I have been building things since my days at FUT Owerri, where we launched the university’s first campus FM radio station. In industry, I served as a global lead ASIC design engineer, helping to develop the inertial sensors used in the early versions of the iPhone. I also invented a wafer-level chip-scale packaging technology for inertial sensors. Till today, the US Government has continued to honour royalties for using my PhD research and the patent that came out of it. I am a Nigerian and I build things!
Good People, when we engineered a native blockchain for Contisx Securities Exchange, we saw an opportunity to extend that operating system into a new category of secure communication. That vision led us to build the Contisx Phone, a cryptographically secured blockchain phone designed to deliver superior communication security for individuals, companies and governments.

More About ContiSX Phone and Services

Good People, we received nearly 50 orders overnight. I thank Nigerians for always supporting this village boy. Thank you. Let me respond to some of the questions here about the Contisx Phone.
– We have prepaid participating telecommunications companies in Nigeria. When you use the Contisx Phone for messaging through Contisx Mail, voice calls through Contisx Audio, or video calls through Contisx Video, you will not consume your mobile data because access to those services is covered within our native ecosystem. However, you will need your own mobile data to use external services such as YouTube, Facebook, etc.
– When we launch Contisx Securities Exchange, you will not need data to buy stocks, FGN bonds and other investment products within our ecosystem. We have prepaid the data costs. Our philosophy is Investment Inclusion, and we want to remove barriers that prevent citizens from participating in capital markets. We expect to extend this zero-rated access beyond the Contisx Phone to our web, Android, smartTV, Chrome Extension and iPhone platforms.
– The Contisx Phone works anywhere in the world. Outside Nigeria, however, users will need mobile data to access its services. The phone can call other types of phones, but you cannot install WhatsApp, Facebook, Instagram or similar applications because the Contisx operating system is different from Android and iOS.
The Contisx Phone also comes with these native solutions which are available:
- Decision Lab: Gathers and interprets insights to help you make better decisions and run your business more effectively.
- Contisx Sage: Captures and interprets meeting notes in Igbo, Hausa, Yoruba, English and Pidgin. We just completed the Hausa integration in our Kano Design Center where 5 brilliant native Hausa speakers executed the playbook (middle image).
- Contisx Shield: Provides live threat intelligence and security alerts for organisations (right image)
- Business Suite: Supports bookkeeping and accounting, inventory management, human resources, payroll and access to funding opportunities.
- Boardroom: Powers board governance and preserves decisions on a sealed, tamper-evident record.
We are building a new system for secure communication, commerce, governance and investment inclusion. Preorder ContiSX Phone here https://contisx.com/phone .

ContiSX Blockchain Card

Amazing young people, thank you to everyone who sent a CV to explore opportunities at Contisx. As promised, we will launch our comprehensive careers page as soon as the stock exchange begins operations. We are now at the finish line.
But you do not have to work directly for Contisx to participate in what we are building. Through our software development kits, APIs and other tools, developers and entrepreneurs will be able to build independent solutions on our infrastructure. We want you to create for the markets around you and prepare those markets for the future.
Beyond the Contisx Phone, we have the Contisx Blockchain Card and other solutions. The phone, card and the solutions provide a foundation for secure, affordable and scalable regional digital-asset infrastructure for emergent digital economy, well beyond what we have today. It integrates seamlessly with the Contisx Phone, enabling businesses and people to manage essential commercial services through a unified platform while eliminating most costs we see in the digital rails. Imagine paying for things without those expensive transaction fees. I am sure you will want your customers to save money! And ContiSX Blockchain Card will be amazing for them; we will launch it once our exchange begins.
