JianCO white paper.

Overview of the project.

JianCO combines a holder-reward token with a free prediction-market price tool.

• Token. $JIANCO launched on pump.fun on 26 September 2026 and moved to a PumpSwap pool the same day.
• Gold pair. The pool pairs $JIANCO with GLDx, the xStocks token that tracks SPDR Gold Shares (GLD), instead of SOL.
• Holder rewards. The token's creator fee is set to pump.fun Holder Rewards and is paid to holders in GLDx.
• The Oracle. A free web tool at jiancoin.win/oracle that lists questions priced differently on two prediction-market venues, after fees.

The name comes from 健 (jiàn), meaning strong. The project's branding is humorous; the mechanics below are factual.

Holder rewards.

pump.fun Holder Rewards distribute the $JIANCO creator fee to qualifying wallets in GLDx, several times an hour.

1. Source. Each buy and sell of $JIANCO on pump.fun and PumpSwap carries a creator fee.
2. Setting. At launch the creator fee was set to Holder Rewards. According to pump.fun, this setting cannot be changed back. The project's wallets receive no separate cut.
3. Eligibility. Wallets holding more than $20 of $JIANCO.
4. Allocation. Pro rata to each wallet's $JIANCO balance.
5. Payment. In GLDx, sent automatically by pump.fun several times an hour. No claim, staking or sign-up is involved.

The size of payouts depends on trading volume. No payout amount is fixed or guaranteed.

The Oracle.

The Oracle lists prediction-market questions that two venues price differently enough that buying opposite answers costs less than the $1 payout, after fees.

This example shows a 6¢ gap before fees. Venue fees are about 3¢ per $1 on a market priced near 50¢, so many gaps disappear after fees. The Oracle lists only gaps that remain after both venues' fees, at the size both order books can fill.

Each listing shows the cost, the payout, the payout date, the available size, the time of the last price check, and any case in which the two venues' rules could settle differently. The Oracle is free, does not hold funds and does not place orders. Users place any orders themselves on each venue. $JIANCO does not trade the listings or earn from them.

How the Oracle works.

The Oracle scans three venues, verifies that paired markets describe the same event, and re-prices listings every few seconds.

1. Scan. A scheduled job reads open markets on Kalshi, Polymarket and Polymarket US about every 30 minutes.
2. Match. Candidate pairs are matched by names, teams, dates and codes. An AI model proposes harder matches using prompts from the paper “Semantic Non-Fungibility” by Gebele and Matthes; a rule-based check must confirm each one.
3. Rule check. Each pair's settlement rules are compared. Cases where the venues could settle differently are listed, and pairs that cannot be checked are excluded.
4. Pricing. The Oracle reads both order books, subtracts each venue's fees and calculates the size available before the gap closes.
5. Live checks. A service on Cloudflare re-reads order books every few seconds. Prices older than 15 seconds are shown as stale.

The paper found that identical questions are often priced differently across venues and that much of the historical return came from short-dated markets during a period without fees. The Oracle applies the same comparison with current fees included.

Roadmap (no fixed dates).

Planned work for the Oracle and the token.

• Kalshi prices refreshed within 15 seconds, matching the other two venues.
• Discovery of new market pairs inside the live service, between scheduled scans.
• Live Oracle listings posted to X as they appear and close.
• Regular public records of GLDx paid to holders, with transaction links.
• A public decision on the locked liquidity before the locks end on 31 December 2026.

Limitations and risks.

$JIANCO is paired with gold, not backed by it.

• $JIANCO has its own market price, which can fall. Holding it is not ownership of gold, GLD shares or GLDx.
• xStocks sets its own eligibility rules for GLDx.
• Holder payouts vary with trading volume and can be small or zero.
• Oracle listings can close before an order is filled, and venues can settle differently in the cases each listing names.
• The locked liquidity (38.8% of the pool) becomes withdrawable on 31 December 2026.
