Scaling India’s Crypto Backbone: Enterprise-Grade Wallet Infrastructure & KYC Automation
Architected a high-throughput exchange ecosystem supporting 15M+ users with hardened Wallet-as-a-Service (WaaS) security.
THWORKS scaled a mission-critical cryptocurrency exchange infrastructure capable of handling high-concurrency trading for over 15 million users. The project involved building a robust Wallet-as-a-Service (WaaS) layer with hot and cold storage separation and a hardened, automated KYC/AML pipeline to ensure rapid user onboarding while maintaining strict regulatory compliance and fund security.
The Challenge
The platform faced significant infrastructure strain during market volatility, leading to latency in order matching and bottlenecks in user verification. Managing private keys at scale while ensuring 100% security against external threats, combined with a manual KYC process that took days, was preventing the exchange from capturing the massive influx of new retail investors.
In the hyper-competitive fintech and crypto space of 2026, speed is the ultimate currency. The client needed to transition from a monolithic architecture to a high-availability, microservices-led environment that could process millions of transactions per second while adhering to evolving international AML/CTF standards.
Our Solution
We implemented a distributed Node.js microservices architecture optimized for event-driven processing. The core was powered by a high-performance Redis caching layer for real-time order books and a vertically partitioned Postgres database for immutable transaction logging.
To solve the security-scale paradox, we built a tiered Wallet Infrastructure. This included 'Hot Wallets' for instant liquidity, 'Warm Wallets' for operational buffers, and 'Air-gapped Cold Wallets' for long-term asset protection, all managed via a proprietary Wallet-as-a-Service (WaaS) API.
Key Technical Decisions
Automated OCR-Based KYC: Integrated an AI-driven verification engine that used computer vision to validate IDs and perform liveness checks, reducing human intervention by 80%.
Multi-Signature Authorization: Enforced m-of-n multi-sig protocols for all large-value withdrawals, ensuring no single point of failure in fund management.
CQRS Pattern: Implemented Command Query Responsibility Segregation to separate trade execution from account balance lookups, drastically reducing database contention.
Results
Before
Fragmented wallet management, manual KYC verification taking 48+ hours, and frequent downtime during high market volatility peaks.
After
Hardened, HSM-backed wallet security, automated instant KYC for 90% of users, and a platform capable of handling 10x traffic surges with zero latency.
Technology Stack
"THWORKS transformed our infrastructure from a startup MVP into a global-scale financial engine. Their approach to wallet security and automated KYC didn't just save us money—it built the trust factor necessary to lead the market."
Frequently Asked Questions
Common questions about this project and our approach.
WaaS abstracts the complexity of key management. By using a combination of MPC (Multi-Party Computation) and hardware security modules (HSMs), we ensure that funds are protected even if one layer of the infrastructure is compromised.
