overview
SECURE, AUDITED CODE
Smart Contract Development
Custom smart contract development with enterprise-grade security and gas optimization.
From concept to mainnet, we deliver battle-tested contracts you can trust.
Our process includes:
- Formal Specification & Architecture: Design using industry standards like
ERC-20,ERC-721, and custom logic. - Secure Development: Write in
Solidity 0.8+orVyperusingOpenZeppelinlibraries and established patterns. - Rigorous Testing & Auditing: Comprehensive unit/integration tests, plus review by internal and third-party auditors.
- Gas Optimization: Fine-tune contract logic to reduce deployment and transaction fees by up to 40%.
Deliverables you receive:
- Production-ready, fully documented source code.
- Audit reports and a public verification package for transparency.
- Deployment scripts and post-launch monitoring setup.
- Typical MVP delivery in 3-4 weeks.

A Technical & Operational Comparison
Legacy SWIFT vs. Chainscore Modernized Workflow
Directly compare the technical debt and operational overhead of legacy SWIFT integration against a modern, API-driven blockchain solution.
| Integration Factor | Legacy SWIFT | Chainscore Modernized Workflow |
|---|---|---|
Integration Timeline | 6-12 months | 4-8 weeks |
Message Format | MT/MX (ISO 15022/20022) | REST API / Webhooks |
Settlement Finality | 1-5 business days | < 2 seconds |
Operational Cost (Annual) | $200K+ in infrastructure & support | From $50K (predictable API pricing) |
Developer Experience | Proprietary protocols, steep learning curve | Modern SDKs, comprehensive documentation |
Transaction Transparency | Opaque, bank-mediated status | Real-time, on-chain tracking |
Security Model | Centralized, perimeter-based | Decentralized, cryptographically verifiable |
Uptime & Reliability | Subject to bank/corridor hours | 24/7, 99.9% SLA |
Compliance Overhead | Manual screening, high friction | Programmable rules, embedded KYC/AML |
Scalability | Limited by correspondent banking network | Horizontally scalable with blockchain layer-2s |

MINIMIZE RISK, MAXIMIZE VALUE
Our Phased Implementation Methodology
We de-risk your SWIFT modernization with a structured, outcome-driven approach. Each phase delivers tangible value and clear milestones, ensuring alignment with your business objectives and technical requirements.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing SWIFT flows and define the target state architecture. This includes mapping message types (MT/MX), identifying integration points, and designing the smart contract logic for payment routing and compliance.

Frequently Asked Questions on SWIFT Modernization
Common technical and commercial questions from CTOs and engineering leads modernizing SWIFT-based payment systems with blockchain.
Standard deployments take 4-8 weeks from kickoff to production. This includes a 2-week discovery/design phase, 3-5 weeks of development and integration, and a final week for testing and deployment. Complex multi-bank or multi-currency projects may extend to 12 weeks. We provide a detailed Gantt chart during the proposal phase.
