A Wonder Trade was a type of trade in the Generation VI and Generation VII core series titles. It could be accessed from the Player Search System, and it involves both the player and a random person in real life trading a Pokémon with one another. Likewise, the Pokémon selected during a Wonder Trade is chosen by the game at random. The mechanic was reliant on Nintendo Network for Nintendo 3DS systems, so when the service discontinued on April 8, 2024, Wonder Trades have been made no longer possible. After the Wonder Trade, both players have their information stored in their "Acquaintances" list on their Player Search System database.
In the Generation VIII games, Wonder Trade was succeeded by Surprise Trade.
