Caldera is building a platform that connects multiple rollups into a unified network, allowing each to keep its unique strengths while benefiting from Ethereum’s security and decentralization. At its core is the Metalayer, a special layer that links Optimistic and Zero-Knowledge (ZK) rollups so they can share resources and communicate seamlessly. This setup enables developers to grow faster, enjoy more flexibility, and connect across chains with ease. The $ERA token powers the network, serving as payment for cross-rollup transactions, staking for validator nodes, and voting on key upgrades and budgets. By creating a connected, modular rollup ecosystem, Caldera aims to make blockchain faster, cheaper, and more user-friendly, with low fees, quick applications, and a smooth multi-chain experience—ultimately positioning itself as the “Internet of Rollups” for Web3.
