What Is Caldera (ERA) and How Does It Work?
Caldera (ERA) is a Rollups-as-a-Service (RaaS) platform designed to make blockchain scaling accessible and developer-friendly. It allows projects to launch their own customizable
Layer‑2 rollups on
Ethereum without dealing with complex infrastructure. Developers can choose from multiple tech stacks like
Optimism Bedrock,
Arbitrum Orbit,
Polygon CDK, and
zkSync’s ZK Stack. With a few clicks, they can configure their chain, select a
data availability layer, and deploy, enabling high-performance rollups that support faster transactions and lower fees.
What sets Caldera apart is its Metalayer, an interoperability framework that connects all Caldera-powered rollups. This shared layer facilitates seamless cross-chain communication, pooled
liquidity, and composability, solving the fragmentation issues seen in most rollup ecosystems. Developers and users benefit from instant bridging, unified messaging, and ecosystem-wide liquidity without extra engineering effort. Paired with Caldera’s SDKs and APIs, it offers a plug-and-play solution for building scalable and interconnected
Web3 applications.
With over 100 active rollups, millions of users, and hundreds of millions of transactions processed, Caldera has become a critical scaling solution for projects like
Manta Pacific,
ApeChain, and
Injective. It combines enterprise-grade uptime, developer tools, and modular infrastructure to deliver a robust environment for both startups and large-scale blockchain platforms.
When Was Caldera Launched?
Caldera (ERA) was founded in 2022 by Constellation Labs (operating as Caldera Foundation), backed by leading investors including Founders Fund, Sequoia, Dragonfly, and Arkstream. The founding team, led by CEO Matthew “Matt” Katz and CTO Parker Jou, set out to address Ethereum’s scalability challenges by offering a streamlined “rollup-in-a-box” solution for developers.
The official launch of Caldera occurred in 2022, introducing its core platform: the Rollup Engine and the Metalayer. This empowered users to deploy custom
Layer‑2 rollups in a single click, while ensuring interoperability through shared messaging and pooled liquidity across chains.
Timeline & Roadmap Highlights
• Company founding & platform debut in 2022: Caldera launched, enabling one-click rollup creation with modular infrastructure support.
• Series A funding ($15M) in July 2024: Led by Founders Fund, with Dragonfly, Sequoia, Arkstream, and Lattice; funds allocated toward expanding the Metalayer and interoperability work.
• Rollout & optimization of Metalayer and Rollup Engine upgrades (Early–Mid 2025), enabling integration of over 100 rollups, improved cross-chain messaging, and broadening technical capabilities.
• ERA token launch & airdrop (Jul 2025): Pre-claims began on July 10, 2025, with a retroactive airdrop distributing 7% of the total 1 billion‑coin supply to early ecosystem participants. ERA will serve as the native gas token, staking asset, and governance tool on Caldera-powered rollups.
What Is the ERA Token Utility?
The ERA token is the native utility and governance token of the Caldera ecosystem. It powers gas payments on all Caldera rollups, incentivizes
validators and sequencers, and secures the network through
staking. ERA also enables decentralized governance, allowing token holders to propose and vote on protocol upgrades, treasury allocations, and technical council elections. Additionally, ERA is used within the Metalayer for cross-rollup transactions and liquidity provisioning.
What Is Caldera Tokenomics?
Caldera's
total supply comprises 1,000,000,000 ERA tokens minted at the Token Generation Event (TGE).
ERA Token Allocation
• Early Backers & Investors: 32.06% (320.6 M ERA)

• Core Team: 14.75% (147.5 M ERA)
• R&D: 10.25% (102.5 M ERA)
• Retroactive Airdrop: 7% (70 M ERA)
How to Claim Caldera Airdrop
The Caldera airdrop is a genesis token distribution where 7% of the total 1 billion ERA supply (~70 million ERA) is allocated to early ecosystem participants. It rewards activity across Caldera-powered networks, testnet contributions, modular ecosystem participants, community builders,
NFT holders, and public goods developers.
Key Dates for Claiming ERA Tokens
• Snapshot Date: March 5, 2025

How Does Caldera’s Metalayer Enhance Interoperability?
Caldera’s Metalayer enhances interoperability by acting as a shared framework that connects all Caldera-powered rollups, enabling seamless communication and liquidity across chains. It allows developers to build application-specific rollups that can interact natively with each other, supporting cross-rollup messaging, intent-based transactions, and pooled liquidity without additional infrastructure. By integrating partners like Hyperlane, Across, and Eco for secure bridging and message passing, the Metalayer transforms isolated rollups into a unified ecosystem where assets, data, and
dApps flow freely, improving user experience and fostering a composable Web3 environment.
What Blockchain Network Does Caldera Operate on?
Caldera operates as a Layer‑2 Rollups-as-a-Service (RaaS) platform primarily built on Ethereum, enabling its ecosystem of app-specific rollups to settle transactions on the Ethereum blockchain. Each rollup uses Ethereum (or other DAs like
Celestia or
NEAR) for settlement and data availability, while Caldera’s Metalayer interconnects them into a unified ecosystem. Through this shared interoperability network, transactions, messages, and liquidity can securely pass between chains, allowing projects to leverage Ethereum's decentralization while benefiting from customizable execution environments and high throughput.
Which Wallets Support ERA Tokens?
For seamless access, you can store ERA directly in your BingX Spot wallet. Just deposit your tokens under the ERA/USDT pair, and enjoy full custody within the platform. BingX also supports withdrawing to external
Ethereum-compatible (EVM) wallets, giving users flexibility to manage, trade, or stake their ERA as needed.
Beyond BingX, ERA tokens are supported by many EVM-compatible wallets like
MetaMask and
Trust Wallet, enabling easy deposits, withdrawals, and use across Caldera-based rollups. For added security,
hardware wallets such as
Ledger, Trezor, and Cypherock X1 offer offline key storage and advanced protection, making them ideal for long-term storage. Additionally, wallets supporting ENS domains can use .era domains (e.g., yourname.era), which integrate seamlessly with Caldera’s domain system.
Is Caldera (ERA) a Good Investment?
Caldera (ERA) stands out as a potential investment because it powers a rapidly growing Rollups-as-a-Service (RaaS) ecosystem that simplifies blockchain scalability. With its modular infrastructure and Metalayer interoperability framework, Caldera enables developers to deploy custom Layer-2 rollups that are instantly connected for cross-chain messaging and shared liquidity. This addresses one of Ethereum’s biggest challenges, fragmentation across rollups, and positions Caldera as a backbone for a unified Web3 ecosystem. As more dApps, gaming platforms, and DeFi protocols launch on Caldera-powered rollups, demand for ERA as the native gas token and governance asset could increase significantly.
Moreover, ERA’s well-designed
tokenomics support long-term growth and ecosystem alignment. The fixed supply of 1 billion tokens, combined with staking incentives, governance utility, and use in transaction fees across all Caldera chains, creates multiple layers of demand. The platform’s strong backing from top-tier investors like Founders Fund and Sequoia, coupled with partnerships across the modular blockchain space, further strengthens its growth prospects. For investors seeking exposure to Ethereum scalability solutions and cross-rollup interoperability, ERA offers a compelling narrative tied to one of the most critical infrastructure layers in Web3.
