Web3Firewall for Stablecoin and Token Providers

Privacy-preserving Proof of Solvency with ZK + FHE option

Who it’s for: Fiat-backed and crypto-collateralized stablecoin or token issuers navigating state, national, and regional solvency requirements — including issuance caps, reserve validation, and continuous monitoring obligations.

What you get: verifiable “Assets ≥ Liabilities” proofs, collateral-ratio attestations (e.g., 99% / 110% / 200%), and automated alerts delivered privately via Zero-Knowledge Proofs (ZK) and Fully Homomorphic Encryption (FHE), with optional on-chain publication for third-party verification

Why Issuers Can’t Rely on Quarterly PDFs Anymore

Regulators demand continuous solvency assurance.

Traditional attestations leak sensitive data.

Over-collateralisation locks up capital.

The Web3Firewall Answer

Reserve Guardian is our privacy-preserving Proof of Solvency platform for issuers.

Continuous, verifiable solvency

Compute “Assets ≥ Liabilities” at frequent intervals; publish a succinct proof for partners/regulators when needed.
‍

Collateral-ratio attestations without disclosure

Publicly state “≥99%”, “≥110%”, or “≥200%” matched collateral while keeping reserve composition confidential.

End-to-end encryption with FHE

Aggregate and analyse reserve balances without decrypting them; only proofs are shared.

ZK integrity & optional on-chain posting

Generate ZKPs that auditors and partners can verify; anchor to chain via ReserveGuardianOracle.

Capital efficiency

Proofs support risk-based margining so you avoid unnecessary over-collateralisation.

Primary value

Regulatory-grade assurance, data-private by design, with optional public verifiability.
