Caldera's Metalayer is an underrated core innovation. Its design goal is simple: to allow different chains to communicate as freely as applications do. In the past, cross-chain interactions were a hassle, requiring developers to write complex bridging code and worry about security risks. But in Metalayer, all of this has been abstracted away.
Developers only need to express their intent, such as 'I want to transfer this asset from chain A to chain B,' and Metalayer will automatically handle the underlying logic, making the complex cross-chain process transparent to the user.
It's like Doraemon's Anywhere Door; you just need to tell it the destination, and the system takes care of the rest. More importantly, this cross-chain communication is not limited to assets but also includes information and calls, meaning applications on different chains can work together. For example, an item from a gaming chain can be used as collateral for a loan on a financial chain; an identity from a social chain can seamlessly connect to another application.
Metalayer acts like a lubricant, transforming the entire ecosystem from fragmentation to integration. Its emergence addresses the issue of Rollup fragmentation and truly turns the multi-chain ecosystem into a unified network.
