Umbra, the privacy layer for Solana that enables confidential transfers, encrypted balances, and shielded wallets, announced a private vesting partnership with Streamflow, the leading token distribution and vesting platform on Solana. Powered by Arcium’s encrypted execution engine, Umbra’s privacy-preserving confidentiality layer now allows Streamflow clients to vest and distribute tokens privately.
This integration allows projects to retain full access to Streamflow’s time-based locks, price-based conditions, and other distribution mechanisms, while the actual token transfers occur privately. Recipients then receive vested tokens directly into Umbra wallets inside the privacy-preserving ecosystem. Every private vesting schedule contributes to Umbra’s growing anonymity pool, strengthening privacy guarantees for all users and applications building on the network.
The partnership offers Streamflow clients two engagement tracks:
- A standard track with preferential default pricing for the majority of teams
- A custom track for larger-volume or specialized requirements, with several high-volume conversations already active and further announcements expected soon.
Kru Shah, Founder of Umbra, said, “Combining Streamflow’s gold standard vesting infrastructure with Umbra’s privacy layer is a landmark moment for the industry. Umbra couldn’t be more excited to be building this alongside the Streamflow team.”
Token vesting remains the primary mechanism crypto projects use to align incentives with teams, investors, and communities. In 2025 alone, roughly $97 billion in tokens were released through vesting and unlock schedules, nearly all of them fully public and traceable on-chain. Streamflow clients now have access to Umbra’s private vesting infrastructure, with preferential pricing terms making it the most attractive way to distribute tokens privately. Each project that chooses to vest privately further improves Umbra’s shielded pool TVL, enabling deep liquidity to a wide variety of SPL tokens.
Malisha Stanojevich, CEO at Streamflow, said, “Onchain privacy is the next frontier we need for further mainstream adoption, and we’re proud to be pioneering this together with Umbra and Arcium!”
The partnership addresses growing demand for privacy-preserving tools as token distribution becomes more sophisticated and projects seek greater confidentiality in how they deliver tokens. Streamflow is the leading platform for token distribution on Solana, serving more than 1.3 million users and over 40,000 projects. The partnership positions Umbra as Solana’s institutional privacy layer by powering the first confidential token distributions for projects at scale.
