BNB HODLer Issue 27 Caldera $ERA is here Caldera: Reconstructing the cross-chain infrastructure of the Rollup internet Caldera aims to create a Rollup interconnection network that transforms blockchains into underlying infrastructure through modular design, with native cross-chain capabilities integrated. Its architecture is driven by two core components: Rollup Engine: Supports developers in quickly deploying high-performance custom chains, lowering the barriers to chain construction; Metalayer Middleware: Provides native interoperability features such as cross-chain communication, liquidity aggregation, and intent execution, without relying on third-party bridges. Key Progress: Ecosystem covers 100+ chains (including 30 mainnets), with a total locked value (TVL) exceeding $400 million, and an average of over 250,000 active addresses daily; Partners include leading projects like Manta and Apechain, and integrates modular solutions like Celestia and EigenDA. Innovations of Metalayer: As a general-purpose middleware designed specifically for Rollups, it surpasses traditional cross-chain tools by providing: Full-chain read/write: Directly call contracts and data from other chains; Intent broadcasting: Supports asynchronous task execution; Verification network: Compatible with frameworks like Hyperlane, ensuring secure message routing. Token Economics and Governance: The $ERA token is used for paying cross-chain gas fees, staking validation, governance voting, and serves as access credentials for liquidity pools. Vision: Caldera is not limited to a single chain but aims to become a connecting system between Rollups—the more chains there are, the stronger the network effect. Its goal is to redefine the interoperability and composability of the future Rollup world, promoting the multi-chain ecosystem towards frictionless collaboration.
