Umbra and Streamflow Bring Private Token Vesting to Solana in Push for Institutional-Grade Privacy

Umbra and Streamflow have launched encrypted token vesting on Solana (SOL), giving projects a way to distribute locked tokens without publicly exposing recipient wallets, unlock schedules or allocation sizes.

The integration is powered by Arcium’s encrypted execution engine and connects Umbra’s privacy layer with Streamflow’s token distribution platform. It lets teams keep using time-based locks, price-based conditions and other vesting mechanisms while making the actual transfers confidential.

The target market is large. The companies said roughly US$97 billion (AU$134.83 billion) in tokens were released through vesting and unlock schedules in 2025, with most of that activity fully visible onchain.

Vesting Goes Private

Public vesting allows traders to monitor recipient wallets, upcoming unlocks and allocation sizes, then position ahead of expected selling or liquidity changes.

Umbra’s design sends vested tokens directly into Umbra wallets. Each new vesting schedule contributes to a shared anonymity pool, which the teams say strengthens privacy for users and applications building on the network.

It applies confidentiality to a recurring institutional workflow where teams, investors and contributors often receive tokens under predictable schedules.

Streamflow brings the distribution base. The platform serves more than 1.3 million users and over 40,000 projects, offering no-code vesting, token locks, streaming, airdrops and staking tools, and has committed to operating exclusively on Solana.

The commercial pitch is aimed at teams that want public settlement without exposing every internal treasury or investor schedule to the market. Clients can use a standard track with preferential default pricing or a custom track for higher-volume and specialised requirements.

The launch changes what outside market watchers can see onchain, reducing surveillance and front-running risk around large distributions.

That privacy layer is becoming more relevant as Solana attracts larger token launches and institutional workflows.
