Open infrastructure for wallet-signed Polymarket copy trading on Polygon.
A wallet-signed, sub-second mirroring engine. The operator never holds keys, never pools funds, never sees your USDC except as on-chain transfers between addresses you control.

Six modules. Each does one thing. Each is replaceable in a future release. Nothing in this stack reaches into your wallet — every signature is yours.
LISTENER
Subscribes to CLOB.OrderFilled events on Polygon. Decodes every tracked-wallet trade with WebSocket fallbacks across redundant RPC providers.
SIGNER
EIP-4361 sign-in only. Mirrored orders are dispatched to the user wallet for local signature. The operator never holds a key.
RISK GATE
Per-trade cap, daily loss, drawdown pause, liquidity floor, correlation cap, time window — six gates evaluated before submission.
SIZER
Proportional sizing keyed to allocation budget and source-trade size. Bankroll- and slippage-aware.
EXECUTOR
Three-phase order placement with progressive price adjustments. Maximizes fill probability without walking thin books.
MONITOR
Live latency, fill rate, P&L attribution, per-stream correlation. Telemetry only — the bot operates correctly without it.
From source fill to mirrored order, in one diagram.
The whole flow is six hops. The longest hop is the network round-trip to the user's wallet for signature. Everything else is microseconds.
Connect → activate in roughly two minutes.
No coding required at the user layer. The full surface area you actually touch is four steps. Identical at $200 and $200K of starting allocation.
Connect
wallet.connect("metamask") · reads address only · no transfer authority
Approve
usdc.approve(POLYMARKET_CLOB) · revocable allowance · funds remain in wallet
Configure
select wallets · set caps + liquidity floor · pick categories
Activate
listener spawns · risk gates arm · sign requests routed to wallet

Live ranking of source wallets. Realized profit, win-rate, sample size, category specialization — calibrated against resolved markets on the Polymarket protocol. The deeper framework lives in the academic literature on smart-contract execution.

Custodial vs. non-custodial: what actually changes.
Custodial "social trading" platforms collapse into a single point of failure: the operator's deposit address. The non-custodial path keeps every guarantee that prediction markets were architected to provide.
| property | non-custodial | custodial | manual |
|---|---|---|---|
| User holds keys | + yes | - no | + yes |
| Funds in shared address | + never | - required | + never |
| Sub-second mirroring | + <1s | ~ variable | - manual |
| Pre-submission risk gates | + enforced | ~ optional | - user only |
| Liquidity-floor filtering | + built-in | - rare | ~ eyeball |
| On-chain audit trail | + native | ~ internal | + native |
| Time-to-live | + ~2 min | ~ KYC delay | ~ hours |
Three tiers. All non-custodial. All paid in USDC.
Settlement runs on Polygon, Ethereum, Arbitrum, or BNB Chain. Cancel any time — your wallet remains untouched.

From traders running it in production.
"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."
