As Ethereum scalability solutions advance at breakneck speed, fragmentation has become a critical challenge threatening the ecosystem’s path to widespread adoption.
This guide examines Caldera, a next-generation infrastructure platform. Caldera introduces the Metalayer—a breakthrough that unites Ethereum’s rollups. You’ll learn how Caldera’s native ERA token underpins this novel system, explore its tokenomics and real-world use cases, and see how the technology aims to redefine blockchain interoperability and scalability.
Caldera began as a premier rollup platform and has since become the architect of Ethereum’s first Metalayer. Debuting as a Rollup-as-a-Service (RaaS) platform, Caldera empowers projects to launch custom rollups with a single click across multiple frameworks—including Optimism, Arbitrum, ZKsync, and Polygon.
The platform has rapidly grown into one of the world’s fastest-expanding rollup ecosystems. Caldera enables web3 teams to configure and deploy over 60 high-performance rollups. Today, the Caldera ecosystem boasts 1.8 million unique wallets holding over $550 million in total value locked (TVL) and more than 80 million completed transactions. Leading chains include Manta Pacific, Injective’s inEVM, ApeChain, Treasure, Plume Network, Towns, Kinto, RARI Chain, and Zerion’s Zero Network.
ERA is Caldera’s native token—the core of the Metalayer protocol—offering both utility and governance. As Caldera transitions from a simple RaaS platform to a comprehensive rollup abstraction layer, ERA holders gain key rights: on-chain governance participation, staking for network security, and seamless cross-chain operations.

Ethereum’s rollup-centric strategy has driven explosive growth, with over $38.5 billion migrating to Layer 2 and Layer 3 since 2020. Yet this success has introduced a new challenge: rollup fragmentation, which threatens the ecosystem’s long-term viability.
Current rollups act as isolated “city-states” and face three fundamental issues:
Caldera’s model draws from the early internet, when disconnected protocols and networks struggled with connectivity. Standardized protocols like TCP/IP fueled the internet’s growth by providing a universal communications language. Caldera’s Metalayer aims to do for Ethereum rollups what TCP/IP did for the internet—unify disparate protocols for seamless interaction.
Caldera’s founders recognized that simply building a faster blockchain isn’t enough to scale Ethereum. Instead, they envisioned web-scale performance via horizontal scaling with rollups.
The platform’s initial launch was revolutionary: enabling one-click deployment of custom rollups with no engineering team required. Caldera managed deployment, setup, ongoing maintenance, and security—letting projects focus on their vision, not infrastructure headaches.
This vision quickly proved itself, as Caldera became one of the world’s fastest-growing rollup ecosystems. Its ability to support multiple rollup frameworks—Optimism, Arbitrum, ZKsync, and Polygon—drew a wide range of projects seeking tailored scalability solutions.
As the ecosystem expanded and rollup fragmentation became more evident, Caldera moved beyond its RaaS roots. The team realized that while rollups scale Ethereum, they require a unifying layer to prevent the ecosystem from splintering into isolated protocols. This insight sparked the Metalayer concept and the launch of the ERA token as the native utility asset powering this unified infrastructure.
Caldera’s Metalayer is a leap forward in rollup architecture, operating as a unifying layer for all Ethereum rollups. It delivers seamless coordination, cross-chain communication, and resource sharing—while preserving the unique features of each rollup.
This innovation directly addresses fragmentation, enabling a common protocol for interaction across different rollup frameworks. The Metalayer breaks down barriers that once isolated these ecosystems. Developers can build apps leveraging the strengths of multiple rollups at once, while users move freely across chains with no technical friction.
Metalayer validators post aggregated state root hashes for all chains, so users on any rollup can submit Merkle proofs from other chains. This enables unprecedented cross-chain state access while maintaining security, making complex, multi-rollup state verification practical without sacrificing decentralization.
The protocol provides the foundation for ecosystem-native economies, distributing value among the most committed participants and creating sustainable, long-term incentives. This model aligns developers, users, and validators—driving healthy ecosystem growth.
The Metalayer streamlines Ethereum app development with tools for building high-performance, user-centric applications. Developers get unified APIs, standardized tools, and comprehensive documentation—making multi-rollup development accessible and efficient.
Developers can now build complex apps operating across multiple rollups—harnessing each system’s unique strengths and delivering seamless user experiences ecosystem-wide. This enables use cases like DeFi platforms using optimistic rollups for speed and ZK rollups for privacy, all within a single interface.
For example, a DeFi app might execute high-frequency trades on a speed-optimized rollup and keep compliance records on a privacy-focused rollup, with users never needing to switch chains or manage multiple wallets.
DeFi platforms can access liquidity and execute transactions across the entire Ethereum rollup ecosystem, not just on individual chains—boosting capital efficiency and unlocking new, advanced financial products.
Lending protocols aggregate liquidity from several rollups, DEXs find better prices from deeper liquidity pools, and yield platforms automate position optimization across networks for maximum returns.
Web3 infrastructure providers can deploy services once and serve the full Ethereum rollup ecosystem via the Metalayer—instead of managing separate deployments for each chain. This slashes operational complexity and enables robust service offerings.
Oracles, indexers, data providers, and custody solutions integrate with the Metalayer once and instantly reach all connected rollups, driving down development and maintenance costs.
Enterprises can deploy rollups that instantly benefit from the ecosystem’s shared connectivity and security—removing the isolation of private blockchain deployments and making enterprise adoption far more appealing.
Organizations maintain private rollups for sensitive operations and selectively connect to the public ecosystem for interoperable functions like payments, identity, or supply chain management.
Gaming protocols use the Metalayer to craft experiences spanning multiple rollups, enabling complex game mechanics with different chains optimized for distinct purposes. For instance, one rollup handles rapid gameplay, another stores valuable assets—balancing speed and security.
Metaverse worlds can span multiple rollups, with regions or features on chains tailored to their specific needs, while users move smoothly between them with no technical barriers.
The ERA token distribution is engineered for long-term ecosystem growth and balanced stakeholder participation:
The unlock schedule is structured to avoid market disruption and ensure sustainable token distribution, with specific vesting and cliff schedules for each allocation. Airdrop tokens are available immediately to boost community engagement and adoption.
This transparent, well-designed model highlights Caldera’s commitment to long-term sustainability and incentive alignment across the ecosystem.
ERA is the standard gas token for all Metalayer operations. It’s the fuel for cross-chain transactions—fees for initiating cross-chain activity and data transfers are paid in ERA, creating unified economic incentives ecosystem-wide.
This model streamlines user experience by removing the need to hold multiple gas tokens for different rollups, while ensuring a predictable, sustainable value flow for validators and node operators maintaining the Metalayer.
Nodes must stake ERA tokens to join the Metalayer network. Proof-of-stake or re-staking consensus runs on these stakes, with node participation tied directly to the amount of ERA staked or delegated.
This aligns validator incentives with network health: malicious or inefficient validators risk losing their stake, while reliable operators earn rewards proportional to their contribution. Holders who prefer not to run nodes can delegate tokens to trusted validators and share staking rewards—helping secure the network.
Special-purpose subnets alongside the Metalayer deliver custom features for rollups—like generating and relaying on-chain zero-knowledge proofs. These subnets also use ERA for proof-of-stake consensus.
This modular architecture lets the ecosystem add new capabilities without overloading the main Metalayer, keeping operations efficient while supporting specialized rollup needs.
ERA holders have full on-chain governance rights over Caldera protocol upgrades and ecosystem decisions:
Caldera’s roadmap is focused on making the Metalayer the backbone of Ethereum’s rollup ecosystem. The platform will evolve from linking today’s rollups into the foundation for the next generation of blockchain apps.
Priorities include expanding subnet capabilities for specialized use cases, enhancing rollup communication protocols, and rolling out advanced governance to truly decentralize control. As the rollup ecosystem grows, Caldera’s Metalayer will scale to hundreds of chains—while maintaining seamless interoperability.
Caldera’s long-term vision is a self-sustaining ecosystem where rollups can innovate independently yet benefit from shared security, liquidity, and infrastructure—much like TCP/IP enabled the internet’s growth. Caldera aims to be the backbone of Ethereum’s scalability solution.
Success will be measured by Caldera’s ability to erase rollup fragmentation while preserving the innovation and customization that make rollups attractive for developers and projects seeking bespoke blockchain solutions. The team partners closely with the community to ensure the protocol’s evolution meets the needs and ambitions of all ecosystem members.
Caldera plays in the fast-evolving Layer 2 infrastructure space, where several projects are racing to solve Ethereum’s scalability—each with a different approach.
Major competitors include established Layer 2 platforms like Polygon (MATIC), a multi-faceted ecosystem; Arbitrum (ARB), focused on optimistic rollups; and Optimism (OP), a pioneer in the space. Most offer individual scaling solutions—not a unified infrastructure.
Infrastructure competitors include Cosmos and its Inter-Blockchain Communication (IBC) protocol, and Polkadot’s parachain architecture—both tackling blockchain interoperability via different technical means.
Caldera’s defining vision is unification: instead of competing with existing rollups, it connects them—building a stronger ecosystem where each rollup keeps its strengths and gains true interoperability.
