Legacy System to Blockchain Provenance Migration
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
Deliver a secure, audited MVP in as little as 2 weeks with our proven development framework.
- Protocols & Standards:
ERC-20,ERC-721,ERC-1155,ERC-4626, and custom logic. - Security First: Built with OpenZeppelin libraries and formal verification practices.
- Full Lifecycle: From architecture and development to deployment, monitoring, and upgrade management.
Our Migration Methodology
We execute legacy data migration with surgical precision, ensuring zero data loss, full auditability, and immediate operational readiness for your blockchain-powered systems.
Discovery & Immutable Blueprint
We conduct a deep forensic audit of your existing data structures and business logic to create an immutable migration blueprint. This defines the on-chain data schema, mapping rules, and validation logic before a single line of code is written.
Secure Data Extraction & Validation
Our tooling performs cryptographically-verified extraction from legacy databases (SQL, NoSQL, APIs). Every record is hashed at source, creating a tamper-proof audit trail that proves data integrity from origin to blockchain.
Smart Contract Orchestration Layer
We deploy custom, audited smart contracts that act as the canonical settlement layer. These contracts manage the state transitions, enforce business rules, and provide permanent provenance for every migrated asset or record.
Atomic Batch Migration Execution
Migration is executed in verifiable atomic batches. Each batch is submitted as a transaction, providing on-chain proof of completion and allowing for real-time progress tracking and instant rollback capabilities if needed.
Verification & Reconciliation Dashboard
Gain immediate visibility with a custom dashboard that compares source system totals with on-chain state. Automated reconciliation reports provide cryptographic proof that every record was migrated correctly.
Post-Migration Support & Monitoring
We provide 30 days of post-migration monitoring and support, ensuring your new blockchain-provenance system operates flawlessly. This includes performance tuning, query optimization, and team training.
Business Outcomes: From Legacy Risk to Blockchain Trust
Our migration service delivers measurable improvements in security, efficiency, and transparency. We translate complex blockchain technology into clear business advantages for your operations and bottom line.
Immutable Audit Trail
Replace fragile, centralized logs with a cryptographically secure, tamper-proof ledger. Every transaction and data point is permanently recorded on-chain, providing a single source of truth for regulators, auditors, and partners.
Real-Time Provenance & Visibility
Enable stakeholders to verify asset origin, custody, and transaction history in real-time via public or permissioned explorers. Eliminate opaque supply chains and manual verification processes that delay operations.
Automated Compliance & Reporting
Embed regulatory logic directly into smart contracts. Automate KYC/AML checks, tax calculations, and reporting workflows to reduce manual overhead and ensure continuous compliance with evolving regulations.
Reduced Counterparty & Settlement Risk
Leverage atomic swaps and escrow contracts to enable trustless transactions. Funds and assets are exchanged simultaneously, eliminating the risk of one party defaulting after payment.
Operational Cost Reduction
Drastically cut costs associated with manual reconciliation, intermediary fees, fraud prevention, and maintaining legacy audit systems. Smart contracts automate enforcement, reducing administrative overhead.
Future-Proof Architecture
Our modular migration strategy builds on interoperable standards (ERC-20, ERC-721, ERC-1155). This creates a flexible foundation for integrating DeFi, NFTs, or tokenization without another costly platform overhaul.

Legacy System Migration: Key Questions
Common questions from CTOs and technical leads evaluating a blockchain migration partner.
Standard migrations from legacy databases (SQL, Oracle) to on-chain provenance take 3-6 weeks. This includes data schema mapping, smart contract development, and a phased rollout. Complex enterprise systems with multi-source integration may require 8-12 weeks. We provide a detailed project plan within the first week of engagement.
