Core Integration Capabilities
We deliver secure, compliant, and scalable infrastructure that bridges your legacy core banking systems with modern blockchain networks, enabling new revenue streams without operational disruption.
Secure API Gateway & Middleware
Deploy a dedicated, audited API layer that abstracts blockchain complexity. Our middleware handles transaction signing, nonce management, and gas optimization, providing a simple REST/GraphQL interface for your existing systems.
- Certified Security: Built with OpenZeppelin libraries and audited by third-party firms.
- Zero Trust Architecture: Enforces strict authentication and role-based access control.
Real-Time Settlement & Reconciliation
Replace batch processing with atomic, real-time settlement on-chain. Our integration engine automatically reconciles ledger entries between your core banking software (e.g., Temenos, Finacle) and blockchain state, eliminating manual errors.
- Sub-Second Finality: Leverage high-throughput chains like Solana or Polygon for instant settlement.
- Automated Audit Trail: Every transaction is immutably logged, simplifying compliance.
Regulatory Compliance Engine
Embedded compliance modules for KYC/AML, transaction monitoring, and regulatory reporting. Our system integrates with leading providers (Chainalysis, Elliptic) and enforces rules directly at the protocol level before settlement.
- Travel Rule (FATF) Ready: Built-in support for IVMS 101 data standards.
- Jurisdictional Rule Sets: Pre-configured policies for major financial hubs.
Custody & Key Management
Enterprise-grade custody solutions using MPC (Multi-Party Computation) or HSM integration. We provide flexible key management architectures—from fully managed to hybrid models—that meet your security and control requirements.
- No Single Point of Failure: Distributed key sharding with geographic separation.
- HSM Integration: Compatible with Thales, Utimaco, and AWS CloudHSM.
Multi-Chain Interoperability
Future-proof your integration with abstraction layers for Ethereum, Polygon, Solana, and other EVM/L1 networks. Issue assets and process payments on the optimal chain for cost and speed, all through a unified interface.
- Chain-Agnostic Routing: Intelligent routing based on fee, speed, and liquidity.
- Cross-Chain Messaging: Secure asset and data transfer via CCIP or Wormhole.
Disaster Recovery & Monitoring
Full observability stack with custom dashboards, alerting, and automated failover procedures. We ensure business continuity with hot-standby nodes, geographic redundancy, and 24/7 incident response.
- Real-Time Health Checks: Monitor node performance, block finality, and API endpoints.
- Guaranteed RTO/RPO: Define and meet specific recovery time and point objectives.
Business Outcomes for Banking Leaders
Our blockchain integration delivers concrete, auditable improvements to core banking operations, moving beyond proof-of-concept to production-grade financial infrastructure.
Real-Time Settlement & Reconciliation
Replace multi-day batch processing with atomic, on-chain settlement. Eliminate reconciliation costs and unlock 24/7 transaction finality for payments, securities, and cross-border transfers.
Programmable Compliance & Audit Trails
Embed regulatory logic directly into transaction flows with smart contracts. Create immutable, real-time audit trails that reduce manual reporting overhead and ensure continuous compliance (AML/KYC).
Reduced Operational & Intermediary Costs
Automate manual processes and disintermediate correspondent banks and clearinghouses. Significantly lower transaction fees, operational overhead, and capital requirements for liquidity provisioning.
New Revenue Streams & Product Innovation
Launch tokenized assets (bonds, funds, real estate), decentralized finance (DeFi) integrations, and blockchain-based trade finance platforms to serve next-generation clients and markets.
Enhanced Security & Fraud Prevention
Leverage cryptographic proofs and decentralized consensus to eliminate single points of failure. Our integrations are built with formal verification and undergo third-party audits (e.g., OpenZeppelin) for enterprise-grade security.
Future-Proof Interoperability
Build on agnostic architecture that connects private permissioned chains (Hyperledger Besu) with public networks (Ethereum, Polygon). Ensure seamless asset and data portability across the financial ecosystem.

Our Integration Methodology
Our battle-tested, four-phase methodology de-risks blockchain integration for financial institutions, ensuring regulatory compliance, security, and a seamless transition from legacy systems to modern, interoperable infrastructure.
Architecture & Compliance Audit
We conduct a comprehensive analysis of your existing core banking systems and regulatory requirements. Our team maps data flows, identifies integration points, and designs a compliant architecture using enterprise-grade protocols like Hyperledger Besu or permissioned EVM chains.
Secure Gateway Development
We build and deploy a secure, non-custodial middleware layer (REST APIs, WebSocket feeds) that acts as a firewall between your legacy databases and the blockchain. This ensures real-time data synchronization and transaction processing without exposing core systems.
Smart Contract & Tokenization Engine
Our engineers develop and formally verify custom smart contracts for asset tokenization (ERC-3643, ERC-20), automated settlements, and compliance logic. We implement on-chain access controls and integrate with Chainlink oracles for real-world data.
Deployment & Monitoring Suite
We manage the phased deployment with zero-downtime strategies and provide a dedicated monitoring dashboard. You gain real-time visibility into transaction volumes, network health, and compliance alerts, with 24/7 incident response.

Technical & Commercial FAQs
Answers to the most common technical and commercial questions from financial institutions evaluating blockchain integration.
Our standard engagement follows a 4-phase methodology: Discovery & Architecture (1-2 weeks), Development & Integration (4-8 weeks), Security Audit & Testing (2 weeks), and Production Deployment (1 week). For a standard core banking ledger integration, the typical end-to-end timeline is 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
