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.
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.
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.
Set a maximum bet size and daily loss limit — the bot will never exceed them. No emotional oversizing at 3am.
What happens every single time a tracked trader makes a move.
A top trader opens a position on Polymarket (e.g. a YES outcome).
The smart contract confirms the transaction and writes it to the blockchain.
Shadower scans blocks via WebSocket connection in real time, finds the trade and instantly analyzes it.
Your bot opens an equivalent position. Size is proportional to your balance, within your set limits. Trade done.
Every trade from every wallet you track — streamed from the blockchain and copied instantly.
Verified wallets from Polymarket's public leaderboard. Public data, last 30 days.
Public data from polymarket.com/leaderboard · Last 30 days · Past performance ≠ future results.
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.
Track multiple traders simultaneously. Toggle each wallet on/off without restarting the bot.
Automatically scales copied bets to your bankroll. Trader bets $1000, you bet your configured %.
Max single bet, daily loss cap, min/max bet filters. Your capital, your rules.

Here's exactly what happens with your CLOB key — and what doesn't.
Your CLOB key is encrypted before being stored. Plaintext is never written to our database.
The encryption master key is managed by KMS — not hardcoded, and no human has direct access to your plaintext key.
Shadower only places bets on Polymarket on your behalf. Our system does not initiate fund transfers or withdrawals.
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.
No commission on profits. Cancel anytime.
3-day free trial. No credit card. Setup in under 5 minutes.
Trading prediction markets involves risk. Past performance of tracked wallets does not guarantee future results. Shadower is a tool, not financial advice. Only trade with funds you can afford to lose. Not affiliated with Polymarket, Inc.
