Here's a ~100‑word snapshot of @Caldera Official · #Caldera · $ERA :

Caldera is a Rollup-as-a-Service (RaaS) platform built on Ethereum that enables developers to launch custom Layer‑2 rollups using frameworks like Optimism, Arbitrum, zkSync, and Polygon CDK. Its core innovation is the Metalayer, which connects rollups for cross‑rollup messaging, liquidity sharing, fast finality, and asset transfer across a unified coordination layer (Mitosis University).

On July 17, 2025, Caldera launched its native token $ERA, a 1 billion‑supply ERC‑20 used for omnichain gas, staking validator nodes, and governance voting in the Caldera DAO (Mitosis University). The launch included a retroactive airdrop distributing ~7% of the total supply (70 million tokens) to early users, testers, and ecosystem contributors (Mitosis University).

To date, Caldera supports 30–50+ live rollups, has processed hundreds of millions of transactions, and holds several hundred million dollars in TVL, positioning it as a leading modular infrastructure in Ethereum scaling (messari.io).
