CopyTrail

Security and custody

Your funds and your key, kept under your control

Exactly what we hold, how it's protected, and the limits that can't be crossed — in plain language.

We never custody your funds

Your USDC stays in your own Polymarket wallet. We only place copy orders at your ratio — we can't withdraw, transfer, or move funds out. If we vanished tomorrow, your wallet would be untouched.

What your key can and can't do

Can
  • Place copy orders sized to your ratio
  • Buy and sell the same markets your trader does
  • Stop the moment you pause or hit a limit
Cannot
  • Withdraw, transfer, or move your funds out
  • Send your USDC to any other wallet
  • Trade beyond your daily and monthly caps

How your key is protected

  • Encrypted with AES-256-GCM the instant it arrives — decrypted only inside the trading engine.
  • The master key is held in a managed key vault, off our application servers.
  • The encrypted key can't be read back by any login, dashboard, or API — only the engine decrypts it.
  • We verify your key matches your wallet before saving, and email you on every change.

Limits that bound your downside

  • Daily and monthly USDC caps stop spending once they're reached.
  • A minimum-trade filter skips copies below the size you set.
  • Slippage and wallet-balance checks skip unsafe fills instead of chasing them.

One pause stops everything

A single toggle halts every new copy instantly — open positions stay put. Live mode stays off until you turn it on; a paid plan alone never arms real trading.

Remove your key anytime

You can delete your encrypted key from our systems whenever you want. Copying pauses immediately, and you can register a key again later if you come back.

Use a dedicated wallet

Create a fresh wallet for copy trading and fund it with only what you can afford to lose — never register the key of your main wallet that holds long-term assets.

See it run before you trust it

Paper mode proves the whole path with $0 at risk. Browse who you'd copy first.
