A SYSTEMATIC APPROACH
Our Porting Methodology: Precision, Not Just Translation
Moving code between languages is more than syntax. Our battle-tested methodology ensures functional equivalence, security, and optimal performance for your new blockchain environment.
01
Comprehensive Audit & Analysis
We begin with a deep audit of your existing smart contracts, mapping all business logic, dependencies, and security patterns. This creates a deterministic specification for the port, eliminating ambiguity and risk.

Logic Coverage
O(n) Audit
Gas Analysis
02
Semantic-Preserving Translation
Our engineers translate the core semantics, not just keywords. We ensure state variables, function behaviors, and access controls are perfectly mirrored in the target language (e.g., Solidity → Move, Vyper → Cairo).
1:1
Behavioral Match
Zero Drift
State Integrity
03
Target-Language Optimization
We leverage native features of the destination chain—like storage models, cryptographic primitives, and gas structures—to rebuild your contract for maximum efficiency and lower operational costs.

04
Rigorous Verification & Testing
Every port undergoes property-based testing, differential fuzzing against the original contract, and formal verification where applicable to guarantee functional equivalence and security.

05
Security Audit & Best Practices
The final code is audited against target-chain-specific vulnerabilities and industry standards (e.g., SCVS). We implement upgrade patterns and disaster recovery logic tailored to the new ecosystem.

Common Porting Paths & Key Considerations
Compare the time, cost, and risk of building a porting team in-house versus partnering with Chainscore's specialized engineers.
| Key Factor | Build In-House Team | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Upfront Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited, custom tooling) | Low (pre-audited patterns, formal verification) |
Team Expertise Required | Senior Solidity/Rust/Haskell devs | Our dedicated porting specialists |
Ongoing Maintenance | Your engineering team (2+ FTEs) | Optional SLA with 24/7 support |
Risk of Protocol Incompatibility | High (manual testing) | Mitigated (proven test suites) |
Access to Latest Optimizations | Delayed (internal R&D) | Immediate (continuous protocol updates) |
Typical Total Cost (Year 1) | $500K - $1.2M+ | $80K - $200K |

Our 4-Phase Delivery Process
We de-risk your language migration with a structured, milestone-driven approach. Each phase delivers verified, production-ready artifacts, ensuring your project stays on schedule and within budget.
01
Phase 1: Architecture & Specification
We perform a comprehensive audit of your existing codebase to define the target architecture, map all business logic, and create a detailed technical specification. This blueprint ensures zero feature loss and identifies optimization opportunities from day one.

ERC-721A,ERC-1155implementations for marketplaces, gaming, and memberships. - Enterprise Logic: Custom business logic, multi-signature wallets, and governance systems for DAOs.
We focus on preventing exploits before they happen. Every contract undergoes internal review against common vulnerabilities (
reentrancy,overflow) and follows a formal verification methodology where applicable.
Typical deliverables: Fully documented Solidity 0.8.x/Vyper source code, a deployment script, and a technical specification document for your team or auditors. Get a production-ready MVP in as little as 3 weeks.
