polyclaw markets trending— Top markets by 24h volumepolyclaw markets search "query"— Search markets by keywordpolyclaw market <id>— Market details with prices
polyclaw buy <market_id> YES <amount>— Buy YES positionpolyclaw buy <market_id> NO <amount>— Buy NO position- Split + CLOB execution (split USDC → YES+NO, sell unwanted side)
polyclaw positions— List open positions with live P&Lpolyclaw position <id>— Detailed position view- Positions tracked locally in
~/.openclaw/polyclaw/positions.json
polyclaw wallet status— Show address, POL/USDC.e balancespolyclaw wallet approve— Set Polymarket contract approvals (one-time)
polyclaw hedge scan— Scan trending markets for hedging opportunitiespolyclaw hedge scan --query "topic"— Scan markets matching a querypolyclaw hedge analyze <id1> <id2>— Analyze specific market pair
Uses LLM-powered contrapositive logic to find covering portfolios. Only logically necessary implications are accepted — correlations and "likely" relationships are rejected.
Coverage tiers: T1 (≥95%), T2 (90-95%), T3 (85-90%)
Option A: Install from ClawHub (recommended)
clawhub install polyclaw
cd ~/.openclaw/skills/polyclaw
uv syncOption B: Manual install
cp -r polyclaw ~/.openclaw/skills/
cd ~/.openclaw/skills/polyclaw
uv syncAdd 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.
Before your first trade, set Polymarket contract approvals (one-time, costs ~0.01 POL in gas):
uv run python scripts/polyclaw.py wallet approveThis submits 6 approval transactions to Polygon. You only need to do this once per wallet.
# 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 50Natural language prompts you can use with OpenClaw:
What's trending on Polymarket?
Returns market IDs, questions, prices, and volume.
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.
What's my PolyClaw wallet balance?
Shows address, POL balance (for gas), and USDC.e balance.
If you have your own conviction on a market:
Buy $50 YES on market <market_id>
Executes split + CLOB flow and records position.
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.
Show my PolyClaw positions
Lists open positions with entry price, current price, and P&L.
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.
- "What's trending on Polymarket?" → Get market IDs
- "Run hedge scan limit 10" → Wait for LLM analysis
- Review hedge opportunities with coverage tiers
- "Buy $25 YES on market abc123" → Take position on target market
- "Buy $25 NO on market xyz789" → Take position on covering market
- "Show my PolyClaw positions" → Verify entries and track P&L
| Variable | Required | Description |

POLYCLAW_PRIVATE_KEY |
Yes (trading) | EVM private key (hex) |
HTTPS_PROXY |
No | Only needed if CLOB orders fail (see troubleshooting) |

- Set approvals (one-time):
polyclaw wallet approve - 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
- Track position:
polyclaw positions
Polymarket uses a Conditional Token Framework (CTF). You can't directly "buy YES tokens" — instead:
- Split: Deposit USDC.e into the CTF contract, which mints equal amounts of YES + NO tokens
- Sell unwanted: Sell the side you don't want via the CLOB order book
- 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)
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.
- Scan markets:
polyclaw hedge scan --query "election" - Review output: Table shows Tier, Coverage, Cost, Target, Cover
- Analyze pair:
polyclaw hedge analyze <id1> <id2> - 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)

Set the POLYCLAW_PRIVATE_KEY environment variable:
export POLYCLAW_PRIVATE_KEY="0x..."Set the Polygon RPC URL:
export CHAINSTACK_NODE="https://polygon-mainnet.core.chainstack.com/YOUR_KEY"Required for hedge commands. Get a free key at https://openrouter.ai/settings/keys:
export OPENROUTER_API_KEY="sk-or-v1-..."Model quality matters. The default nvidia/nemotron-nano-9b-v2:free works well. If using a different model:
- Some models find spurious correlations (false positives)
- Some models return empty responses (DeepSeek R1 uses
reasoning_content) - Try
--model nvidia/nemotron-nano-9b-v2:freeexplicitly
Check balance — you need USDC.e (bridged USDC) on Polygon:
uv run python scripts/polyclaw.py wallet statusPolymarket's CLOB API uses Cloudflare protection that blocks POST requests from many IPs. The solution is a rotating residential proxy with retry logic.
Recommended setup (IPRoyal or similar):
export HTTPS_PROXY="http://user:pass@geo.iproyal.com:12321"
export CLOB_MAX_RETRIES=10The CLOB client automatically retries with new IPs until finding an unblocked one. Typically succeeds within 5-10 attempts.
Alternative options:
- Sell manually — Your split succeeded. Go to polymarket.com to sell tokens
- Use
--skip-sell— Keep both tokens:polyclaw buy <id> YES 50 --skip-sell
Run the one-time approval setup:
uv run python scripts/polyclaw.py wallet approveMIT
