer to its security council while exploring a path to Stage 2. That framing clarifies trust assumptions around upgrade authority and emergency actions, even as the network remains non-custodial with funds anchored to Ethereum. A faster cadence of hard forks may improve responsiveness but can raise operational demands on validators, indexers, and infrastructure providers.
According to Coinpaper, the project intends to keep the protocol open source, consolidate development in a unified “base/base” repository, and preserve short‑term OP Stack specification compatibility so alternative clients and existing tooling continue to function. That approach aims to balance autonomy with interoperability for teams built around OP Stack standards.
