What Is Caldera?

Caldera is a rollup platform on Ethereum that enables horizontal scaling and interoperability between rollups. Instead of optimizing a single blockchain, Caldera allows projects to launch customizable rollups while maintaining Ethereum's security and decentralization. The platform introduces the Metalayer, a unifying layer designed to connect rollups across Optimistic and Zero-Knowledge (ZK) frameworks. This enables coordination, communication, and resource sharing while preserving the distinct features of each rollup. Caldera's native utility and governance token, $ERA, is used for:

• Transaction fees within the Metalayer for cross-rollup interactions.
• Staking for validator nodes participating in the network.
• Governance decisions on protocol upgrades and treasury allocations.

Key Features:

• Rollup Engine: Projects can deploy rollups without requiring an engineering team.
• Message Passing & Relaying: Facilitates efficient data and asset transfers between rollups.
• Fast Finality & Preconfirmations: Improves transaction speed and security.
• Guardian Nodes: Provides additional security and decentralization for rollups.
• Native Yield: Supports ecosystem incentives and economic sustainability.

Who Founded Caldera? Caldera was developed by Constellation Labs, a blockchain research and development group focused on Ethereum scaling. The team includes engineers and protocol designers with experience in Web3 infrastructure. The CEO and co-founder is Matthew Katz, and the CTO and co-founder is Parker Jou.

Launched in 2023, Caldera has enabled over 60 rollups and processed more than 400 million transactions, with $500 million in Total Value Locked (TVL).

Some projects using Caldera's rollup infrastructure include:

• Manta Pacific
• inEVM by Injective
• ApeChain
• Treasure
• Plume Network
• Kinto
• RARI Chain
• Zero Network by Zerion
