What is Caldera (ERA)?

Caldera (ERA) is a rollup platform on Ethereum that describes itself as "The Internet of Rollups." Rather than optimizing a single blockchain, Caldera enables projects to launch customizable rollups while inheriting Ethereum's security and decentralization. Its core innovation is the Metalayer, a unifying layer designed to connect rollups across both Optimistic and Zero-Knowledge frameworks, allowing them to coordinate, communicate, and share resources without sacrificing their individual characteristics. Caldera operates as a Rollup-as-a-Service platform, letting developers deploy purpose-built Layer-2 and Layer-3 blockchains that settle on Ethereum. The ERA token has a total and max supply of 1,000,000,000 tokens, with circulating supply reported between roughly 148.5 million and 174.75 million depending on the data source. The project was founded in 2022 and launched its platform in 2023, and the ERA token began trading in 2025.

Who created Caldera?

Caldera was officially founded in 2022 by Matt Katz and Parker Jou. Matthew Katz serves as CEO and Co-Founder and previously worked in software engineering at Warp. Parker Jou serves as CTO and Co-Founder and previously worked in machine learning research at Waymo. James Semmonella leads Business Development and Growth at Caldera, having previously held the same function at Enya Labs. The broader team includes engineers and protocol designers with experience in Web3 infrastructure. The organization behind the project is Constellation Labs, a blockchain research and development group focused on Ethereum scaling. Caldera has raised $25 million in total funding, including a $15 million Series A round led by Founders Fund with participation from Sequoia Capital.

How does Caldera work?

Caldera functions as a rollup platform that lets projects deploy their own customizable rollups without needing to build an engineering team from scratch. The platform's Rollup Engine handles deployment, while the Metalayer connects rollups across Optimistic and Zero-Knowledge frameworks so they can communicate and share resources. Message passing and relaying facilitate efficient data and asset transfers between rollups. Fast finality and preconfirmations improve transaction speed and security, while Guardian Nodes provide additional security and decentralization for individual rollups. Native Yield supports ecosystem incentives and economic sustainability. All rollups built on Caldera settle on Ethereum, meaning they inherit the main network's security and decentralization while achieving high throughput and low cost. Since launching in 2023, Caldera has enabled over 60 rollups and processed more than 400 million transactions, with $500 million in Total Value Locked.

What makes Caldera unique and valuable?

Caldera's primary differentiator is its horizontal scaling approach. Instead of trying to optimize a single blockchain, it enables an interconnected network of purpose-built chains that all settle on Ethereum. The Metalayer is central to this design, providing a unifying layer that connects rollups across different frameworks while preserving each rollup's distinct features. This addresses a key problem in the Ethereum ecosystem: rollups have proliferated, but interoperability between them remains limited. By simplifying the process of launching L2 solutions, Caldera lowers the barrier for developers, including those coming from Web2. The platform's track record of over 60 rollups and more than 400 million transactions demonstrates real adoption. For token holders, ERA provides utility across transaction fees, staking, and governance, tying the token directly to the network's operation and long-term development.

What is Caldera used for?

The ERA token serves three primary functions within the Caldera ecosystem. First, it is used to pay transaction fees within the Metalayer for cross-rollup interactions, making it integral to the platform's interoperability layer. Second, ERA can be staked by validator nodes participating in the network, providing a mechanism for securing the protocol and earning rewards. Third, ERA holders can participate in governance decisions on protocol upgrades and treasury allocations, giving the community a voice in the project's direction. Beyond the token itself, Caldera's platform is used by projects to deploy customizable Layer-2 and Layer-3 blockchains. Notable projects using Caldera's rollup infrastructure include Manta Pacific, inEVM by Injective, ApeChain, Treasure, Plume Network, Kinto, RARI Chain, and Zero Network by Zerion.

How Is the Caldera ecosystem developing?

Caldera's ecosystem has expanded to include a range of projects across DeFi, gaming, and infrastructure. Manta Pacific, inEVM by Injective, ApeChain, Treasure, Plume Network, Kinto, RARI Chain, and Zero Network by Zerion all use Caldera's rollup infrastructure. The platform launched in 2023 and has since enabled over 60 rollups and processed more than 400 million transactions, with $500 million in Total Value Locked. In December 2025, Caldera announced that ERA went live on Arbitrum One as part of its Onchain Expansion Program, described as deeply integrated across the ecosystem. The project also maintains an active community through its Twitter account and website, and a Community Badge is available on CoinMarketCap. Governance via the ERA token allows holders to influence protocol upgrades and treasury allocations as the ecosystem continues to grow.

How to mine Caldera?

Caldera does not use traditional proof-of-work mining. Instead, the network relies on validator nodes that participate in securing the protocol, and ERA tokens can be staked to support this process. Staking ERA allows holders to contribute to the network's security and potentially earn rewards. The specific requirements and reward structure for running a validator node are best confirmed through Caldera's official documentation. For most token holders, staking is the primary way to participate in the network's economic model without running infrastructure. As with any staking mechanism, participants should review the protocol's official resources to understand lock-up periods, slashing conditions, and reward rates before committing tokens.

How to keep your Caldera Coin safe?

Since ERA is an ERC20 token on Ethereum, it can be stored in any wallet that supports ERC20 assets. For long-term holdings, a hardware wallet provides the strongest protection by keeping private keys offline. For more active use, a reputable software wallet or a wallet provided by a trusted platform can be used, but users should always verify contract addresses before interacting with any token. Because ERA is available on multiple trading venues and across 157 to 163 active markets, it is important to double-check the token contract when transferring or trading. Never share private keys or seed phrases, and be cautious of phishing sites that mimic official project pages. Given the broader market risks, including extreme volatility and the potential loss of entire capital, investors should only commit funds they can afford to lose and consider using hardware wallets for significant holdings.
