Helius has rolled out a protocol update, launching permissionless Solana Privacy Rings on the Solana mainnet, as reported in on-chain news. The privacy protocol enables developers to integrate privacy features via APIs, supporting private payments, DeFi, and enterprise compliance. Assets and amounts are encrypted on-chain within programmable shielded pools, while wallet addresses remain visible. Supported assets include SOL, SPL tokens, and Token-2022 tokens, with ZK proofs verified in under a second. The core code and ZK circuits have been audited by Certora, OtterSec, and ZK Security. Institutional custom Rings are currently under audit, featuring capabilities such as KYC whitelisting and fund recovery. Decrypt and Ore have already integrated, with Backpack, DFlow, Jupiter, and Squads set to follow. Chainalysis and Elliptic provide compliance tools for wallet screening.
