PROVEN PROCESS
Our Migration Methodology
A systematic, security-first approach to migrating your business logic to a new blockchain. We minimize risk and ensure zero downtime for your users.
01
Comprehensive Security Audit
We begin with a full audit of your existing contracts using static analysis and formal verification tools. This identifies vulnerabilities and ensures the new implementation is secure by design.

Choosing Your Infrastructure Model
Public vs. Private DeFi: A Strategic Comparison
Key differences between public and private smart contract architectures, and how Chainscore's migration service bridges the gap for institutional clients.
| Architectural Factor | Public DeFi (Open) | Private DeFi (Permissioned) | Chainscore Migration Service |
|---|---|---|---|
Transaction Privacy | Hybrid (ZK-Proofs/MPC) | ||
Regulatory Compliance | Complex | Designed for | Built-in KYC/AML Modules |
Smart Contract Audit | Optional (High Risk) | Mandatory | Full Audit + Formal Verification |
Settlement Finality | ~15 min (Ethereum) | < 2 seconds | Sub-Second with Custom Consensus |
Gas Cost Volatility | High & Unpredictable | Fixed/Controlled | Predictable Fee Structure |
Development Timeline | 4-8 weeks (Standard) | 6-12 months (Custom) | 8-12 weeks (Accelerated) |
Team Expertise Required | Solidity, MEV, Oracles | Consensus, Privacy, Infra | We Provide Full Stack Team |
Ongoing Infrastructure Cost | Variable (L1/L2 Fees) | High (Dedicated Validators) | Managed Service (SLA-Based) |
Time-to-Market for New Features | Slow (Governance Votes) | Slow (Internal Dev) | Fast (Modular Upgrades) |
Typical Initial Investment | $50K-$200K (Public) | $500K-$2M+ (Build) | $150K-$500K (Migrate) |

STRUCTURED MIGRATION
Our Phased Delivery Process
A predictable, low-risk methodology for migrating sensitive business logic to private smart contracts. We deliver production-ready code with zero downtime.
01
Discovery & Architecture
We conduct a full audit of your existing logic and data flows to design a secure, gas-efficient private contract architecture. This includes threat modeling and finalizing the technical stack (e.g., Aztec, Polygon Nightfall, Arbitrum Stylus).

Security Audit & Penetration Testing
Every contract undergoes a formal security review. We engage third-party auditors (e.g., Trail of Bits, Quantstamp) and conduct internal penetration testing focused on privacy leakage and cryptographic vulnerabilities.

Private Smart Contract Migration FAQs
Get clear answers on timelines, security, and process for migrating your protocol's core logic to a private, secure environment.
A standard migration for a protocol with 5-10 core contracts takes 2-4 weeks from audit review to mainnet deployment. This includes 1 week for architecture planning and environment setup, 1-2 weeks for the migration and integration build, and 1 week for internal QA and client acceptance testing. Complex DeFi protocols with 20+ interdependent contracts can take 6-8 weeks.
