We architect and deploy custom smart contracts that power your dApp's core logic. Every contract is built with security-first principles, utilizing battle-tested libraries like OpenZeppelin and following EIP standards for ERC-20, ERC-721, and beyond.

The Cost of Getting It Wrong
Advised Migration vs. Ad-Hoc Attempt
Migrating smart contracts and assets across rollups is a complex, high-stakes operation. This table contrasts the outcomes of a structured, expert-led migration with the risks of an unplanned, in-house attempt.
| Migration Factor | Ad-Hoc In-House Attempt | Chainscore Advised Migration |
|---|---|---|
Time to Successful Migration | 3-6+ months (unpredictable) | 4-8 weeks (guaranteed timeline) |
Security & Fund Risk | High (unaudited bridge logic, manual steps) | Negligible (audited patterns, automated tooling) |
Team Resource Drain | 2-3 senior devs full-time | Your team focuses on core product |
Post-Migration Issues | Likely (state inconsistencies, user support burden) | Rare (comprehensive testing & monitoring) |
Total Project Cost | $150K-$400K+ (dev time + incidents) | $50K-$120K (fixed-fee or milestone) |
Guaranteed Success SLA | ||
Post-Migration Support | Your responsibility | 30-day included support & monitoring |

STRUCTURED MIGRATION
Our Phased Delivery Process
A systematic, low-risk approach to moving your dApp or assets between rollups. We deconstruct complexity into clear, executable phases with defined deliverables and success criteria at each stage.
01
Phase 1: Discovery & Strategy
We conduct a technical deep-dive to map your current architecture, token standards, and user flows. The output is a detailed migration blueprint with cost analysis, risk assessment, and a recommended target rollup stack (ZK-Rollup, Optimistic Rollup, etc.).

Phase 2: Smart Contract & Bridge Architecture
Design and specification of the core migration infrastructure. We architect secure, gas-optimized bridge contracts, asset wrappers, and any required custom logic (e.g., for state migration) using battle-tested patterns from OpenZeppelin and Chainlink CCIP.

Technical & Commercial Questions
Cross-Rollup Migration FAQs
Common questions from CTOs and technical founders evaluating migration partners. Based on insights from 20+ successful rollup migrations.
A standard migration for a DeFi protocol or NFT project takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture review and planning, 2-4 weeks for development and testing, and 1 week for final audits and deployment. Complex protocols with custom bridges or novel tokenomics may extend to 12 weeks. We provide a detailed, phase-gated project plan in the first week.
