Confidential activity requires integrated applications, and returning to public mode involves an asynchronous withdrawal process. - Balances and transfer amounts can remain confidential, while addresses, transaction timing and some disclosures between modes remain observable. - Fhenix reports a Consensys Diligence audit. Institutions will still need to assess the reviewed components, deployed versions, access permissions and infrastructure trust assumptions. - The company plans three additional applications in Q4 and two institutional partnership announcements. Its confidential stablecoin work with Tandem remains a development plan.
