Polygon privacy is the expression of the H33 Privacy Layer on Polygon — it lets you anchor a portable, post-quantum H33-74 evidence commitment on Polygon while the underlying data stays private, proven with zero-knowledge (ZK) and selective disclosure. It exists because a public chain gives you ordering and availability but not privacy or portable post-quantum proof; Polygon is the reference environment the evidence anchors to, never the owner of that evidence.

Solana-Privacy proved compliance to the regulator and privacy to the user on Solana devnet today. Polygon-Privacy brings the same H33-74 attestation to EVM-native rails — DeFi, RWA, and traditional-finance settlement.
Schedule Demo See Solana-Privacy (Live)The same 74-byte H33-74 bundle that ships on Bitcoin and Solana — signed with the three-family PQ stack (ML-DSA-65 + FALCON-512 + SLH-DSA-128f), pinned to Polygon zkEVM mainnet as 32-byte calldata, and re-verifiable locally via a 47 KB WASM module. The Polygon zkEVM mainnet stream above is live now; the one-click anchor submission below is being rate-limited before public release.
Anchor submission currently requires an authenticated H33 API key. Public one-click anchoring is being rate-limited before release. Email support@h33.ai for an API key, or watch the mainnet block stream below until the public anchor route ships.
Tornado Cash proved privacy without compliance becomes a regulatory dead end.
Polygon-Privacy proves privacy to the user while proving compliance to the regulator — post-quantum signed, replayable offline, and portable across Bitcoin, Solana, and Polygon zkEVM.
That’s the operational primitive institutional AI and RWA systems are missing.
Every H33-74 receipt is reconstructible from its commitment. Inspect lineage. Inspect proof. Inspect DAG. Verify signatures.
Wallet balances, ERC-20 holdings, DeFi positions, RWA ownership, bridge flows, counterparties, and contract interactions stay hidden, while cryptographic validity, compliance, and balance sufficiency remain provable. It is bounded confidentiality of evidence, not anonymity.
The reference environment: the commitment anchors to Polygon zkEVM (chain ID 1101 / cardona 2442) as calldata, an EVM-native, Ethereum-secured rollup. The primitive itself is unchanged from every other chain.
The 74-byte post-quantum attestation, three-family PQ signature bundle, replay reference, and cross-chain portability are all supplied by H33-74. Polygon supplies none of it.
A combination of zero-knowledge (STARK) proof, data minimization (32 bytes on-chain), and selective disclosure. It does not use FHE — for encrypted compute see /fhe/. Note: Polygon zkEVM's own zk-rollup proofs secure the chain; they are separate from H33's attestation proofs.
Polygon zkEVM's rollup proofs secure state transitions but provide no account privacy, no selective-disclosure compliance proof, no post-quantum attestation, and no portable independently-verifiable evidence. Native account state is public.
Through H33 Verification — replay the STARK proof, re-check the three PQ signatures, and confirm the calldata commitment with the open-source verifier (locally re-verifiable via the WASM module). No trust in H33 or Polygon is required.
Prefer another chain page when the activity is not on Polygon zkEVM, and prefer FHE when the requirement is computing over data that must stay encrypted rather than proving facts about it.
Compliance to the regulator. Privacy to the user. Post-quantum attestation that survives the day a quantum computer cracks ECDSA.
