Interoperability between different chains in the blockchain ecosystem has always been a challenge. This issue can be likened to the situation where different appliances use different plugs. Caldera has proposed an innovative solution called Metalayer, which acts like a universal socket.

The design of Metalayer allows various types of blockchains, including Optimistic, ZK, and different structures of Rollup, to connect to this unified platform. This design enables different blockchains to collaborate under consistent rules, greatly improving the efficiency of the entire ecosystem.

In this system, the ERA token plays an important role and can be regarded as the energy currency of this 'socket system'. Whether for transactions, information synchronization, or participating in governance, ERA is required.

Currently, the market price of ERA is around $0.95. This relatively low price may reflect that the market has not yet fully recognized the potential of this system in the future. As more blockchain projects integrate with Metalayer, the demand for ERA may significantly increase.

Some analysis suggests that if the price of ERA rises to around $2.7 by the end of the year, it may indicate that the entire ecosystem begins to recognize and price ERA. This would be an important signal for the widespread adoption of Caldera's Metalayer technology.

The enhancement of cross-chain interoperability will open new possibilities for the further development and application of blockchain technology. Over time, we will be able to see more clearly the impact of this innovation from Caldera on the entire blockchain ecosystem.
