Caldera's core innovation, the Metalayer, is the 'connecting magic' of the Ethereum Rollup ecosystem. It is not limited to a single Rollup optimization but connects the Rollup system of optimistic and zero-knowledge frameworks. Imagine different technical routes of Rollup, such as the optimistic DeFi chain and the zero-knowledge privacy chain, being able to share resources and interact with assets through Metalayer while preserving their own functionalities. This transforms the ecosystem from 'chain islands' into a collaborative network, allowing developers to create custom Rollups without the worry of isolation, integrating into a larger ecosystem. Token-driven Metalayer transactions ensure security through staking, and governance determines direction. Caldera is reshaping the collaborative rules of Ethereum Rollups with this logic.
