Kaspa Marketplace
The Kaspa marketplace with escrow built in
Buy and sell physical goods, digital items and services priced in KAS — this is a marketplace for spending KAS, not an exchange for buying the coin. “Buy” opens a non-custodial escrow deal: the KAS locks in an on-chain covenant that can only ever pay the buyer or the seller. How it works ↓
How buying works
Browse without an account — search, categories, photos. The listing page shows the full terms before you commit: the price in KAS, the dispute window and the escrow fee. Every listing — text and photos — passes AI moderation before it reaches the shelf.
The Buy button doesn’t pay the seller — it joins you into an escrow deal with the listing’s exact terms. You fund it from your own wallet, and your browser re-computes the covenant address itself: it refuses to pay if the server’s parameters differ. From that moment nobody holds the money — the contract does.
The seller delivers, you release — they’re paid. The dispute window is your budget for delivery and inspection: it starts when the escrow is funded, and any time before it closes you can open a dispute — normal buyer protection, not an emergency (physical goods default to a 7-day window, up to 30 days for international shipping). Received it while a dispute is open? Just release. Buyer silent — auto-release protects the seller. In every path the covenant pays only the buyer or the seller.
Selling here
A listing is free and takes a minute: title, up to three photos, a price in KAS and a dispute window. Buyers reach you through the deal’s end-to-end encrypted on-chain chat, and every sale settles through the same escrow — so you don’t have to trust the buyer either. Listings stay on the shelf for 30 days and can be extended from your Desk.

Fair questions
Who holds the money during a deal?
Nobody. The buyer’s KAS sits in an on-chain Kaspa covenant that admits a fixed set of outcomes — and in every one the money goes to the buyer, the seller or the visible service fee. “Send it elsewhere” isn’t against the rules, it’s simply not expressible in the contract, so the network rejects it. Details: how Kaspa Escrow works.
What does it cost?
Browsing and listing are free. The escrow fee is paid on the outcome: 0.5% (min 1.2 KAS) on a normal release or refund, 2% (min 5 KAS) if a human arbiter has to rule. The exact fee is shown on the listing and again before you confirm. Deals start at 50 KAS.
What can be sold here?
Three categories: physical goods, digital items, and services or freelance work. Digital items are delivered electronically through the encrypted deal chat after escrow funding — never by shipping or tracking. OTC / crypto trades are created in the Escrow service, not listed here. An AI moderator screens every listing before publication; prohibited goods, content and scams are rejected.
Do I need an account?
No sign-up. Buying creates a key file in your browser (your Desk profile) — it stays on your device and we never see it. Chatting with a seller needs a one-time 0.5 KAS funding of your chat key; the chat itself is end-to-end encrypted messaging on the Kaspa BlockDAG.
What if the seller never ships?
That’s what the escrow is for. The dispute window is sized for delivery plus inspection — the timer starts when you fund the escrow, and the seller picks a preset that fits the shipping distance (up to 30 days for international parcels). Open a dispute any time before it closes: both sides state their claims, the deal chat becomes the case file, an AI mediator proposes an outcome and a human arbiter backs it. If the goods arrive while your dispute is open, just press Release. The seller never had your money — it was locked in the covenant all along.
