# LTP and Bybit

> LTP opens the Bybit sub-account and creates its two API keys; you whitelist them and enter them in Blockhouse.

**1. Get your Bybit sub-account and keys**

Ask your LTP account manager to provision a [DMA sub-account](https://docs.blockhouse.app/reference/glossary.md#dma-sub-account) on Bybit for this strategy, set to a Unified Trading Account in Cross Margin mode, with one-way mode, with two separate API keys: a read-only key and a trading key. LTP creates the keys on Bybit and sets their permissions.

**2. Whitelist and enter the read-only key**

In Blockhouse, on the **Bybit** tab of the Credentials step, choose **Copy** → **Comma** on the **Read-only API IPs**.

In the LTP client, open **Account** → **API Management** and find the read-only key on your Bybit DMA sub-account. Edit its IP whitelist and paste the IPs. Reveal its secret, which LTP shows only once, and paste the key and secret into **Read-only API Key** and **Read-only API Secret** in Blockhouse, with the key's passphrase on OKX and Bitget. Tick **IPs are whitelisted for read-only API**.

**3. Whitelist and enter the trading key**

In Blockhouse, choose **Copy** → **Comma** on the **Trading API IPs**. Then whitelist the trading key in **API Management** the same way, and paste it into **Trading API Key** and **Trading API Secret**. Tick **IPs are whitelisted for trading API**.

**4. Finish in Blockhouse**

Copy the 5-digit **accountId** of your Bybit DMA sub-account from the LTP client, or ask your account manager for it. Use this ID, not the UID Bybit assigns. In Blockhouse, on the **Bybit** tab, enter it in **LTP account ID for Bybit**.

Check that every key field on the tab is filled in and both IP boxes are ticked. Set up any other exchange from the [LTP guide](https://docs.blockhouse.app/open-an-account/connect-your-exchanges/prime-brokers/ltp), then [submit the Credentials step](https://docs.blockhouse.app/open-an-account/connect-your-exchanges).
