Legacy approved automation only

Existing automation support.

This page is kept only for customers who were already approved for NOVA managed automation. New online buyers receive TradingView script access instead and should not send Polymarket keys, wallet keys, or exchange credentials.

Open Polymarket Account Settings Back to script access

Use a small dedicated Polymarket account.

Never paste a seed phrase, recovery phrase, exchange password, email password, or main wallet key into NOVA. Only paste the private key exported from the small Polymarket account you want NOVA to trade.

Required

Limited wallet private key from Polymarket Settings > Account > Private key > Start Export. In env files this is POLYMARKET_WALLET_PRIVATE_KEY or POLYMARKET_PRIVATE_KEY.

Automatic

NOVA creates the trading API key, secret, and passphrase later. You do not generate or paste those.

Already have CLOB keys?

Support can also use POLYMARKET_API_KEY, POLYMARKET_API_SECRET, and POLYMARKET_API_PASSPHRASE. Most users should skip these because NOVA derives them from the limited wallet key.

Wrong pages

Do not use Relayer API keys. Do not use Builders. They are not the NOVA setup key.

Step 1

Go to Account settings.

Fast path: open polymarket.com/settings?tab=account. Manual path: click your profile circle, open Settings, then click Account on the left.

Redacted Polymarket Account settings page with Account and Start Export marked. — On this page, find Sensitive > Private key, then click Start Export.

Step 2

Verify with Magic.

After Start Export, Polymarket may show Secure private key access. Log in with the same method you use for that Polymarket account. Do this only while the address bar says polymarket.com.

Redacted Magic secure private key access screen with login choices marked. — Use the account login method you normally use. Do not share the final key screen.

Step 3

Do not use Relayer or Builders.

If you are on Relayer API keys or Builders, you are in the wrong place. Go back to Settings > Account and use Private key > Start Export.

Redacted Polymarket Relayer API keys page marked do not use for NOVA. — These keys do not go into NOVA.

Step 4

Paste the key into NOVA.

In NOVA, choose I have wallet key. Paste the exported private key into Limited wallet private key. Add the public wallet/funder address only if you are sure it is from the same Polymarket account.

NOVA setup form showing the limited wallet private key field and optional public wallet address field. — NOVA creates the trading API credentials automatically. You do not paste API key, secret, or passphrase.

Stop if any of these happen.

A page asks for your seed phrase, recovery phrase, exchange password, email password, or main wallet key.
You are on Relayer API keys or Builders and trying to use those values for NOVA.
You are about to use a Polymarket account that holds funds you do not want NOVA to trade.
You are a U.S. customer trying to use Polymarket instead of the Kalshi setup path.
