Helius launches the privacy protocol Privacy Rings on the Solana mainnet

According to official news from Solana, the Solana infrastructure company Helius today launched the permissionless privacy protocol Solana Privacy Rings on the Solana mainnet. Developers can add privacy features to new and existing Solana applications through the API, laying the foundation for private payments, privacy DeFi, and enterprise compliance privacy.

Privacy Rings are programmable shielded pools, with assets and amounts encrypted and stored on-chain, while wallet addresses remain visible. Users can decrypt balances by viewing the viewing key, supporting SOL, SPL tokens, and Token-2022 tokens, with ZK proof verification taking only a few hundred milliseconds. Its core program and ZK circuits have been audited by Certora, OtterSec, and ZK Security. The institution-oriented permissioned Custom Rings are currently under audit and are expected to go live on the mainnet in the coming weeks, supporting compliance features such as KYC whitelisting, sanctions screening, and fund freezing and recovery.

Currently, Decrypt, Ore, and others have integrated, while teams such as Backpack, DFlow, Jupiter, and Squads are in the process of integration, with Chainalysis, Elliptic, and others providing compliance support for wallet screening.
