CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721,SPLtokens with custom minting, vesting, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, supply chain tracking, and verifiable credentials.
From initial concept to mainnet deployment, we ensure your contracts are secure, scalable, and audit-ready in as little as 2-4 weeks.

TANGIBLE RESULTS
Business Outcomes with Sovereign Rollups
Sovereign rollups are more than a technical architecture; they are a strategic business asset. We deliver production-ready rollups that directly impact your bottom line and competitive edge.
01
Complete Data Control & Sovereignty
Retain full ownership of your transaction data and state, eliminating reliance on external sequencers. This ensures censorship resistance and provides a foundation for proprietary data monetization strategies.

Sequencer Dependence
02
Radically Lower Transaction Costs
Execute thousands of transactions off-chain and settle in a single batch on the base layer. We architect for sub-cent fees, enabling microtransactions and new economic models for your dApp.

Architecture Comparison
Sovereign Rollup vs. Smart Contracts vs. Shared L2
A technical breakdown of the core differences between blockchain scaling architectures to help you select the optimal foundation for your application.
| Architecture | Sovereign Rollup | Smart Contracts (L1) | Shared L2 (e.g., Arbitrum, Optimism) |
|---|---|---|---|
Data Availability & Settlement | Sovereign chain (your own), posts data to any DA layer | Base layer (e.g., Ethereum) | Parent L1 (e.g., Ethereum) |
Execution Environment Control | Full control (any VM, custom logic) | Limited by host L1 (e.g., EVM) | Limited by L2 provider's VM |
Sequencer & Block Producer | You operate it | L1 validators/miners | L2 provider operates it |
Upgrade & Fork Flexibility | Full autonomy; instant upgrades possible | Governance or immutable; upgrades are hard forks | Contingent on L2 provider's governance/timeline |
Time to Finality | < 2 seconds (sovereign) | ~12 seconds (Ethereum) | ~1-2 minutes (to L1) |
Throughput (TPS) | 10,000+ (theoretical, based on config) | ~15-30 (Ethereum) | 2,000-4,000 (typical) |
Gas Fee Recipient | Your protocol treasury | L1 validators | L2 sequencer (provider) |
Development & Deployment Time | 4-8 weeks (with Chainscore) | 2-4 weeks | 1-2 weeks |
Typical Cost (Year 1) | $150K-$500K (development & ops) | $50K-$200K (gas, dev) | $100K-$300K (gas, potential revenue share) |
Ideal Use Case | High-throughput apps, appchains, novel VMs, maximal sovereignty | Simple dApps, value storage, where L1 security is paramount | General-purpose dApps needing scale without operational overhead |

PROVEN METHODOLOGY
Our Development Process
A systematic, security-first approach to deliver a production-ready sovereign rollup in 8-12 weeks. We focus on reducing your time-to-market while ensuring enterprise-grade reliability and sovereignty.
01
Architecture & Design
We define your rollup's data availability layer, settlement mechanism, and execution environment. We select the optimal stack (OP Stack, Arbitrum Nitro, Polygon CDK, zkSync ZK Stack) based on your throughput, cost, and decentralization requirements.

Technical & Commercial Insights
Sovereign Rollup Development FAQs
Get clear answers to the most common questions CTOs and founders ask when evaluating a sovereign rollup development partner.
Our standard sovereign rollup deployment takes 2-4 weeks from kickoff to mainnet launch for a typical L2. This includes core infrastructure setup, custom bridge/sequencer logic, and basic dApp integration. Complex ecosystems with custom fraud proofs or specialized data availability layers may extend to 6-8 weeks. We provide a detailed, phased project plan during the initial technical scoping.
