Helius has announced the release of Solana Privacy Rings, bringing programmable privacy to payments, DeFi and upcoming institutional applications, on mainnet. The system maintains balances and transfer amounts as encrypted zero knowledge proofs, which are yet to be performed natively on Solana.

Privacy Rings are shielded pools, directly implemented on Solana, that are programmable. The default permissionless Ring encrypts the amount and assets being transferred, but public displays of wallet addresses. They can decipher their own balance with a viewing key.

It is compatible with SOL, SPL and Token-2022 assets. Private transactions take place right on Solana, while private data stays on the Solana network ledger for the benefit of the user.

Helius claims the zero-knowledge proofs can verify private transactions in just milliseconds, which means that users can now transfer funds without having to wait for a separate sidechain or external privacy network.

Developers can even implement more elaborate applications using private escrows. The initial use cases include private swaps, lending, staking, yield products and conditional payments, Helius said. With a single transaction, private balances can communicate with other programs on Solana and be liquidity providers to each other.

Helius says that the system is already being used by Decrypt, Ore and Aurora Intents. Other teams on integrations are BackPack, DFlow, Jupiter, Squads and Titan.

Helius is also working on Custom Rings for financial institutions requiring privacy without compromising compliance regulations.

Participants can be visible or invisible, and institutions will be able to specify their approved participants, block addresses and block activity or require added signatures.

Auditor keys may be provided to audit to be able to view balances and transactions but not control funds. Some transactions can also be selectively disclosed using dedicated viewing keys.

Custom Rings are currently being audited, and its launch on the Solana Mainnet is planned for Q4 2026.

Helius APIs and software development kits enable developers to start integrating Privacy Rings.

Its tooling consists of TypeScript and Rust SDKs, Blueshift privacy-aware RPC methods and zero-knowledge development tools. Helius is also in the process of developing an on-chain wallet which will allow for public and private balances.

The core programs and zero-knowledge circuits have already undergone audits by Certora, ZK Security and OtterSec, and the formal verification process will persist until the end of 2026.
