Overview
Layer 2 networks scale Ethereum by executing transactions off-chain and posting data or proofs to Ethereum. We help teams launch and operate L2s using established rollup stacks — configuring sequencers, bridges, data availability, fee parameters, explorers and RPC infrastructure — and build custom components where differentiation matters.
Common use cases
- Branded L2An L2 for a large application or ecosystem.
- Enterprise L2Controlled L2 with Ethereum settlement.
- Gaming L2High-throughput chains for games.
- Payments L2Low-cost settlement for payments.
Quick answers
Layer 2 Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is layer 2 development?
- Layer 2 scaling solutions on Ethereum — rollup deployment, sequencers, bridges, fee economics and ecosystem tooling.
- Who is it for?
- Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
- What does Shivacha provide?
- Rollup stack deployment
- Sequencer operations
- Bridge setup
- Data availability
- Fee economics
- Ecosystem tooling
- Which technologies are used?
- Arbitrum, Optimism, Base, Ethereum, Solana, Rust — chosen to fit your stack and constraints.
- How does the process work?
- Requirements → Design & specification → Implementation → Testnets → Mainnet operations.
- What affects the cost?
- Contract complexity and number of chains
- Custody and wallet model
- Independent audit scope
- Indexing, analytics and back-office tooling
- Compliance integrations (KYC, AML, Travel Rule)
- Upgradeability and governance requirements
- How long does it take?
- A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.
- How do I get started?

Capabilities
What we deliver
Rollup stack deployment
Configuration of established frameworks.
Sequencer operations
Operation, redundancy and monitoring.
Bridge setup
Canonical bridge and withdrawal flows.
Data availability
DA options and cost trade-offs.
Fee economics
Gas pricing and revenue modelling.
Ecosystem tooling
Explorers, RPC and developer docs.
Architecture
Engineered right from day one
The layers we typically design for protocol & blockchain infrastructure, adapted to your stack and partners.
- Framework vs customEstablished rollup and appchain frameworks where possible; custom only where justified.
- Bridge riskBridges are high-value targets; designs minimise trust and include rate limits and pause controls.
- Operational resilienceRedundant infrastructure, key management and incident runbooks.
- Upgrade governanceClear, transparent upgrade paths with timelocks.
Delivery
How an engagement runs
- 1
Requirements
Throughput, latency, finality, decentralisation and cost targets.
- 2
Design & specification
Protocol specification, threat model and economic analysis.
- 3
Implementation
Client, contracts and tooling with extensive testing.
- 4
Testnets
Staged devnets and public testnets with monitoring and chaos testing.
- 5
Mainnet operations
Launch, validator onboarding, monitoring and upgrade processes.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Specification first
Roles, invariants and threat model documented before code.
Adversarial testing
Fuzz, invariant and fork tests plus static analysis on every change.
Key management
Admin keys in multisig or MPC with timelocks on sensitive actions.
Independent audit
Code prepared for — and we recommend — an external audit before mainnet value.

Ethereum mainnet offers the deepest security and liquidity; Polygon offers lower fees and fast confirmation. The right choice depends on value at risk, users and ecosystem.

Frequently asked questions
Optimistic or zero-knowledge rollup?
Optimistic rollups are mature and EVM-equivalent with longer withdrawal times; ZK rollups offer faster finality with more complex proving. The choice depends on your priorities.
Who operates the sequencer?
Initially often the launching team; decentralisation of sequencing can be planned in phases.
Should we build an appchain or deploy on an existing network?
Most applications are better served by deploying on an existing Layer 1 or Layer 2. An appchain or rollup makes sense when you need custom execution, dedicated throughput, fee control or specific governance — and can support the operational overhead.
Do you run node infrastructure?
We design, deploy and automate node, RPC and validator infrastructure in your cloud accounts, with monitoring and alerting, and can operate it under a managed services agreement.
