[Helius Launches Privacy Rings Protocol on Solana Mainnet, Supporting Encrypted Asset Types and Amounts for Transfers] According to Foresight News, the Solana Foundation announced that Helius has launched the permissionless privacy protocol, Solana Privacy Rings, on the Solana mainnet. This protocol supports SOL, SPL, and Token-2022 tokens. All asset types and amounts transferred are encrypted, while wallet addresses remain publicly visible. Users can deposit assets into a privacy pool and initiate private transfers to any Solana wallet address, or withdraw assets to their public balance. Transactions are executed and settled directly on the Solana mainnet. Developers can integrate the privacy features into existing applications via API and SDK. Teams such as Jupiter, Backpack, and DFlow are currently integrating the protocol. A 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.
