So I encountered a goblin while running campaign on my HC seasonal. It had a portal open before it saw me and before I even engaged it, and the goblin itself showed as a different icon on my map. I engaged the goblin, the portal went away and there was no portal when I killed him. I asked in general about what may have happened and I was told that the portal to the treasure realm appears after you kill a goblin and that you need a key to enter it. They also said that you have to kill Diablo 30 times or so for the key, but I can't find any information anywhere about needing a key for the treasure goblin realm. Is this true that you need a key to get into the treasure realm?

It has nothing to do with the Treasure Realm, which has a very small chance to open once you kill the gob. Hope this clarifies things.
The change to Treasure Goblin visibility by adding a portal graphic on first spawn and a mini-map icon was indeed a quality of life change meant to help you spot them more easily (and thanks to Satsui and others for providing clarification :)).
Since this change wasn’t included in the patch notes, it’s caused some confusion among players, and I wanted to add to the voices providing answers. Hope that helps (and that the new graphics make it easier to find those loot-laden gobbies)!
