Helius launched Solana Privacy Rings on mainnet on November 10, giving developers a way to add confidential transfers to applications. In the default ring, assets, amounts and optional memos are encrypted, but sender and recipient wallet addresses and the transaction hash remain visible. Deposits from a public balance also reveal the asset, amount and addresses.
Helius says developers can use APIs to build private payments and escrows; swaps, staking and yield-related uses are planned. The Solana Foundation says a separate enterprise version, Custom Rings, is still in audit and expected in the coming weeks. The foundation reports audits of the core programs and proof circuits, while formal verification remains underway.
