I will only trade with people that are at least MR(Mastery Rank) 10 and above.
Platinum will be traded for a trash unveiled riven of choice.
You will need to have 500k credits for 1000 platinum, 1m credits for 2000 platinum etc.
You will need to post your riven on either warframe.market or riven.market and I will copy-paste the message in game.
If I'm online I can make the trade in 5-15 mins.
If you have any question, don't hesitate to message me.
