What Is Caldera (ERA)?
🔑 Key Takeaways:
Caldera is a Rollup-as-a-Service (RaaS) platform.
Developers can create custom app-specific rollups easily.
Built around two components:
Rollup Engine – for rollup creation and management.
Metalayer – for cross-rollup communication.
Rollups created with Caldera are interconnected, allowing easy asset and data sharing.

🚀 Why Caldera?
Building directly on Ethereum is slow and expensive during busy times.
Rollups solve this but are usually isolated.
Caldera solves that isolation by connecting rollups automatically, improving speed, reducing cost, and enhancing user experience.
