Shadower isn't for everyone
Your algorithmic edge on Polymarket
24/7 Autonomy
The best trades often happen when you're offline. Shadower tracks your selected wallets and executes orders around the clock. Focus on strategy, not on refreshing the page.
First-mover advantage
In copy trading, slippage eats your profit. Shadower reacts to a whale's move in ~1.8 seconds — getting you better odds before the market adjusts.
Scale without chaos
You don't have to pick one favorite. Add multiple top wallets to a single list and the bot turns their activity into one clean, consistent trade flow. No more tab-switching to catch everything.
Risk control without spreadsheets
Set a maximum bet size and an hourly spending limit — the bot will never exceed them. No emotional oversizing at 3am.
Full-cycle automation
What happens every single time a tracked trader makes a move.
Signal
A top trader opens a position on Polymarket (e.g. a YES outcome).
Polygon network
The smart contract confirms the transaction and writes it to the blockchain.
Detection · 1.8s
Shadower scans blocks via WebSocket connection in real time, finds the trade and instantly analyzes it.
Execution
Your bot opens an equivalent position. Size is proportional to your balance, within your set limits. Trade done.
Watch trades happen in real time
Every trade from every wallet you track — streamed from the blockchain and copied instantly.

Everything you need, nothing you don't
Real-time WebSocket
Connects directly to the Polygon blockchain and detects each tracked trade in ~1.8s on every new block. Nothing to set up on your side.
Multi-wallet tracking
Track multiple traders simultaneously. Toggle each wallet on/off without restarting the bot.
Proportional sizing
Automatically scales copied bets to your bankroll. Trader bets $1000, you bet your configured %.
Full copy controls
Bet ratio, min/max bet, price range, hourly limit, order type, auto-sell. Copy on your terms — not blindly.
Auto-sell
Automatically sells your position when price hits 99¢. Adjust the target or disable it entirely — you stay in control.
8 languages
English, Russian, Chinese, Spanish, Portuguese, Turkish, Korean, Ukrainian — full UI translation.
The app, no filters
Your key is encrypted. We only trade — no withdrawals.
Here's exactly what happens with your CLOB key — and what doesn't.
AES-256-GCM encrypted
Your CLOB key is encrypted before being stored. Plaintext is never written to our database.
KMS key management
The encryption master key is managed by KMS — not hardcoded, and no human has direct access to your plaintext key.
Trading operations only
Shadower only places bets on Polymarket on your behalf. Our system does not initiate fund transfers or withdrawals.
Use a dedicated wallet
Create a separate Polymarket wallet for the bot and fund it only with your trading USDC. This is the standard practice and your primary protection.
One price. Everything included.
No per-trade fees. No commission on profits. Cancel anytime.
No trade fees. No profit share.
Most Polymarket copy bots take 0.5–1% of every trade you copy — on $10,000 copied that's $50–100 gone, every month. Shadower is a flat subscription and nothing else. Your profits stay yours.

For two years I watched people I know feed money to bookmakers that are built so you can't win. Polymarket is different — it's a market, not a house. But earning there takes discipline, and nobody has discipline at one in the morning. So I automated it.
