Umbra and Streamflow have launched a private token vesting integration on Solana, allowing projects to distribute vested tokens with greater confidentiality.
The integration combines Umbra’s privacy layer with Streamflow’s token distribution and vesting infrastructure. It is powered by Arcium’s encrypted execution engine and enables token transfers linked to vesting schedules to take place privately.
Projects using Streamflow will still be able to use existing features such as time-based locks, price-based conditions, and other distribution mechanisms. Recipients will receive vested tokens through Umbra wallets within a privacy-preserving environment.
The companies said the service will be available through two tracks: a standard option with default pricing terms and a custom option for larger or more specialized requirements.
Token vesting is widely used by crypto projects to manage allocations for teams, investors, and communities. According to the companies, about $97 billion in tokens were released through vesting and unlock schedules in 2025, most of them through publicly traceable on-chain transactions.
The launch reflects increasing demand for privacy tools in token distribution, particularly as projects seek to manage vesting, liquidity, and stakeholder allocations without exposing all transaction details publicly.
Streamflow says it serves more than 1.3 million users and over 40,000 projects on Solana. The partnership gives its clients access to private vesting infrastructure through Umbra’s privacy layer.
