Stablecoin Stock Trading

BBX Stablecoin Stock Trading aims to provide an extremely convenient, seamless channel for global users. Users can capture investment opportunities in traditional global stock markets with just one click using USDC/USDT, without the need to open a traditional account, thereby avoiding complex and lengthy deposit wait times.

This module provides a smooth experience similar to a Centralized Exchange (CEX) and currently supports trading for nearly 200 popular US and Hong Kong stocks.

Core Mechanism

The BBX Global Stock business perfectly integrates the rigor of traditional finance with the transparency of blockchain technology:

• Partner Broker System Execution: Every stock buy/sell order initiated by a user on BBX is genuinely matched and executed by BBX's partnered traditional compliant broker system on physical exchanges. Real-time market depth synchronization ensures professional and fair trade execution.

• Stablecoin Deposits/Withdrawals, Multi-Currency Trading: Users use stablecoins (USDT/USDC) for lightning-fast deposits and withdrawals, completely eliminating the long waits and high costs of traditional fiat cross-border currency exchange. After entering the stock account, users can flexibly allocate different currencies for multi-market trading according to their needs.

• On-Chain Trading Certificates: Although the underlying stocks are securely custodied within the centralized broker system, every transaction made by the user will synchronously generate a unique on-chain certificate. Asset movements are truly traceable, using blockchain transparency to safeguard your traditional asset investments.

Trading Flow: Deposit, Transfer, and Trade

To start global stock investing on BBX, simply follow these three steps:

1. Fund Account Deposit

On the BBX Portfolio page, deposit your stablecoins (currently supporting USDT / USDC) via the Arbitrum chain into your [Fund Account].

2. Transfer to Stock Account

After the deposit is complete, select "Transfer" to move your stablecoins from the [Fund Account] to the [Stock Account] (funds enter as USD by default).

• Trading US Stocks: Directly use the USD assets in the account to trade.

• Trading HK Stocks: On the specific target asset's trading page, manually convert funds to HKD to proceed with the trade.

3. Start Trading

Enter the [BBX Stock Trading Panel] and select the corresponding US or HK stock target to place an order directly.
