FROM LEGACY TO LEADING-EDGE
Business Outcomes of a Modernized Architecture
Migrating your smart contracts isn't just a technical upgrade—it's a strategic business decision. Our migration service delivers measurable improvements in performance, security, and operational efficiency.
01
Enhanced Security & Reduced Risk
We migrate contracts to modern Solidity 0.8+ with OpenZeppelin libraries, eliminating known vulnerabilities from older versions. Every migrated contract undergoes a formal security review, significantly reducing the risk of exploits and protecting your assets.

STRUCTURED APPROACH
Our 4-Phase Migration Process
A proven, risk-mitigated framework for migrating legacy financial logic to secure, audited smart contracts. We ensure zero business logic errors and minimal operational disruption.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing system, mapping all business rules, state transitions, and dependencies. This phase delivers a detailed migration blueprint, gas cost analysis, and a security-first target architecture on EVM-compatible chains (Ethereum, Arbitrum, Polygon).

Technical & Process Questions
Smart Contract Migration FAQs
Answers to the most common questions from CTOs and technical leads planning a migration from legacy smart contracts or monolithic systems to modern, secure, and scalable architectures.
Our standard migration timeline is 4-8 weeks, from audit to mainnet deployment. A typical breakdown includes:
- Week 1-2: Comprehensive audit of legacy code and design of new architecture.
- Week 3-5: Development, unit testing, and deployment to a testnet.
- Week 6-7: Security audit by a third-party firm and integration testing.
- Week 8: Final deployment and verification on mainnet. Complex protocols with custom oracles or cross-chain logic may extend this timeline, which we define in a fixed-scope proposal.
