Disconnecting deletes the encrypted key and every record synced with it from our storage. Your Polymarket account is untouched; revoke the key there too if you want it gone everywhere.
Your Polymarket, by the game.
Connect your Polymarket US account and see what each game actually paid: money in, money back, fees, net. Free, read-only, nothing here can place a trade.

Connect your account.
Polymarket US gives every account an API key. Paste it here and Sideline reads your trades, settlements and transfers with it.
- Open polymarket.us, sign in, go to Settings → API keys (or Developer).
- Create a key. Copy the Key ID and the Secret key. The secret is shown once.
- Paste both below.
What Sideline does with it. Encrypts it before storing it. Calls only the read endpoints (balances, positions, activity). Never places, changes or cancels an order. You can delete it, and everything synced with it, at any time with one tap.
What Polymarket does not offer yet. Read-only keys. A key you paste here could trade if someone stole it from us, which is why it is encrypted at rest with a key that is not in the database. We have asked Polymarket for read-only access.
