We’d like to welcome One Arena @Rosentica to ST Black. One Arena is a TCG app on Solana. Rip packs, collect real graded cards, battle, and hang with other collectors in one place. Most tokenized cards sit idle in a vault. They make those cards playable so people can actually use them and win more packs. Physical TCG is already a multibillion dollar market across Pokémon, One Piece, Dragon Ball, Magic and more. A lot of those cards are now onchain, but almost none of them actually get played. That idle inventory is the gap One Arena is going after. They’ve been live on Solana for 3 months, with $2M in sales and over 10,000 games played. @tabinekokiki (CEO) worked eleven years in Japanese gaming and IP, collector for two decades. @0x_noot (CTO) has 12 years in game dev and has been a competitive TCG player even longer. They also come from the most recent @Colosseum cohort. Say hi if you rip packs, battle or work on some cool RWA stuff together.

The updated Seeker Dashboard is now live, featuring new perks from One Arena by @Rosentica. Seeker holders can open packs for real graded cards, build lineups, and compete in the Seeker Cup for a share of a $50,000 prize pool. Track rewards 👇
