Shield
Shield is human.tech’s bridge to Aztec — a privacy-preserving bridge between Ethereum L1 and Aztec L2, and the first app built on the Clean SDK, human.tech’s programmable privacy toolkit for Aztec. Move tokens into Aztec’s private layer while proving a real, unique human with clean funds is behind the transfer, without revealing personal information.
Audited by Nethermind Security (May 2026). The privacy-preserving, accountable bridge to Aztec — identity, sanctions, and PEP screening at every deposit and exit. Screening is enforced cryptographically: zero-knowledge proofs at identity issuance, on-chain attestation verification at every deposit.
Every transaction clears Proof of Innocence (wallet + funds vs 23 sanctions sources) and proves a real, unique human via Proof of Personhood — Human Passport or Proof of Clean Hands.
Live on Aztec Mainnet Alpha (v4.3). Real ZK proofs since 2026-05-29. Aztec is currently in Alpha: 1 TPS, ~6s block times, ongoing audits + bug bounty. Public launch aligned with Aztec v5.
