Svmuu News: Solana privacy layer Umbra has partnered with token distribution platform Streamflow to launch a private token vesting feature, allowing project teams to lock, vest, and distribute tokens on Solana with enhanced privacy. Powered by Arcium’s cryptographic execution engine, the solution enables Streamflow clients to continue using existing distribution mechanisms—such as time locks and price conditions—while ensuring that the actual token transfer process remains private. Recipients will receive vested tokens directly in their Umbra wallets, and each new vesting plan will be added to Umbra’s shared anonymity pool, thereby enhancing overall network privacy. Both parties stated that the product primarily addresses risks associated with on-chain monitoring, front-running, and information asymmetry during the token unlocking process. In 2025 alone, the value of tokens released through vesting and unlocking plans is estimated to reach approximately $97 billion, yet most of the relevant data remains publicly traceable on-chain. Streamflow currently serves over 1.3 million users and more than 40,000 projects, making it one of the leading token distribution platforms in the Solana ecosystem. This collaboration also reflects how on-chain privacy is increasingly becoming a critical infrastructure for projects conducting large-scale token distributions and driving mainstream adoption.
