Helius Launches Privacy Protocol Privacy Rings on Solana Mainnet

November 10: According to Solana's official announcement, Solana infrastructure company Helius today launched the permissionless privacy protocol Solana Privacy Rings on the Solana mainnet. Developers can use an API to add privacy features to new and existing Solana applications, laying the foundation for private payments, private DeFi, and enterprise-compliant privacy. Privacy Rings are programmable shielded pools in which assets and amounts are encrypted and stored on-chain while wallet addresses remain visible; users can decrypt balances with a viewing key. It supports SOL, SPL tokens, and Token-2022 tokens, and ZK proof verification takes only a few hundred milliseconds.

Its core program and ZK circuits have been audited by Certora, OtterSec, and ZK Security. Custom Rings, a permissioned offering for institutions, is currently under audit and is expected to launch on mainnet in the coming weeks, supporting compliance features such as KYC whitelists, sanctions screening, and fund freezing and recovery. Decrypt, Ore, and others have already integrated, while Backpack, DFlow, Jupiter, Squads, and other teams are in the process of integrating; Chainalysis, Elliptic, and others provide compliance support for wallet screening.
