In a significant move for the decentralized finance (DeFi) ecosystem, Coinbase’s Base is breaking away from its reliance on Optimism’s technology stack to develop its own unified software architecture. Launched in 2023 as an Optimism chain, Base is now transitioning to a custom tech stack to streamline operations and accelerate innovation, according to an official announcement from the Base team.
A New Era for Base
The decision to transition to a custom architecture is driven by a desire to reduce dependencies on external service providers and expedite the deployment of new upgrades. “Consolidating into Base changes how Base packages and releases software for the network. We will ship one official distribution for each upgrade: a single Base binary for operating nodes on the network,” the team stated.
Simplifying the Sequencer
The shift is also expected to simplify the Base network’s sequencer, a critical component that helps network validators order transactions. The sequencer will become more efficient and easier to manage, enhancing the overall performance and reliability of the Base network.

Roadmap and Implementation
The transition will be rolled out in four phases, with node runners required to shift to the new Base client over the next several months to ensure smooth upgrades. This phased approach is designed to minimize disruptions and ensure a seamless transition for all participants.
Ethereum Co-Founder Revises Stance on Layer-2 Scaling
The move by Base comes amid a broader shift in the Ethereum ecosystem. Earlier this month, Ethereum co-founder Vitalik Buterin revised his stance on layer-2 (L2) scaling networks. Buterin acknowledged that L2s are taking longer than expected to achieve full decentralization and noted that the Ethereum layer-1 (L1) network is already scaling effectively with record-low fees.
“The original vision of L2s and their role in Ethereum no longer makes sense, and we need a new path,” Buterin said in February.
Buterin’s comments sparked mixed reactions from L2 teams. Some, like Base founder Jesse Pollak, agreed that L2s must evolve beyond being merely cheaper execution layers for Ethereum. “It’s great to see Ethereum scaling L1 – this is a win for the entire ecosystem. Going forward, L2s can’t just be ‘Ethereum but cheaper,’” Pollak said in response.
The Future of Layer-2 Networks
Despite the challenges, there are more than 128 different Ethereum L2 scaling networks at the time of publication, according to L2Beat. These networks continue to play a crucial role in the broader Ethereum ecosystem, offering solutions for transaction speed, cost, and scalability.
Base’s move to a custom tech stack is a bold step that could set a new standard for L2 networks. By reducing dependencies and streamlining operations, Base is positioning itself to be a leader in the rapidly evolving DeFi landscape. As the Ethereum ecosystem continues to grow, the success of initiatives like Base will be closely watched by developers, investors, and users alike.
In the coming months, the focus will be on the successful execution of the transition and the realization of the promised benefits. If Base can achieve its goals, it may inspire other L2 networks to follow a similar path, ultimately contributing to a more robust and decentralized Ethereum ecosystem.
