Quick start

1. Install skill

Option A: Install from ClawHub (recommended)

clawhub install polyclaw
cd ~/.openclaw/skills/polyclaw
uv sync

Option B: Manual install

cp -r polyclaw ~/.openclaw/skills/
cd ~/.openclaw/skills/polyclaw
uv sync

2. Configure environment variables

Add the following to your openclaw.json under skills.entries.polyclaw.env:

"polyclaw": {
  "enabled": true,
  "env": {
    "CHAINSTACK_NODE": "https://polygon-mainnet.core.chainstack.com/YOUR_KEY",
    "POLYCLAW_PRIVATE_KEY": "0x...",
    "OPENROUTER_API_KEY": "sk-or-v1-..."
  }
}

Where to get the keys:

• Chainstack node — Sign up at Chainstack (free tier available, sign up with GitHub, X, or Google)
• OpenRouter API key — Create key at OpenRouter

Security warning: Keep only small amounts in this wallet. Withdraw regularly to a secure wallet.

Looking for standalone CLI usage? This skill is designed for OpenClaw. For standalone CLI usage without OpenClaw, see polymarket-alpha-bot.

3. First-time setup (required for trading)

Before your first trade, set Polymarket contract approvals (one-time, costs ~0.01 POL in gas):

uv run python scripts/polyclaw.py wallet approve

This submits 6 approval transactions to Polygon. You only need to do this once per wallet.

4. Run commands

# Browse markets
uv run python scripts/polyclaw.py markets trending
uv run python scripts/polyclaw.py markets search "election"

# Find hedging opportunities
uv run python scripts/polyclaw.py hedge scan --limit 10

# Check wallet and trade
uv run python scripts/polyclaw.py wallet status
uv run python scripts/polyclaw.py buy <market_id> YES 50

Example prompts

Natural language prompts you can use with OpenClaw:

1. Browse trending markets

What's trending on Polymarket?

Returns market IDs, questions, prices, and volume.

2. Get market details

Show me details for market <market_id>

Use the market ID from Polymarket URL or from the trending markets response above.

Returns full market info with link to Polymarket.

3. Check wallet status

What's my PolyClaw wallet balance?

Shows address, POL balance (for gas), and USDC.e balance.

4. Direct trading

If you have your own conviction on a market:

Buy $50 YES on market <market_id>

Executes split + CLOB flow and records position.

5. Hedge discovery flow

Find LLM-analyzed arbitrage opportunities:

Find me some hedging opportunities on Polymarket

or more specifically:

Run hedge scan limit 10

Note: This takes a few minutes. The skill fetches open markets and sends pairs to the LLM for logical implication analysis.

Review the results — you'll see coverage tiers (T1 = 95%+, T2 = 90-95%, T3 = 85-90%) and the market pairs where you can take hedged positions.

6. Check positions

Show my PolyClaw positions

Lists open positions with entry price, current price, and P&L.

7. Sell early

To exit a position before the market resolves:

Sell my YES position on market <market_id>

Sells your tokens on the CLOB order book at current market price.

Full flow example

1. "What's trending on Polymarket?" → Get market IDs
2. "Run hedge scan limit 10" → Wait for LLM analysis
3. Review hedge opportunities with coverage tiers
4. "Buy $25 YES on market abc123" → Take position on target market
5. "Buy $25 NO on market xyz789" → Take position on covering market
6. "Show my PolyClaw positions" → Verify entries and track P&L

Environment variables

| Variable | Required | Description | |----------|----------|-------------| | CHAINSTACK_NODE | Yes (trading) | Polygon RPC URL | | OPENROUTER_API_KEY | Yes (hedge) | OpenRouter API key for LLM | | POLYCLAW_PRIVATE_KEY | Yes (trading) | EVM private key (hex) | | HTTPS_PROXY | No | Only needed if CLOB orders fail (see troubleshooting) | | CLOB_MAX_RETRIES | No | Max retries for CLOB orders (default: 5) |

Trading flow

1. Set approvals (one-time): polyclaw wallet approve
2. Execute trade: polyclaw buy <market_id> YES 50
   • Split $50 USDC.e → 50 YES + 50 NO tokens
   • Sell 50 NO tokens via CLOB → recover ~$15 (at 30¢)
   • Result: 50 YES tokens, net cost ~$35
3. Track position: polyclaw positions

Understanding the split mechanism

Polymarket uses a Conditional Token Framework (CTF). You can't directly "buy YES tokens" — instead:

1. Split: Deposit USDC.e into the CTF contract, which mints equal amounts of YES + NO tokens
2. Sell unwanted: Sell the side you don't want via the CLOB order book
3. Result: You hold your desired position, having recovered partial cost from selling the other side

Example (buying YES at $0.65):

Split:  $2 USDC.e → 2 YES + 2 NO tokens
Sell:   2 NO tokens @ $0.35 → recover ~$0.70
Net:    Paid ~$1.30 for 2 YES tokens (effective price: $0.65)

CLOB order IDs

When you execute a trade, the CLOB sell returns an order ID like:

0xc93d6214515b2436feb684854c98d314ad19111d7ab822a9c885d61588d5beaa

This is not a blockchain transaction hash — it's an off-chain Polymarket order book identifier. CLOB orders are matched off-chain and settled in batches on-chain.

What you can do with the order ID:

Query order details via the CLOB API (requires wallet authentication):

from py_clob_client.client import ClobClient

client = ClobClient("https://clob.polymarket.com", key=private_key, chain_id=137)
creds = client.create_or_derive_api_creds()
client.set_api_creds(creds)

order = client.get_order("0xc93d6214...")
# Returns: id, market, side, price, size_matched, status, created_at, etc.

API endpoint: GET https://clob.polymarket.com/data/order/<order_hash>

Response fields: id, market, asset_id, side, price, original_size, size_matched, status (MATCHED/LIVE/CANCELLED), type (FOK/GTC), created_at, maker_address, associate_trades

Note: There's no public explorer for CLOB order IDs. To view your trade history, connect your wallet at polymarket.com → Portfolio → Activity.

Hedge discovery flow

1. Scan markets: polyclaw hedge scan --query "election"
2. Review output: Table shows Tier, Coverage, Cost, Target, Cover
3. Analyze pair: polyclaw hedge analyze <id1> <id2>
4. Execute if profitable: Buy both positions manually

Coverage tiers:

• Tier 1 (HIGH): ≥95% coverage — near-arbitrage
• Tier 2 (GOOD): 90-95% — strong hedges
• Tier 3 (MODERATE): 85-90% — decent but noticeable risk
• Tier 4 (LOW): <85% — speculative (filtered by default)
