Rollup has already enabled Ethereum scaling, but behind the prosperity lies fragmentation: each chain is operating independently, liquidity is dispersed, and the user experience is fragmented. Today's multi-Rollup world is like the early local area networks of the internet: operating separately, but lacking a unified protocol.
Caldera ($ERA) aims to rewrite this situation. It is not just a RaaS tool, but targets the protocol layer of the Rollup internet. Modularity lowers the barrier to launching chains, allowing developers to quickly assemble technology stacks; customization allows application chains to differ based on needs; but the real killer feature is interoperability — Metalayer and Hyperlane are responsible for cross-chain messaging and liquidity transfer, and may even unify the gas experience, allowing users to switch Rollups as naturally as opening different web pages.
Currently, Caldera has already supported over 100 chains, including Manta, ApeChain, and Zerion, with a cumulative trading volume exceeding 27 million. The potential of $ERA lies in: if Metalayer becomes the de facto cross-Rollup settlement layer, it may evolve into a universal currency for the entire network.
Of course, the risks are equally sharp: cross-chain security is a core issue, and token value must be tied to real usage, otherwise $ERA could easily fall into the narrative trap.
In other words, Caldera's bet is: the Rollup world needs not just more chains, but a central protocol stack. And it is trying to play that role.
