Tired of switching between USD, USDC or USDG pairs? 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, BTC-USDC, or BTC-USDG, you trade a single USD 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 means for you:

True unified liquidity: Across USD, USDC, and USDG
Execution transparency: You still hold and settle in your preferred stablecoin
Fast, tight, and reliable fills: With tighter spreads and less friction
All the flexibility: No more switching

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

Deeper liquidity and tighter spreads
Faster fills in volatile markets
A clean, simplified experience—regardless of which stablecoin you use

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

API users now only need to reference just one ticker (e.g., BTC-USD) instead of managing multiple stablecoin-specific tickers.
Settle in your preferred asset (USD, USDC or USDG) via the [tradequoteCcy] parameter.
RFQ flow support coming soon in next phase rollout.
Smoother execution for larger orders.

Building in a regulated environment, for the future

In markets like the U.S., Singapore, Brazil, Australia, Türkiye, UAE, and the Bahamas—regulatory clarity around stablecoins is shaping the future.

Our Unified Orderbook is designed for that future:

Full 1:1 redemption and compliance-aligned rails
Support for multiple regulated stablecoins (today: USDC and USDG, more coming)
Transparent, preference-driven settlement—without compromising on performance

Whether you’re trading casually on mobile, or routing millions through an institutional desk, the Unified USD Orderbook makes every move smarter, faster, and more powerful.

Welcome to OKX’s Unified Orderbook.
