Key Highlights
- Zama has launched the Steakhouse Confidential Prime USDC vault on Morpho.
- The vault accepts confidential USDC (cUSDC) instead of traditional USDC.
- A 12-week boosted yield program begins on June 24.
Confidential blockchain protocol Zama has launched the Steakhouse Confidential Prime USDC vault on Morpho, introducing what it describes as the first yield-generating DeFi venue for confidential USDC (cUSDC).
According to the official release, the vault opened for deposits on June 23 and allows users to earn yield from Steakhouse Financial’s Prime USDC strategy while keeping individual balances and allocations private onchain. The launch marks Zama’s latest effort to bring confidentiality to decentralized finance through fully homomorphic encryption (FHE)-powered infrastructure.
What makes the cUSDC vault different
The new vault mirrors the existing Steakhouse Prime USDC vault on Morpho but replaces standard USDC deposits with confidential USDC (cUSDC).
According to Zama, users depositing cUSDC receive confidential vault shares that represent ownership of their position without publicly revealing their individual balances. While observers can see the total amount deposited in each batch, they cannot determine how much any individual user contributed.
“For the first time, users can earn yield from a leading DeFi strategy without exposing their balances and allocations onchain,” Zama said.
The company emphasized that the batching mechanism is not a mixer. Instead, all deposits are allocated into the same underlying strategy while ownership remains represented through confidential vault shares.
“This means the destination and ownership of funds remain transparent and auditable, while individual balances and positions are confidential,” the company explained.
12-week yield boost program begins June 24
To encourage early participation, Zama is launching a 12-week incentive program beginning on June 24. The rewards will be distributed on top of the vault’s native yield, which currently generates approximately 4% annualized returns through the underlying Steakhouse Prime USDC strategy on Morpho.
The program has been structured in three phases:
- Launch Pulse (Weeks 1-2)
- Mid Pulse (Weeks 3-6)
- Late Pulse (Weeks 7-12)
According to Zama, the highest rewards will be distributed during the Launch Pulse phase.
“Deposits made today are in the vault from day one of the boost,” the company said. The incentive mechanism distributes rewards directly into the vault during each batch cycle, with allocations shared proportionally among participating liquidity providers.
Why early depositors could earn more
Zama noted that timing plays a significant role in determining overall returns. Users who deposit earlier gain access to more reward distributions and potentially larger yields due to lower total value locked (TVL) during the early stages of the program.
“The launch pulse is when both the daily drip is highest and TVL is lowest,” Zama explained. “That combination is what makes early entry materially higher-yielding than later entry.”
As more capital enters the vault, reward distributions are spread across a larger asset base, reducing per-dollar returns for later participants. After the 12-week incentive campaign concludes, users will continue earning the vault’s native yield generated through Morpho’s lending strategy.
Built on Morpho’s existing infrastructure
The vault utilizes the same risk parameters and lending markets as Steakhouse Prime USDC on Morpho. Underlying collateral includes assets such as cbBTC, WBTC, and wstETH deployed through Morpho Blue markets. The only difference is the confidential nature of deposits and ownership records enabled through Zama’s privacy technology.
The company described the launch as the first version of its broader Confidential Vault stack, with future upgrades expected to improve capital efficiency and expand privacy-preserving DeFi functionality.
Zama expands vision for confidential finance
The launch follows Zama’s announcement earlier this month of its partnership with Morpho and Steakhouse Financial to create the first DeFi yield venue for confidential stablecoins. The company views the vault as a foundational building block for a broader ecosystem of confidential financial applications.
“This launch is the first step toward a broader confidential finance stack, with support for additional assets, chains, and applications to come,” Zama said.
As institutions and retail users increasingly seek privacy-preserving financial tools, the company believes confidential assets could become a key component of next-generation DeFi infrastructure. With Steakhouse Confidential Prime USDC now live, Zama has taken a significant step toward bringing privacy-enhanced yield generation to the growing onchain economy.
