One Market. Deeper Liquidity

Tired of switching between BTC/USD and BTC/USDC? Or forgetting which pair you opened that trade on? We get it. Managing multiple stablecoin pairs just to find the best price or the right market shouldn’t be part of your daily strategy. Every second counts, and every click adds up. That’s why we’ve simplified it for everyone.

Introducing: The Unified USD Orderbook

Now, instead of choosing between pairs like BTC-USD or BTC-USDC, you trade one market. Behind the scenes, OKX handles the routing and conversion, while you get the price and fills efficiently. We didn’t just mirror orderbooks or slap on a prettier design. We rebuilt the engine underneath. Here’s what that gives you:

• True unified liquidity: No more split books or hidden inefficiencies

• Execution transparency: You still hold and settle in your preferred stablecoin

• Fast, tight, and reliable fills: Built for traders, not tourists

For Retail Traders, no more toggling between liquidity pools, or being limited by the markets. One USD Unified orderbook market gives you access to over 270+ spot pairs, boosting both accessibility and liquidity. This means:

• Better pricing, tighter spreads

• Faster fills in volatile markets

• Simple, clean interface for both USD and USDC markets

For Institutional Clients, the unified back and front end means:

• API users now only need to reference [USD] pairs (e.g., BTC-USD) instead of managing multiple stablecoin specific tickers. Settlement preferences, whether USD or USDC can be defined through the [tradequoteCcy] parameter, enabling precise backend handling while preserving user flexibility.

• RFQ flow support coming soon in next phase rollout.

• Smoother execution for large orders, with benefits that comes with enhanced liquidity

Building in a regulated environment, for the future

In jurisdictions like the U.S., Singapore, UAE, and the Bahamas, stablecoin clarity is critical. Our Unified USD Orderbook supports:

• 1:1 redemption paths and regulatory-ready rails

• Multiple stablecoin issuers (today: USDC; coming soon: USDG and more)

• Seamless trade settlement that honors user preference

This makes OKX future-proof, ready for what compliance and scale look like next. Whether you’re trading from your phone at lunch or managing millions via API, the Unified USD Orderbook makes your every move smarter. Fewer steps. Deeper liquidity.
