# BIT

> Your BIT transfer key, then a sub-account and keys on each exchange the strategy uses.

BIT was formerly Matrixport, and some screens still say Matrixport. Keep Blockhouse's Credentials step open in one tab while you work through this guide and each exchange's.

**1. Create the transfer key**

In Blockhouse, in **Prime Broker**, choose **BIT** and choose **Copy** → **Comma** on the **Transfer API IPs**.

In the BIT Prime Brokerage portal, open your avatar (top right) → **API Management**, which opens **API Management** on the BIT website, and choose **Create API**. Enter a label, tick **Read**, **Wallet** and **Trade** (leave **Earn** off: Blockhouse needs Wallet and Trade to move funds between your exchanges), set **Bind IP address** to **Yes** and paste the IPs into **Bind IP**. Choose **Create**, complete the verification, and copy the key and secret.

**2. Enter BIT in Blockhouse**

In **Prime Broker**, enter the key and secret, then tick **IPs are whitelisted for transfer API**.

**3. Set up each exchange**

Follow the guide for each exchange the strategy uses.
