Deposits, Transfers & Withdrawals

BBX deposits, withdrawals, and transfers between accounts are centered around the Funding Account.

Assets deposited from an external wallet will first be credited to the BBX Funding Account. When users need to access different types of trading, they can then transfer assets from the Funding Account to the corresponding Futures Account, Spot Account, or Stock Account.

For withdrawals, if the assets are currently held in a trading account, they must first be transferred back to the Funding Account before being withdrawn to an external destination address.

Currently Supported Deposit & Withdrawal Networks and Assets

BBX currently supports deposits and withdrawals through the following blockchain networks:

Blockchain Network	Supported Assets
Arbitrum One	USDT, USDC
Ethereum Mainnet	ETH, USDT, USDC
BNB Smart Chain (BSC)	BNB, USDT, USDC
Bitcoin Network	BTC

When making a deposit or withdrawal, please select the appropriate blockchain network based on the network where your assets are held, and make sure the asset, network, and address match.

Minimum deposit/withdrawal amounts, fees, and processing times may vary by network and asset. Please refer to the information displayed on the relevant BBX deposit or withdrawal page and the current status of the corresponding blockchain network.

BBX may continue to add new blockchain networks and supported assets. Please refer to the deposit and withdrawal pages for the latest supported options.

Deposit Flow

When users deposit assets to BBX, the assets will first be credited to the Funding Account.

The basic flow is as follows:

External Wallet
      ↓
Deposit to BBX Funding Account
      ↓
Transfer between accounts based on trading needs
      ↓
Futures Account / Spot Account / Stock Account

Once the deposit has been credited, users can view the corresponding asset balance in the Funding Account.

Depending on the type of trading:

• For perpetual futures trading, transfer the required assets from the Funding Account to the Futures Account;

• For spot trading, transfer the required assets from the Funding Account to the Spot Account;

• For stock trading, transfer the required assets from the Funding Account to the Stock Account.

Transfers Between Accounts

BBX supports asset transfers between the Funding Account and each trading account, as well as between the Spot Account and the Futures Account. Please note that transfers between the following accounts are on-chain transfers:

Funding Account ↔ Futures Account
Funding Account ↔ Spot Account
Funding Account ↔ Stock Account

Therefore, the above account transfers may involve:

• On-chain network fees

• Minimum transfer amount

• Transfer fees

• On-chain confirmation and arrival time

Specific requirements may vary by asset and network.

The applicable minimum transfer amount, fees, and estimated arrival time are subject to the information displayed in the transfer window and the actual on-chain data of the corresponding blockchain.

Withdrawal Flow

All BBX withdrawals are initiated from the Funding Account.

If the asset to be withdrawn is currently held in the Futures Account, Spot Account, or Stock Account, it must first be transferred back to the Funding Account before a withdrawal can be initiated.

The basic flow is as follows:

Futures Account / Spot Account / Stock Account
              ↓
Transfer back to Funding Account
              ↓
Withdraw from Funding Account
              ↓
External Destination Address

For example, if the assets are currently held in the Spot Account, users must first complete:

Spot Account → Funding Account

Once the on-chain transfer has been credited, users can then initiate a withdrawal from the Funding Account to an external address.

Before initiating a withdrawal, please confirm that:

• The assets to be withdrawn have already arrived in the Funding Account;

• The withdrawal asset matches the selected blockchain network;

• The destination address is correct and supports the selected network;

• The withdrawal amount meets the minimum withdrawal requirement for the relevant asset and network;

• You have reviewed the applicable fees and estimated arrival information displayed on the withdrawal page.

Important Notes

• Assets deposited from an external address will first be credited to the Funding Account and will not be deposited directly into the Futures Account, Spot Account, or Stock Account.

• Before withdrawing, if the assets are held in a trading account, they must first be transferred back to the Funding Account.

• When making deposits, withdrawals, or transfers between accounts, please carefully verify the asset, network, and address.

• Different blockchain networks are not directly interchangeable. Selecting the wrong network or address may result in assets not being credited correctly or even permanent loss of assets.

• Minimum amounts, applicable fees, and processing times for deposits, withdrawals, and transfers between accounts are subject to the information displayed on the relevant operation page and the actual status of the corresponding blockchain.
