Caldera is a blockchain infrastructure platform offering Rollup-as-a-Service (RaaS) in the Ethereum ecosystem. The project's goal is to enable developers to create and manage customized Layer-2 (L2) chains with just a few clicks or via API, catering to specialized applications like DeFi, gaming, NFTs, or social networks.

Caldera stands out with two core components:

  • Rollup Engine – A cloud coordination tool that allows quick rollup deployment, supporting multiple frameworks from Optimistic Rollup (like Arbitrum Nitro) to ZK Rollup (like zkSync).

  • Metalayer – An intermediate layer that helps connect, share liquidity, and transmit information between different rollups, transforming them from 'isolated islands' into a seamless interactive network.

How It Works

Deploy Rollup

Developers can choose the execution layer, data availability layer, and performance configuration. Deployment occurs quickly through the Rollup Engine.

Connect via Metalayer

Immediately after creation, the rollup will be integrated into Metalayer, allowing:

  • Near-instant cross-chain stablecoin transfers

  • Liquidity sharing between L2s

  • Smooth cross-chain messaging sending and receiving

Scalability and flexibility

Thanks to a modular architecture, rollups can easily upgrade resources, change parameters, or integrate new features without affecting operation.

ERA Token

ERA is the native token of the Caldera ecosystem, with a fixed total supply of 1 billion tokens.
Main Role:

  • Gas Fees: Pay transaction fees on Caldera using ERA or ETH

  • Staking & Security: Stake ERA to support cybersecurity and data layers

  • Governance: Participate in voting for Metalayer updates, reserve fund, and system policies

Allocation:

  • Retroactive Airdrop: 30%

  • Team & Advisors: 20% (lockup 2–4 years)

  • Investors & Treasury: 30%

  • Ecosystem incentives: 20%

Notable Point: Binance will distribute 20 million ERA in the 'BNB HODLer Airdrop' program.

Technical Data and Ecosystem

  • Infrastructure: The Aggregation Engine provides node services, block explorer, modular tools; Metalayer has the Intents Engine and secure messaging protocol.

  • User Scale: 27.6 million unique users, ~250,000 daily active users

  • Activity: Over 750 million transactions, 60+ NFT collections, projected TVL to reach $550 million by mid-2025

Prospects & Competition

Price Forecast:

  • 2025: $1.10 – $1.40

  • 2026–2027: $2 – $4.50

  • 2030: $6 – $15

Advantages:

  • Unique Metalayer technology, supporting multiple VMs (Arbitrum, ZK, Optimism)

  • High liquidity and visibility thanks to listings on major exchanges

  • Developer-friendly SDK and API

Risks:

  • Direct competition with giants like Polygon, Arbitrum Orbit, zkSync

  • Selling pressure from token supply and early investors

  • Technical risks or negative publicity

Conclusion

Caldera offers an 'infrastructure-as-a-service' approach for Ethereum Layer-2, optimizing scalability, security, and cross-chain connectivity. With Metalayer and a rapidly growing ecosystem, ERA has the potential to become one of the pillars of blockchain infrastructure in the 2025–2030 period. However, investors need to consider competitive risks and token allocation strategies before participating.
