Helius launches Solana privacy protocol

Highlights

Helius launches Solana Privacy Rings on mainnet, enabling permissionless encrypted asset transfers and balances for SOL, SPL, and Token-2022 tokens.
The protocol uses zero-knowledge proofs to ensure private DeFi transactions execute with sub-second finality, with audits by Certora, OtterSec, and ZK Security and formal verification ongoing through 2026.
Helius plans to release Custom Rings for institutional permissioned privacy with KYC and compliance features, with mainnet launch expected within weeks following audits.

Mainnet launch and product scope

As reported by Solana, citing Solana News, Helius today launches Solana Privacy Rings on mainnet as a permissionless privacy protocol built directly on Solana. The product is designed to let developers add privacy features to new and existing applications through APIs, with the aim of supporting private payments, private DeFi and compliance-focused business use cases.

The protocol uses programmable shielded pools with encrypted onchain balances and native Solana execution. Helius says assets and amounts are encrypted while wallet addresses remain visible, and users can decrypt balances with a viewing key, deposit assets into a private balance, send confidential transfers to any Solana wallet and withdraw back to a public balance.

Helius says the system supports SOL, SPL tokens and Token-2022 tokens, while private transactions execute on Solana and encrypted state is stored on the network ledger. The company adds that succinct zero-knowledge proofs verify transactions in a few hundred milliseconds, preserving Solana's sub-second finality, and that audits have been carried out by Certora, OtterSec and ZK Security, with formal verification underway and expected to finish by the end of 2026.

In a statement included in the announcement, Helius CEO Mert Mumtaz says privacy is the final scaling frontier in crypto and argues that institutions and individuals will not be comfortable exposing their financial identity permanently on a public ledger. Cat McGee, technical privacy lead at Solana Foundation, says privacy needs to become part of the sector's infrastructure as more real money moves onchain.

DeFi integrations and institutional roadmap

Beyond private transfers, the protocol is positioned as infrastructure for broader financial applications on Solana. Helius says Solana programs can use encrypted balances in private escrows and combine private transactions with other Solana programs in a single transaction, allowing traders, lenders and treasury users to keep positions confidential while still accessing public liquidity.

The company lists potential applications including private swaps, private lending, private staking and yield products, and conditional payments for payroll, vesting, multisig treasuries and delivery-versus-payment settlements. Helius says this model keeps privacy as an asset-level setting rather than requiring a separate network with fragmented liquidity.

Helius also outlines a next product release, Custom Rings, aimed at institutions that want permissioned private environments directly on Solana mainnet. The company says those deployments are expected to offer features such as confidential or anonymous counterparties, auditor visibility, selective disclosure, KYC-gated allowlists, sanctions screening, and the ability to freeze and recover funds, with mainnet availability expected in the coming weeks after audits.

The permissionless Ring is already live with products launching on it, according to Helius. The company says Decrypt, Ore and Aurora Intents already support confidential transfers or balances, while firms including Range, Chainalysis, Elliptic, Crossmint, MoonPay, Paybis, Backpack, DFlow, Jupiter, Squads and Titan are supporting compliance, payments or DeFi integrations around the privacy protocol.

As we noted earlier, Lenovo’s upcoming CES 2027 keynote will spotlight Hybrid AI technologies with an emphasis on privacy, security and data control.
