Veteran engineer builds crypto hardware wallet with AI coding partner

Kazunori Asada, a veteran Japanese engineer, developed a new hardware wallet called Openloop in under nine months, utilizing AI extensively for coding and research. Despite AI's tendency to forget rules and give up, Asada maintained a hands-on approach, guiding the AI and verifying its code line by line. He leveraged the M5Stack development platform for prototyping and is outsourcing mass production to the same company, integrating custom hardware and firmware developed independently. AI

IMPACT Demonstrates AI's utility in specialized hardware development, potentially accelerating niche product creation.

RANK_REASON This is a product launch of a niche hardware device, not a frontier model release or significant industry-wide event.
