Helius activated Solana Privacy Rings on Solana’s mainnet on November 10, 2026, introducing shielded pools that encrypt balances and transfer amounts. Sender and recipient addresses remain visible, while zero-knowledge proofs allow the network to validate transactions, prevent double-spending and confirm that tokens were not created without corresponding assets. The solution supports SOL, standard SPL tokens and Token-2022 tokens from launch, operates on a self-custodial model and gives developers access through simple APIs. The core programs and zero-knowledge circuits were audited by Certora, OtterSec and ZK Security, while formal verification is expected by the end of 2026. Helius is also developing configurable enterprise versions targeted for the fourth quarter of 2026, subject to the completion of audits and formal verification.
