TL;DR
Helius launched Solana Privacy Rings on mainnet, offering permissionless encrypted balances and private transfers while keeping execution, settlement and liquidity directly on Solana.
The protocol supports SOL, SPL and Token-2022 assets, with ZK proofs verifying private transactions in a few hundred milliseconds without changing sub-second finality.
Custom Rings will add permissioned privacy for businesses, including audit access, selective disclosure, KYC allowlists, sanctions screening and fund recovery controls for regulated institutions.
Helius launched Solana Privacy Rings on mainnet, introducing a permissionless privacy protocol that executes and settles directly on Solana. According to the official Solana announcement , developers can add privacy through APIs while keeping activity on the same network. Privacy Rings encrypt assets and amounts while wallet addresses remain visible, letting users control private balances with viewing keys. The launch expands privacy capabilities on Solana without moving users away from existing liquidity or sub-second settlement.
Privacy Rings Keep Execution and Liquidity on Solana
Users can deposit assets into private balances, transfer privately to any Solana wallet and withdraw to public balances. Rings support SOL, SPL tokens and Token-2022 assets, while every transaction requires the owner’s signature. Private transactions execute natively on Solana, with encrypted state stored onchain and zero-knowledge proofs verified within a few hundred milliseconds. Helius says the core programs and ZK circuits were audited by Certora, OtterSec and ZK Security, with formal verification expected by the end of 2026.
The system extends beyond confidential transfers. Solana programs can hold encrypted balances in private escrows and release funds when conditions are met, while private transactions can compose with other programs in one transaction. That programmability enables private swaps, lending, staking, yield strategies and conditional payments while users continue accessing public liquidity. Potential uses include payroll, vesting, multisig treasuries and private deal terms settled through Solana DvP , supporting programmable privacy for financial applications.
Helius is also preparing Custom Rings for businesses and institutions. These permissioned environments will run on Solana mainnet and let operators decide what remains hidden, while supporting auditor visibility, selective disclosure, KYC-gated allowlists, sanctions screening and mechanisms to freeze or recover funds. Custom Rings are intended to combine market confidentiality with regulatory visibility without isolating participants from shared liquidity. They remain under audit and are expected on mainnet in the coming weeks, extending Solana’s institutional privacy framework .
The permissionless Ring is already live, with Decrypt, Ore and Aurora Intents among products using confidential balances and transfers. Range, Chainalysis and Elliptic already support compliance flows. Helius built SDKs and APIs so developers can add privacy without requiring deep zero-knowledge expertise. Tooling includes TypeScript and Rust SDKs, dedicated privacy RPC methods, remote or local proof generation and Blueshift’s XARK toolchain for custom ZK circuits, broadening privacy tooling on Solana .
