Secure Escrow

Swappr
Sneakers · Streetwear · Trades
Buy, sell, and trade sneakers and streetwear with people you can actually verify — no seller fees, funds held in escrow until both sides are satisfied.
01 — Overview
A Marketplace Built Around the Deal, Not the Listing
Most resale happens in places that were never built for it. A buyer sends money first and hopes. A seller ships first and hopes. A trade comes down to whoever is willing to go first — and the person who does takes all the risk.
Swappr removes that gamble. Payments are held in escrow from the moment an order is placed and released only once the item is delivered and accepted. Sellers pass identity and account verification before they can list. Item-for-item trades are executed as a single structured transaction, with both sides committed at the same time.
Sellers keep what they earn — Swappr charges no seller fees on completed sales.

What Is Inside the App
02
Seller Verification
Sellers complete identity and payout verification before listing. Verification status, sales history, and dispute record are visible on every profile.
03
Trade Execution
Propose an item-for-item trade with optional cash on either side. Both parties commit before anything ships, and the trade settles as one transaction.
04
Price Alerts
Track any model and size, then get notified the moment a listing lands under your target. Set alerts on condition, size range, and price ceiling.
05
Collections
Catalogue what you own, track estimated value against live market data, and list straight from your collection when you decide to let something go.
06
Size Finder
Save your size across brands and silhouettes so the feed surfaces what actually fits — no more scrolling past listings in a size you will never wear.
