In the field of Blockchain, Layer-2 technology was once regarded as the ultimate solution for Ethereum's scalability. However, the reality is less than satisfactory: issues such as too many chains, poor interoperability, fragmented Liquidity, and high development thresholds have gradually emerged, becoming potential obstacles to the development of the Blockchain world.

In this context, Caldera has emerged, bringing a breath of fresh air to the Layer-2 ecosystem. Caldera is not just another ordinary Rollup solution, but puts into practice the innovative concept of 'Rollup as a Service' (RaaS). Its goals are clear and ambitious: to enable anyone to easily build and operate their own high-performance blockchain, while ensuring interoperability between chains and breaking the island effect.

Caldera was launched in 2023, with its core positioning as 'Rollup as a Service'. This service model encapsulates complex layer-2 network technology into a user-friendly self-service platform. Developers can quickly deploy their own high-performance Rollup chain with simple operations. This convenience particularly attracts many development teams with a Web2 background, allowing them to avoid in-depth learning of blockchain development technology and not requiring significant investment to build a professional technical team.

As of July 2025, Caldera is experiencing strong momentum. The platform has attracted 1.8 million unique wallet users, with a total locked value (TVL) exceeding $550 million, and a cumulative transaction volume surpassing 80 million, demonstrating remarkable growth potential.

However, Caldera's ambitions go far beyond this. Its truly disruptive innovation lies in the introduction of the Metalayer protocol. The Rollup engine provided by Caldera not only allows users to quickly deploy their own Layer-2 networks, but more importantly, it opens up new possibilities for addressing interoperability challenges within the Layer-2 ecosystem.

Through the Metalayer protocol, Caldera aims to build a more open and interconnected Layer-2 ecosystem. This not only helps improve the synergy between various Layer-2 networks but also provides users with a smoother and more integrated Blockchain experience.

The emergence of Caldera marks the development of Layer-2 technology towards a more mature, user-friendly, and interoperable direction. It not only simplifies the deployment process of blockchain networks but also provides innovative solutions to many challenges faced by the current Layer-2 ecosystem. With the continuous evolution of technology, Caldera is expected to play a key role in promoting the large-scale adoption of blockchain.
