You can usually check it in Roblox’s notifications and My Transactions page. If the Robux came from a gift or a sale, the sender may appear there; if it was a direct gift card or some donation methods, the exact person may not always be shown.

How to check

  1. Open Roblox on the app or website.
  2. Tap or click the Robux icon.
  3. Open My Transactions.
  4. Look under incoming , pending , or received Robux.

What to expect

  • If someone bought your item or game pass, the Robux may show as pending for a while before it reaches your balance.
  • If it was sent through a gifting feature, you may see a notification with the sender’s name.
  • If you only see a balance increase with no sender listed, Roblox may not give you a full “who sent it” breakdown in every case.

Safety note

Don’t trust “free Robux checker” sites or anyone asking for your password. Roblox’s own account pages are the safest place to review transactions.

TL;DR

Check Robux > My Transactions > incoming/pending first, then your notifications. If no sender is listed, Roblox may not show exactly who sent the Robux in that case.
