Think of Ethereum scaling as road construction: in the past, each branch was built separately, with data and liquidity scattered everywhere. Caldera has changed the approach—first standardizing the engineering of new road construction with the Rollup Engine, and then connecting these roads into an interoperable elevated network with Metalayer. The former is responsible for quickly launching app-specific rollups, while the latter handles 'cross-rollup communication/asset transfer/shared liquidity.' Both official and academic materials identify these two components as Caldera's dual core.
The Rollup Engine's positioning is very similar to AWS on-chain: it turns sequencer, nodes, bridges, monitoring, and upgrade processes into configurable templates, allowing developers to almost instantly launch production networks with just a few clicks, and even automate operations via API. It transforms rollups from static chains into orchestratable infrastructure, accommodating different applications' throughput, cost, and finality requirements.
At the framework level, Caldera supports mainstream solutions like Arbitrum Nitro/Orbit, OP Stack, Polygon CDK, zkSync's ZK Stack, effectively packaging the development stack you're familiar with alongside a one-click deployable engineering solution; data availability can also connect to EigenDA / (optional) Celestia and other modules, allowing for flexible assembly based on budget and security assumptions.
The true network effect comes from Metalayer. It is Caldera's unified layer: new rollups are interconnected by default after launch, enabling message communication, asset transfer, and liquidity routing across rollups, avoiding the need for each chain to maintain separate bridges and routers. Binance Academy and several research institutions summarize it as the backbone layer for cross-rollup interoperability.
In terms of security, Metalayer's key contracts (such as MetalayerRouter/Fetcher) will undergo multiple audits by Halborn in 2025; Caldera has also disclosed a message layer based on Hyperlane and an intention-driven (solver-driven) bridging architecture, emphasizing control over cross-chain risks while remaining scalable.
Intuitive benefits for application developers:
Faster on-boarding: No need to write your own sequencer/bridge or set up monitoring;
Better connectivity: New chains come with their own lanes, reducing cold start costs;
Easier expansion: change framework, DA, and fee structures on demand, like swapping parts.
Caldera is not just about building more roads; it standardizes both road construction and connection—first, it builds roads quickly, then enables connectivity. This is the underlying logic of its transition from a RaaS platform to Rollups in the internet.
