Startale Group has partnered with Sunnyside Labs to integrate Privacy Boost into its consumer focused crypto app, bringing optional onchain privacy features to users.
Key Takeaways
- Startale App will integrate Privacy Boost to enable private crypto transactions.
- The solution combines zero knowledge proofs and secure environments for fast and scalable privacy.
- Users will retain self custody while gaining control over transaction visibility.
- The move strengthens Soneium’s position as a consumer friendly blockchain ecosystem.
What Happened?
Startale Group announced a partnership with Sunnyside Labs to make Privacy Boost the official privacy solution for the Startale App. The integration will be deployed directly on Soneium, a blockchain developed by Sony Block Solutions Labs, and marks Privacy Boost’s first entry into a consumer facing platform.
The update introduces optional privacy features into the app, allowing users to control how much of their onchain activity is visible, while still maintaining compliance capabilities.
Every user should have the choice to protect their onchain activity. With @sunnyside_io, now they can.

Startale Pushes Privacy Into Consumer Crypto
The Startale App is designed as an all in one gateway to the onchain economy, offering features like asset management, payments, Mini Apps, and rewards. However, like most public blockchains, transactions are typically transparent, exposing balances, transfer amounts, and wallet interactions.
With Privacy Boost, users can now choose to shield their activity when needed. This includes:
- Moving assets into private pools.
- Conducting private transfers that hide balances and counterparties.
- Enabling privacy focused payment flows for future crypto card use.
This shift reflects a growing demand for privacy in consumer crypto applications, especially as adoption expands beyond early users.
Sota Watanabe, CEO of Startale Group, said:
Technology Behind Privacy Boost
Privacy Boost uses a hybrid system that combines zero knowledge proofs with trusted execution environments. This approach allows transactions to remain private while still being verifiable when required.
Key performance highlights include:
- Proof generation in under 500 milliseconds.
- Throughput of over 1,800 transactions per second.
- Support for selective auditability to meet compliance needs.
The protocol will deploy its full infrastructure on Soneium, including smart contracts and secure execution systems. Developers building on the network will also be able to integrate privacy features directly into their applications.
Taem Park, Co-Founder and CEO of Sunnyside Labs, said:
A Step Toward Mainstream Adoption
The integration highlights a broader industry trend where privacy is becoming a key feature rather than an afterthought. By embedding privacy at the infrastructure level, Startale Group aims to make blockchain technology more practical for everyday users.
As the app expands into new payment systems, Mini Apps, and ecosystem integrations, privacy is expected to play a central role in shaping user experience. This could help address one of the biggest concerns around public blockchains, which is the lack of transactional confidentiality.
CoinLaw’s Takeaway
In my experience, privacy has always been one of the missing pieces in mainstream crypto adoption. Most users are not comfortable with every transaction being visible to the public. What I find interesting here is how Startale is not forcing privacy but making it optional. That balance between transparency and control feels practical and user friendly.
I also believe this move could push other platforms to rethink how they handle user data onchain. If Startale succeeds, privacy could quickly become a standard feature rather than a premium add on.
