Helius launches Privacy Rings, supporting private transfers and programmable privacy features on the Solana chain.

November 10 - According to official sources, Helius has announced the launch of a privacy transaction feature called Privacy Rings, introducing a zero-knowledge proof-based programmable privacy mechanism to the Solana network. This allows users to conduct confidential transfers on-chain while preserving native transaction performance. The feature can hide the asset types and transfer amounts of transactions, but the sender and receiver addresses remain public. All privacy transactions can be settled in a single Solana transaction.

Privacy Rings adopts a non-custodial model, requiring all transfers to be signed by the asset owner, and supports SOL, SPL Tokens, and Token-2022 tokens. Developers can also integrate privacy transfers into Solana programs via API to enable programmable functions such as on-chain private custody. Additionally, the feature supports the creation of custom Privacy Rings, allowing enterprises to configure anonymity levels and compliance rules according to their needs.
