In-Game Purchases

How revenue splits work
▾

For in-game purchases, developers receive 70% and the platform takes 30%.

Entry fees for paid games are separate: 50% to the developer and 50% to the weekly prize pool.

Recommended integration flow
▾
  1. On purchase click, your game calls your backend to create a purchase intent.
  2. Your backend creates an order and returns payTo and amountKas.
  3. Front-end invokes the KasPay modal (or your UI) to send KAS.
  4. Your backend receives a payment webhook from KasPay, verifies, and marks the order paid.
  5. Your game unlocks the item after your backend confirms the order is paid.
Heads-up: We’ll share a minimal REST spec with /purchase-intent and /confirm-purchase endpoints.
Example: client calls
▾
// Create a purchase intent from your game UI
const res = await fetch('/api/purchase-intent', {
  method: 'POST', headers: {'Content-Type':'application/json'},
  body: JSON.stringify({
    userId: currentUserId,
    itemId: 'skin.mystery_box',
    priceKas: 1, // you set price
    meta: { gameId: 'your-game-id' }
  })
});
const intent = await res.json(); // { invoiceId, payTo, amountKas }

// Open KasPay modal and ask the user to send `amountKas` to `payTo`.
// After tx, poll your backend:
const poll = setInterval(async () => {
  const st = await fetch('/api/confirm-purchase?invoiceId=' + intent.invoiceId).then(r=>r.json());
  if(st.status === 'paid'){ clearInterval(poll); unlockItem(); }
}, 2500);

Entry fee integration (optional)

For paid entries, your front-end should request a start token from your backend, then launch the game.

// Start a paid match
const start = await fetch('/api/entry/start', {
  method:'POST', headers:{'Content-Type':'application/json'},
  body: JSON.stringify({ gameId: 'your-game-id', userId: currentUserId })
}).then(r=>r.json()); // { ticketId, payTo, amountKas }

// Prompt payment via KasPay, then verify:
await openKasPayModal(start.payTo, start.amountKas);

// Confirm server-side (your backend validates tx & issues session)
const session = await fetch('/api/entry/confirm', {
  method:'POST', headers:{'Content-Type':'application/json'},
  body: JSON.stringify({ ticketId: start.ticketId })
}).then(r=>r.json()); // { ok:true, sessionId }

// Launch match with sessionId
launchGame({ sessionId: session.sessionId });

We’ll supply a simple webhook contract for transaction confirmations in the MVP backend.
