Foresight News reports that according to the Solana Foundation announcement, Helius has launched the permissionless privacy protocol Solana Privacy Rings on the Solana mainnet. This protocol supports SOL, SPL, and Token-2022 tokens, with both the asset types and amounts encrypted, while wallet addresses remain publicly visible. Users can deposit assets into privacy pools, initiate private transfers to any Solana wallet address, or withdraw assets back to public balances. Transactions are executed and settled directly 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 this protocol. The permissioned version for institutions, Custom Rings, is currently under audit and is expected to launch on the mainnet in the coming weeks, supporting selective disclosure, audit access, and KYC-based whitelisting.
