[Solana Privacy Layer Umbra Partners with Streamflow to Launch Private Token Vesting Service] Odaily Planet Daily News: Solana privacy layer Umbra has partnered with token distribution platform Streamflow to introduce a private token vesting feature, enabling projects on Solana to achieve token locking, vesting, and distribution with enhanced privacy. This solution is powered by Arcium's cryptographic execution engine. Streamflow users can still utilize existing distribution mechanisms based on time locks, price conditions, and more, but the actual token transfer process will remain private. Recipients will directly receive vested tokens 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 this product primarily addresses risks such as on-chain monitoring, frontrunning, and information asymmetry during the token unlocking process. In 2025 alone, the scale of tokens released through vesting and unlocking plans is estimated to reach approximately $97 billion, while most related data can still be publicly tracked on-chain. Streamflow currently serves over 1.3 million users and more than 40,000 projects, making it one of the primary token distribution platforms in the Solana ecosystem. This collaboration also reflects that on-chain privacy is gradually becoming a critical infrastructure for large-scale token distribution and driving mainstream adoption.
