Business Outcomes for Regulated Platforms

Our privacy-preserving AML & sanctions screening delivers concrete, auditable results for financial institutions and crypto-native businesses. We focus on measurable compliance outcomes, not just technical features.

01

Regulatory Confidence

Deploy with confidence using a solution built on zero-knowledge proofs (ZKPs) and audited by leading security firms. Our architecture ensures your screening process is provably compliant with FATF Travel Rule, OFAC, and EU AMLD6 requirements.

Technical Comparison

ZK Screening vs. Traditional AML Checks

A direct comparison of privacy-preserving ZK-based screening against conventional AML/KYC methods, highlighting key operational and compliance differences.

Comparison FactorTraditional AML/KYCChainscore ZK Screening

Data Privacy & User Experience

Requires full PII exposure (name, DOB, address). High friction for users.

Zero-knowledge proofs verify compliance without exposing user data. Frictionless UX.

Regulatory Compliance

Compliant but relies on data centralization, creating liability.

Compliant while minimizing data liability. Audit trails are cryptographically verifiable.

Integration Complexity

High. Requires deep integration with legacy systems and manual review queues.

Low. API-first design with Web3-native SDKs. Integrate in days, not months.

Operational Cost (Annual)

$100K-$500K+ for licensing, data feeds, and manual review staff.

$50K-$150K. Predictable API pricing scales with volume, reducing manual overhead.

Time to First Screen

Weeks to months for integration and compliance sign-off.

Deploy screening in under 2 weeks with our pre-audited circuits.

False Positive Rate

High (5-15%), leading to costly manual intervention and user drop-off.

Low (<2%). ML-enhanced lists and on-chain context reduce noise.

Coverage

Limited to traditional financial data sources and static lists.

Comprehensive. Combines OFAC, global sanctions, PEPs, and real-time on-chain risk signals.

Auditability

Opaque. Difficult to prove specific checks were performed without exposing all data.

Transparent. Every verification generates a ZK proof for regulators, proving check execution privately.

Scalability

Bottlenecked by manual processes and legacy infrastructure.

Designed for scale. Processes 10,000+ screenings per second with sub-second latency.

PROVEN PROCESS

Our Delivery Methodology

We deliver secure, compliant screening infrastructure through a structured, transparent process designed for technical teams. Each phase includes clear deliverables and direct access to our engineering leads.

01

Architecture & Threat Modeling

We begin with a collaborative design session to map your data flows, define privacy boundaries, and identify regulatory touchpoints. This phase delivers a signed-off technical specification and threat model.

Frequently Asked Questions

Get clear answers on how our zero-knowledge compliance solution integrates, scales, and protects your business.

Our solution uses zero-knowledge proofs (ZKPs) to allow your application to prove a user is not on a sanctions list without revealing their identity or transaction details. We deploy a custom ZK circuit that takes a user's address as a private input, checks it against an on-chain registry of hashed sanctions data, and outputs a public proof of compliance. The sensitive data never leaves the user's device, and the proof is verified on-chain in under 500ms.
