Digital Asset Marketplace

The client
BLOCKSTATION Financial Technology Platform
A stock exchange technology provider enabling traditional exchanges to list and trade tokenized securities and digital assets. Blockstation needed a long-term development partner to build the core technology for their digital asset marketplace - a dedicated team with deep expertise in both blockchain and financial systems.
Project Overview
5+ Year Development Partnership We built the complete core technology for Blockstation's digital asset marketplace, including:
- High-performance trading engine (thousands of orders per second)
- Multi-blockchain integration (Bitcoin, Ethereum, Polygon)
- Complex smart contracts (Solidity) for custody and on-chain voting
- Secure digital currency custody solution
- Big Data infrastructure for trading data
- PCI-compliant architecture and KYC integration
Team Composition: 3-4 senior developers, QA engineer, DevOps specialist
Challenges
Blockstation needed to meet the demanding performance, security, and compliance standards of regulated financial exchanges while integrating cutting-edge blockchain technology:
- Performance Requirements: Achieve thousands of orders per second with mission-critical uptime for 24/7 trading
- Blockchain Complexity: Build secure custody solutions and smart contracts across multiple blockchain networks
- Regulatory Compliance: Navigate PCI compliance, KYC requirements, and custody standards
- Scale & Data: Handle massive volumes of trading data with real-time reconciliation
- Long-Term Partnership: Required a dedicated team that could commit for multi-year platform development, not rotating contractors
This wasn't a project for staff augmentation, they needed specialized expertise in both fintech and blockchain, delivered by a team that would take ownership.
