OKX's USDG may have shifted from a 1:1 rigid exchange rate to a market rate, but I just checked and the liquidity is still pretty solid. If you use USDT to subscribe to USDG in the Earn section, there’s a slight premium, so you can exchange for a bit more. However, if you use the Swap feature, there’s some slippage. For a 20WU limit, the difference between these two methods is about 50U, so subscribing directly in Earn is more cost-effective. A 4.1% annualized yield for stablecoin investment is already quite high—if you’ve got idle U on hand, it’s worth a try. As for USDG, it’s a compliant stablecoin issued under the joint regulation of Singapore and the EU by an alliance that includes OKX, Kraken, Robinhood, Anchorage, Galaxy, and other institutions. Why does USDG have a higher yield? Unlike USDC or USDT, USDG distributes all the treasury bond yields it holds to its partners. OKX, as a core member of USDG, has priority integration rights and passes on the yields from USDG, adding its own subsidies before distributing them to users.
