Mert Sniper

Near-expiry conviction trading on Polymarket. Snipe markets about to resolve when the odds are heavily skewed.

Strategy by @mert — filter by topic, cap your bets, wait until near expiry, and only trade strong splits.

This is a template. The default logic (expiry + split filter) gets you started — remix it with your own filters, timing rules, or market selection criteria. The skill handles all the plumbing (market discovery, trade execution, safeguards). Your agent provides the alpha.

When to Use This Skill

Polymarket only. All trades execute on Polymarket with real USDC. Use --live for real trades, dry-run is the default.

Use this skill when the user wants to:

• Trade markets that are about to resolve (last-minute conviction bets)
• Filter by topic (e.g. only SOL/crypto markets)
• Cap bet size (e.g. never more than $10)
• Only trade when odds are strongly skewed (e.g. 60/40 or better)
• Run an automated expiry-sniping strategy

Setup Flow

1. Ask for Simmer API key

   • Get it from simmer.markets/dashboard -> SDK tab
   • Store in environment as SIMMER_API_KEY

2. Ask for wallet private key (required for live trading)

   • This is the private key for their Polymarket wallet (the wallet that holds USDC)
   • Store in environment as WALLET_PRIVATE_KEY
   • The SDK uses this to sign orders client-side automatically — no manual signing needed

3. Ask about settings (or confirm defaults)

   • Market filter: Which markets to scan (default: all)
   • Max bet: Maximum per trade (default $10)
   • Expiry window: How close to resolution (default 2 minutes)
   • Min split: Minimum odds skew (default 60/40)

4. Save settings to config.json or environment variables
