Umbra and Streamflow have launched private token vesting on Solana, allowing projects to vest and distribute tokens confidentially at scale, the companies told The Block exclusively.
Powered by Arcium's encrypted execution engine, the integration lets Streamflow clients keep access to the platform's time-based locks, price-based conditions, and other distribution mechanisms while keeping the actual token transfers private.
Recipients receive vested tokens directly into Umbra wallets, with each new vesting schedule contributing to Umbra's shared anonymity pool — strengthening privacy for all users and applications building on the network. "A landmark moment for the industry," Kru Shah, founder of Umbra, said of the partnership.
