What a klash is
A klash is a challenge you publish on the Wall, a public space in the app. You pick an event, an outcome, an amount - and you post it. Only a two-outcome event can carry a klash: with three outcomes or more, publishing is refused and the event is played in the arena. Your klash stays visible until someone takes it.
The difference with the arena is simple: in the arena, the algorithm looks for a counterparty for you. On the Wall, you make the offer, and someone decides to take you up on it.
Your stake is locked right away
As soon as you publish, your stake is locked on your account. It is no longer available for anything else until the klash is accepted, withdrawn or expires.
That is what makes the Wall credible: when you see a klash, you know the money is already there. Nobody can publish a challenge they could not honour.
The match itself happens in a single step: one user accepts, for a stake identical to yours, at ×2 on both sides, before commission. There is no cascade and no mutualised pool on the Wall - those mechanisms belong to the arena.
Publishing without being identified
When you publish, you can choose anonymity. The masking is then total: whoever accepts your klash sees neither your handle, nor your photo, nor your level, nor your win rate. Nothing.
This is not “Private Profile” mode, which applies to your profile. Anonymity applies to that one klash, at the moment you publish it. You can have a perfectly public profile and publish an anonymous klash.
Ktkarena, however, always knows who published what: that is needed to lock your stake, credit you, and handle any dispute. Anonymity protects you from other users, not from us. More on what others can see.
A world of its own
The Wall is a self-contained challenge context. A klash is never matched with a challenge started in the arena, in a private league or in a challenge between friends, and it does not enter into the calculation of the event's multipliers.
In practice: the anti-double-challenge rule is read per context. A challenge in the arena does not stop you taking the opposite outcome in a klash. How challenge contexts are read.
Otherwise a klash is a challenge like any other: commission, cancellation, resolution and disputes follow the same rules as in the arena.
