[ About ]3Blokk creates technology that points outward, not inward. We design apps that inspire people to move, explore, and engage with the real world - its communities, cities, and shared human experiences. Using blockchain and next-generation technologies, our mission is simple: to make technology an addition to life, not its focus.
[ PROJECTS ]Introducing fill, an app that reimagines how you pay for fuel by bringing instant Bitcoin Lightning payments to the gas pump.
[ OVERVIEW ]The app shows nearby stations, lets you choose your fuel and amount, and pay in seconds with low fees and no credit card holds. You fuel up as normal, and any unused amount is automatically refunded, along with built-in savings that make every stop cheaper. Designed for speed, privacy, and simplicity, fill bridges everyday fueling with next-generation payments, giving drivers a smarter, smoother way to pay at the pump as Lightning adoption continues to grow.
Founder
Michael McDonough
At 3blokk, I lead a team creating technology that quietly enhances everyday life. Originally from the UK and now based in Dallas, I spent over 13 years in London working with leading creative and digital organisations, shaping experiences that blend innovation with practicality. That design background guides how we build at 3blokk: intuitive, human products that challenge legacy systems and put people first. Our vision is a family of tools where technology fades into the background, serving users rather than the other way around.
