PROVEN FRAMEWORK
Our Integration Methodology
We deploy a structured, four-phase approach to ensure your legacy banking systems integrate with blockchain securely, compliantly, and with minimal operational disruption.
01
Discovery & Architecture Design
We conduct a deep-dive analysis of your existing core banking, payments, and compliance systems to design a future-proof integration architecture. This includes selecting optimal protocols (e.g., Hyperledger Besu, Polygon Supernets) and defining clear data flows.

Common Questions on Banking-Blockchain Integration
Get clear, direct answers to the most frequent questions CTOs and product leads ask when integrating blockchain with legacy banking systems.
A standard integration of a new blockchain-based payment rail or asset tokenization module takes 8-12 weeks from kickoff to production. This includes a 2-week discovery phase, 4-6 weeks of development and integration, and 2-4 weeks of testing, security review, and deployment. More complex transformations, like a full ledger overhaul, require a phased approach over 4-6 months.
