About Yardii
The UNIOSUN student marketplace.
UNIOSUN's student marketplace
Yardii is where UNIOSUN students trade with each other. Everything you buy comes from someone on your own campus, every order is paid for inside the app, and you can see who you are dealing with before any money moves.
Secure payments
Every order is paid inside the app through Paystack. Your card details never touch Yardii, and you have a receipt for anything you buy.
Verified vendors
Every shop is run by a real student who has connected and had their payout account checked before their first sale.
Only your campus
Yardii is built for UNIOSUN, across 6 campus communities. Buy from people you could actually walk to.
Direct chat with vendors
Message any seller in the app before and after you buy, and reach our support team the same way when anything goes wrong.
Buying from another student used to mean trusting whoever answered in a group chat: no receipt, no record, no way back if it went wrong. We started Yardii to take that gamble out of campus trading. Sellers are real students who have put their name to a shop, orders are paid for inside the app, and your money never leaves your account until you have actually bought something.
The rest is straightforward. A vendor keeps 95 percent of every sale, paid out the next working day to an account they control, and we take 5 percent to keep the marketplace running. Nobody's money sits with us in between, and nothing is held back.
