# polymarket

Polymarket prediction market CLI - Browse & Trade.

## Setup

```bash
# Install dependencies
pip install -r requirements.txt
```

### Configure credentials

**Method 1: Via `openclaw.json` (Recommended)**

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

```json
{
  "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:

```json
{
  "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`:

```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`
