Caldera and Conduit describe managed chains with different platform integrations. Gelato describes rollups alongside smart-wallet and gas-sponsorship tools. If the buyer's problem includes user onboarding and transaction UX after launch, compare those adjoining services and who operates them; this is separate from choosing a rollup framework or DA layer.
What happens after the chain launches?
Launching a dedicated rollup or appchain is not just a developer decision. It changes how users bridge assets, how liquidity forms, how the product is monitored, how fees are managed, how upgrades happen and how security assumptions are explained.
Caldera, Conduit and Gelato all describe rollup infrastructure. This comparison concentrates on the work around launch: connecting users, sponsoring transactions and operating the chain once people rely on it.
For framework, settlement, DA and upgrade-control choices, see our separate Caldera, Conduit and AltLayer comparison. Keeping those decisions distinct avoids treating two different procurement tasks as one ranking.
Quick Comparison
| Provider | Workflow to test | Open question | Buyer should verify |
|---|---|---|---|
| Caldera | Teams that want custom rollups and interoperability across a rollup ecosystem | Teams that only need a simple deployment on an existing L2 | Rollup stack, Metalayer routes, bridge assumptions, app support, chain launch process |
| Conduit | Teams that want complete chain infrastructure with rollups, RPC, indexing and marketplace tooling | Teams that want only one narrow module without a broader platform | Supported stacks, node uptime, indexing, marketplace apps, data availability, sequencer model |
| Gelato | Teams that need rollups alongside smart wallets and sponsored transactions | Which wallet and gas services are included in the proposed deployment? | Rollup support, paymaster/bundler scope, wallet integration, monitoring and pricing |
Short Answer
Test Caldera if interoperability and custom rollup deployment are central to the strategy.
Test Conduit if you need a chain platform with RPC and other operating services in one proposal.
Test Gelato if the chain launch and user experience both require rollups, smart wallets and gas sponsorship.
Caldera: Best for Custom Rollups and Interoperability
Caldera is known for Rollup-as-a-Service and its Metalayer interoperability work. Its documentation describes Metalayer as an interoperability system for a rollup-centric world, with bridge aggregation, omnichain tokens and shared liquidity across connected networks. Its Rollup Engine materials describe app-specific rollups deployed across frameworks such as Arbitrum Nitro, Optimism Bedrock, ZK Stack and Polygon CDK.
Caldera may fit:
- applications that want a dedicated rollup
- gaming, social or DeFi products needing custom execution
- projects that care about day-one interoperability with other rollups
- ecosystems that want multiple chains connected through common infrastructure
- teams that want rollup launch support rather than internal chain operations
Caldera’s main value is not only launching a rollup. It is the combination of dedicated blockspace and an interoperability thesis through Metalayer. This matters because one of the biggest appchain problems is fragmentation. A chain with no liquidity, users or bridge clarity can become an island.
Questions to ask Caldera:
- Which rollup frameworks are supported for mainnet?
- What interoperability routes are available through Metalayer?
- Which bridges, solvers and message-passing systems are used?
- What is the sequencer model and upgrade process?
- What happens if we later migrate infrastructure or change stack choices?
- How are monitoring, incident response and chain support handled?
Conduit: Best for Complete Chain Infrastructure
Conduit positions itself as a complete chain infrastructure platform. Its public documentation describes rollup deployment, RPC nodes, indexing and marketplace tooling. Conduit also operates RPC infrastructure for many rollups and offers multi-chain access, autoscaling RPCs, performance monitoring and access controls.
Conduit may fit:
- teams launching production rollups
- apps that need RPC and indexing alongside the chain
- ecosystems that want tooling and integrations from a marketplace
- projects that want fewer infrastructure vendors
- teams that need operational dashboards and performance visibility
Conduit’s main strength is breadth across the chain operations layer. Instead of treating rollup launch, RPC and indexing as separate procurement decisions, Conduit gives buyers a platform view.
That breadth is useful, but buyers should still ask what is native to Conduit, what is partner-powered and what remains the buyer’s responsibility.
Questions to ask Conduit:
- Which rollup stacks are supported today?
- What RPC uptime and performance commitments apply?
- What indexing products are included or optional?
- Which marketplace apps are production-ready?
- How does pricing scale with chain usage?
- How are upgrades and emergency patches handled?
Gelato: rollups alongside wallet and gas tools
Gelato's current platform describes rollups alongside paymaster and bundler services for smart-wallet and gasless experiences. For a buyer, launching a chain is only one task. Users still need a way to create wallets and pay fees, and the operator needs to know which service owns each transaction step.
Gelato may fit:
- apps that need sponsored transactions
- products building smart-wallet onboarding
- consumer apps where gas abstraction matters
- teams that want rollup support plus wallet and gas tools
- projects that need developer infrastructure around the chain, not only chain launch
The key diligence point is scope. Buyers should clarify whether the proposal covers rollups, paymaster/bundler services, wallet tooling or a combination. Ask who owns failed user transactions and recovery when one service is unavailable.
Questions to ask Gelato:
- Which appchain stacks and deployment models are supported?
- Which paymaster, bundler and wallet tools are included?
- What support exists for monitoring and incident response?
- How does pricing work across chain operations and developer services?
- Which parts of the stack are Gelato-operated versus partner-operated?
- What happens if transaction volumes spike?
Buyer Framework: When to Launch an Appchain
Launch an appchain when:
- the application needs dedicated throughput
- fee predictability matters
- UX depends on custom gas or account rules
- the product needs custom compliance or permissioning
- the ecosystem wants its own app-specific economy
- existing networks create too much congestion or dependency
Do not launch an appchain when:
- the app has no liquidity strategy
- the team has no bridge and onboarding plan
- an existing L2 is sufficient
- the budget cannot support chain operations
- the legal and compliance model is unclear
- the user base does not care about dedicated infrastructure
The Most Important Questions
Before choosing a RaaS provider, answer these questions internally:
- Why do we need our own chain?
- Which assets must move in and out?
- Where does liquidity come from?
- Who operates the sequencer?
- What bridge assumptions are acceptable?
- What is the data availability strategy?
- What happens during downtime?
- Who handles upgrades?
- What tools do developers and users need on day one?
Which Provider Should You Shortlist?
Shortlist Caldera if rollup interoperability is central to the application plan.
Shortlist Conduit if chain operations, RPC and additional tooling need one operating plan.
Shortlist Gelato if rollups, smart-wallet onboarding and sponsored transactions need to fit together.
For most buyers, the right shortlist is not one vendor. It is one RaaS provider plus bridge, security, oracle, RPC, data availability and monitoring diligence.

FAQ
Which is better: Caldera, Conduit or Gelato?
There is no universal winner. Compare the chain launch scope and the wallet, gas and operations services you actually need. Ask which products are included in the proposed contract.
What is Rollup-as-a-Service?
Rollup-as-a-Service helps teams launch and operate dedicated rollups without building every sequencer, node, bridge, explorer, deployment and monitoring component internally.
When should a project launch an appchain?
An appchain may make sense when an application needs dedicated throughput, custom economics, predictable fees, specialized compliance, branded infrastructure or control over the execution environment.
What are the risks of launching an appchain?
Risks include fragmented liquidity, bridge dependency, sequencer centralization, security assumptions, infrastructure cost, monitoring burden and ecosystem distribution.
Does RaaS remove the need for blockchain engineers?
No. RaaS reduces infrastructure work, but teams still need protocol, security, DevOps, smart contract, compliance and product expertise.
What should buyers ask a RaaS provider?
Ask about supported stacks, data availability, settlement chain, sequencer model, bridge design, monitoring, upgrades, incident response, app ecosystem and exit options.
Is an appchain better than launching on an existing L2?
Not always. Existing L2s are usually faster and cheaper to start. Appchains are more relevant when the product needs dedicated blockspace, custom rules or infrastructure control.
Where can I compare more appchain vendors?
FluidRWA maintains a Rollup-as-a-Service and appchain provider directory for teams evaluating custom chain infrastructure.
