Umbra and Streamflow have launched private token vesting on Solana, enabling projects to distribute tokens confidentially at scale. The feature targets the $97B token unlock market, aiming to enhance privacy for token distributions.

Curvy Protocol has launched on mainnet, enabling multichain private transactions with ease of use. The protocol allows users to receive payments without revealing their balance or transaction history. This development brings production-ready privacy infrastructure to on-chain payments.

Umbra has shut down its front end to prevent hackers from exploiting its system, but the company acknowledges that its smart contracts and open-source front end can still be used by others.
