Blockchain · Service Rollup and appchain development
Layer-2 rollups and appchains on OP Stack, Arbitrum Orbit, ZK Stack or Polygon CDK: sequencer, data availability, bridge, explorer and operations.
In short
A rollup is a blockchain that executes transactions off Ethereum and posts the data and proofs back to it, inheriting much of Ethereum's security at lower cost. An appchain is a chain dedicated to one application or ecosystem. Frameworks such as OP Stack, Arbitrum Orbit, ZK Stack and Polygon CDK make launching one practical — but most applications do not need their own chain, and we will say so.

Signs this is the right service
- Your application needs throughput, fees or customisation a shared chain cannot give.
- You want your own gas token, sequencer revenue or permissioned participation.
- An ecosystem of applications will build on your chain.
- You need predictable fees that do not depend on activity elsewhere.
What you get
Framework choice
Optimistic or zero-knowledge rollup, and which stack — chosen for proof time, cost and ecosystem.
Data availability
Ethereum blobs or an alternative data-availability layer, with the security trade-off explained.
Sequencer and nodes
Sequencer, RPC nodes and archive nodes deployed with monitoring and failover.
Bridge and tooling
The canonical bridge, a block explorer, faucets and developer documentation.
Operations
Upgrade procedures, incident runbooks and on-call for the chain.
The process
- 01
Should you build a chain?
An honest comparison against deploying on an existing layer-2.
- 02
Choose the stack
Framework, data availability and whether to use a rollup-as-a-service provider.
- 03
Testnet
A public testnet with the bridge, explorer and tooling in place.
- 04
Mainnet and operations
Launch with monitoring, then ongoing operation or handover.

Rollups & appchains: common questions
Do we need our own chain?
- Usually not. Deploying on an existing layer-2 is cheaper and simpler. A dedicated chain makes sense when you need custom fees, throughput, gas token or permissions — or you are building an ecosystem.
Optimistic or ZK rollup?
- Optimistic rollups are mature and simpler, with a challenge period before withdrawals finalise on Ethereum. ZK rollups prove correctness with cryptography and finalise faster, with heavier infrastructure.
What does it cost to run?
- Mainly sequencer and node hosting plus the cost of posting data to Ethereum or another data-availability layer. We estimate both before you commit.
What is rollup-as-a-service?
- Providers that deploy and operate rollups for you. They can shorten the path to launch; we help you decide whether one fits.
