Web3Firewall for Stablecoin & Token Issuers

Continuous, Privacy-Preserving Proof of Solvency Across Chains

Who it’s for: Issuers operating across multiple blockchains with obligations for continuous reserve validation, circulation monitoring, issuance caps, and jurisdiction-specific solvency rules.

What you get: Verifiable solvency proofs (“Assets ≥ Liabilities”), reserve-ratio attestations, and automated encrypted alerts—produced without exposing wallet structures or reserve composition.Optional on-chain publication for auditors, partners, or ecosystem tooling.

What this includes: Configurable, continuous solvency proofs (sub-minute to event-driven) covering on-chain, off-chain, and contingent liabilities via encrypted data feeds. Integration is simple through secure APIs with optional on-chain anchoring. Proofs can remain private or be publicly published. Automated alerts, thresholds, and policy workflows are powered by Web3Firewall’s SIEM/SOAR engine.

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.
