  • cLabs has decided on its preferred tech stack for Celo’s Layer 2 transition.
  • The project received bids from multiple solution providers, including Polygon (MATIC) Labs.
  • Despite cLabs’ decision, Celo’s Layer 2 move still has to go through some governance processes.

Celo’s dilemma of deciding on the best tech stack for its planned transition to an Ethereum Layer 2 chain has finally ended after eight months.

In July 2023, cLabs, developers of the Celo Network, first revealed plans to transition to an Ethereum Layer 2 chain, tipping Optimism‘s OP Stack as the network’s tech stack of choice. However, what was likely intended to be a straightforward process quickly became a complicated affair after multiple solution providers, including Polygon (MATIC) Labs, Offchain Labs, and Matter Labs, threw their hats into the ring to bid for Celo’s business.


After months of comparisons and reviews, cLabs has made a decision, selecting what it believes to be the best stack for Celo’s needs.

Celo Comes Full Circle 

On Monday, April 22, cLabs disclosed that it had chosen the OP Stack for Celo’s Layer 2 transition, the same answer it had eight months prior.

According to the developers, they had considered several factors, including the time to production, Ethereum alignment, and positive-sum growth, before making their decision. They contended that the OP Stack presented “the most direct path forward,” while still being interoperable with other solutions, hinting at a future integration of Polygon’s Type 1 Prover.

cLabs asserted that with OP Stack, Celo will maintain its unique offerings like single block finality and low gas fees while also gaining 50% more throughput and greater security when bridging to Ethereum.

A Race to Deployment 

In line with Celo governance processes, cLabs has requested feedback on their decision, outlining two planned community calls on April 26 and May 2 to further discuss the plan before launching an on-chain community vote proper.


Developers hope that they can deploy the testnet of the Celo Layer 2, also known as CEL2, in the summer of 2024 if all goes well. 

Celo joins popular projects like Coinbase‘s Base and Worldcoin‘s World Chain to choose the OP Stack.
