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.

Philosophy

A supplement, not a replacement

VIZI® is not competing with your existing credit infrastructure. We are adding a new data source to it. Think of the VIZI® Score as a second opinion from a parallel financial system that your current tools cannot see.

Your underwriting stack stays exactly as it is

You have bureau pulls, income verification, debt-to-income models, fraud checks, and decisioning engines that took years to build and calibrate. None of that changes.

The VIZI® Score adds a single new field to your application data. It answers one question your existing data cannot: what does this borrower's on-chain financial history look like?

  • Same 300–850 scale — no translation layer needed
  • Fits into existing cutoff logic and risk tiers
  • No model retraining, no new decisioning framework
  • Works alongside FICO®, VantageScore®, and internal models
  • You decide the weight — advisory only, or a full input to your model

The Parallel

The FICO® analogy that makes this click

Before FICO®, lenders relied on gut instinct and personal relationships

In the 1950s, most lending decisions were subjective. A loan officer looked you in the eye, asked about your job, and made a judgment call. That system was inconsistent, biased, and left huge populations invisible to credit markets.

FICO® changed that by reducing traditional financial behavior to a single, standardized number. Suddenly, every lender could speak the same language.

That's exactly what's happening in crypto right now. DeFi borrowers are making and repaying loans every day across dozens of protocols. Their repayment history, collateral management, and financial behavior are all recorded on-chain — permanently, transparently, and verifiably. But without a standardized score, that data is unusable for traditional underwriters.

VIZI® is the translation layer. We read the blockchain the way FICO® reads credit bureau files — and output a number your systems already understand.

The key differences

  • Immutable data source. Bureau files can contain errors (26% do, per the FTC). Blockchain records are mathematically verified and cannot be retroactively altered.
  • Real-time, not monthly. Bureau data updates on a 30-day reporting cycle. VIZI® scores reflect the wallet's state at the moment of the pull.
  • No self-reporting dependency. Bureau data relies on creditors voluntarily reporting. On-chain data exists regardless of anyone's willingness to share it.
  • Globally portable. FICO® is US-centric. VIZI® works for any wallet on any supported chain, from any country. The blockchain doesn't have borders.
  • Published methodology. Every signal weight in the VIZI® Score is documented in a public whitepaper. Regulators, auditors, and borrowers can inspect the model.
The Opportunity

Who are these borrowers?

They are not edge cases. They are a growing segment of financially sophisticated individuals who happen to operate primarily in crypto. Your competitors are already looking for ways to reach them.

1.8B

Globally unbanked adults

Nearly two billion adults worldwide have no access to traditional banking or credit systems. Many are building financial histories on-chain that no bureau can see.

47%

Crypto holders with no credit file

Almost half of crypto holders in the US are credit-invisible or have thin files. They are actively borrowing and lending on-chain — just not where your systems can see.

$180B+

Active DeFi TVL

Billions of dollars are locked in decentralized lending protocols right now. These borrowers are managing collateral, making repayments, and building credit histories in real time.

26%

Bureau error rate

Per the FTC, one in four traditional credit reports contains material errors. On-chain data is mathematically verified and cannot be retroactively altered by any party.

3.2x

Higher origination volume

Early VIZI® lender partners report significantly higher origination volumes in the crypto-native segment compared to bureau-only underwriting approaches.

Cost to the borrower

Unlike traditional credit pulls that can affect a borrower's score, VIZI® pulls are invisible to the wallet holder. No consent friction, no score impact, no adverse effects.

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.

Use Cases

How different lenders use VIZI®

The same API, the same score — but the integration pattern varies depending on your lending model. Here's how different lender types are deploying VIZI® today.

DeFi Lending Protocols

Use VIZI® scores to offer under-collateralized loans to high-score wallets. A 720+ VIZI® Score can reduce collateral requirements from 150% to 110%, unlocking capital efficiency for your best borrowers while maintaining portfolio safety.

Mortgage Lenders

Supplement bureau data for crypto-native applicants who hold significant digital assets but have thin traditional files. VIZI® provides evidence of financial responsibility that manual bank statement reviews miss entirely.

Credit Card Issuers

Pre-qualify crypto-native applicants for card products using on-chain credit history. VIZI® enables issuers to reach a segment that would otherwise be declined at the application stage due to no bureau file.

Auto Lenders

Accept crypto income and on-chain credit history as supplementary evidence for auto loan applications. VIZI® scores help auto lenders expand their addressable market without increasing portfolio risk.

Peer-to-Peer Lending

Give individual lenders on P2P platforms a standardized way to evaluate borrower risk. VIZI® replaces ad-hoc wallet inspection with a single number that both sides of the marketplace understand.

Institutional / Prime Brokerage

Score institutional counterparties and fund wallets for margin and lending facilities. VIZI® Institutional Scores provide enterprise-grade risk assessment for treasury and fund-level wallets with complex on-chain activity.

Chain Coverage

One API. Every major chain.

VIZI® reads borrower history across all major L1s and L2s. Your borrowers aren't limited to one chain — and neither are you. Cross-chain activity is aggregated into a single unified score.

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.

Privacy

What we see. What we don't.

The line between VIZI®'s responsibility and yours is clear by design. We built the system so that sensitive identity data never crosses the boundary.

VIZI® sees

  • Wallet addresses (public, pseudonymous identifiers)
  • On-chain transaction history across supported chains
  • DeFi protocol interactions (borrows, repayments, liquidations)
  • Collateral positions, wallet age, and balance patterns
  • Sanctions list match status (OFAC SDN, OFSI)

VIZI® never sees

  • Your borrower's name, SSN, or any PII
  • The identity-to-wallet linkage (that stays on your side)
  • Your underwriting decision or loan terms
  • Whether the applicant was approved or declined
  • Any data from your other vendors or bureau pulls

Zero PII storage. VIZI® does not store, process, or transmit any personally identifiable information. The wallet address is the only input. The score, signals, and sanctions status are the only outputs. This architecture means VIZI® is not a consumer reporting agency under the FCRA and does not trigger GLBA data-sharing obligations.
