Blockchain exchange and payment software for digital assets
HashCash operates two production blockchain platforms (PayBito.com for trading, BillBitcoins.com for payments) and sells white-label exchange and processor software to third parties. The tech stack is conventional enterprise (React, Node.js, Angular, AWS, Docker, Jenkins) with no emerging blockchain infrastructure visible — suggesting the company builds financial application layers on top of standard cloud services rather than protocol-level work. Hiring is nearly frozen (0 roles posted in 30 days) while internal effort concentrates on cloud migration, platform automation, and regulatory engagement.
