FHE (Fully Homomorphic Encryption) — Cryptography enabling computation on encrypted data.

fhERC‑20 — An ERC‑20‑compatible standard that stores encrypted balances and encrypted transfer amounts on‑chain while keeping ERC‑20 semantics.

Confidential Mode — The 1:1 wrapped confidential variant of an issuer’s ERC‑20 stablecoin.

View Key — A scoped decryption key that grants read‑only visibility to amounts/balances for authorized compliance roles.

Wrapper Vault — The contract that escrows base tokens and mints/burns the confidential variant at par.

Programmatic Netting — Periodic batch settlement between the wrapper and issuer reserves that reduces linkability of individual flows.

exoSave — A vault that accepts confidential tokens ($exoTOKEN) and routes underlying base assets to allow‑listed, low‑risk DeFi protocols to earn yield. Amounts remain encrypted; compliance visibility is selective via view‑keys.
