With the rapid development of Blockchain technology, Ethereum, as a pioneer of Decentralization applications, inevitably faces issues such as network congestion and high Transaction Cost. To tackle these challenges, Layer-2 scaling solutions have emerged, and Caldera (ERA) is redefining the interoperability and scalability of the Ethereum ecosystem with its innovative Rollup as a Service (RaaS) platform and Metalayer protocol.

Caldera launched in 2023 with the core mission of simplifying the creation process of Layer-2 solutions, providing a smooth bridge for Web2 developers to transition to the Web3 space. By offering efficient and customizable Rollup deployment tools, Caldera has rapidly emerged as one of the fastest-growing Rollup ecosystems in the world. As of July 2025, the Caldera ecosystem has attracted 1.8 million unique wallet users, with a total locked value (TVL) exceeding $550 million and a cumulative transaction volume of over 80 million, demonstrating strong growth momentum.

Caldera's vision is not limited to optimizing a single blockchain network, but rather aims to build a 'Rollup Internet' through its innovative Metalayer protocol. This groundbreaking concept is designed to enable seamless connections and interoperability between different Rollups, bringing revolutionary changes to the entire blockchain ecosystem.

Through Caldera's technological innovations, developers can more easily deploy and manage their own Layer-2 solutions, thereby accelerating the development and adoption of blockchain applications. This not only helps alleviate the pressure on the Ethereum mainnet but also provides users with a faster and more cost-effective transaction experience.

As Caldera continues to develop and refine its technology stack, we can expect to see more innovative applications and use cases emerge. This cross-Rollup interoperability has the potential to fundamentally change our understanding of Blockchain scalability, opening up new possibilities in areas such as Decentralized Finance (DeFi), Non-Fungible Tokens (NFTs), and the Metaverse.

Overall, Caldera is paving the way for the future development of Ethereum and the entire blockchain industry through its cutting-edge Layer-2 technology and cross-Rollup interoperability solutions. As more developers and users join the Caldera ecosystem, we have reason to believe that the mass adoption of blockchain technology will be accelerated.
