Connect KuCoin to TensorTrader: API key + secret + passphrase, paper first

KuCoin and TensorTrader

KuCoin is a centralized exchange with a broad altcoin list and a separate futures platform.

This guide shows exactly what KuCoin needs from you, how to create it without withdrawal permission, how to save it in TensorTrader on paper first, and what TensorTrader can do on KuCoin today. TradingView execution for KuCoin is not switched on yet, so this guide focuses on connecting and verifying the key.

Save the KuCoin key in TensorTrader

Verification is a real call to the exchange, not a format check. A key that verifies but reads a zero balance usually points at the wrong wallet (spot instead of futures) or an unfunded demo account.

1. 1Sign in and open Settings (the tab on the right edge), then the Exchange Auth tab.
2. 2Pick KuCoin from the venue list.
3. 3Leave the key marked as testnet / paper. New keys always start there; live is a separate opt-in after preflight.
4. 4Paste the API key and the API secret.
5. 5Paste the passphrase into the Passphrase field. It must be the one you chose when you created this KuCoin key; a passphrase from another key fails verification.
6. 6On a live-ready venue, testnet credentials save and verify on their own a moment after you stop typing ("Paper/testnet credentials save automatically"). Elsewhere, press Save & Verify. The status turns green and your balance appears when the key works.
7. 7If the venue offers more than one wallet or account, pick the one TensorTrader should trade from in the wallet picker.

What works on KuCoin today

KuCoin is connectable but not live-ready. You can save and verify a trade-only key now; execution switches on once the venue passes the same parity checklist as Binance and Hyperliquid (balances, margin, fills, reconcile, fill-based profit). Connecting now also helps us finish it, which is exactly what the Pioneer program rewards.

key storage + verification

Yes: the key is checked with a real call to the exchange.

TradingView alert execution

Not yet. Alerts for this venue are not executed until it has a verified paper path.

live-ready (paper-first parity checklist)

Not yet.

paper / testnet path

Venue sandbox or demo keys where the exchange provides them; otherwise the connector stays read-only.

If the KuCoin key does not verify

TensorTrader treats authentication errors as errors and stops. It never reads a dead KuCoin key as an empty account.

invalid key

Usually a live key saved as testnet, or the reverse. Match the key to the environment.

bad signature

The passphrase is wrong or belongs to a different key.

IP restricted

The key is locked to other IP addresses; clear the allow-list or add the server’s outbound IP.

zero balance

The key works but the account or wallet it trades is empty, for example funds in spot instead of futures.

permission denied

Trade permission is off; edit the key on the exchange and enable trading (never withdrawals).

Placing KuCoin orders from TradingView

Until KuCoin is executable, alerts that name it are not turned into orders. Build your TradingView setup on a live-ready venue in the meantime: the same Batch Create alerts can later be pointed at KuCoin by changing the exchange in step 1 · Exchanges.

Beta Pioneer: 90 days, plus seats to share

A verified trade-only KuCoin key makes you a Beta Pioneer: your free beta runs 90 days instead of 30, and you get an invite code with 90-day seats for other traders. The code has 5 seats while we are still finishing a venue, and 2 once it is complete.

Find the code under Settings → Community and use "Copy invite link". Each seat gives a new account the same 90-day beta.

Frequently asked questions

Does TensorTrader need withdrawal permission on KuCoin?

No. Leave withdrawals and transfers off. TensorTrader only needs to trade and read your account.

Can I test KuCoin without real money?

Use KuCoin's sandbox or demo keys if it offers them. New keys in TensorTrader always start marked as testnet / paper.
