Use Cases

Six ways exchanges use
the VIZI® Score

Every use case plugs directly into existing exchange product surfaces. No new logic required — the 300–850 scale translates immediately into your existing risk tiers.

🔥

Leverage tier gating

Grant higher leverage to users with VIZI® scores above your threshold. A 700+ score signals responsible collateral management and clean repayment history — factors directly predictive of margin behavior.

Retention & product

Consolidated AML screening

Every score pull includes real-time OFAC, OFSI, Chainalysis, and Chainabuse screening. Route deposits, withdrawals, and high-value trades through a single credit-and-compliance call instead of managing separate AML vendor contracts.

Compliance
💰

Lender referral revenue

When your users apply for credit at a VIZI®-integrated lender, you earn a referral commission on every funded loan. High-score user bases convert at much higher rates — and at larger loan sizes.

New revenue
🏋

Reduced withdrawal friction for trusted users

Apply lower friction thresholds — reduced confirmation steps, higher instant-withdrawal limits — for users with scores above 700. Reward trust with speed, and signal to users that a better score unlocks better UX.

Retention
📅

Score-based loyalty programs

Build score tiers into your existing loyalty or fee-discount program. Users whose scores improve over time earn lower trading fees, priority customer support, or exclusive product access.

Retention & product
📊

User profile score badge

Display a verified VIZI® Score badge on user profiles. Gamifies creditworthiness, adds a social proof layer to P2P features, and drives daily score checks that create habitual return visits.

Engagement
Exchange API vs. Standard API

Built specifically for
exchange data environments

The Exchange API variant is enriched with platform-level context you already hold — improving scoring accuracy without additional external data queries.

⚡ Exchange API

Platform-enriched scoring

Pass your platform balance data, trading history, and KYC status alongside the wallet address. VIZI® incorporates this context into the score, improving accuracy for users whose primary activity is on your platform.

Standard API

On-chain only

Standard score pulls query on-chain data only. Accurate for users active on public DeFi protocols, but misses activity that happens on centralized platforms — exactly the gap the Exchange API closes.

⚡ Exchange API

Real-time balance context

Your platform holds the most current view of a user's balance. The Exchange API accepts real-time balance data at call time, preventing gaming via rapid deposits before a score check.

Standard API

Auditable, chain-verified

Every data point in the standard score can be independently verified on-chain. Useful when a lender or regulator needs to audit the inputs — the on-chain record is the source of truth.

Score Gating

Map VIZI® scores directly to
your existing product tiers

Because VIZI® uses the same 300–850 scale as FICO® and VantageScore®, your risk team already knows how to work with the numbers. No calibration required.

Your thresholds, your rules. The tier mapping above is a suggested starting point. Your risk team can set any score cutoffs and combine VIZI® scores with your existing signals. The Exchange API returns the raw score and all 8 signal values — you control the decisioning logic downstream.

Integration

Exchange-enriched API call

Pass platform context alongside the wallet address. The Exchange API accepts an optional platform_context object to enrich scoring.

Exchange API — POST /v1/score
{ "wallet": "0x71C7656EC7ab88b098defB751B7401B5f6d8976F", "chain": "ethereum", "include_signals": true, "include_sanctions": true, "platform_context": { // Exchange API only "platform_balance_usd": 14250.00, "kyc_verified": true, "account_age_days": 847, "trading_volume_90d_usd": 92400.00, "margin_calls_lifetime": 0, "platform_id": "exchange_user_8821" // your internal user ID } } // Response includes an enriched score and a platform_context_applied: true flag // Platform data is processed in-flight and never stored by VIZI
🔒

Platform data is never stored. The platform_context object is processed in-flight during score computation and is not retained by VIZI® after the response is returned. Your user data does not leave your control.

Compliance

One call. Four AML lists.
Real time.

Exchange compliance teams manage a growing list of AML vendors. Every VIZI® Exchange API call consolidates four of the most important into a single response at no extra cost.

🇺🇸

OFAC SDN List

Real-time screening against the U.S. Treasury Office of Foreign Assets Control Specially Designated Nationals list. Every pull, zero configuration.

🇬🇧

OFSI List

UK Office of Financial Sanctions Implementation consolidated list. Supports exchanges operating in or with UK jurisdiction without a second vendor.

🚫

Chainalysis Exposure

Illicit entity exposure risk based on Chainalysis transaction graph data. Flags wallets with direct or indirect exposure to known malicious addresses.

Chainabuse Community Reports
