Helius has launched Solana Privacy Rings, a permissionless privacy protocol, on the Solana mainnet. This protocol supports SOL, SPL, and Token-2022 tokens, with encrypted asset types and amounts for transfers, while wallet addresses are publicly visible. Users can deposit assets into a privacy pool, initiate private transfers to any Solana wallet address, or withdraw assets to their public balance. Transactions are executed and settled on the Solana mainnet.
Developers can integrate privacy features into existing applications via API and SDK. Teams such as Jupiter, Backpack, and DFlow are currently integrating the protocol. The licensing-based institutional version, Custom Rings, is currently under audit and is expected to launch on the mainnet in the coming weeks. It will support selective disclosure, audited access, and KYC-based whitelisting. (Source: Solana Foundation)
