Editor's Note: On July 16, according to an official announcement, the Binance HODLer Airdrop has launched its 27th project - Caldera (ERA). Its tokenomics have also been revealed: Caldera (ERA) has a total token supply of 1 billion, with the HODLer airdrop accounting for 2% of the total, initial circulating tokens accounting for 14.85% of the maximum supply, and an additional 20,000,000 ERA to be used for market activities 6 months after listing. This article was first published on July 30, 2024, providing a detailed introduction to Caldera, and BlockBeats reprinted the original article as follows:

In the multi-chain world of Web3, each Layer 2 solution is like a isolated island, acting on its own and not communicating with others. However, in this fragmented ecosystem, a project called Caldera is working to bridge the gap, building an interconnected Metalayer to achieve seamless connectivity between Layer 2 and Layer 3. Today, let's take three minutes to delve into this project.

1. What is Caldera?

Initially, Caldera was designed as a Rollup deployment platform that can launch high-performance, customizable, and application-specific rollups using the Arbitrum Nitro, Optimism Bedrock, zkSync ZK Stack, and Polygon CDK frameworks. Through Caldera, projects can easily deploy Rollups without the support of a technical team. According to official information, the number of Rollups based on Caldera has exceeded 60.

While these Rollups are numerous, they are scattered and their liquidity is isolated, resulting in inconsistent user experience and application efficiency. To address this issue, Caldera plans to build a Metalayer after a recent successful funding round, aiming to create a barrier-free network. This is an innovative interoperability layer with the goal of unifying these disparate Rollups, breaking the liquidity silos, and uniting the entire fragmented Layer 2 ecosystem.

II. Caldera Funding Background

Caldera has been receiving continuous attention from the capital markets, as evidenced by its recent completion of a $15 million Series A funding round. The lead investor is Founders Fund, with participation from other investment firms such as Dragonfly, Sequoia Capital, Arkstream Capital, Lattice, reflecting broad market confidence in Caldera. Last year, Caldera raised $10 million, and with the new round of funding, its total funding has reached $25 million, providing strong support for its technological development and ecosystem building.

III. Caldera's Rollup Ecosystem and Growth

The Rollup ecosystem is a collection based on Ethereum Layer 2 scaling solutions, with the core aim of increasing network throughput, reducing transaction fees, while not compromising the security and decentralization of the blockchain network. This ecosystem includes various types of Rollup technologies, such as Optimistic Rollup and ZK Rollup, which batch a large number of transactions together, only interacting with the Ethereum mainnet when necessary, significantly improving transaction processing speed and reducing costs.

The adoption of Rollup technology has significantly increased TPS (transactions per second), reduced Gas fees expenditure, and ensured security and network decentralization, allowing DeFi users to more efficiently manage assets, engage in lending and trading; meanwhile, developers can leverage the Rollup platform to develop and deploy dApps (decentralized applications) at lower costs and higher efficiency; for the average user, the Rollup ecosystem can help users enjoy a more streamlined experience similar to centralized services when using decentralized applications, such as reducing transaction confirmation wait times while ensuring asset security.

Launched in 2022, Caldera has now become one of the world's fastest-growing Rollup ecosystems, empowering Web3 teams to customize and launch over 60 high-performance Rollups covering multiple application categories. Currently, the Caldera ecosystem includes 1.7 million unique wallets, holding over $800 million in total value locked (TVL) and has processed over 60 million transactions. Some noteworthy chains include Manta Pacific, inEVM (Injective), ApeChain, Zero Network (Zerion), among others. Currently, inEVM has surpassed 800 million total transactions, with over 3 million transactions in the past week; meanwhile, ApeChain is set to launch its testnet soon.

4. Future Outlook of Caldera

According to the official website's roadmap, Caldera's zkSync mainnet and Polygon CDK testnet have already launched, and the next step will be the release of the Polygon CDK mainnet and self-service mainnet. Additionally, to get an early look at the user experience of Web3 dApps built on the Metalayer, Caldera has established the first NFT minting factory on all Caldera chains, allowing users to mint the first NFT on the Caldera Metalayer by visiting metalayer.caldera.xyz.

As Caldera continues to advance its Metalayer project, we have reason to believe it will play a significant role in the development of Web3. By achieving seamless connectivity between Layer 2 and Layer 3, Caldera has not only tackled technical challenges but also fostered collaboration and innovation across the industry. In the future, we look forward to seeing more projects and teams adopt Caldera's Metalayer to collectively build a truly interconnected blockchain network.
