# BIT and Kraken
> Get a Kraken sub-account from BIT, check its Unified Wallet, then create its four API keys and enter them in Blockhouse.
> [!NOTE]
>
> Kraken's Spot and Futures APIs use separate keys, so the Kraken tab in Blockhouse asks for four: a read-only and a trading key for each. Use the Kraken Pro website for these steps.
**1. Apply for your Kraken sub-account**
In the BIT Prime Brokerage portal, open **Accounts** → **Open Account**. On the **CEFI** tab, choose **Application** next to Kraken, then set:
* **Account's Type:** where it's offered, the type the strategy needs, such as **Portfolio Margin** on Binance
* **Custody:** **Kraken with no external Custody**
* **Account's Api:** **Create API by yourself**
Choose **Confirm** and complete the verification. BIT usually approves the sub-account within a day. Then, in **Accounts** → **My Accounts**, choose **Login Info** on its row for the sub-account's login, and log in to it for the steps below.
> [!NOTE]
>
> The other custody options, such as Ceffu, Copper or Oasis, are only needed if you're taking out a loan through BIT. If you are, ask BIT which one to choose, and make sure every sub-account you apply for is in the same [risk control unit (RCU)](https://docs.blockhouse.app/reference/glossary.md#risk-control-unit-rcu): confirm both with your BIT contact.
**2. Check the Unified Wallet and derivatives**
In the sub-account on Kraken Pro, the portfolio overview should show **Main · Unified** and a **Derivatives** card. If either is missing, ask BIT to enable them before you create the keys.
**3. Create the Spot read-only key**
In Blockhouse, on the **Kraken** tab of the Credentials step, choose **Copy** → **Comma** on the **Read-only API IPs**.
On Kraken Pro, open the profile icon → **Settings** → **Connections & API**, then under **Spot trading API** choose **Create API key**. Enter a name, such as `Blockhouse read-only`, and tick only:
* **Funds permissions:** **Query**
* **Orders and trades:** **Query open orders & trades** and **Query closed orders & trades**
* **Data:** **Query ledger entries** and **Export data**
Leave **WebSocket interface** off. Turn **IP address restriction** on and paste the IPs, then choose **Generate key** and enter your 2FA code. Paste Kraken's **API Key** and **Private Key** into **Spot Read-only API Key** and **Spot Read-only Private Key** in Blockhouse straight away.
**4. Create the Spot trading key**
In Blockhouse, choose **Copy** → **Comma** on the **Trading API IPs**, then create a second Spot key the same way, named such as `Blockhouse trading`, with those IPs. Tick the same permissions, plus **Create & modify orders** and **Cancel & close orders**. Leave **Deposit**, **Withdraw** and **Earn** off.
Paste its **API Key** and **Private Key** into **Spot Trading API Key** and **Spot Trading Private Key**.
**5. Create the Futures read-only key**
On the same page, under **Futures trading API**, choose **Create API key** and set:
* **General API:** **Read only**
* **Withdrawal API:** **No access**
* **IP address restriction:** on, with the **Read-only API IPs**
Choose **Generate key** and enter your 2FA code. Paste Kraken's **Public Key** and **Private Key** into **Futures Read-only API Key** and **Futures Read-only Private Key**.
**6. Create the Futures trading key**
Create a second Futures key with:
* **General API:** **Full access**
* **Withdrawal API:** **Full access**, so the strategy can move margin between this account's Futures and Spot wallets. On a Futures key, it can't send funds anywhere else.
* **IP address restriction:** on, with the **Trading API IPs**
Paste its **Public Key** and **Private Key** into **Futures Trading API Key** and **Futures Trading Private Key**, then tick **IPs are whitelisted for read-only API** and **IPs are whitelisted for trading API**: the boxes cover both the Futures and Spot keys.
| Kraken key | Kraken shows | Blockhouse fields |
| - | - | - |
| Spot read-only | **API Key**, **Private Key** | **Spot Read-only API Key**, **Spot Read-only Private Key** |
| Spot trading | **API Key**, **Private Key** | **Spot Trading API Key**, **Spot Trading Private Key** |
| Futures read-only | **Public Key**, **Private Key** | **Futures Read-only API Key**, **Futures Read-only Private Key** |
| Futures trading | **Public Key**, **Private Key** | **Futures Trading API Key**, **Futures Trading Private Key** |
**7. Finish in Blockhouse**
In the BIT Prime Brokerage portal, open **Accounts** → **My Accounts**. In the **Sub-account List**, copy the **Account Number** for Kraken, for example `1234567_kraken_000001`. In Blockhouse, on the **Kraken** tab, enter it in **BIT account number for Kraken**.
Check that every key field on the tab is filled in and both IP boxes are ticked. Set up any other exchange from the [BIT guide](https://docs.blockhouse.app/open-an-account/connect-your-exchanges/prime-brokers/bit), then [submit the Credentials step](https://docs.blockhouse.app/open-an-account/connect-your-exchanges).
