Panther offers two ways to trade. Most people use on-chain trading — it’s the default and works everywhere. API trading is a desktop-only option for people who want to connect their own exchange API keys.

​
At a glance

These are accounts you switch between, not a global toggle. Pick the active one in the account switcher. On web, only on-chain trading is available.
With on-chain trading, Panther creates two secure, self-custody wallets for you when you first sign in — one for Kalshi and one for Polymarket. You deposit USDC, and your trades are placed and settled directly from those wallets. There are no API keys to manage, and your funds stay under your control.

No keys to manage

Wallets are created automatically. Nothing to copy or paste.

Self-custody

You hold the funds and can export your keys anytime.

Works on web too

The same account works in the browser and the desktop app.

Set up on-chain trading

Sign in, add funds, and place your first on-chain trade.

​
API trading (desktop only)

API trading connects Panther to your existing Kalshi and Polymarket accounts using API keys that you create on those platforms. Your funds never leave those accounts, and your keys are stored only on your computer. This option is available in the desktop app only — the web app doesn’t support it.

Set up API trading

Connect your Kalshi and Polymarket API keys on desktop.

Which should I choose?

Use on-chain trading. It’s the default, needs no API keys, and works on both web and desktop.
You can use API trading on desktop to keep that setup — or switch to on-chain to trade from web too and let Panther handle the wallets.
