Carmammas" is the future of car trading, a decentralized application hosted on our private blockchain called "Roshini." Sellers can easily list their cars for sale, offering buyers two choices: direct purchase or negotiation via offers. Purchased cars land in the buyer's virtual garage, empowering them to become sellers themselves. Buyers can also create tailored ads for specific car requirements, while sellers send proposals. Buyers can select their preferred proposal, and the rest are listed on the marketplace, creating a thriving ecosystem. Every car is represented as an NFT, ensuring trust and authenticity.
