The returns on USDD are truly incredible. Settling every hour, compared to Alipay's annualized rate of 1.3%-1.4%, USDD offers a straight 10%, which means if you earn 1 yuan by depositing in Alipay, you can earn 6 yuan by depositing in USDD.

Specifically, if you deposit 100,000 yuan, the hourly income is 1 USDD. Over a day with 24 hours, that's 24 USDD; in a month of roughly 720 hours, it amounts to about 720 USDD. Converting to RMB, that's over 5,000 yuan; over a year, it totals 8,640 USDD, roughly 60,000 RMB. This comparison is indeed attractive.

I've tried it myself, focusing on three main experience points:

**No slippage during exchange.** USDT and USDD can be exchanged 1:1, and transferring USDD to sUSDD is also very smooth with no loss. The number of sUSDD may appear to decrease, but that's because the value itself is increasing; when redeeming, you'll get more, not less.

**Gas fees are surprisingly cheap.** I conducted two swap tests (USDT→USDD, then USDD→sUSDD), costing only about $0.5 to $1 in total, with just 0.0001 to 0.0002 ETH needed. For Ethereum users, the cost is really low.

**The yield structure has two parts.** The base annual rate is 12%, which remains competitive in the market. Additionally, there are daily activity rewards, distributing 10,000 USDD each day, allocated based on each user's TVL share—the earlier you join, the more rewards you get. Currently, the total TVL of the protocol has surged past $190 million, and the ecosystem continues to grow.

Participation is actually very simple. Open your wallet app, find the corresponding liquidity mining product in the yield module, subscribe to the 【USDT - sUSDD】 trading pair, with a minimum of 100 USDT to start, and begin earning interest after just one hour. It's that easy.
