Footage NFTs, a.k.a. Skybox packs are virtual card packs containing K League players showing good form and potential in real life. Skybox packs consist of 4 rarity levels (highest to lowest): platinum, gold, silver, bronze. Ethe-cards, are the rarest form of NFTs which are distributed randomly and allow the holder to receive $30,000 worth of ETH via airdrop.
For every real-life performance from K League players, a few hundred-thousand dollars worth of Sportium (SPRT) coins will be airdropped to users accordingly. Goals, assists, fouls, saves; basically every player stat recorded throughout games are taken into account when associating with Sportium NFTs.
