Helius has brought the permissionless privacy protocol Privacy Rings to the Solana mainnet.

According to PANews, citing an official Solana announcement, developers can use an API to add privacy features to new and existing Solana apps for private payments, private DeFi, and enterprise-compliant privacy. Privacy Rings is a programmable shielded pool where assets and amounts are encrypted and stored on-chain, while wallet addresses remain visible. Users can decrypt balances with a viewing key. It supports SOL, SPL tokens, and Token-2022 tokens, and ZK proof verification takes only a few hundred milliseconds.

· Amounts are encrypted, but addresses remain visible: the pool shields assets and amounts, not the addresses of transaction participants.
· The viewing key has become the control point for balance readability.
