Helius launches Privacy Rings, putting encrypted balances on Solana

Helius flipped the switch on Solana Privacy Rings on Nov. 10, 2026, bringing encrypted balances to Solana's mainnet. The infrastructure firm calls them programmable shielded pools: shared pools where users deposit tokens, move them privately to other Solana wallets, and pull them back to a normal public balance whenever they want. SOL, SPL and Token-2022 tokens all work inside a Ring, and users never hand over custody — every transfer still needs the owner's signature.

The twist is where the privacy lives. Everything executes directly on Solana and the encrypted data sits on Solana's own ledger, with no separate layer-2 network or sequencer in the middle. That keeps private balances rubbing shoulders with the same stablecoins, tokenized assets and DeFi liquidity as public ones. The Solana Foundation sums up the philosophy as 'public by default, private by choice.'

Helius' developer docs split privacy into two tiers. Confidentiality encrypts the asset and the amount, while anonymity also masks who sent and who received — the default Ring is the confidential kind, like a bank statement with names visible and figures blacked out. Every private transfer carries a Groth16 zk-SNARK, which Helius says can be generated in tens of milliseconds either by a service provider or on the user's own device, and settles in a single Solana transaction. Viewing keys let users decrypt their own balances locally, and a key can be shared for one transaction with an auditor or counterparty without exposing the rest of their history.

Getting in and out is not invisible, at least not always. Moving funds from a public wallet into a Ring, or back out, is visible onchain down to the asset and amount. Users who on-ramp straight from fiat into a private balance through a supported provider keep both hidden from the start, according to Helius.

At launch, Decrypt, mining and staking app ORE and cross-chain service Aurora Intents were already on the default Ring, with Backpack, DFlow, Jupiter, Squads and Titan working on integrations. Helius says Certora, OtterSec and ZK Security audited the core programs and zero-knowledge circuits, and engineers from the Solana Foundation, Blueshift and Zcash joined the trusted setup ceremony that generates the proof parameters. The code is open source on GitHub under Apache 2.0, though formal verification of the circuits is still running and due to wrap by the end of 2026. Solana's own documentation still labels Rings a beta.

Compliance questions arrived with it. The launch landed days after fellow Solana privacy protocol Privacy Cash paused deposits in the wake of the October 2026 Binance hack, saying it wanted to 'make sure bad actors can't use our product' while it tightened wallet screening — stolen funds had already been deposited into its pools, per blockchain analytics firm Elliptic. The default Ring keeps addresses, deposits and withdrawals visible, and Helius works with Range, Chainalysis and Elliptic on screening. Rings is one of three privacy tools Solana documents, alongside Token-2022's Confidential Balances and institution-run Private Channels — and Decrypt has partnered with Helius to offer confidential transfers in the Decrypt Money Account using Rings.
