The Exchange Shop in Evomon is on the Summon Ruins islands, and guides specifically mention Summon Ruins I as a place where the Exchange Merchant can be found.

Where to go

  • Summon Ruins I is the clearest confirmed location.
  • The merchant can also appear on other islands , since the shop/NPC does not stay in one fixed spot.
  • If you see a notification that the merchant has arrived, that island is where the shop is currently available.

What you need

  • You need Exchange Tokens/Tickets to buy items from the shop.
  • Those are obtained from summoned bosses or related farming methods in the game.

Quick note

If you were asking about the merchant’s exact current spawn , it moves around, so Summon Ruins I is the best island to check first, but it may not always be there.
