PROVEN FRAMEWORK

Our Migration Methodology for Energy Platforms

A structured, risk-mitigated approach to modernize legacy energy trading, settlement, and certificate systems onto secure, transparent blockchain infrastructure.

01

Legacy System Audit & Architecture Mapping

We conduct a comprehensive analysis of your existing systems (e.g., ETRM, SCADA, settlement databases) to map data flows, business logic, and dependencies, creating a detailed migration blueprint.

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.
