iVOBS

A marketplace where crypto and fiat meet

iVOBS is a crypto marketplace where freelancers and businesses sell services and goods. Using on-ramp and off-ramp technology, it bridges traditional payments and crypto. A customer can pay by card or bank transfer while the merchant receives crypto, or the other way around. The main challenge was holding and moving users' funds securely across both worlds, along with handling KYC verification for every merchant. The project was showcased at Web Summit Qatar 2026.
