There are several marketplaces in the game to sell your NFTs: \
\
**Marketplace Laboratory:** to sell a potion. \
\
**Marketplace Nursery:** to buy eggs from the nursery.\
\
&#x20;**Marketplace Training Center:** to buy training or become a coach. \
\
**Marketplace Players:** to sell your ZAIs, eggs, potions, or any other NFTs.
