Progress Update: Building a New Privacy Primitive for Solana

Privacy on Solana is entering a new era.

For a long time, “privacy” in crypto has lived at the edges: slow, expensive, fragile, or limited to ecosystems that don’t match Solana’s speed and composability. We think that’s about to change.

zNinja is being built to make practical, high-throughput privacy feel native to Solana.

The concept (in plain terms)

At the core, we’re building a shielded pool: a way to move value such that the public chain does not reveal the same level of detail you’d normally expect from transparent transfers.

What does that mean for users?

• You can enter the pool.
• You can move value inside the pool.
• You can exit the pool.

And importantly: this is designed to work with Solana’s low latency expectations—without turning every private action into a waiting game.

Where we are right now

We’ve reached the point where the end-to-end flow is working in our development environment:

• Deposits are functioning end-to-end.
• Shielded transfers are working with change handling and robust state sync.
• Withdrawals are working back to transparent recipients.
• The client stack is being tuned for consistency and reliability (the “it just works” feeling matters).

We’re now focused on hardening, performance, and the unglamorous but critical work that turns a prototype into a product.

Why this is significant (and honestly unprecedented on Solana)

Solana is fast because it’s transparent-by-default. That’s a feature—until you need confidentiality.

If we get this right, it unlocks a new design space:

• DeFi without broadcasting your intent
• Payments without leaking your full activity graph
• Better operational privacy for teams, creators, and everyday users

This is not “privacy as an add-on.” This is privacy as a first-class primitive that can coexist with Solana’s throughput.

What we’re not sharing (yet)

We’re intentionally keeping certain implementation details private while we finalize the design and harden the system.

There’s a difference between explaining the concept and handing out a playbook. We’ll open up more as we approach release milestones.

What’s next

Over the coming weeks, our focus is:

• tightening correctness and edge-case coverage
• improving performance and proving ergonomics
• preparing the rollout path so early users can test without friction

We’ll keep publishing updates here as we move from “working” to “ready.”

Token + open source

The zNinja token is coming soon.

After the token launch, we plan to open source the entire project. We want the community to be able to verify, extend, and build on what we’re shipping.

If you’ve been waiting for Solana-native privacy that feels real—not theoretical—this is the moment. A new paradigm is emerging, and we’re excited to build it with you.
