Helius launched Solana Privacy Rings on mainnet on November 10, according to an announcement published by the Solana Foundation. The protocol adds shielded pools in which asset balances and transfer amounts are encrypted onchain, while settlement stays on Solana rather than on a separate layer-2 network.
Users deposit tokens into a private balance, send private transfers to any Solana address and withdraw to a public balance. Only the owner can decrypt a balance with a viewing key, and every transaction requires the owner’s signature. Rings support SOL, SPL tokens and Token-2022 tokens. Decrypt reported that sender and recipient addresses remain visible in the default Ring, and that moving funds in or out of a Ring from a public wallet reveals the asset and amount.
The announcement said zero-knowledge proofs verify in a few hundred milliseconds. It named Certora, OtterSec and ZK Security as auditors of the core programs and circuits. Formal verification is still under way and expected to finish by the end of 2026, and Decrypt reported that Solana’s documentation describes Rings as being in beta.
Helius also announced Custom Rings, permissioned versions with KYC allowlists, sanctions screening, auditor visibility and freeze-and-recovery functions. They remain in audit, with mainnet expected in the coming weeks. Early integrations include the mining app Ore and the cross-chain tool Aurora Intents, the announcement said. Because the announcement is a company-backed release, its performance and security claims are self-reported.
