F.A.Q

What are confidential tokens?

Confidential tokens bring a new layer of privacy to digital assets by encrypting balances, transfers, and smart contract interactions — all onchain. This immediately unlocks onchain finance for companies, institutions, and individuals who need to keep sensitive details private. It also creates a new design space for DeFi, bringing confidentiality to yield generation, staking, trading, money markets, and more.

Is exoUSD an ERC-20? How does it work?

exoUSD is built on the fhERC-20 standard, which extends ERC-20 by incorporating Fully Homomorphic Encryption (FHE) for confidential, encrypted token balances and transactions. It maintains compatibility with ERC-20 interfaces and FHE libraries, enabling privacy preserving fungible tokens. The fhERC-20 standard is developed by Fhenix.
