#Gate Square Writing Contest Phase 2#  and  #ERA#  Caldera (ERA) is an infrastructure protocol that offers innovative solutions to blockchain technology's scalability and user experience challenges. It offers high-performance and customizable L2 and L3    rollups, specifically designed to overcome the limitations of the Ethereum network, such as high transaction fees and low transaction throughput. Caldera provides developers with fast, secure, and cost-effective blockchain solutions, enabling seamless communication and liquidity sharing between different blockchain networks through its Metalayer technology. In this article, we will examine in detail what Caldera (ERA) is, its RaaS platform, its Metalayer technology, its ecosystem, and the use cases of the ERA token.

Caldera is a Rollup-as-a-Service (RaaS) platform that enables developers to create high-performance, customizable L2 rollups on Ethereum and other major chains. By leveraging leading rollup frameworks, it allows projects to launch blockchain networks tailored to their needs in minutes. This allows developers to focus on the core functionality of their applications without the hassle of complex processes like infrastructure management or security reviews.

Caldera's modular flexibility allows projects to choose the execution environment, data availability layer, and native token (ETH) for gas fees. This feature is ideal for projects looking to optimize transaction speed, cost efficiency, and security.

Metalayer: A Revolution in Cross-Chain Interaction

One of Caldera's most striking features is its cross-chain interoperability framework, called Metalayer. Metalayer enables fast, secure, and cost-effective communication between different rollups. This technology enables transactions between over 100 rollups in seconds, eliminating the need for traditional cross-chain bridges. Key features of Metalayer include:

Unified Liquidity Access: Metalayer provides access to shared liquidity pools, providing more efficient markets and user-friendly experiences.

Simplified Cross-Chain Operations: Developers can focus on application logic, leaving complex cross-chain communication processes to Metalayer.

Intent-Based Execution: Developers simplify cross-chain transactions by defining high-level intents instead of low-level transactions. This enables rapid asset integration and seamless interoperability.

Secure Messaging: The messaging system is automatically deployed on every Caldera chain and supports secure data transfer and status readings.

Metalayer allows developers to create cross-chain dApps, pool liquidity, and establish secure bridges for high-value transactions.

What is ERA Token?

ERA is the native utility and governance token of the Caldera ecosystem. It has three main functions:

Omnichain Gas: Used as gas fees for cross-chain transactions on the Metalayer.

Staking and Security: Validators stake ERA to ensure network security and verify cross-chain messages.

Governance: ERA holders can vote on protocol updates, grant distribution, and foundation elections through Caldera Improvement Proposals (CIPs).

Caldera Ecosystem

The ERA Token Economy Isn't Just a Token, It's an Ecosystem

ERA token doesn't pursue short-term gains; it aims for sustainable growth.

As of 2025, Caldera hosts more than 30 mainnet blockchains, comprising approximately 25% of the Ethereum L2/L3 ecosystem. Its total value locked (TVL) has exceeded $600 million, with over 10 million unique wallet addresses processing 370 million transactions.

Featured Applications:

While the staking system provides passive income, the balance of supply and demand in circulation ensures long-term value preservation. A robust and attractive structure has been created for both investors and the sustainability of the system.

ERA Ecosystem Week, jointly organized by Gate and Caldera, has begun. Complete tasks, promote the project, and perhaps win amazing prizes.
