Looks like Binance @binancezh is still supporting USD1 consistently. The annualized interest rate for USDT and USDC has been around 2.X, while USD1 has been steadily at 3.X, basically about 1% higher than the other two. Now they've introduced something called AOR (Auto Order Routing). Took a look and here’s a quick summary: 1. Holding USD1 lets you earn relatively higher interest, and you can also get airdrops while holding it. 2. Previously, when trading with USD1, you often had to manually convert it to USDT first before buying your target asset. Too many steps, plus the risk of price differences. Now, for trading pairs that support AOR, you can place orders directly with USD1. The system will automatically compare the direct route and intermediate routing to determine which offers the better price, and handle the conversion in the background for you. No need to split orders yourself or manually swap back and forth. The order interface is still the same familiar one. PS: This feature doesn’t guarantee you’ll always get a better price, nor does it guarantee the entire order will go through the routing. There are also limitations on supported trading pairs and amounts, so you’ll need to check the trading interface for details. For those who hold stablecoins like USD1 to earn interest most of the time, it’s worth checking out.
