Umbra Launches Private Token Vesting in Collaboration with Streamflow

Umbra, Solana-based privacy protocol built on Arcium infrastructure, has launched private token vesting in partnership with Streamflow, enabling teams to vest and distribute tokens confidentially.

The launch comes off the back of strong developer adoption of the Umbra SDK during the Colosseum Frontier Hackathon, which saw over 100 teams build on Umbra’s tech stack.

Privacy coins are showing considerable strength amidst turbulent conditions, with sector leaders like Near Protocol ($NEAR) and Zcash ($ZEC) respectively up 84% and 60% in the last 30D, outperforming the wider market.

Umbra, Streamflow Enable Private Token Vesting

Joining forces with Streamflow, Umbra has enabled confidential vesting infrastructure on Solana, enabling teams and VCs to distribute tokens without publicly revealing sensitive information like asset amounts or wallet addresses.

The integration takes full advantage of Streamflow’s product offering, including time-based locks, price-based conditions, and other token distribution mechanisms. Confidentially-vested tokens are distributed directly to recipients’ Umbra wallet and immediately integrated into its expanding anonymity pool, helping to grow Umbra’s privacy-preserving ecosystem.

“Combining Streamflow’s gold standard vesting infrastructure with Umbra’s privacy layer is a landmark moment for the industry. Umbra couldn’t be more excited to be building this alongside the Streamflow team." - Kru Shah, Umbra Founder

Umbra’s collaboration with StreamFlow, a token distribution company serving over 1.3M users across 40,000 projects, brings privacy to one of crypto’s fastest-growing fields, with over $97B in tokens entering markets through vesting schedules in 2025. 

Meanwhile, confidentiality is something of a polarizing topic among crypto-natives. While some would argue that anonymity is one of the foundational tenets of the industry, others claim that the privacy sector enables tax evasion at unprecedented scale. Concurrently, transparency advocates would argue that trust is only obtainable through publicly verifiable token distribution, which protects investors from vesting obfuscation.

Taking a more realistic approach, social media commentators assert that no VC or team member wants every transaction or transfer to come under public scrutiny. Privacy advocates argue that confidential vesting, like that provided by Umbra and Streamflow, will become a default industry standard in the future.

100+ Teams Built on Umbra in Colosseum Hackathon Sidetrack

Beyond the launch of confidential vesting, Umbra is gaining momentum as an infrastructure partner for emerging applications.

As part of Colosseum’s Frontier hackathon, which saw an all-time high 2857 submissions, Umbra hosted its own sidetrack.

According to Umbra, over 100 teams participated in its hackathon sidetrack, demonstrating strong builder-appetite for onchain privacy protocols. Swish Cash, a confidential payments app, took first place in the Umbra sidetrack, with Seedless and GhostAI coming in 2nd and 3rd, respectively.

$UMBRA Up 40% As Privacy Coins Soar

After spiking to $0.65 on May 26, $UMBRA is currently trading hands at $0.49, up 47.4% on a weekly timeframe.
