Permissionless privacy protocol launches on Solana mainnet, Helius introduces Privacy Rings

Odaily reports that 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 via API, providing a foundation for private payments, private DeFi, and enterprise-compliant privacy. The protocol uses programmable shielded pools, with assets and amounts stored on-chain in encrypted form while wallet addresses remain visible; users can decrypt balances using viewing keys. The protocol supports SOL, SPL tokens, and Token-2022 tokens, with ZK proof verification taking only hundreds of milliseconds.
