Brokers · keep the account you have

Four brokers. One terminal.

QuantumCat isn’t a broker and never holds your money. It connects to the account you already have through your broker’s official API — and models each broker the way it actually behaves, so a control a broker can’t support is disabled with the reason instead of silently ignored.

Live Zerodha

Kite Connect — browser sign-in with automated daily login, native iceberg, and your whole Kite book.

For Zerodha Live Dhan

DhanHQ — access-token sign-in, one-click IP registration, and 20-level market depth.

For Dhan Live Angel One

SmartAPI — client code, MPIN and TOTP. No browser redirect, no daily token to paste.

For Angel One Beta Groww

Trade API — NSE and BSE cash and F&O in QuantumCat, polled prices and daily approval for the key-and-secret flow.

For Groww

Upstox and Fyers are next. Brokers’ names are trademarks of their owners; QuantumCat is not affiliated with or endorsed by any of them.

Where the order fills — through the member you already trust.

Your broker executes; the route is explicit. Requests connect directly by default, or through an optional IP relay. Account access, enabled cloud features and JARVIS use separate external connections.

Connect in minutes. Trade at 9:15.
