Solana Privacy Rings launch with confidential transfers

Helius has launched Solana Privacy Rings on mainnet, giving users encrypted balances and confidential transfers while keeping wallet addresses visible in its first permissionless ring.

Helius announced the release on Nov. 10, with the Solana Foundation describing the approach as “Public by default, private by choice.” Developers can begin integrating the system through APIs, while the Foundation’s documentation describes Privacy Rings as being in beta.

According to the company’s launch announcement, Decrypt is using confidential transfers for its money account, Ore has added them to its mining and staking app, and Aurora Intents supports moving assets across chains into confidential balances.

Backpack, DFlow, Jupiter, Squads, and Titan are working on integrations, Helius said. Custom Rings remain under audit, with a mainnet release targeted for the fourth quarter of 2026.

Solana Privacy Rings hide amounts while wallets stay visible

Helius’s privacy documentation separates confidential transfers from deposits and withdrawals. Within the default ring, the asset and amount are encrypted, but observers can still see the sender and recipient addresses.

Moving funds into a private balance from a public wallet reveals the source, asset, and amount. A withdrawal exposes the destination, asset, and amount when funds return to a public balance.

Users can decrypt their own balances with a viewing key. In the documentation’s payment example, someone who receives a confidential transfer cannot inspect the sender’s remaining balance or read the amounts of unrelated payments.

Helius offers local and delegated decryption. Keeping the viewing key on the device limits access to the wallet; sharing it with an authorized provider lets that provider read balances and transaction history without granting spending authority.

The company’s product page says users can enter a normal Solana address. Its API sends funds privately when the recipient has a Private Wallet; otherwise, it routes the payment as a withdrawal to the recipient’s public address.

Private transfers execute directly on Solana

According to Helius, Privacy Rings support SOL, SPL tokens, and Token-2022 tokens, with encrypted data stored on Solana’s ledger. The system uses zero-knowledge proofs to verify private transactions.

In its transfer guide, the company explains that a proof demonstrates the sender owns and can spend the selected inputs without revealing the encrypted asset or amount.

“Helius generates proofs and relays your transactions,” the product page states. “We never hold your keys or touch your funds.”

Solana’s documentation describes private escrows that developers can use for swaps, lending, staking, and yield products. Transfers execute natively on the network without a sequencer or sidechain, and movements between rings can settle in one transaction.

Earlier work on Solana privacy included Helius CEO Mert Mumtaz’s public request for protocol names in May, when Ripple CTO emeritus David Schwartz joined the discussion, as crypto.news previously reported.

Custom Rings will add compliance and auditor controls

Helius’s enterprise documentation describes configurable rules for approved participants, blocked recipients, spending freezes, extra signatures, and emergency pauses. A freeze would prevent a listed participant from spending while still allowing incoming transfers.

Auditor access would provide transaction visibility without spending authority. Companies would remain responsible for checking customers, maintaining restrictions, authorizing holds, and handling reporting under the procedures described in the documentation.

Custom Rings are designed to offer either confidentiality, with counterparties visible, or anonymity, which encrypts counterparties and balances.

In the United States, SEC Chairman Paul Atkins discussed comparable technologies in his Dec. 15, 2025, remarks on financial surveillance. He said zero-knowledge proofs and selective disclosure could let users demonstrate compliance without exposing their entire financial history, while specifying that he was expressing his own views.

The product page lists payroll, supplier payments, payment cards, tokenized asset settlement, treasury management, and collateral transfers among potential applications. For wallet developers, Helius offers an integration through its software development kit, while private balances can interact with other Solana programs.

Solana builders are developing other privacy applications

On May 26, Umbra announced confidential vesting with Streamflow, encrypting token allocation amounts, recipient addresses, and unlock schedules through Arcium’s encrypted computation infrastructure.

Solana’s Nov. 9 list of 11 startup requests included privacy among the areas proposed for stablecoin builders, alongside business payment tools, neobanks, and agent payments.

For Privacy Rings, Helius says Certora, ZK Security, and OtterSec have audited the core programs and zero-knowledge circuits. Formal verification remains underway and is expected to finish by the end of 2026.
