Footage of Null-Field Theories, or NFTs. A virtual card pack including K League players who are performing well in the real world is called a “Skybox pack.” From platinum to bronze, there are four rarity levels in Skybox packs: platinum, gold, silver and bronze. Ethe-cards are the rarest of all NFTs. They let the owner get $30,000 worth of ETH through an airdrop.

Users will receive Sportium (SPRT) coins worth several hundred thousand dollars for each real-life performance by K League players. Every player stat recorded during a game is taken into consideration when associating with Sportium NFTs. This includes goals, assists, fouls, and saves.
