Umbra has partnered with Streamflow to bring private token vesting and distribution to Solana, giving projects a way to send vested tokens without exposing transfer details onchain.
The integration uses Umbra’s privacy layer and Arcium’s encrypted execution engine to let Streamflow clients distribute tokens into shielded Umbra wallets. Arcium has been building confidential token infrastructure for Solana, including encrypted transfers and confidential token standards designed to keep transaction data private while still operating onchain.
Streamflow clients will retain access to vesting features such as time based locks, price based conditions, and programmable distribution mechanisms, while the token movement itself occurs privately. Streamflow’s platform supports token vesting, airdrops, staking, token locks, token mints, and token distribution contracts across Solana.
Recipients will receive vested tokens directly into Umbra wallets, adding each private vesting schedule to Umbra’s anonymity pool. The companies said the structure is meant to improve privacy guarantees as more projects and assets move into the shielded ecosystem.
The partnership includes two tracks for Streamflow clients. A standard track will offer preferential default pricing for most teams, while a custom track will target larger volume or specialized distribution needs. Umbra said several high volume discussions are already active, with additional announcements expected.
