Product — Toggle Confidential Mode

One‑click toggle from the public rail to a confidential fhERC‑20 variant.

Our product offering​

  • White‑label confidential wrapper for ERC‑20 stablecoins (fhERC‑20).
  • Policy & view‑key tooling for compliance (enable only when required).
  • UI for managing confidential assets and accessing confidential strategies (with plans to build expanded app ecosystem). See exoSave (V1).

“Confidential Mode” for issuers​

A. Confidential variant of your stablecoin ($exoTOKEN)​

  • Mechanics: $TOKEN ↔ $exoTOKEN 1:1 via secure wrapper vaults; base‑token controls and redemption remain unchanged.
  • Economics: Confidential accrual can mirror the base token’s yield/crediting semantics via encrypted accounting.
  • Compliance: Allow‑lists, policy hooks, and selective disclosure via view‑keys; administered by the issuer (Exosphere has no unilateral authority).

B. Confidential wrappers for all issuer‑minted stablecoins​

  • Retrofit existing tokens and enable for new mints (opt‑in).
  • One standardized confidential rail → uniform UX and unified liquidity.

Mint/Redeem & On/Off‑Ramps (overview)​

  • Mode A — Public Unwrap: Burn confidential, release base token (visible amounts).
  • Mode B — Shielded Off‑Ramp Redemption: Allowlisted off‑ramp burns confidentially and pays fiat off‑chain; wrapper nets reserves periodically.
  • Mode C — Programmatic Netting: Aggregate confidential burns/mints; settle periodically to reduce linkability.
