Create a Market

A strong market needs three things: a question your audience already cares about, answer labels that are mutually understandable, and a duration that matches your audience's attention window.

• Question wording is permanent on-chain once the market is created.
• Pick 2 answers for binary conviction, 3–5 for multi-perspective narratives.
• Duration range: minimum 5 minutes, maximum 90 days.
• Markets with recurring cadence should use the Series flow instead.

• topic — short category label (e.g., "BNB Chain", "Crypto AI", "Sports").
• question — the full question text (permanent on-chain).
• answers — array of 2–5 answer label strings.
• startTime — Unix timestamp; must be in the future.
• endTime — Unix timestamp; must be startTime + 5 min to startTime + 90 days.
• creatorFeeBps — your fee on every sell, 0–50 basis points (0–0.5%). Higher fees reduce trader incentives.
• virtualLiquidityKusd — total KUSD to seed all answer pools. Divided equally across answers. Must be ≤ protocol cap.

Calling createMarket triggers a multi-step atomic transaction:

• KangarooTokenFactory deploys one KangarooSentimentToken per answer.
• The V2 factory creates one KUSD/SentimentToken pair per answer.
• Virtual KUSD is minted and seeded into each pair (floor(virtualLiquidityKusd / answerCount) per pool).
• Each pool receives 9,000 answer tokens alongside the virtual KUSD (scale-converted to 18 decimals).
• The pairs are marked as protected in KangarooUSD.
• KangarooCreatorRegistry records the market under your address.
• You receive a Creator Badge (BADGE_CREATOR = 1).

• Choose topics your specific audience can judge without external expertise.
• Keep answer labels short — 1–4 words each. Avoid double-negatives or jargon.
• Set duration to match the news cycle: 24–72 hours for trending events, 7–14 days for slow narratives.
• Share the market URL immediately after creation while your audience's attention is fresh.
• Use recurring series for weekly or daily cadence topics — avoid re-creating one-off markets for the same question.
