Skill: Polymarket Trading Setup
Use this skill when the user wants to: Set up automated trading on Polymarket Build a Polymarket trading bot from scratch Configure wallet, API credentials, or token approvals for Polymarket Understand how to connect to Polymarket's APIs Debug issues with an existing Polymarket bot setup The full technical reference is in GUIDE.md (same directory as this file). Read it before starting.
What You're Setting Up
Polymarket trading requires four things in order: A funded proxy wallet with USDC on Polygon Token approvals (USDC spend approved for exchange contracts) CLOB API credentials (derived from the wallet, stored in env) Connectivity verified across all four API surfaces
Step 1: Check What Already Exists
Before doing anything, check: Is there an .env file with POLYMARKET_PRIVATE_KEY and POLYMARKET_PROXY_ADDRESS? Is there a config.json with Polymarket settings? Is there an existing bot directory to work within? If credentials already exist, load and validate them rather than starting from scratch.
Step 2: Environment Setup
If starting fresh, create a .env file with: POLYMARKET_PRIVATE_KEY=0x... POLYMARKET_PUBLIC_ADDRESS=0x... # proxy wallet address POLYMARKET_PROXY_ADDRESS=0x... # same as PUBLIC_ADDRESS for type 2 POLYMARKET_SIGNATURE_TYPE=2 POLYMARKET_WEBSOCKET_URL=wss://ws-subscriptions-clob.polymarket.com POLYMARKET_DATA_API=https://data-api.polymarket.com The proxy wallet address comes from the user's Polymarket account settings page.
Step 3: Install Dependencies
pip install "py-clob-client>=0.28.0" httpx "websocket-client>=1.9.0" orjson pandas python-dotenv Or add to pyproject.toml and run uv sync.
Step 4: Token Approvals
Via UI (recommended for new users): Deposit USDC through the Polymarket web app โ approvals happen automatically. Headless (server deployment): Use the programmatic approval flow from GUIDE.md Section 4. This requires Polymarket Builder API credentials (separate from CLOB creds). The four contracts that need approval are listed in GUIDE.md Section 2.
Step 5: Derive and Persist API Credentials
from py_clob_client.client import ClobClient client = ClobClient( "https://clob.polymarket.com", key=os.getenv("POLYMARKET_PRIVATE_KEY"), chain_id=137, signature_type=int(os.getenv("POLYMARKET_SIGNATURE_TYPE", "2")), funder=os.getenv("POLYMARKET_PROXY_ADDRESS"), ) creds = client.derive_api_key() # Write credentials to .env โ do not log or print them Add to .env: POLYMARKET_API_KEY=... POLYMARKET_API_SECRET=... POLYMARKET_API_PASSPHRASE=... On subsequent startups, load from env instead of re-deriving (see GUIDE.md Section 3).
Step 6: Verify Connectivity
Test each surface in order. Stop and diagnose if any step fails. import httpx, json # 1. Gamma API event = httpx.get("https://gamma-api.polymarket.com/events/slug/bitcoin-price-on-february-11").json() print(f"Gamma OK: {event.get('title')}") # 2. CLOB REST - order book book = httpx.get("https://clob.polymarket.com/book", params={"token_id": "<any_token_id>"}).json() print(f"CLOB OK: {len(book.get('bids', []))} bids, {len(book.get('asks', []))} asks") # 3. Data API - positions positions = httpx.get( "https://data-api.polymarket.com/positions", params={"user": os.getenv("POLYMARKET_PROXY_ADDRESS")} ).json() print(f"Data API OK: {len(positions)} open positions")
Step 7: Place a Test Order
Place a 2-share order at a far-from-market price (very low probability on a real market) to verify the full signing and posting flow without risk of a fill: from py_clob_client.clob_types import OrderArgs, OrderType from py_clob_client.order_builder.constants import BUY # Use a real token ID from Step 6, price far from market order = OrderArgs(price=0.02, side=BUY, size=2, token_id="<token_id>") signed = client.create_order(order) resp = client.post_order(signed, OrderType.FAK) print(resp) # Should show success: true
Key Facts to Remember
Chain: Polygon mainnet (ID: 137) Currency: USDC (0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359) Signature type 2 is standard for programmatic trading Proxy address โ signing key address โ positions live on proxy, orders signed by EOA clobTokenIds[0] = YES, clobTokenIds[1] = NO โ never mix these up Minimum order value: $1.00 โ size * price >= 1.0 Order size must be integer โ always int() Update positions only on MINED, not MATCHED โ MATCHED can fail
Common First-Time Failures
SymptomLikely Causeinsufficient balanceWrong address used (EOA instead of proxy), or USDC not depositedOrder silently rejectedPrice has too many decimal places โ round to 2dp (or 3dp if price < 0.04 or > 0.96)Order value errorsize * price < 1.0WebSocket never sends dataWrong subscription message format, or using array instead of objectPositions always emptyQuerying EOA address instead of proxy wallet addressStale positions after tradeUpdating on MATCHED instead of MINED
