Crowns can be earned as rewards while playing through PvP, PvE, and by staking your NFT in the Lending Program. Crowns are the hard currency and represent $CRT within the game (1 $CRT = 100 Crowns)
Shards represent the soft currency within Cantina Royale. They can be earned by playing with any type of character and is the main currency of the in-game economy. They can also be topped up by converting Crowns or via in-app purchases on mobile.
