ETHEREUM PRIVACY

Compliant Privacy for Ethereum.

Name: Ethereum Privacy by H33
Brand: H33

Tornado Cash failed because it had no compliance layer. H33 provides one. Every token balance, every DeFi position, every swap is visible on-chain. H33 adds post-quantum privacy with per-transaction compliance attestation.

Tokenize the World — anchored 2026-05-27

A $50M reference treasury transfer’s full institutional state — every encrypted policy gate, every authority transition, every signature — collapsed to one 32-byte SHA3-256 canonical fact, then anchored to Ethereum mainnet. Not compressed. Fully post-quantum attested.
