KnightTrader Poly wakes every 5 minutes, looks at every crypto up/down market, and only bets the exchange minimum until the account is ahead by a lot. It also checks markets that end within those same 5 minutes. Your private key never leaves this PC.
You can lose the pUSD in the Polymarket account. A 5-minute market can finish against you before the next check. Do not deposit money you cannot lose in full. Polymarket is not available in every country.

You deposit pUSD on Polymarket. That balance is the only money this app can use. Start small. The assistant is not allowed to size up until that balance is well ahead of where it began.
The app asks for the CLOB API key, secret, passphrase, and the wallet private key. Those stay in an encrypted file on this computer. Nous Portal needs a one-time ~$5 credit top-up, paid to Nous, before it will issue an AI key. After that the app picks a free model.
Download the installer, run it, and let it configure everything for you. No terminal, no Python, no PATH edits.
Each pass uses Polymarket CLOB v2. It scans every 5-minute crypto up/down market it can find, scores the book, and either does nothing or buys the minimum. It also considers markets that expire within 5 minutes of that pass, and only if the same edge test passes.
You can stop the schedule from the app. Closing the window leaves it in the tray, the same way the BloFin app does, and the two apps do not share a data folder, a port, or a process.
The KnightTrader Poly desktop app, with the trading desk reading your Polymarket cash, portfolio value, and open positions from the keys you paste in.
Windows .exe and Mac .dmg. After payment you land on the download page and pick your system. The installer is separate from KnightTrader BloFin, so both can be installed.
Setup is four Polymarket fields — API key, secret, passphrase, private key — plus the Nous key. The desk then shows that account’s equity and positions, not a shared demo book.

Yes. The Mac download is an Apple Silicon .dmg. The Windows download is an .exe. They install beside KnightTrader BloFin, not on top of it.
You need a Polymarket account that can hold pUSD, plus the CLOB API key, secret, passphrase, and the wallet private key. If you do not have those yet, create them on Polymarket before you paste them in.
Only if your own network is blocked. Among the countries free Proton usually offers, use Mexico or Romania. Netherlands and Japan only if Polymarket’s geoblock check says you are not blocked. Do not use Poland, Singapore, or a generic Canada server. Poland and Singapore are close-only on the API, and Canada blocks Alberta, British Columbia, Ontario, and Quebec.
No — not from KnightTrader. Nous Portal requires a one-time ~$5 credit top-up (paid directly to Nous) before you can create an API key. After that, the app auto-selects free AI models. You only pay Nous again if you manually switch to a paid model or Nous changes its billing.
Yes. These are short crypto up/down contracts. A wrong 5-minute window loses the stake. Only deposit pUSD you can lose in full.
