02 The deal
Your money
doesn't move
until
the item arrives.
The fear when buying a collectible online is always the same: paying and never receiving it. KO stands in the middle and does not let go of the money until the deal is truly closed.
Selling requires verifying your identity. Nobody gets paid without proving who they are.
- 01
The buyer pays
HeldThe amount comes out of their KO balance and is held. The seller can see it, but does not have it.
- 02
The seller ships
In transitKnowing the money is there, they send the item with tracking.
- 03
The buyer confirms
ReleasedThey receive it, check it against the description and confirm. Only then is the payment released.
- 04
And if something goes wrong
ArbitrationOpen a dispute: the team reviews photos, messages and tracking, and decides.
03 Badges
Forty badges.
None can be bought.
Four paths — moving items, creating, teaching and competing — with ten levels each. You start in coffee and finish in gold, and the badge gains stars and detail along the way. The Marketplace has no ladder: everyone gets in there.

04 Community
What the community
achieves,
the community collects.
Besides your personal progress there are goals reached together: verified members, closed deals, tournaments played.
When a threshold is crossed, nobody wins alone. The reward is shared among everyone who was there, and some goals unlock official tournaments.
