Find the trade you're looking for.
Search what trainers are offering, see who wants what you have, and agree a fair Pokémon-for-Pokémon trade — then make it in your game.
Trade in the game you play: Scarlet & Violet, Legends: Z-A, Pokémon GO, Pokémon HOME, Sword & Shield, Brilliant Diamond & Shining Pearl, Legends: Arceus and Let's Go. ApexDex only lets you list Pokémon that actually exist in the game you choose.
Pick a pool — Community, Shiny, Perfect IV or Legendary — and get paired with a trainer offering the same tier in the same game. You both see what you got before anyone agrees.
