Solana Privacy Rings go live: Encrypted transfers on mainnet
4.9 Tech Helius launches Solana Privacy Rings on mainnet, enabling encrypted balances and confidential transfers while keeping wallet addresses visible. Early integrations are live, with more projects joining soon.
Helius has launched Solana Privacy Rings on the Solana mainnet, introducing a permissionless privacy protocol that enables encrypted balances and confidential transfers while keeping wallet addresses visible. This upgrade empowers developers to add privacy features to both new and existing Solana applications via APIs, supporting private payments, DeFi, and enterprise-compliant privacy. Privacy Rings utilize programmable shielded pools, where assets and amounts are encrypted and stored on-chain. Users can decrypt balances using viewing keys. The protocol supports SOL, SPL tokens, and Token-2022 assets, with zero-knowledge proof verification taking only a few hundred milliseconds. Early integrations include Decrypt, Ore, and Aurora Intents, while projects like Backpack, DFlow, Jupiter, Squads, and Titan are working on integration. A permissioned version, Custom Rings, featuring compliance tools such as KYC allowlists and sanctions screening, is under audit and expected to launch in 2026. The Solana Foundation describes the approach as "Public by default, private by choice," aiming to expand privacy without sacrificing speed or liquidity.
