DEFI PRIVACY

Verify Financial Properties Without Seeing the Numbers.

DeFi protocols need to know if a user qualifies -- not what they own. H33 proves balance ranges, collateral ratios, and portfolio thresholds without revealing the underlying values. Post-quantum attested. 32 bytes on-chain.

THE PROBLEM
Every balance check is a broadcast.

Every on-chain balance check exposes the user to MEV bots, front-runners, and surveillance. A lending protocol that checks collateral reveals the borrower's exact position size. A DEX that verifies trading tier reveals the trader's full portfolio. An insurance contract that checks coverage ratio reveals every holding.

The protocol only needs a boolean -- true or false. Today it gets everything.

THREE ENDPOINTS
One API call. One boolean. Zero exposure.
Each endpoint accepts encrypted financial data, evaluates a property, and returns a post-quantum attested proof that the property holds -- without revealing the data itself.
POST
/api/v1/privacy/defi/balance-range
Balance in range, exact amount hidden.
  • Lending: prove borrower has sufficient reserves without revealing total holdings
  • DEX tiers: prove trader qualifies for institutional tier without exposing portfolio size
curl -- balance-range
curl -X POST https://privacy.h33.ai/api/v1/privacy/defi/balance-range \ -H "Content-Type: application/json" \ -d '{ "balance_encrypted": true, "min_balance": 100000, "max_balance": 10000000, "denomination": "USDC" }'
POST
/api/v1/privacy/defi/collateral
Ratio meets minimum, values hidden.
  • Prove collateral-to-debt ratio >= 150% without revealing either value
  • Liquidation protection without exposing position size or entry price
curl -- collateral
curl -X POST https://privacy.h33.ai/api/v1/privacy/defi/collateral \ -H "Content-Type: application/json" \ -d '{ "collateral_encrypted": true, "debt_encrypted": true, "min_ratio_percent": 150 }'
POST
/api/v1/privacy/defi/portfolio-threshold
Portfolio qualifies, holdings hidden.
  • RWA platforms: prove portfolio meets accreditation tier without revealing positions
  • Insurance: prove coverage ratio without revealing individual holdings or allocations
curl -- portfolio-threshold
curl -X POST https://privacy.h33.ai/api/v1/privacy/defi/portfolio-threshold \ -H "Content-Type: application/json" \ -d '{ "portfolio_encrypted": true, "min_total_value": 1000000, "accreditation_tier": "qualified_purchaser" }'
EXPOSURE MODEL
What the protocol sees vs. never sees

Protocol Sees

  • ✓ claim_satisfied: true
  • ✓ 32-byte commitment hash
  • ✓ Attestation type (0x63)
  • ✓ PQ signature bundle
  • ✓ Proof timestamp
  • ✓ Solana program ID
  • ✓ Verification status

Protocol Never Sees

  • × Exact balance amount
  • × Collateral value
  • × Debt value
  • × Portfolio composition
  • × Individual holdings
  • × Position sizes
  • × Wallet address correlation

This is the actual response format returned by the DeFi privacy endpoints. The protocol gets a boolean and a commitment. Nothing else.

The protocol knows the balance is in range. It never learns the amount.

USE CASES
Every DeFi primitive that checks a number
Lending

Collateral Verification

Prove a borrower meets the 150% collateral ratio without revealing position size, entry price, or total collateral value. The liquidation engine gets a boolean, not a balance sheet.

DEX Access

Institutional Tier Qualification

Prove a trader qualifies for institutional-tier fee schedules, deeper liquidity, or block trade access without revealing their portfolio to the exchange or other participants.

Insurance

Coverage Ratio Proof

Insurance protocols can verify that a user's coverage ratio meets requirements for a payout without seeing the underlying portfolio composition or individual position sizes.

RWA Platforms

Accreditation Verification

Real-world asset platforms can verify a user meets qualified purchaser or accredited investor thresholds without the user revealing their complete financial picture.

ARCHITECTURE
Same architecture. No new mental model.

Same 32-byte commitment. Same three-family PQ signing. Same ShieldProofResponse.

DeFi Privacy uses the identical attestation pipeline as every other H33 privacy product. If you have integrated one H33 endpoint, you have integrated all of them. The proof format is the same. The verification path is the same. The Solana program is the same.

Three endpoints. One boolean each. Zero plaintext exposure. Post-quantum attested.
