Caldera

Caldera, which operates under the corporate name Constellation Labs, is a San Francisco-based blockchain infrastructure company that provides rollups-as-a-service: it lets projects deploy their own application-specific layer-2 or layer-3 chain on established rollup stacks with a single click, without hiring in-house protocol or site-reliability engineers. Caldera handles deployment through ongoing maintenance, and markets low fees, customization options, security practices and 99.99% uptime service-level agreements. The platform is no-code, aimed at teams that can write Ethereum smart contracts but do not want to work at the underlying blockchain layer, and is intended to compress chain launch timelines from months or years to hours.

The company's second product line is the Metalayer, a unified rollup network and abstraction layer intended to connect rollups built on different frameworks — Optimism's OP Stack, Arbitrum Nitro, ZKsync's ZK Stack and Polygon's Chain Development Kit — so that multi-rollup applications can coordinate across both optimistic and zero-knowledge systems. Caldera positions the Metalayer as a response to fragmentation across Ethereum's layer-2 and layer-3 ecosystem, and describes developers as able to select their own data-availability, execution and settlement layers for a given chain. Development of the Metalayer was reinforced in November 2024 by the acquisition of the Hook team, which had previously built the Hook Odyssey perpetual-futures protocol as an Arbitrum Orbit rollup.

Founding story

Co-founders Matt Katz (CEO) and Parker Jou (CTO) met while studying computer science at Stanford University. Katz has described starting the company after concluding that developers wanted to build increasingly complex applications across many verticals, and that confining that activity to a single blockchain was untenable. The founders' prior experience spans Nvidia, Apple, Waymo, Skiff and Warp; the wider leadership team includes people from Coinbase, Google, Scale AI, Jump Trading, Amazon and Enya Labs.

Business model

Caldera sells managed rollup deployment and operation to third-party projects, taking on the infrastructure work — deployment, maintenance, reliability and security — that a project would otherwise staff internally, and layers network-level services such as the Metalayer interoperability network on top of its base of hosted chains.

Traction

As of the July 2024 Series A announcement, Caldera supported more than 50 rollups with 1.7 million unique wallets, over $800 million in total value locked and more than 59 million transactions completed. Named chains include Manta Pacific, ApeChain, Treasure, Plume Network, Towns, Kinto, RARI Chain, Injective and Zero Network by Zerion. Headcount stood at 20 in November 2024.

Latest developments

In November 2024 Caldera completed its first acquisition, buying Hook, the team behind the shuttered Hook Odyssey protocol, for an undisclosed sum; the Hook Odyssey protocol was wound down so the team could work on Caldera products, principally the Metalayer. Fenwick & West advised Caldera on the deal. Around the same time, Caldera addressed the Ethereum Foundation's "Beam Chain" consensus-layer proposal, with CEO Matt Katz arguing that projects will continue to want their own chains and that rollups remain the primary means of doing so.
