Helius deployed its Solana Privacy Rings system on the Solana mainnet on November 10, 2026. The protocol lets users and applications conceal token balances and transfer amounts while keeping sender and recipient addresses visible on the public ledger.

Privacy Rings operate as programmable shielded pools that run directly on Solana. Users deposit supported assets into a ring, transfer them to any Solana wallet under encryption, and withdraw funds to a standard public balance when needed. Supported assets include SOL, SPL tokens and Token-2022 tokens. Every transaction still requires the owner’s signature, so users retain custody of their funds throughout.

How Privacy Rings Function

The default ring provides confidentiality rather than full anonymity. It encrypts the specific asset being moved and the quantity transferred. Wallet addresses remain public, similar to a bank statement that shows the parties involved but blacks out the figures. Zero-knowledge proofs, specifically Groth16 zk-SNARKs, confirm that a transfer is valid without revealing the encrypted details. Proof generation takes tens of milliseconds and verification hundreds of milliseconds. Each private transfer settles in a single Solana transaction.

Encrypted balances and data stay on Solana’s mainnet ledger. No separate layer-2 network or external sequencer is required. Users decrypt their own balances locally with a viewing key or allow a service provider to do so. A viewing key for a single transaction can be shared with an auditor or counterparty without exposing an entire history.

Moving funds from a public wallet into a ring, or withdrawing them, is visible on-chain, including the asset and amount. Users who fund a private balance directly from fiat through a supported provider can keep those details hidden from the outset.

Live Integrations and Developer Access

Three integrations were operational at launch. Decrypt’s money account supports confidential transfers. Ore offers the capability through its mining and staking application. Aurora Intents routes assets across chains into confidential balances.

Additional teams including Backpack, DFlow, Jupiter, Squads and Titan are working on integrations. Developers can add Privacy Rings to new or existing Solana applications through an API or software development kit.

Potential applications extend beyond simple transfers. Programs can hold encrypted balances in private escrows and release them under defined conditions. This opens possibilities for private swaps against public liquidity, private lending without publishing positions, private staking and yield on encrypted balances, and conditional payments such as payroll or vesting releases.

Custom Rings for Institutions

Alongside the open default ring, Helius is preparing Custom Rings. These permissioned versions are designed for businesses and institutions and remain under audit. They are expected to reach mainnet in the coming weeks.

Custom Rings can be configured for confidentiality or full anonymity that also hides sender and recipient addresses. Operators can incorporate compliance features including KYC allowlists, sanctions screening, selective disclosure, auditor access, and tools to freeze or recover funds. Because Custom Rings interoperate with the default ring, regulated entities can maintain confidentiality while accessing the same liquidity pools as other users.

Security and Compliance Measures

The core programs and zero-knowledge circuits have been audited by Certora, OtterSec and ZK Security. Formal verification is ongoing and is expected to conclude by the end of 2026. The code is open source under the Apache 2.0 license. Engineers from the Solana Foundation, Blueshift, Zcash and other teams participated in the trusted setup ceremony that generated the proof parameters.

Privacy Rings are currently described as being in beta. The default system leaves addresses, deposits and withdrawals visible. Helius works with blockchain analytics firms including Chainalysis, Elliptic and Range on wallet screening to support compliance needs.

The launch aligns with Solana’s broader approach of remaining public by default while offering private options by choice. Privacy Rings sit alongside other Solana tools such as Confidential Balances and Private Channels, providing a native mainnet path for encrypting financial activity without leaving the network.
