Institutional Privacy

Privacy Infrastructure for Institutions.

Name: H33 Institutional Privacy
Brand: H33

Banks, custodians, and regulated entities need privacy they can prove compliance for.

Institutional digital asset participation requires two things that existing infrastructure cannot provide simultaneously: competitive privacy and regulatory compliance. H33 delivers both.

One API call. 32 bytes on-chain. No PII custody. Post-quantum survivable.

The Problem

The institutional privacy gap.

Institutions cannot participate in DeFi or hold digital assets publicly without revealing competitive information. Trading strategies, portfolio allocations, counterparty relationships, order flow -- all visible on public ledgers. But they also cannot use existing privacy tools. Tornado Cash is sanctioned. Mixers are non-compliant. Privacy chains lack regulatory frameworks. The gap between what institutions need and what exists today is the institutional privacy gap.

Public Ledgers

Competitive intelligence leakage

Competitors monitor your wallets. Counterparties front-run your trades. Portfolio positions become public intelligence. Institutional participation means institutional exposure.

Existing Privacy Tools

Regulatory non-compliance

Tornado Cash: sanctioned. Mixers: flagged by compliance tools. Privacy chains: no regulatory framework. No existing privacy tool satisfies institutional compliance requirements.

H33 Institutional Privacy

Privacy for competitive protection. Compliance for regulatory requirements.

STARK proofs verify that regulatory requirements are satisfied without revealing the underlying positions, trades, or counterparties. The institution maintains competitive privacy. The regulator maintains compliance visibility. Neither compromises for the other.

Use Cases

Privacy and compliance by institution type.

Each institution type has specific privacy requirements and specific compliance obligations. H33 addresses both simultaneously for each.

Banks

Wire Privacy + AML Proof

Process wire transfers and cross-border payments privately while producing per-transaction AML compliance attestations.

Transaction routing without counterparty exposure
Per-transaction AML screening attestation
Correspondent banking privacy
BSA/CTR threshold monitoring without amount disclosure
Examiner-verifiable compliance evidence

Asset Managers

Portfolio Privacy + Fiduciary Proof

Protect portfolio positions and strategy while proving fiduciary compliance and investment mandate adherence.

Position privacy across public chains
Investment mandate compliance proof
Concentration limit attestation without positions
Best execution proof without order details
LP reporting without position disclosure

Insurance

Claims Privacy + Actuarial Proof

Process claims and manage reserves privately while proving actuarial soundness and regulatory capital adequacy.

Claims processing without PII exposure
Reserve adequacy attestation
Actuarial model validation without model disclosure
Reinsurance verification without cedent exposure
Regulatory capital proof

Exchanges

Order Flow Privacy + Market Surveillance Proof

Protect order flow and trading activity while proving market surveillance and manipulation monitoring compliance.

Order flow privacy from external observers
Market manipulation monitoring attestation
Wash trading detection proof
Volume and liquidity attestation
Regulatory audit trail without trade details

Integration

One API call. 32 bytes on-chain. No PII custody.

Integration is a single REST endpoint. The institution submits a compliance claim. H33 generates the STARK proof, signs with three PQ families, and returns a 32-byte commitment ready for on-chain anchoring. No PII crosses the wire. No data custody required.

                
                institutional integration
            
// One API call from your compliance system
const attestation = await h33.attest({
  claim:    "aml_screening_passed",
  entity:   "institution_id_hash",
  chain:    "solana",     // or bitcoin, ethereum, base, arbitrum
  epoch:    "24h",        // OFAC cadence
});

// Returns:
// attestation.commitment  → 32 bytes (on-chain anchor)
// attestation.cachee_key  → retrieval key for full proof
// attestation.expires_at  → epoch expiry timestamp
// attestation.revocable   → true

// What was NOT sent to H33:
// - transaction details
// - counterparty identities
// - portfolio positions
// - client PII

Lifecycle

Create. Verify. Refresh. Revoke.

Attestations are living compliance objects. They are created when compliance is verified, queried when counterparties need proof, refreshed when epochs expire, and revoked when circumstances change. Every state transition is immutably recorded.

Step 1

Create

STARK proof generated from compliance claim. H33-74 attests with three PQ families. 32-byte commitment anchored on-chain. Full proof stored in Cachee.

Step 2

Verify

Any party verifies independently. On-chain commitment check, H33-74 signature verification, or full STARK proof verification via the public HATS verifier.

Step 3

Refresh

When attestation approaches epoch expiry, institution re-attests. New proof generated, new commitment anchored. Previous attestation remains in the audit trail.

Step 4

Revoke

Circumstances change. Attestation revoked immediately. On-chain status updated. All verifiers see revocation in real time. Compliance state changes take effect instantly.

Attestations are time-bound, revocable, and portable. Compliance is continuous, not static. Evidence is exportable for audits, litigation, and regulatory examinations.

Post-Quantum Survivability

Institutional evidence must hold for 30+ years.

Banks store records for decades. Insurance claims span generations. Regulatory evidence must be verifiable years after the fact. Classical cryptographic signatures will not survive the quantum transition. Every compliance attestation signed with ECDSA or RSA today will be unverifiable when quantum computers arrive. Institutional privacy infrastructure must be post-quantum from day one.

Three Hardness Assumptions

H33-74 attests with three independent mathematical hardness assumptions: MLWE lattices (ML-DSA), NTRU lattices (FALCON), and stateless hash functions (SLH-DSA). Breaks only if all three are simultaneously broken.

NIST FIPS Standards

All three PQ families are NIST-standardized (FIPS 203, 204, 205). Not experimental. Not academic. Production-grade post-quantum cryptography deployed at institutional scale.

Hash-Based STARK Proofs

STARK proofs are hash-based and post-quantum secure by construction. No elliptic curve assumptions. No pairing-based cryptography. Only collision-resistant hash functions under SHA3-256.

Harvest-Now-Decrypt-Later

Adversaries are capturing encrypted institutional data today, waiting for quantum computers to decrypt it later. Compliance evidence signed with classical cryptography is already being harvested. The migration deadline is not when quantum computers arrive -- it was years ago.

Built for the institutions that cannot afford to get privacy wrong.

Privacy for competitive protection. Compliance for regulatory requirements. Post-quantum survivability for evidence that must hold for decades.
