This link is a Binance Square / Binance Pay share link —

app.binance.com/uni-qr/cart/ is Binance's format for shareable carts / QR payments

Your specific link:
ID: cart/365168020819579
Type: uc=app_square_share_link + us=copylink = shared from Binance Square via copy-link
Referral in it: r=WR9N7RI0
Language: l=en

It's an official Binance domain, and Binance's own payment-assistant docs treat app.binance.com/uni-qr/ links as payment links, but the content of the cart can't be decoded on the web — you have to open it inside the Binance app.

To see what's inside:
Open Binance app > tap the link, or go to Square > it should open the cart/post
It will show you the products / Square post that cart ID points to

I couldn't load the actual items from the web version — it just redirected to the general Square landing page.

If you got this from someone else, double-check it — there are scam reports using the same uni-qr format with fake bonus promises, so make sure you trust the sender before scanning / paying.

What do you want to do with it? Want me to help you check if the deal inside is legit, or help you create your own share link without the referral? If you can screenshot what's in the cart, I can help compare.
