Economy

A standardized currency will be implemented¹⁾ , as well as NPC vendors for supplying early game equipment and items.²⁾ </sup> “Standardized currency [is] going to be something that should remain useful from early-game to late-game”³⁾

Players will be able to trade/barter with each-other through in-game interfaces/mechanics.

“Trading is totally allowed. Even though we now have a standard currency, there's still probably going to be a lot of haggling and bartering between players and we'll see a player-driven economy open up.”⁴⁾

“Donating” to merchants to increase their levels provides higher tier items to be sold & bought. at Roughly level 8 it seems they've unlocked everything.
