Zama Opens 16 Confidential Morpho Vaults on Ethereum

Encrypted Lending Goes From One Vault to Sixteen

Zama opened deposits on 16 confidential Morpho vaults on Ethereum on September 15, 2026, and launched a companion swap protocol that lets users trade between encrypted assets without revealing size or intent. The expansion follows a single pilot vault launched in June, which Zama says went from zero to more than $40 million in shielded total value locked in seven weeks.

• Vaults live: 16 total — 12 existing Morpho vaults that now accept confidential deposits, plus 4 built as confidential-only products
• Curators: Steakhouse Financial (5 vaults), Armitage by Wintermute (6), Flowdesk (2), RockawayX (2) and Bitwise (1)
• Assets: USDC, USDT, WBTC, AUSD and TGBP, each with a confidential counterpart
• New protocol: the Zama Confidential Swap Protocol, for swapping between encrypted assets and vault positions on Ethereum

How Does Confidential DeFi Work on a Public Chain?

The mechanism is fully homomorphic encryption, and it is worth being precise about what it does. FHE allows arithmetic to be performed directly on encrypted values without decrypting them first. Applied to a lending vault, that means the smart contract can run its deposit accounting, compute yield and settle positions while the underlying numbers stay encrypted on a fully public chain.

The practical consequence is a change in what an observer can see. Ethereum's transparency has always been a double-edged property for anyone moving size: the ledger is auditable by design, which is excellent for verification and actively hostile to anyone whose position would be front-run the moment it appears in a mempool. FHE-based vaults let the settlement remain verifiable while the amounts do not become public information.

The swap protocol extends that to the trade itself. Depositors can move between confidential stablecoins and vault shares without disclosing transaction size — closing the gap that would otherwise leak position information the moment someone exited.

Who Is Curating These Vaults, and Why Does That Matter?

Vault curation is where the credit risk actually sits, so the names matter more than the encryption headline. Five curators are live at launch, and the mix is notable: Steakhouse Financial and RockawayX are DeFi-native, Armitage is the on-chain arm of market maker Wintermute, Flowdesk is a market-making and liquidity firm, and Bitwise is an asset manager better known for exchange-traded products.

That is a reasonably institutional lineup for a privacy-focused product, and it tracks with the direction of travel for curated lending generally. We looked at the curated-vault model earlier this year when Stable launched an institutional RWA yield product on Morpho, and the same structural question applies here: encryption protects position privacy, it does not underwrite the strategy behind the vault.

Zama also says it is running its first confidential incentive campaigns on Merkl using the ERC7984 standard, and that distribution partners including Utila, Zerion Wallet and Yield.xyz will roll out support in the weeks ahead.

The Bigger Picture for On-Chain Privacy

This is the second significant distribution milestone for Zama's FHE stack in as many months. In August we covered the company bringing FHE privacy tokens to Revolut's user base, which put the technology in front of a mainstream consumer audience for the first time.

The strategic read is straightforward. Confidential DeFi has been a research topic for years, and the constraint has never really been cryptography — it has been whether anyone would put real capital behind an encrypted position. A single vault crossing $40 million in seven weeks is a small number by DeFi standards and a meaningful one as a proof point. Sixteen vaults across five asset types with five named curators is the follow-up test. Whether shielded TVL keeps compounding from here is the number to watch over the next quarter.
