[April 21, 2026] Spot Trading: preSPAX (Pre-IPO SpaceX) Trading Pair Now Available

Dear API Developers,

The Spot Trading module officially launched preSPAX on April 21, 2026. To ensure your trading programs (e.g., market data retrieval, order placement, and asset management) operate correctly, please note the following field definitions:

• symbol (trading pair name) — all uppercase, e.g. PRESPAXUSDT
• coin / baseCoin (currency name) — mixed case, e.g. preSPAX

Examples:

• When retrieving market data (e.g. GET /api/v3/market/ticker) or placing orders (e.g. POST /api/v3/trade/place-order), the symbol parameter must be PRESPAXUSDT.
• When querying account balance or asset details, the coin field must be passed in or returned as the mixed-case preSPAX.
