overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From a 2-week MVP to a full protocol suite, we deliver contracts that are gas-optimized, upgradeable, and secure by design.
- Custom Logic: DeFi primitives (AMMs, lending/borrowing), NFT collections with dynamic traits, DAO governance modules.
- Security First: Multi-stage review process, integration with
SlitherandMythX, and preparation for third-party audits. - Full Lifecycle: Development, deployment, verification on Etherscan, and ongoing maintenance with versioning strategies.

Managed Migration vs. In-House Build
A detailed comparison of the total cost, risk, and time commitment required to migrate your application to a private rollup.
| Key Factor | In-House Build | Chainscore Managed Migration |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Upfront Capital Cost | $250K - $750K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited, custom risk) | Low (pre-audited patterns, formal verification) |
Core Team Requirements | 3-5 senior blockchain engineers | 1 technical lead for integration |
Ongoing Node Operations | Your team (24/7 DevOps) | Fully managed by Chainscore |
Protocol Upgrade Management | Manual, high-risk process | Automated, zero-downtime upgrades |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $120K - $300K |
Guaranteed Uptime SLA | None (self-managed) | 99.9% with financial backing |
Expert Support Access | Limited to hired team | Direct access to rollup core devs |

MINIMIZE RISK, MAXIMIZE UPTIME
Our Phased Migration Methodology
Our battle-tested, four-phase framework ensures your rollup migration is executed with surgical precision, guaranteeing zero downtime for users and eliminating data loss. We de-risk the most complex infrastructure upgrades.
01
Phase 1: Discovery & Architecture
We conduct a full audit of your current state, mapping all smart contracts, dependencies, and data flows. This phase delivers a detailed migration blueprint and risk assessment, identifying critical paths and potential bottlenecks before a single line of code is changed.

Phase 2: Parallel Testnet Deployment
We deploy and rigorously test the new rollup stack on a dedicated testnet mirroring mainnet conditions. This includes load testing, state transition validation, and full regression suites to ensure functional parity and performance targets are met.

Technical & Commercial Considerations
Private Rollup Migration FAQs
Answers to the most common questions from CTOs and technical founders about migrating to a private rollup. Based on our experience delivering 50+ high-value blockchain infrastructure projects.
A standard migration from a public L1 or existing L2 to a private rollup takes 2-4 weeks from kickoff to mainnet deployment. This includes environment setup, smart contract porting, sequencer configuration, and final security audit. Complex protocols with custom precompiles or intricate state management may extend to 6-8 weeks. We provide a detailed, phase-gated project plan on day one.
