Thread444 words
Explains Caldera as a stack-agnostic RaaS supporting OP Stack, Arbitrum Nitro and ZK Stack, with a choice of settlement and DA layers, integrated tooling and the Hyperlane-powered Metalayer making its chains composable.
Key claims
Over $420M TVL across dozens of chains, 12M users and 486M transactions
Supports OP Stack, Arbitrum Nitro and ZK Stack
DA options include Ethereum blobs, Celestia, EigenDA and Avail
Over 420M in TVL across dozens of (app)chains that collectively count 12M users and 486M transactions.
A multichain ecosystem that allows anyone to launch modular rollups in a matter of minutes.

Caldera is built around a stack-agnostic Rollup-as-a-Service (RaaS) framework that enables devs to focus only on app logic and UX, with all infra-related complexity being abstracted entirely.
To maximize customizability, Caldera chains are fully modular, separating the execution layer from the data availability layer.
This architectural choice provides developers unmatched freedom and flexibility, allowing them to tailor the blockchain infra precisely to their application's unique needs.
More specifically, Caldera supports all the leading rollup stacks (optimistic and ZK):
- OP Stack
- Arbitrum Nitro
- ZK Stack
It allows devs to launch their rollup on their preferred EVM settlement layer, with options including, but not limited to:
- Ethereum
- Arbitrum
- Base
This infra-level customizability means that developers can leverage the security, liquidity, and existing ecosystem of their preferred blockchain while optimizing for performance, cost efficiency, or other specific UX-related requirements.
Additionally, developers can also select specialized data availability layers such as:
- Ethereum (blobs)
- Celestia
- Eigenlayer's EigenDA
- Avail
High performance DA solutions like @celestia, @eigen_da or @AvailProject improve scalability, reduce operational cost of running the chain, and significantly enhance the overall performance of the apps.
Beyond the modular approach to network architecture, Caldera provides an extensive suite of integrated tools & infra designed to streamline app development.
This includes:
- High-Level APIs: Robust support for standard tokens (ERC20, ERC721), simplifying token management & integration.
- JSON-RPC Nodes: Reliable endpoints ensuring seamless interaction with the blockchain.
- Bridging SDK: Out-of-the-box, intent-based cross-chain interop framework (Metalayer).
- Graph Indexing: Built-in indexing capabilities facilitating rapid querying and analytics.
- Oracles: Native support for reliable data feeds essential for dynamic apps with data dependencies.
- Gnosis Safe: Pre-integrated secure multisig solutions for enhanced operational security.
These comprehensive tooling integrations eliminate much of the traditional complexity associated with deploying and maintaining auxiliary infra, allowing developers to focus their efforts exclusively on creating exceptional user experiences.
A key differentiator in this context is also the Metalayer, a robust, intent-based message-passing mechanism powered by @hyperlane, that is automatically deployed across every Caldera rollup.
This turns the market-leading RaaS provider into a fully composable appchain ecosystem with dozens of chains that are home to millions of users and hundreds of millions in TVL, and where launching your own chain is just a few clicks away.
