USDT goes confidential on Zama as shielded stablecoin volume crosses $131M

Tether’s USDT is now live on Zama, the onchain confidentiality protocol that uses fully homomorphic encryption to shield transaction amounts and balances from prying eyes on public blockchains. The integration converts standard USDT into a confidential version called cUSDT, letting users transact on Ethereum without broadcasting their financial details to the entire network.

What Zama actually does

Zama’s protocol uses the ERC-7984 standard to wrap public ERC-20 tokens into confidential versions through a two-transaction process. The wrapped tokens, cUSDT in this case, keep transfer amounts and balances encrypted while preserving the composability and verifiability that make DeFi functional.

As of mid-September 2026, cUSDT has recorded a cumulative shielded volume of $131.3 million. The current shielded total value locked sits at $7.7 million. For a protocol that only executed its first confidential USDT transfer in January 2026, that adoption curve is steep.

Since then, Zama has rolled out a swap protocol that lets users exchange cUSDT with other confidential tokens. On September 15, Zama added 16 confidential Morpho vaults to its roster, including products denominated in cUSDT. Steakhouse Financial backed the expansion. The first of these vaults hit $40 million in TVL within seven weeks of its June 2026 debut.

Why privacy matters for stablecoins

Every Ethereum transaction is visible to anyone with a block explorer. For corporate treasuries moving millions, that transparency is a dealbreaker. Competitors can monitor your payment flows. Traders can front-run your large orders. Counterparties can gauge your exact financial position before sitting down to negotiate.

Global stablecoin settlements surpassed $33 trillion in 2025. Fully homomorphic encryption allows computations to be performed directly on encrypted data. The blockchain can process transactions, check balances, and enforce rules without ever decrypting the actual numbers.

The $ZAMA token and ecosystem growth

Zama launched its native $ZAMA token in February 2026 through a Dutch auction that shielded over $121 million in value. The token captures protocol fees from confidential transactions and acts as a staking asset for network operators who run the encryption infrastructure. Listings on prominent exchanges followed the auction, and Revolut integrated $ZAMA, giving the token exposure to the fintech platform’s retail user base.

The 16 new Morpho vaults mean that yield-seeking capital can now earn returns without exposing position sizes or strategies to the public. Adding confidential vaults on Morpho, the decentralized lending protocol, extends the ecosystem into institutional DeFi strategies.

What to watch from here

The $7.7 million in shielded TVL is respectable for a protocol less than a year into live operations. Zama’s approach of wrapping regulated stablecoins like USDT, rather than creating anonymous native currencies, positions it more favorably on the compliance spectrum. Tether itself has been cooperating with law enforcement agencies, and a confidential wrapper that still allows authorized audits could thread the needle between privacy and regulatory acceptability.

The $131.3 million in cumulative shielded volume demonstrates real usage, not just speculative token activity.
