Project Overview: Caldera


@Caldera Official Founded in 2022 in San Francisco, by Constellation Labs Inc. (operating under the Caldera name), it is a blockchain infrastructure company that provides Rollups-as-a-Service (RaaS). Its core product is Caldera Chains, which are customized Layer-2 blockchains based on optimistic Rollup technology, compatible with the Ethereum Virtual Machine (EVM), allowing standard Ethereum smart contract code to run without modification. Caldera aims to help developers quickly deploy high-throughput, low-latency dedicated blockchains through a modular blockchain architecture, addressing issues such as resource competition, high transaction costs, and network congestion on public chains.#caldera

Caldera's architecture consists of two core components:

  1. Rollup Engine: A modular operating system for launching high-performance custom chains on mainstream Layer-1 chains (like Ethereum) or frameworks (like Arbitrum, Optimism, ZKSync).

  2. Metalayer: An interoperability protocol that automatically connects all Caldera Chains into a unified network, providing shared liquidity and secure cross-chain bridging capabilities, creating the 'internet of chains.'

Key Features

  • High Performance: Caldera Chains can process hundreds of transactions per second, with confirmation times of less than one second, significantly enhancing dApp performance.

  • Highly Customizable: Supports custom features such as address whitelisting, sustainable revenue generation models, and no transaction fees, meeting the needs of specific dApps.

  • Ethereum Compatible: Developers can directly deploy Ethereum smart contracts on Caldera Chains without modifying code.

  • Modular Design: Through the Rollup Engine and Metalayer, Caldera provides flexible blockchain solutions that support integration with frameworks such as Arbitrum, Optimism, Base, and ZKSync.

  • Decentralized Data Support: By collaborating with projects like Seda, Caldera Chains can securely access off-chain data, enhancing functionality.

Ecosystem and Partners: Caldera has supported over 50 active Rollups, with a total locked value (TVL) exceeding $400 million, having processed over 750 million transactions, serving 27 million unique wallet addresses. Its partners include:

  • Projects like Manta Pacific, ApeChain, B3, etc., are building and scaling their on-chain ecosystems using Caldera's infrastructure.

  • BNB Chain: Joining the Caldera ecosystem through Metalayer and Caldera Bridge, bringing $180 billion in monthly DEX trading volume and 2 million daily active wallets.

  • Cronos Chain by Crypto.com: Enhancing scalability as its optimistic Rollup partner.

  • Adventure Gold DAO: Collaborating to build Loot Chain, a Layer-2 blockchain serving Lootverse.

  • Injective Labs: Bringing EVM into the Injective ecosystem through inEVM sovereign Rollup.

Native Token $ERA

The Caldera ecosystem is supported by the Caldera Foundation (an independent organization based in the Cayman Islands) and has launched the native token $ERA for:

  • Driving Metalayer and cross-chain bridging capabilities.

  • Supporting the long-term development of the ecosystem and decentralized governance.

  • Token distribution includes core team, early investors, and the community, with a 1-year lock-up period and 24 months of linear unlocking for the core team and investor tokens to ensure long-term interest alignment.

  • In July 2025, the initial airdrop pre-claim for the $ERA token has started; details can be found at claim.caldera.foundation.

Recent Updates

  • Caldera Bridge Preview: Launching in July 2025, the first consumer product based on Metalayer, simplifying cross-chain transactions and supporting interoperability between the Caldera ecosystem and other major liquidity hubs.

  • Binance HODLer Airdrop: $ERA was selected as the 27th HODLer airdrop project by Binance, with the trading pair $ERA/$TRY now live, attracting significant attention.

  • Recruitment and Funding: Caldera has received support from well-known venture capitals such as Sequoia Capital, Dragonfly, and Neo, and is actively recruiting engineers (React, Typescript, Go, Solidity). The company is one of the few profitable seed-stage crypto companies in 2023.
