KYC Platform Overview

The KYC platform onboards your customers - natural persons and corporates - and keeps them compliant over their lifetime. It collects the required data through questionnaires and documents, performs compliance screening (PEP, sanctions, criminal, adverse media), risk assessment, and ongoing due diligence, and reports progress to your application through webhooks.

Integration follows one pattern everywhere:

  1. Create the entity - a Person for retail customers, or a Corporate with its linked Individuals.
  2. Trigger an Entitlement - a capability workflow such as onboarding, derivatives access, or a deposit-limit upgrade.
  3. Fulfil the requirements delivered via requirementsQuestionnaire webhooks (questionnaires and document uploads).
  4. Receive the outcome via the completion webhooks (entitlementCompleted / entitlementFailed).

Onboarding Flows at a Glance​

Which onboarding flow applies to your integration is fixed by your entitlement configuration, agreed during integration setup - it is not selected per request.

A standard KYB variant - platform-performed IDV of the Business Contact - is in development; today, all corporate onboarding uses the reliance flow.

After onboarding, further entitlements cover derivatives access, deposit-limit upgrades (PoSoF), and the DLT-initiated review processes (Ad Hoc EDD, RFI).

"Retail" in these docs

"Retail" generally refers to Person accounts (retail customers), as opposed to Corporates. The Derivatives pages additionally use retail client in its MiFID classification sense (e.g., the Qualified Retail entitlement) - there, it describes the investor category, not the owner type.
