STRUCTURED & PREDICTABLE
Our Four-Phase Migration Process
A proven, methodical approach to migrate from legacy wallet systems (like centralized databases or insecure key management) to secure, scalable, and compliant blockchain infrastructure. We de-risk the transition with clear deliverables at each stage.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing wallet system, mapping user flows, transaction types, and security vulnerabilities. This phase delivers a detailed migration blueprint, including target blockchain selection (EVM, Solana, etc.), key management architecture (MPC, HSM, smart contract wallets), and a phased rollout plan.

Phase 2: Secure Key Migration
The most critical phase. We execute the secure transfer of private keys or seed phrases from legacy storage (files, databases) to your chosen modern custody solution. This includes implementing Multi-Party Computation (MPC) wallets, hardware security modules (HSM), or smart contract-based accounts with zero single points of failure.

Phase 3: Integration & Testing
We integrate the new wallet infrastructure with your application's backend and frontend. This includes developing secure APIs for transaction signing, balance queries, and user onboarding. Every component undergoes rigorous testing: unit, integration, and a full-scale security audit by a third-party firm like CertiK or OpenZeppelin.

Technical & Process Questions
Legacy Wallet Migration FAQs
Answers to the most common technical and operational questions about migrating from legacy wallet systems to modern MPC or smart contract architectures.
A standard migration project takes 4-8 weeks from kickoff to production deployment. This includes a 1-week discovery/audit phase, 2-4 weeks for core development and testing, and 1-2 weeks for staging deployment and final security review. Complex multi-chain or high-TVL migrations may extend to 12 weeks. We provide a detailed Gantt chart in our project proposal.
