Exosphere — Confidentiality Layer for Stablecoins

Blurb — Exosphere is the confidentiality layer for stablecoins. Issuers use Exosphere’s plug‑n‑play solution to unlock access to enterprise and institutional users by enabling an FHE‑encrypted mode for any existing stablecoin.

What we do​

  • One‑click “Confidential Mode”: wrap any ERC‑20 stablecoin 1:1 at par into a fhERC‑20 confidential variant ($exoTOKEN), with encrypted balances and transfer amounts and full ERC‑20 composability.
  • Issuer‑first controls: preserve base‑token controls (freeze/pause, mint/burn roles, allowlists, transfer limits).
  • Selective transparency: grant view keys to scoped compliance roles; every grant is logged and revocable.
  • Chain‑agnostic EVM: deploy wherever your stablecoin lives; no dependency on a special L2.
  • Liquidity out‑of‑the‑box: confidential yield to drive utility from day one.

Who it’s for​

  • Stablecoin issuers that want to expand distribution to high-value enterprise/institutional users without redesigning their token or launching a separate token.
  • Neobanks, fintech platforms, and other companies launching branded stablecoins, aiming to serve enterprise and institutional users.

How it works at a glance​

  1. Users or partners toggle Confidential Mode (wrap/unwrap) between the transparent rail and the confidential rail.
  2. The confidential token keeps amounts and balances encrypted using the fhERC‑20 standard (FHE).
  3. Compliance uses view‑keys for selective audits; public supply↔reserve invariants remain verifiable.
  4. Redemptions support three modes, from public unwrapping to shielded off‑ramp and programmatic netting.
