Mirror Polymarket's whales with non-custodial Polymarket trading .
Polycopybot is a non-custodial Polymarket copy-trading app: it watches a chosen wallet on Polygon, scales each prediction-market position against your own rules, and submits the mirrored order signed by your wallet. USDC never leaves your control, and risk gates run before every fill.
The architecture decides everything.
Every choice underneath the surface — custody, latency, risk gates, audit trail — is the actual product. The polish is just the part you see first.
Non-custodial by design
Authentication is a wallet signature. Every mirrored order is signed locally on your device. The operator never holds a key, never pools funds, never has unilateral authority over your USDC.
Sub-second mirroring
An on-chain listener decodes the source trade, applies your risk filters, scales the position, and submits the mirrored order in well under a second on the same CLOB.
Risk gates first, fills second
Per-trade caps, daily-loss circuit breakers, drawdown pauses, and liquidity floors are evaluated before submission — not as post-hoc dashboard warnings.
On-chain audit trail
Every position the bot opens for you is a public Polygon transaction. No self-reported P&L, no proprietary "verified" badge — the trail is auditable end-to-end.
Multi-stream orchestration
Run several mirroring streams in parallel — each with its own allocation cap, liquidity floor, and category filter, plus a portfolio-level correlation budget.
Considered defaults
Sensible risk defaults out of the box. Newcomers do not need to pretend they have an opinion on the eighteenth dropdown to start safely.
How the non-custodial Polymarket copy bot goes live.
From "I just landed on this page" to your first mirrored fill is roughly two minutes — at $200 or $200,000 of starting allocation.
Connect
Sign in via MetaMask. The platform reads your Polygon address only — never requests transfer authority.
Approve
Approve a USDC allowance to the Polymarket CLOB contract. Funds remain in your wallet, allowance revocable any time.
Select
Browse the leaderboard. Filter by category. Set per-trader allocation cap and liquidity floor.
Activate
Listener spawns. Risk gates arm. Sign requests route to your wallet on every trigger.
How Polycopybot ranks the wallets worth mirroring.
Polymarket settles on Polygon, so every trade and resolution is a public transaction. The in-app leaderboard reads that on-chain history directly — no self-reported figures — and surfaces traders by realized profit, win-rate, and calibration over resolved markets. For the theory behind why calibration matters, see the prediction-market literature.
Read on-chain
Positions, fills, and resolutions come straight from Polymarket's CLOB on Polygon — the ranking is reconstructed from public transactions, not a dashboard you have to trust.
Rank by signal
Sort candidates by realized P&L, hit-rate, and how well their priced odds matched actual outcomes. Filter by category — politics, crypto, sports, macro, geopolitics.
Mirror on your terms
Pick a wallet, set a per-trader allocation cap and liquidity floor, and Polycopybot scales every new position of theirs into an order your own wallet signs.
Win-rate and profit reflect resolved on-chain history only. Past performance does not predict future results — every prediction market carries total-loss risk on staked capital.
"The cleanest property of a non-custodial copy bot is the one that is hardest to advertise: the operator could vanish at any time, and the user's funds would not move."
Custody decides everything; latency decides almost everything else. Once a copy bot is non-custodial and sub-second, the remaining surface area is taste — and taste is what most platforms in this category have ignored.
