Milliseconds Matter

During the live window, users swap among the curated token list. Here’s the choreography:

  1. Quote Request

    • User selects “Swap SOL → MOONSHOT, 50 % of balance.”

    • Starry queries Jupiter’s quote endpoint, enforcing:

      • Slippage ≤ 1 %.

      • Route length ≤ 3 hops.

    • Quote returned in ~120 ms.

  2. Transaction Build & Sign

    • The swap is constructed client-side using the quoted route.

    • User signs with Privy wallet; tx is broadcast to RPC cluster.

  3. Settlement Monitoring

    • Starry listens for signatureSubscribe.

    • Once confirmed, holdings are recalculated in IndexedDB for immediate UI snap.

  4. Leaderboard Push

    • A WebSocket message {user_id, new_PnL} is diff-broadcast to all clients in the same event.

    • Average end-to-end: 650–900 ms, fast enough to feel live but fair to global latency.

  5. Throttling & Anti-Abuse

    • Max 5 tx/minute to avoid spam.

    • Sudden 100 % portfolio flips within 10 seconds trigger a “confirm twice” modal to prevent fat-finger errors.

Trades after the snapshot cut-off are accepted by the network but ignored for scoring — a visible grey banner warns users during the last 120 seconds.
