Recently, the Sui ecosystem has been really intense. Coinbase officially announced support for the Sui token standard, followed quickly by DEEP and WAL both launching, instantly boosting liquidity. Then Ethena Labs teamed up with Sui, and suiUSDe officially entered the mainnet, igniting the "interest-bearing USD" sector of Sui DeFi in an instant.

In simple terms, suiUSDe is a synthetic USD tailored for Sui. It inherits Ethena's delta-neutral mechanism, backed by staked assets plus perpetual hedging, naturally earning interest, so holding it can earn basic yields. Compared to traditional stablecoins, it has an extra layer of "self-growing" property.
What really made me excited is the chemical reaction between it and DeepBook.
@DeepBookonSui Margin launched support for suiUSDe on its first day, embedding its interest-earning capability directly into the order book. You can:
Use suiUSDe as collateral to open leveraged long or short positions; earn interest while providing liquidity, earning double;
Even use it in margin pools to play more complex strategies.
This series of operations seamlessly combines "passive income + active trading," transforming DeepBook from a simple CEX-level DEX into a "profit engine" within DeFi.
Even better, suiUSDe is now seamlessly integrated with top protocols like Navi, Scallop, Suilend, Bluefin, Ember, and others. Simply holding it allows you to earn Ethena's base interest, and depositing it further stacks with Sui's native high APY, with yields skyrocketing.
I’ve already shifted part of my position into suiUSDe, and the feeling is: finally, there's a USD asset on Sui that is stable, income-generating, and leveragable.
This move by Sui is truly showing everyone with real action: high performance isn’t just about TPS, but about truly composable finance.
