The Manifesto

Across from you,
there is always someone.

On Ktkarena, nobody sets the rules in their own favour. When a challenge is taken up, it's by someone — never by us. Both stakes are locked. The result decides, the winner takes the pot. We take 1.5 to 5% of the pot for the matchup. That's it.

Ktkarena never plays against you.

Two players, two locked stakes. The winner takes the pot, minus our commission.

Four products.
One single arena.

KTK

The Challenge

You pick your outcome. The system finds an opponent.

Live matching in two phases: placement cascade + continuous search. Fair pool phase at the end of the event. 5 stake tiers from 1,000 to 20 million KTK.

We confirm at 9pm?

The Progression

XP, levels, missions. Like a game, but better.

Free Prediction Mode to practice without staking. Achievements, badges, leaderboards, streaks. Levels 1 to 50.

The event is just an excuse.
The real game: who you challenge.

You know that conversation that always ends with "prove it." Ktkarena is that conversation at scale. With your neighborhood friends in a private league. With your university crew from afar. With your brother who supports the other team. With a stranger on the other side of the continent who thinks the exact opposite of you.

The Wall

The Wall is public. You need not be.

That stranger who thinks the opposite of you — you no longer have to go looking. On the Wall, you are the one making the offer — the event, the outcome, the stake — and anyone can take you at your word.

STAKE LOCKED

SEAT OPEN

same stake · ×2 before commission

Locked before the opponent

Your stake goes into escrow as soon as you post. When you see a klash, the money is already there: nobody can post a challenge they could not honour.

One taker, stake for stake

No cascade, no pool, nothing to negotiate. A single player accepts, for the same stake as yours: the pot is worth two stakes, commission deducted. The klash is on.

Anonymous if you want

Your challenge is on display, your name is not — no handle, no photo, no level. Anonymity hides an identity, not a commitment: your stake is locked, anonymous or not.

You can start a challenge on anything that can be verified.
