Emerging decentralized marketplaces often face barriers to user adoption due to unfamiliar workflows, complex wallet management, and concerns around security and trust. Dema set out to address these issues by creating a secure, user-centric platform that enables individuals to buy and sell goods or services without intermediaries. The central challenge was to design an interface that demystifies decentralized transactions, instills trust, and seamlessly guides users—regardless of their technical background—through listing, browsing, and completing trades in a peer-to-peer environment.
