PROVEN PROCESS
Our Migration Methodology
A systematic, security-first approach to moving your protocol's logic and assets with zero downtime and guaranteed data integrity.
01
Comprehensive Pre-Migration Audit
We conduct a full security and logic review of your existing contracts, identifying upgrade risks, gas inefficiencies, and state dependencies before a single line of new code is written.

State & Logic Decoupling
Architect the new contract system using upgradeable patterns (UUPS/Transparent Proxy) to separate business logic from stored data, enabling future upgrades without another complex migration.

Risk & Cost Analysis
In-House vs. Chainscore Managed Migration
A detailed comparison of the time, cost, and risk profile of managing a stealth contract migration internally versus leveraging Chainscore's expert-managed service.
| Key Factor | In-House Development | Chainscore Managed Service |
|---|---|---|
Time to Completion | 3-6 months | 4-8 weeks |
Security & Audit Risk | High (unaudited, custom code) | Low (pre-audited patterns, formal verification) |
Upfront Development Cost | $150K - $400K+ | $50K - $150K |
Ongoing Maintenance Burden | Your team (full-time) | Optional SLA (we manage it) |
Protocol & Tooling Expertise | Requires hiring/ramp-up | Included (EVM, Solidity, Foundry experts) |
Emergency Response SLA | None (internal on-call) | 24/7 with 4-hour response |
Post-Migration Monitoring | Manual, ad-hoc | Automated, 30-day included |
Total Year 1 Cost (Est.) | $200K - $500K+ | $75K - $200K |

A PROVEN 4-STEP FRAMEWORK
The Chainscore Migration Process
Our structured, security-first approach ensures your contract migration is seamless, secure, and executed with zero downtime. We handle the technical complexity so you can focus on your product.
01
1. Comprehensive Audit & Strategy
We perform a deep-dive analysis of your existing smart contracts, tokenomics, and dependencies to build a risk-mitigated migration blueprint. This includes identifying upgrade patterns, security vulnerabilities, and gas optimization opportunities.

CORE SERVICE
Custom Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from concept to deployment.
We architect and deploy production-grade Solidity and Rust contracts for DeFi, NFTs, and enterprise applications. Our process delivers secure, gas-optimized code with a 2-4 week MVP timeline.
We don't just write code; we engineer systems that are secure by design and built to scale.
- End-to-End Development: From technical specification and
OpenZeppelin-based architecture to deployment and verification on mainnet. - Security-First Approach: All contracts undergo internal audits and formal verification before client review.
- Protocol Integration: Seamless compatibility with
Uniswap V3,AAVE, and other major DeFi primitives.
Technical & Process Questions
Stealth Migration FAQs
Get clear answers on our methodology, security, and timelines for seamless, secure smart contract migrations.
Our process follows a structured 4-phase approach: 1) Discovery & Planning (1 week), where we audit your existing contracts and design the migration strategy. 2) Development & Testing (2-3 weeks), where we build and rigorously test the new contracts and migration scripts. 3) Security Audit & Dry Run (1 week), including an internal review and a staging deployment. 4) Production Deployment & Monitoring (1-2 days). Most standard migrations are completed within 4-6 weeks from kickoff.
