Online Banking Platform Modernization

Business Challenge

A commercial bank wanted to extend its online and mobile banking platform by integrating cryptocurrency wallets. Customers increasingly demanded the ability to manage digital assets alongside traditional banking services, but the bank’s existing systems were not designed to handle real-time crypto transactions, multi-currency support, and secure wallet management.

Key challenges included:

• → Enabling secure storage and management of cryptocurrency alongside traditional accounts
• → Ensuring real-time processing and updates for crypto transactions
• → Integrating crypto wallets seamlessly into web and mobile platforms
• → Maintaining compliance with financial regulations and security standards
• → Supporting high scalability to handle increasing numbers of crypto users and transactions

Solution Delivered

We designed and implemented a secure, scalable crypto banking solution integrated within the existing online and mobile platforms. The system enables users to manage cryptocurrency wallets, perform transactions, and view balances in real-time alongside their traditional banking accounts.

The solution included:

• → A microservices-based backend to decouple crypto services from core banking and ensure maintainability
• → REST APIs and WebSocket integration to deliver real-time updates for transactions and balances
• → AWS serverless infrastructure for auto-scaling and cost-efficient handling of variable transaction loads
• → Secure wallet storage, encryption, and key management mechanisms aligned with industry standards
• → CI/CD pipelines using AWS CodeCommit and CodeDeploy for reliable and automated deployments

The platform was designed for flexibility and extensibility, allowing the bank to add new cryptocurrencies, third-party integrations, and services as demand grows.
