Shared KYC Utility

Verify once.
Trust everywhere.

Deploy a shared KYC utility where a customer completes verification once and every consortium bank confirms status with consent, without raw data ever being shared. AML alerts propagate in real time, so fraud caught at one bank protects the whole network.

The Foundation

The Execution Mechanics

Turn duplicate per-bank verification into a consent-driven, privacy-preserving shared credential.

01.

Verify-Once Credential

End repeated onboarding. The KYC and Identity Verification module lets a customer complete KYC once and receive a reusable verification credential accepted across the consortium.

02.

Consent-Gated Sharing

Keep the customer in control. A bank can only read a customer's KYC status after the customer grants consent, recorded on-chain for every access.

03.

Zero Raw Data Exposure

Share status, not documents. Banks verify a credential's validity through the DID and VC Ledger without the underlying documents ever leaving the issuing bank.

04.

Provider Adapter Layer

Plug into existing checks. The KYC Provider Adapters module connects each bank's existing verification vendors, so the shared credential builds on checks banks already trust.

05.

Real-Time AML Propagation

Protect the whole network. A negative-list or AML alert raised at one bank propagates to all consortium banks in real time, closing the gap fraudsters exploit.

06.

Auditable Access Trail

Record every look-up. Each consent and verification is logged, so a regulator can audit exactly which bank verified which customer and when.

The KYC Lifecycle

Follow one customer from a single verification to instant credential reuse at two more banks.

Smart Contract Anatomy

Cerulea decomposes shared KYC into modular contracts. Each layer issues a credential, gates consent, verifies without exposing data, and propagates AML alerts across the consortium.

Applicability Across the Spectrum

Shared KYC is a horizontal capability. Here is how different actors put the reusable credential to work.

Consortium Banks

Cut duplicate KYC spend by verifying a shared credential with consent, onboarding customers in minutes while catching fraud through real-time AML propagation.

Network & Execution Architecture

Whether you are bridging a bank's onboarding system or serving customers from a wallet, Cerulea routes both into one shared KYC record.

Track A: Onboarding System Bridging

For banks on legacy onboarding platforms. KYC decisions from existing vendors are translated into signed on-chain credentials through the API gateway automatically.

Track B: Customer Consent Wallet

For customers on a wallet. The customer signs each consent grant and routes it directly to the consent gate before any bank can verify.

Technical Methodology

The legacy timeline reflects consortium identity integration benchmarks. Building reusable credentials, consent gating, privacy-preserving verification, and real-time AML propagation across banks takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your KYC and consent rules into pre-audited WebAssembly binaries and provisions the shared KYC ledger and alert layer instantly.
