How to Export Your Polymarket Key

The exact Polymarket export flow, what the key is used for, the safety rules that matter, and what to do if you think your key has been exposed.

Last updated August 22, 2026

Polycopy places orders on your Polymarket account, and placing an order means signing it. The key you export is what makes that signature possible. It is encrypted in your browser before it leaves your device, so Polycopy never sees it in readable form. See Is My Money Safe? for how that works.

1

Log into Polymarket

Go to polymarket.com and sign in with the account you want Polycopy to trade on. If you have more than one Polymarket account, make sure this is the one holding your funds.

2

Open Account settings

Open your Polymarket account settings and find Account.

3

Start the export

Click "Start Export". Polymarket verifies it is you and then reveals your private key. You can also go straight to reveal.magic.link/polymarket using the same email you log into Polymarket with.

4

Copy the key

The key starts with 0x. Copy it. Do not screenshot it, do not email it to yourself, and do not paste it into a notes app.

5

Paste it into Polycopy Settings

Go to polycopy.app/settings, click Connect Wallet, paste the key into the field, and click Connect. Polycopy detects your Polymarket address automatically.

6

Clear your clipboard

Copy something harmless afterwards, so the key is not the next thing you paste somewhere by accident.

Rules worth being rigid about

Never share it, for any reason

Not with support, not for a verification step, not with a trading group. Anyone holding this key can move your funds.

Never paste it into a site you reached from a link

Type polycopy.app into the address bar yourself and check the domain before pasting anything.

Do not store it in plain text

If you keep a copy, keep it in a password manager. A notes app, a chat to yourself, and a screenshot in your photo roll are all readable by anything that gets into your device.

Treat a seed phrase request as an attack

Polycopy has no use for a seed phrase and will never ask for one.

What to do if you think your key is exposed

Move fast and in this order. Assume the worst rather than hoping.

1. Move your funds

On Polymarket, sell what you can and withdraw the cash to a wallet the exposed key does not control. Speed matters more than getting the best fill.

2. Disconnect the wallet in Polycopy

Settings, wallet section, Disconnect. That deletes the encrypted key from Turnkey and stops Polycopy signing anything for that account.

3. Stop using that Polymarket account for funds

You cannot rotate the key on an existing wallet, so an exposed key means that account stays exposed permanently. Start using a fresh one.

4. Tell us

Email help@polycopy.com or use the Get Help form on the help centre with the affected wallet address, written from the email on your Polycopy account.
