A whale-mirroring terminal for Polymarket copy trading bot on Polygon.
Sub-second on-chain detection. Pre-submission risk gates. Wallet-signed orders, every time. Built for traders who want the latency of a market maker and the custody profile of a hardware wallet.
The stack underneath the the Polymarket copy trading bot.
Built on rails most prediction-market traders already trust. Wallet-signed orders, on-chain detection, pre-submission risk gates — the architecture you would build if you cared about latency more than dashboards.
LISTENER
Subscribes to Polymarket CLOB events on Polygon. Sub-second decode of every tracked-wallet trade, with WebSocket fallbacks across redundant RPC providers.
RISK GATE
Per-trade hard cap, daily-loss circuit breaker, drawdown pause, liquidity floor, correlation cap — all evaluated before submission, not after.
SIGNER
EIP-4361 wallet signatures only. Every mirrored order is signed locally in your browser. The operator never holds a key.
SIZER
Proportional position sizing based on your allocation budget and the source trade. Bankroll-aware, slippage-aware.
EXECUTOR
Three-phase order placement with progressive price adjustments. Maximizes fill probability without walking the book.
MONITOR
Live latency, fill rate, P&L attribution, and per-stream correlation. The dashboard tells you what changed; the bot does not need it to function.
From wallet connect to first mirrored fill in roughly two minutes.
The flow is identical whether your starting allocation is $200 or $200,000. Each step is reversible; nothing is custodial.

Live on-chain ranking. Realized profit, win rate, sample size, and category specialization — calibrated against resolved markets, not self-reported claims. The full discipline behind picking wallets is laid out in the academic prediction-market literature.

"Set risk parameters once and the bot mirrors top performers in real time. Non-custodial setup is the part I keep coming back to — peace of mind I never had on the centralized side."
"Stop-losses and per-trade caps are exactly what I needed for prediction markets where liquidity is not equity-grade. The Professional plan has been a great fit for my book."
"I never had to deposit anywhere. Authentication is a wallet signature; orders are signed locally; the operator could disappear and my funds wouldn't budge. That's the bar."
Reader Q&A.
Answers to the questions that actually matter to traders. For deeper context the Polymarket protocol docs are the authoritative source.
What is whale mirroring on Polymarket?
The practice of automatically replicating the on-chain trades of a high-volume wallet on Polymarket. An event listener decodes the source transaction and submits a proportionally sized mirrored order signed by your own wallet on Polygon.
How is execution latency measured?
Detection-to-submission is measured from the moment the source transaction lands in a Polygon block to the moment the mirrored order is broadcast to the Polymarket CLOB. The platform delivers consistent sub-second latency.
Is the platform really non-custodial?
Yes. Authentication uses EIP-4361 wallet signatures and every mirrored order is signed locally by the user's wallet. The operator never has authority to move USDC.
What does it cost?
Three monthly plans: Starter $99, Professional $299, Enterprise $499. Billed in USDC on Polygon, Ethereum, Arbitrum, or BNB Chain. Cancel any time.
Can I run multiple mirrored streams?
Yes. Each stream has its own per-trader allocation cap, liquidity floor, and category filter. A portfolio-level correlation budget prevents over-exposure to a single underlying event.
Which wallets are supported?
MetaMask today; WalletConnect and Coinbase Wallet on the roadmap. EIP-4361 sign-in only — never custodial.
Does Polymarket have a built-in copy trading feature?
No. The category is supplied entirely by third-party non-custodial tools that read on-chain trades and submit mirrored orders signed by the user's own wallet.
What are the practical risks?
Past trader performance does not predict future results. Prediction markets carry liquidity risk, resolution-dispute risk, and smart-contract risk. Use per-trade caps and daily-loss circuit breakers as a baseline.
