Caldera (ERA): A Modular Integrator for the Ethereum Scaling Ecosystem

Caldera is Ethereum's leading Rollup-as-a-Service (RaaS) platform, dedicated to addressing the fragmentation of the Layer 2/Layer 3 ecosystem. Its core innovation is the Metalayer interoperability layer, which enables cross-chain communication (e.g., seamless asset and data flow between Rollups from frameworks like Arbitrum and Optimism) through a decentralized validation network, integrating isolated chains into a unified network while preserving the unique characteristics of each.

The project has deployed over 75 application chains (including Manta Pacific and ApeChain), with a total locked-in value (TVL) exceeding $1 billion and processing over 80 million transactions across gaming, DeFi, and AI. 139 Its native ERA token (1 billion in total) combines utility and governance functions: it serves as the chain's gas token, is staked to ensure network security (with an annualized return of 8-15%), and supports community voting on protocol upgrades.

In July 2025, ERA was officially launched through an airdrop (accounting for 7% of the total supply), and the pre-mining activity attracted a large number of users to participate. Despite facing cross-chain security testing and regulatory risks, its modular design and one-click deployment capabilities are still regarded as key infrastructure for Ethereum's scale. #caldrea $ERA @Caldera Official
