ScentSwap

ScentSwap is a mobile + web marketplace for buying, selling, and trading fragrance decants (2–10ml) with built-in authenticity and hygiene guardrails. Users list decants with batch/lot info, source proof (receipt/order screenshot), bottle photos, and fill-level verification. Buyers can search by notes, season, longevity, and “smells like” comparisons, then bundle multiple decants to reduce shipping. The app provides standardized listing templates, recommended pricing based on recent sales, and escrow-style payouts released after delivery confirmation. It also supports “Discovery Packs” curated by reputable sellers, plus a lightweight reputation system that rewards consistent, verifiable listings. This is a combination traditional + AI app: AI helps normalize note profiles, detect suspicious listings, and power better search, but the core value is a safer, more efficient decant market than scattered forums and DMs.
