Setup

# Install dependencies
pip install -r requirements.txt

Configure credentials

Method 1: Via openclaw.json (Recommended)

Add to your ~/.openclaw/openclaw.json under skills.entries:

{
  "skills": {
    "entries": {
      "polymarket": {
        "env": {
          "POLYMARKET_PRIVATE_KEY": "your_wallet_private_key",
          "POLYMARKET_PROXY_ADDRESS": "0x_your_proxy_wallet_address"
        }
      }
    }
  }
}

Or use the shorthand apiKey field for the primary key:

{
  "skills": {
    "entries": {
      "polymarket": {
        "apiKey": "your_wallet_private_key",
        "env": {
          "POLYMARKET_PROXY_ADDRESS": "0x_your_proxy_wallet_address"
        }
      }
    }
  }
}

Method 2: Via config file (Legacy)

Create ~/.openclaw/credentials/polymarket.json:

{
  "private_key": "your_wallet_private_key",
  "proxy_address": "0x_your_proxy_wallet_address"
}

The skill checks env vars first, then falls back to the config file.

Credential details:

  • POLYMARKET_PRIVATE_KEY / private_key — Your wallet private key (from MetaMask or similar)
  • POLYMARKET_PROXY_ADDRESS / proxy_address — Your Polymarket proxy wallet address (from polymarket.com/settings)
  • API credentials (apiKey, secret, passphrase) are auto-generated on first trade and cached locally.

Security Warning

  • Strongly recommended: Use a dedicated wallet with limited funds, NOT your main wallet.
  • The private key is only used locally for signing transactions via py-clob-client. It is never transmitted to any endpoint other than clob.polymarket.com (Polymarket's official CLOB API).
  • If using config file method: chmod 600 ~/.openclaw/credentials/polymarket.json
