@Caldera Official ($ERA) serves as the native token of the Caldera platform, backed by an innovative solution based on Ethereum—"Rollup-as-a-Service" (RaaS, which means rollup as a service). Simply put, this solution provides a "quick build toolkit for second-layer blockchains" for Web3 projects: any project can quickly launch its own customized rollup (Ethereum Layer 2 network) without starting from scratch to build underlying technology, preserving the security foundation of the Ethereum mainnet while enjoying the high throughput and low cost advantages of Layer 2 networks.
