Step 1 — Find a Trader Worth Copying

1

Open the Polymarket leaderboard

Go to polymarket.com/leaderboard or browse Shadower's leaderboard which shows win rate, ROI, and P&L side by side for 300+ wallets, or jump straight to our hand-picked best traders.

Sort by ROI or P&L over the last 30 days. Ignore the all-time view — you want active traders who are profitable right now.

What to look for: Win rate above 60%, at least 50 total trades, positive ROI over the last month.
2

Copy the wallet address

Click on a trader's profile. You will see their full wallet address (starts with 0x…). Copy it — you will need it in step 4.

Avoid: 100% win rate on fewer than 20 trades. This usually means the trader only bets on near-certain outcomes (99¢ contracts) — technically profitable but negligible returns to copy.

Step 2 — Sign Up for Shadower

3

Create your account — nothing to install

Go to shadower.trade/app and sign up with email, Google, or Discord. Shadower runs in your browser and in the cloud — there is no app to download, and no Alchemy or RPC key to configure. We handle all the blockchain infrastructure on the server side.

The 3-day free trial activates automatically. No credit card required.

Runs 24/7: because the bot lives in the cloud, it keeps copying trades even when your computer is off or your browser is closed.

Step 3 — Connect Your Wallet and Set Risk Limits

4

Enter your Polymarket CLOB key

In the dashboard, paste the CLOB key of the wallet you want to trade from — not the wallet you are copying.

Security: Your key is encrypted with AES-256-GCM using AWS Key Management Service and stored on our servers — never in plain text. Decryption is bound to your account, and the bot only places trades, never withdrawals.
Recommended: use a dedicated wallet funded only with the USDC you intend to trade — never your main wallet. This is your primary protection.

Paste the trader's wallet address

Add the wallet address you copied in Step 1. You can add multiple wallets to copy several traders at once.

6

Set your risk limits

This is the most important configuration step. Always set:

  • Max single bet — the maximum USDC amount per copied trade (e.g. $50)
  • Daily loss cap — Shadower stops trading for the day if this is hit (e.g. $200)
  • Min bet filter — ignore small positions below a threshold
Do not skip this. Without limits, Shadower will copy every trade including large unusual positions. Always set a max bet before starting.

Step 4 — Start Copying

7

Press Start and monitor the live feed

Once started, Shadower listens to every new Polygon block via WebSocket. When a tracked wallet places a bet, Shadower detects it in ~1.8 seconds and places a matching order on your account automatically.

The live activity feed shows every detected and copied trade in real time. You can pause or stop at any point.

First copy trade: It may take minutes or hours for the tracked wallet to make a move. This is normal — you are waiting for their next real trade, not a historical replay.

Common Mistakes to Avoid

Frequently Asked Questions

How much USDC do I need to start?
There is no minimum. Most users start with $100–$500 to test. Shadower's proportional sizing automatically scales copied bets to your balance.
What happens to open positions when I stop the bot?
Open positions remain open on Polymarket. Stopping the bot does not close them. You can manage them manually from polymarket.com or use the auto-sell feature to close at a target price.
Do I need to install anything or keep my computer on?
No. Shadower is a web app that runs 24/7 in the cloud. Once you start the bot it keeps copying trades even when your computer is off or your browser is closed.
Is my private key safe?
Your key is encrypted with AES-256-GCM using AWS Key Management Service and never stored in plain text. Decryption is bound to your account and the bot only places trades, never withdrawals. We recommend using a dedicated wallet funded only with your trading amount.
What if the tracked trader makes no trades for days?
Shadower simply waits. There is nothing to copy if the wallet is inactive. Consider adding more active wallets to your tracking list.
