Privacy assets can finally generate interest, and 'Confidential DeFi' has officially entered the practical stage. Zama just released the app last week and saw a more substantial step today - the Steakhouse Confidential USDC Prime vault will officially open on Morpho. This is the world's first DeFi revenue vault specifically designed for confidential USDC (cUSDC), curated by Steakhouse Financial and supported by Zama Protocol. Through this vault, cUSDC has truly gained DeFi profitability for the first time. Why is this matter worth mentioning? I have also talked about a very practical pain point on the chain before: confidential assets can achieve privacy (balance and transfer amount encryption), but they have never been able to participate in DeFi to earn profits. Users and institutions either give up profits for privacy or expose their assets on the chain for profit. This leads to "confidentiality" staying in the "holding" stage for a long time, lacking actual capital utility. Today, this vault is online to directly fill this gap. After users shield their assets into cUSDC, they can directly deposit them into the vault to earn profits, completely solving the pain point of "confidential assets cannot generate interest" previously. This is not just a simple online vault, but a true combination of three important elements: 1) Morpho provides mature DeFi infrastructure and liquidity; 2) Steakhouse Financial is responsible for treasury curation and risk control; 3) Zama Protocol provides underlying confidentiality technology support. The combination of the three factors enabled cUSDC to have complete DeFi usage value for the first time. The launch of Zama App has made it easy for users to convert assets into cUSDC, and the opening of this vault has truly evolved cUSDC from being "confidential" to being "both confidential and profitable". Only by combining the two can we truly break through the first closed loop of secure DeFi. After the Q3 confidential exchange function is launched, the trading and liquidity of confidential assets will gradually be connected. It seems that the core task of Zama in 2026 is to continue to integrate these key ecosystems, making the confidentiality layer a standard configuration for on chain finance like a oracle and stablecoin. The Zama App has been launched, and for the first time, cUSDC has been provided with DeFi earning power through Steakhouse's vault on Morpho. Coupled with a 12 week earnings boost event, the APY was the highest at the time of launch, and the earlier and larger the deposit, the greater the boost. This marks that "Confidential DeFi" has truly entered the practical stage. After this node, the usage scenarios of confidential assets on the chain will clearly open up, which is worth focusing on tracking.
