Umbra, the Solana-native privacy layer, has partnered with leading token distribution platform Streamflow to launch confidential token vesting, a product aimed at the estimated $97 billion cryptocurrency token unlock market. The integration encrypts vesting schedules, allocation amounts, and recipient wallet addresses, preventing the on-chain surveillance that allows front-running of insider allocations.
Built on Arcium’s encrypted execution engine, the solution processes vesting operations over fully encrypted data using multi-party computation. The recipient’s identity, allocation size, and unlock timeline remain encrypted at the contract level, while actual token transfers settle transparently on Solana without exposing the underlying parameters to public mempools or analytics tools. Streamflow, recently committed to operating exclusively on Solana, serves more than 1.3 million users and over 40,000 projects and offers no-code tools for vesting, token locks, airdrops, and staking. Clients can access the integration through a standard track with preferential pricing or a custom track for high-volume requirements.
Standard vesting contracts on public ledgers allow anyone to see which wallets will receive tokens, exact amounts, and unlock schedules, giving sophisticated traders structural advantages that disadvantage projects and holders. The new private vesting eliminates that information asymmetry. “Onchain privacy is the next frontier we need for further mainstream adoption,” said Streamflow CEO Malisha Stanojevic. Umbra founder Kru Shah called the partnership “a landmark moment for the industry.”
Umbra itself opened its public privacy wallet in March 2026 and raised $154.9 million in USDC commitments from over 10,518 participants via MetaDAO’s ICO framework in October 2025, making it one of the most successful raises on that platform. The confidential vesting launch extends the protocol’s privacy infrastructure from individual transactions into corporate treasury and investor management, the area where the largest on-chain unlock volumes are concentrated.
