Helius Launches Privacy Rings for Solana Asset Encryption

By Nathan Brooks

Helius deployed Solana Privacy Rings on Nov. 10, according to the company’s launch disclosure, giving Solana app developers a mainnet tool to encrypt transaction assets and amounts while leaving wallet addresses visible. The release encrypts confidential transaction fields on-chain but does not make wallet participants anonymous.

That distinction defines the protocol’s operating limit. Programmable pools keep asset and amount details encrypted on-chain, while wallet addresses stay public. Users can reveal balances with viewing keys, creating a controlled disclosure path without returning every transaction field to public view.

Mainnet scope and integrations

Helius provides an API that developers can add to new or existing Solana applications. The supported asset set is:

• SOL
• SPL tokens
• Token-2022

Helius reports that zero-knowledge proof verification takes hundreds of milliseconds. That is the disclosed verification time, not a broader measure of end-to-end transaction processing, which the launch material does not benchmark.

Three auditors—Certora, OtterSec and ZK Security—have audited the core programs and proof circuits. The announcement identifies their review scope but provides no findings, so it does not support conclusions about remediation status or implementation risk.

Integration status differs across the Solana ecosystem:

• Ore has completed an integration.
• Backpack is working on an integration.
• DFlow is working on an integration.
• Jupiter is working on an integration.
• Squads is working on an integration.

The split matters because Ore offers a completed integration path while four named services remain in development. No launch dates accompany those four projects, so application teams cannot treat their planned support as live distribution.

Chainalysis and Elliptic are supporting compliance through wallet screening. The disclosed compliance arrangement does not change the core disclosure rule: addresses stay visible while asset and amount details remain encrypted.

What does this change for institutions?

Helius is still auditing Custom Rings, a permissioned version for institutions. The company expects it to reach mainnet “in the coming weeks,” with KYC allowlists, sanctions screening, and tools to freeze or recover funds. The launch targets private payments, DeFi, and business applications seeking compliance controls.

For developers, the immediate change is an API for embedding encrypted pools into new or existing Solana apps, with support for SOL, SPL tokens and Token-2022. For institutional operators, the proposition remains incomplete until the permissioned product reaches mainnet and its audit concludes.

The two versions serve different control requirements. Public Privacy Rings conceal asset and amount details while preserving visible addresses and user-controlled viewing keys. Custom Rings adds KYC allowlists, sanctions checks and operational controls over funds.

Institutional teams should therefore separate two claims: privacy tooling is live on Solana mainnet, while the compliance-oriented control layer is still under audit and scheduled for a coming-weeks deployment. Neither available viewing keys nor the planned institutional controls removes the visible-address constraint.

The next concrete checkpoint is Custom Rings’ expected mainnet arrival in the coming weeks, following its audit; until deployment, institutions should treat KYC allowlists, sanctions screening and fund controls as pending rather than operational.
