Credit & Passport

Credential verification

Verify Fullness credentials and Financial Passport presentations in TypeScript or Python without trusting unverified claims.

Supported Passport types

FullnessIncomePassportCredential
FullnessIncomeThresholdAttestation
FullnessCompositeThresholdAttestation
FullnessFinancialPassport presentation bundles

TypeScript

TypeScript

import { verifyFinancialPassport } from '@fullness/verifier-sdk';

const result = await verifyFinancialPassport(vpJwt, {
  rejectContradictedChecks: true,
});

if (!result.valid) throw new Error(result.error?.message);
console.log(result.holder, result.checks, result.overall_holds);

Python

Python

from fullness_verifier import verify_financial_passport

result = verify_financial_passport(vp_jwt)
if not result["valid"]:
    raise ValueError(result["error"]["message"])
print(result["holder"], result["checks"], result["overall_holds"])

Verification rules

Verify every embedded credential signature against issuer material.
Validate schema, expiry and revocation.
Bind every credential subject to the presentation holder.
Recompute disclosed threshold signals when comparable values are present.
Keep cryptographic validity separate from the business threshold outcome.
