Roblox offers a feature called a "star code" that allows players to donate to content producers by entering their specific star code during in-game purchases.

Roblox Star Codes can be entered when purchasing Robux in Roblox to give famous Roblox creators a small percentage of the purchase.

Roblox is ending the use of Star Codes in favor of an upcoming new program that will give creators better earning opportunities and incentives.
