The Problem

Human error is expensive

Polymarket moves fast. By the time you notice a trade, the edge is gone.

✕ Manual trading

  • ✕Hours of wallet stalking — still miss the entry
  • ✕Emotional decisions at 2am
  • ✕Spreadsheets that are already stale
  • ✕Blink and the whale already closed

✓ Shadower

  • ✓Bot watches wallets 24/7 — set up once, run forever
  • ✓Copies in <200ms on every detected trade
  • ✓Risk limits: max bet, daily loss cap, position size %
  • ✓Full history, P&L stats, per-wallet analytics
How it works

Three steps to passive edge

01

Find a top trader

Browse Polymarket leaderboards and grab a wallet address you want to follow. Or let Shadower surface wallets by win rate and volume.

02

Set your limits

Configure copy size, max single bet, daily loss cap. Shadower scales the trader's bets proportionally to your bankroll.

03

Let it run

The bot monitors the blockchain in real time via WebSocket. When the trader bets — you bet. Automatically, in under 200ms.

Live feed

Watch trades happen in real time

Every trade from every wallet you track — streamed from the blockchain and copied instantly.

Security & Privacy

Your keys never leave your machine

Shadower runs locally. We don't see your trades, your keys, or your wallet addresses.

🔑

Local private key storage

Your Polymarket private key is stored encrypted on your device only. Never transmitted to our servers.

🏠

Desktop app, not cloud

All logic runs on your Windows PC. No cloud execution, no third party holding your funds.

🔒

Your own RPC key

Use your free Alchemy account for WebSocket access. You control the API key, not us.

🚫

No withdrawal permissions

The bot only places bets — it cannot withdraw funds. Your USDC stays safe even if something goes wrong.

FAQ

Common questions

Does the app place trades on my behalf automatically?
Yes. Once configured and running, Shadower detects trades from tracked wallets in real time and places matching orders on your Polymarket account automatically — no manual action needed.
Is my Polymarket private key safe?

No. Install the app, enter your Polymarket wallet key and a free Alchemy API key, add wallet addresses to track, and press Start. The setup wizard guides you through each step.
What is Alchemy and why do I need it?
