Polymarket Starter Kit

Do NOT use for

• Bets larger than $10 — if the user wants a larger stake, route to polymarket-plugin directly
• Categorical (multi-outcome) markets — this skill only handles binary YES/NO markets
• Automated / high-frequency trading — that is the polymarket-mm domain
• Any chain other than Polygon Mainnet (chain 137)
• Manually constructing EIP-712 messages or bypassing the plugin with raw signing — polymarket-plugin handles all signing internally
• Suggesting the user trade via the Polymarket website, use MetaMask, or export their private key as a fallback

Overview

This skill provides a guided first-trade flow on Polymarket for users who are new to prediction markets or want a safer, opinionated path to placing their first bet. It wraps polymarket-plugin with three added safety behaviors that polymarket-plugin itself does not enforce:

1. Budget protection — every buy is preceded by a balance check; refuses to proceed if USDC.e < 2× the intended bet size.
2. Fixed bet tiers — only $1, $5, and $10 are offered. Larger bets must use polymarket-plugin directly.
3. Binary markets only — filters out categorical markets during market discovery; only YES/NO binary markets are presented.
