# Built in Commerce Tab

Inside the wallet, a “Buy” tab opens a storefront powered by the Native Commerce Protocol. Users can:

* Purchase gift cards (Amazon, Google Play, Steam, Uber, etc.) in seconds.
* Top up mobile phone plans (over 150 countries).
* Buy eSIM data packages for international travel.

All purchases are made directly with the wallet’s balance ($UCHN token or SOL). The wallet automatically handles the payment contract interaction and displays the voucher code.

*User benefit: No need to visit a third‑party website or go through KYC. The wallet is the point of sale.*
