What can you insta-trade with gold?

[Dino]

So I was following the news of poe2 development for some time, but there have been conflicting news about the trade system, so I wanted to ask for someone to maybe clarify it to me: I know that there is still a way to trade items and currency as it was in poe1, good'ol hand-to-hand-invite-tp trade with no strings attached. But with the inclusion of gold, you now can buy and sell currency instantly, paying some gold to "the house", that was confirmed. But what I am not sure about - is there the same insta-buy/sell systems for other items as well? I know game director said earlier this year that they are going to implement this system, so you can put, say, nice pair of boots, to the market so someone can buy them instantly, but now I've seen only info on currency trade being in the game. Does anybody know for sure what you can trade this way?

As i remembered, you can insta trade with gold - orbs, scarabs, fragments. Everything with no different stats. You cant buy maps, items, eth
Everything with no variety you can trade with gold. If there is variety of stats - you can not (Sorry for poor english)

you can not buy any gear via the insta trade from players. you can pay vendors in town with gold to gain (random) rolled base gear.

as far as im informed you can buy any crafting/currency item with gold+the requested item by the player via the marked system in which you pay a small fee in gold for "the house". then you can also buy fragments and div cards.

it should be the same kind of items which are already buyable in the poe1 version of it:
