#caldera Caldera is a rollup-as-a-service (RaaS) infrastructure platform that enables projects to deploy customizable, Ethereum-compatible Layer‑2 rollups. These rollups benefit from Ethereum security while offering performance and flexibility tailored to individual dApps or ecosystems .

It also introduces a Metalayer that connects diverse rollups via message passing, fast finality, and guardian nodes, tackling interoperability and fragmentation across Layer‑2 networks .

Founded by Matthew Katz (CEO) and Parker Jou (CTO), Caldera has already supported dozens of production rollups with significant transaction volume and ecosystem adoption .

The ERA token serves multiple critical functions within the Caldera protocol:

Cross-Rollup Gas & Fees: ERA is used for transaction and message fees on the Metalayer .

Staking & Validator Security: Validators (e.g. node operators, guardians) stake ERA to secure operations; slashing applies for underperformance .

Governance: ERA holders vote on upgrades, treasury allocations, and elect council members through the Caldera DAO via a Cayman‑based foundation .
