Leaderboard & Traders

Prediction markets have a rare property: trader performance is publicly verifiable. Every position, every fill, every resolution is on-chain. This makes reputation objectively measurable rather than self-claimed.

PrediX surfaces this signal across the leaderboard, public trader profiles, follow feeds, and copy trading.

Leaderboard

The /leaderboard page ranks active traders by five metrics. Sort and filter to find the right traders to learn from or copy.

Metric	Description	Update
Realized P&L	Profit locked in (USDC)	Realtime
Volume	Total trade volume	Realtime
Win rate	% of markets won / total resolved	Daily
Accuracy score	Inverted Brier score (higher = more accurate)	Daily
Streak	Consecutive winning streak	Realtime

Filters:

• Period: 24h / 7d / 30d / 90d / all-time
• Min trades: 5 / 10 / 50 (filters out accounts that got lucky by chance)
• Category: crypto / sports / politics / …

The Min trades filter is the most important quality gate. Without it, leaderboards reward variance over skill.

Trader Profile

Click a trader’s name → /profile/[address] page.

A profile shows hero KPIs (Volume, P&L, Win rate, Accuracy), active positions, full trade history, calibration chart, badges, and a follow button.

1. Public vs Private

By default, trader profiles are public:

• Active positions are visible (size, market, side, avg cost).
• History is visible.
• Aggregate stats are shown.

Tip

Users can opt out in Settings → Privacy:

• Hide active positions.
• Hide history.
• Hide identity (anonymous + pseudonym).

Note

Note: Even when hidden, the address is still public on-chain. The app only hides data at the UI level. Technically savvy users can still query the indexer.

2. Following Traders

Click Follow on any profile. You will receive notifications when the trader:

• Opens a new position above a size threshold you set.
• Closes a large position.
• Reaches a milestone (badge, streak).

A dedicated Following feed inside the app aggregates all your followed traders’ activity.

3. Copy Trading

Copy trading mirrors a lead trader’s positions automatically, with risk controls applied per follower.

Setup copy trading

1. Step 1: Select a Lead Trader

   Browse the platform to find the trader whose strategy you want to replicate.

2. Step 2: Configure Your Settings

   Click Copy Trading to open the configuration panel and adjust the following:

   • Size %: Define what percentage of the lead trader’s position size you want to mirror.
   • Max per Trade: Set an absolute cap (e.g., $100) to limit exposure on any single trade.
   • Categories: Filter your risk by selecting only specific categories (e.g., Crypto only).
   • Auto vs. Manual: Choose between auto-execute for instant mirroring or confirm each order for manual oversight.

3. Step 3: Secure Your Funds

   • Pre-fund USDC into a dedicated Copy Sub-account.

   Note

   Note: Keeping these funds separate from your main wallet helps strictly limit your financial risk.

4. Step 4: Activate

   Review your parameters and click Activate to begin following the trader’s moves automatically.

Copy trading risks

Risks to understand before activating:

• Lead trader may underperform later - past performance does not guarantee future results.
• Slippage gap: The lead enters at $0.50; you copy 30s later when the price is already $0.55.
• Fee accumulation: Copying many small leads = each lead = 1tx → gas fees add up (significantly reduced if the user qualifies for the sponsor program - applies to both account types; otherwise normal fees apply).

Caution

Start small ($50-100) and test for 1 week before scaling.

Trader Directory

The /traders page - a directory of active traders with filters:

• Sort by metric (same as leaderboard).
• Filter by category, activity period (active in 24h/7d).
• Search by address or pseudonym.

Each trader card shows:

• Avatar (gravatar or custom)
• Pseudonym (self-set) or truncated address
• Top metric (e.g. ~$12k 30d)
• Win rate / Accuracy badge
• Quick actions: Follow / Copy / View profile

Privacy & Data

Verified Traders

Traders with verified social identity get a verification badge — used as anti-impersonation:

• ENS / Lens / Farcaster verified.
• Twitter linked.
• Optional KYC (for institutional traders).
• Trader stats are computed from on-chain data → public by default.
• App overlay: pseudonym, avatar, follow graph (off-chain MongoDB).
• If you opt out the app does not expose your data, but on-chain data remains public.
• GDPR / CCPA: the right to be forgotten applies only to off-chain data (pseudonym, avatar). On-chain data is immutable.

Anti-sybil

To prevent leaderboard spam from bots:

• Min activity: > 5 resolved markets to appear on the leaderboard.
• Stake gate: Top 100 leaderboard requires staking >= 100 PRX.
• Behavior detection: Wash trading patterns and copy bots are flagged and filtered.
