Zama, Morpho, and Steakhouse launch first confidential DeFi yield vault on Ethereum
Three teams just built what might be the missing piece for getting serious money into DeFi: a yield vault where nobody can see how much you deposited.
Zama, Morpho, and Steakhouse Financial have launched what they describe as the first confidential DeFi yield vault on Ethereum. The product lets firms earn yield on USDC deposits while keeping their balances, positions, and strategies fully encrypted, invisible to anyone browsing the blockchain.
How encrypted yield actually works
The core technology here is Fully Homomorphic Encryption, or FHE. Think of it like a locked suggestion box where someone can count the votes without ever opening the individual slips. FHE allows computations to be performed on encrypted data without ever decrypting it first, meaning smart contracts can process lending and yield logic while the underlying numbers stay hidden.
Zama provides the FHE layer that makes confidential smart contract execution possible on Ethereum. Morpho supplies the permissionless lending infrastructure, operating as modular lending primitives where risk is managed through curator-defined allocation strategies. Steakhouse Financial plays the curator role, selecting and managing the vault strategies that focus on blue-chip collateral and real-world assets.
Steakhouse-curated Morpho vaults have reported over $2 billion in total value locked across their products. The APYs for their USDC vaults range between 3.5% and 5.3%, depending on the tier of the vault.
Why privacy is the institutional dealbreaker
Here’s the thing about public blockchains. Every transaction, every balance, every strategy is visible to anyone with an internet connection. For a fund deploying tens of millions, that’s an operational risk. When a large institution takes a position on-chain, competitors can see it in real time. Traders can front-run it. Analysts can reverse-engineer the strategy.
By encrypting balances and positions at the protocol level, the vault removes the information leakage that makes public DeFi unappealing for large allocators. The yield still comes from on-chain lending markets. The settlement is still on Ethereum. The confidentiality is enforced cryptographically rather than by trusting an intermediary.

The AI boom may follow the path of the 19th-century railway bubble, and builders may not be the ultimate winners
Goldman Sachs analyst Bobby Molavi compared the current situation to the 19th-century British railway mania: 500 companies spent more than the nation's annual income building 8,000 miles of railway, with most early investors losing out, while the real beneficiaries were the later "passengers." He pointed out that the current AI craze is driven by both debt and momentum, and that the S&P 500’s forward P/E ratio of 18x is only "a bit cheaper." Whether the builders can retain value is uncertain, and history does not offer an optimistic answer.
If Anthropic's IPO goes smoothly and the stock price rises next week, then everything remains the same for AI. Otherwise, some companies will go bankrupt.
The shrinking valuations of two major giants have triggered a chain reaction—investors are adopting more conservative revenue multiples for AI startups and are directly halting high-valuation financing for companies with zero revenue. Multiple venture capital firms have advised their portfolio companies to lower valuation expectations and to quickly build up cash reserves. Market participants warn that the outcome of Anthropic’s IPO will be a barometer for the industry: if successful, the boom will continue; if it fails, some companies may face elimination.

For Corning, the recent profit growth mainly comes from the expansion of AI clusters. As the number of optical links crossing cabinets and campuses increases, customers need to deploy more optical fibers within limited conduit and cabinet space, thus driving demand for high-density optical cables and connection systems.
