Caldera is a rollup platform on Ethereum that enables horizontal scalability and interoperability between rollups. Instead of optimizing a single blockchain, Caldera allows projects to launch customizable rollups while maintaining the security and decentralization of Ethereum. The platform features the Metalayer, a unifying layer designed to connect rollups in Optimistic and Zero-Knowledge (ZK) structures. This allows for coordination, communication, and resource sharing, preserving the distinct resources of each rollup. The native utility and governance token of Caldera, $ERA , is used for: - Transaction fees within the Metalayer for cross-rollup interactions. - Staking for validator nodes participating in the network. - Governance decisions on protocol updates and treasury allocations. #era
