Nox is a trustless, multichain confidential execution protocol for DeFi — with programmable auditability.
Nox Protocol builds the first truly on-chain composable privacy layer for DeFi, multichain, multi-privacy. Gas-efficient confidential computation at blockchain speed: like HTTPS made secure connections invisible, Nox makes privacy the default. Seamless for users, effortless for builders who can develop and monetize their own confidential functions, auditable for regulators.
- Smart contracts manipulate handles instead of plaintext values — ciphertexts never appear in the clear on-chain
- Confidential computations run inside Runners (attested TEEs), ensuring data remains encrypted even during processing
- A distributed KMS powered by threshold ECIES and Shamir secret sharing splits decryption keys across multiple nodes — no single party can decrypt data alone
- Decryption is delegated to the client: each KMS node computes a partial re-encryption share, reassembled client-side, so the KMS never sees plaintext
- On-chain ACLs make permissions explicit, auditable, and revocable — enabling programmable auditability and selective disclosure
- Yield with Confidential Vault
- cRWA with confidential Tokenized Equity on-chain
- Confidential value transfers
- Privacy-preserving DeFi primitives
- Tokens with hidden balances & amounts
- Selective disclosure workflows (audit, compliance)
- Institutional-grade DeFi & RWAs
The Confidential Token is the first Nox-based product: an ERC-7984 (OpenZeppelin)-compliant confidential ERC-20. It showcases the Nox protocol in action — no need to understand the full stack to get started.
With the Confidential Token, you can:
- Create a native confidential token (cToken)
- Shield / Unshield — wrap an existing ERC-20 into a cToken and unwrap it back
- Swap cTokens (ERC-7984 to ERC-7984) with fully encrypted amounts
- Transfer with hidden balances and amounts
- Grant viewing permissions via on-chain ACL for selective disclosure
