Once BIT has created the keys, check each Bitget setting below before the strategy starts, even if BIT carried some over from your main account.
The strategy trades on Bitget’s Unified Trading Account. If the sub-account is still a Classic account, the first step below upgrades it. The upgrade can’t be undone.

In Blockhouse, on the Bitget tab of the Credentials step, choose Copy → Comma on the Read-only API IPs, and again later on the Trading API IPs.In the BIT Prime Brokerage portal, open Accounts → Open Account. On the CEFI tab, choose Application next to Bitget, then set:
  • Custody: Bitget with no external Custody
  • Account’s Api: Authorize BIT to create your API
Choose Add twice, once for each key, and fill them in:Account Notice is where BIT sends the new key, and Binding IP address takes up to 10 addresses, comma-separated. Choose Confirm and complete the verification.
The other custody options, such as 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): confirm both with your BIT contact.

Enter the keys in Blockhouse

BIT usually creates the keys within a day. When it sends them to your authorized email, copy each key’s API key, secret and passphrase into the matching fields on the Bitget tab in Blockhouse, and tick IPs are whitelisted for read-only API and IPs are whitelisted for trading API.

Upgrade to the Unified Trading Account

In the sub-account, open the wallet icon (top right) → Assets. If you see Upgrade to unified account, choose it, then choose Upgrade once Bitget confirms the account is eligible. Transfers and trading pause for about a minute while it upgrades. If there’s no upgrade banner, the sub-account is already on the Unified Trading Account.
