Coinbase’s Base moves away from Optimism stack, OP token sinks
Coinbase-backed Base is taking control of its future. The Ethereum Layer‑2 network announced it is moving away from the Optimism OP Stack and launching a unified technology stack.
- Base, backed by Coinbase, announced it is moving away from the OP Stack and launching a unified in-house technology stack.
- The shift gives Base greater control over upgrades, with plans to double its hard fork cadence and streamline development.
- The market reacted swiftly, with the OP token falling nearly 20% following the announcement as investors reassessed Optimism’s role in the ecosystem.
This marks a major shift in how the network is built and upgraded.
Base chain goes solo: New unified stack unveiled
The new stack combines all core components — sequencer, client releases, and more — into a single codebase called base/base. The change makes updates faster, simpler, and more predictable. Base now plans six smaller, focused hard forks per year, double the previous pace.
Developers will face fewer obstacles, and node operators will find the system easier to manage.
“Over the coming months, Base is moving away from the OP Stack, however, we’ll continue to work with Optimism as a client of OP Enterprise: Mission-Critical Support. Once the transition is complete, upgrades and release information will be published through base/base,” the blog said.
Meanwhile, the native Optimism (OP) token sold off sharply after Base’s announcement, sliding as much as roughly 20% on the charts amid market concern over the shift away from the shared OP Stack framework.
Despite leaving the OP Stack, Base will stay compatible with existing specifications during the transition. Users and developers should experience no immediate disruptions. Base also confirmed it will continue collaborating with Optimism, providing support throughout the migration.
The move isn’t just technical. Base aims to strengthen decentralization by improving the Base Security Council and adding new signers. The team also plans enhanced security, zero-knowledge proofs, and better data availability layers in the future.
Node operators will eventually need the new Base client to stay in sync. The network promises clear guidance to ensure a smooth migration.
Industry watchers say the shift reflects a wider trend among Layer‑2 networks: building more control, speed, and flexibility. By breaking free from external dependencies, Base positions itself as a faster, leaner, and more independent network.
For developers, users, and investors, the upgrade signals faster updates, improved security, and a simpler experience, marking a bold new chapter for Coinbase’s Base.
