Caldera is a modular “Rollup-as-a-Service” platform that enables teams to launch custom Ethereum Layer-2 rollups across various tech stacks—including Optimism, Arbitrum, zkSync, and Polygon—using a single-click deployment engine.
It powers a unified cross-rollup network, known as the Metalayer, facilitating messaging, interoperability, and composability between all rollups built on the platform.
