One of the core challenges of Ethereum scalability is the fragmentation of multiple Rollups. Caldera offers a solution for 'cross-Rollup collaboration': by using a Metalayer as a unified layer, it connects Rollups based on different frameworks (optimistic, zero-knowledge), allowing assets and data to flow across chains. For example, assets generated by a DeFi protocol in one Rollup can be transferred to another Rollup's NFT ecosystem through the Metalayer. The token drives this collaborative process (paying fees, staking for security), and developers can customize Rollup adaptation scenarios. This essentially builds a 'Rollup collaboration layer' within the Ethereum ecosystem, upgrading scalability from 'single-chain optimization' to 'network collaboration', opening up new spaces for enhancing ecosystem efficiency.
