How It Works

The lender workflow end-to-end

VIZI® scores the wallet. You own the identity linkage. Compliance responsibility maps cleanly to who holds what.

1

Borrower applies

Applicant submits their wallet address alongside the standard loan application. You collect KYC as normal — identity-to-wallet linkage happens on your side.

Your system
2

API score pull

Your system calls POST /v1/score with the wallet address. A 300–850 score with full signal breakdown is returned in under 15 seconds.

VIZI® API
3

Underwriting decision

Score read against your existing cutoffs. A 720 VIZI® Score signals the same creditworthiness as a 720 FICO® score — no translation layer needed.

Your system
4

Your compliance obligations

Having connected identity to wallet, you handle applicable ECOA, adverse action, and any relevant FCRA obligations at this step. VIZI® scored the wallet — you made the credit decision.

Your responsibility

Clean compliance handoff. VIZI® scores wallet addresses — pseudonymous on-chain identifiers. No identity linkage is made or required on our end. When you connect a VIZI® Score to an identified loan applicant, FCRA, ECOA, and adverse action requirements apply to your decisioning process at that step. Your compliance counsel should review how VIZI® fits your regulatory framework. We provide a published methodology and full signal breakdown to support any adverse action explanation requirements.

Why Lenders Integrate

Six reasons to add
the VIZI® Score today

👥

Reach the creditworthy invisible

Millions of creditworthy borrowers have no traditional credit file but years of responsible DeFi borrowing history. VIZI® makes that history legible and actionable for your underwriters.

New segment unlocked

No model retraining

The 300–850 scale is already in your underwriting stack. A VIZI® Score slots in exactly where a FICO® score does. No new thresholds, no new decisioning logic, no new training data needed.

Same scale, zero retrain
📋

Transparent signal breakdown

Every score includes all 8 signal contributions with individual values and weights. Your loan officers see exactly what drove the number — and every weight is published in the public methodology whitepaper.

8 signals returned

OFAC screening at no extra cost

Real-time OFAC SDN and OFSI screening runs on every score pull. Flagged addresses return a compliance alert before you make any decision. One less vendor to manage for crypto-specific AML.

Every pull, included
🔥

Real-time, not monthly

A borrower's on-chain history updates with every block. Unlike traditional bureau data on a 30-day reporting cycle, the VIZI® Score reflects the wallet's state as of the moment of the pull.

Block-level freshness
📈

Competitive differentiation

Crypto-native borrowers are choosing lenders that understand their history. Being an early VIZI® adopter means reaching this growing segment while competitors are still declining them.

Compliance

Built for regulated lenders

VIZI® was designed with the compliance requirements of regulated financial institutions in mind from day one.

📋

Published methodology

Every signal weight, data source, and scoring rule is documented in the public VIZI® Score Methodology Whitepaper. Regulators and auditors can inspect the model. No black box to defend in an exam.

OFAC + OFSI on every pull

Real-time sanctions screening is built into the score API response — not a separate endpoint. Flagged wallets return a compliance alert with the matched list and flagged address details.

🔒

SOC 2 Type II

VIZI® infrastructure is SOC 2 Type II certified. Security, availability, and confidentiality controls are independently audited annually. Audit reports available to enterprise partners under NDA.

Adverse action support

The full signal breakdown returned on every score pull supports adverse action explanation requirements. Individual signal scores and weights are provided for each factor that contributed to the outcome.
