What is Caldera?

Caldera is a rollup platform built on Ethereum, focused on horizontal scaling and interoperability between rollups. It enables projects to launch customizable rollups while using Ethereum as the base security and decentralization layer. The description does not provide a founding year, founder names, token supply cap, or governance model.

The platform introduces the Metalayer, described as a unifying layer intended to connect rollups across Optimistic and zero-knowledge (ZK) frameworks. It is intended to coordinate rollups, support communication between them, and enable resource sharing while preserving the distinct features of each rollup.
