Verify KYC
Issue on-chain KYC verifications for users, with the approved-KYC-profile prerequisite and a fix for the "No approved KYC profile" block.
KYC verifications attest that an enrolled user has passed the organisation's identity review and can satisfy the asset's compliance checks. Issue the verification only after the trusted issuer setup, identity registry enrolment, and documentation review are complete.
Prerequisites
- Verification Issuer role
- Must be configured as trusted issuer for KYC topics (see Configure Trusted Issuers)
- User must be enrolled in identity registry
- The user must have an approved KYC profile before you can issue a KYC verification. A KYC verification carries the hash of the user's approved profile, so the console cannot issue one until that profile exists. See Before you can issue a KYC verification.
- Completed KYC documentation review
About KYC verifications
KYC verifications are on-chain attestations that confirm:
- User identity has been verified
- Documentation meets compliance standards
- User is eligible for asset transactions
- Verification is issued by a trusted entity
When KYC is required
KYC verification is not automatically required for all users. It becomes necessary when:
Global requirement: The platform's Identity verification compliance module is configured to require KYC verification for all asset transactions. This is recommended as a default security measure.
Per-asset requirement: Individual assets can enable the Identity verification compliance module with KYC as a required verification topic, even if not required globally.
No requirement: Some use cases may not require KYC verification at all, depending on the asset type and regulatory context.
For complete information about verification topics and framework, see Compliance Overview.
Before you can issue a KYC verification
A KYC verification attests to the user's approved KYC profile, so the console can only issue one after that profile exists. If you open the issue-verification form for a KYC topic and the user has no approved profile, the form shows a No approved KYC profile message and the Continue button stays disabled. The verification hash cannot be calculated without an approved profile, so issuance is blocked until one is in place.
This is the most common reason a KYC verification cannot be issued for a registered user. Clear it by completing the KYC profile path first:
- The user submits their KYC profile. The user opens their account profile, completes their identity details and any required documents, and selects Submit for review. See Provide KYC data.
- An Identity Manager approves the submission. A reviewer opens the user's KYC version and selects Approve, which makes that version the approved profile. See Manage KYC data.
- Issue the KYC verification. With an approved profile in place, return to the issue-verification flow below. The No approved KYC profile message clears and you can complete issuance.
A user can be enrolled in the identity registry and still have no approved KYC profile. Registry enrolment links the wallet to an on-chain identity; the approved profile is a separate step the user and a reviewer complete together.
Issuing KYC verifications
Access user verifications
Navigate to Participants > Users and select a user you want to verify. On the user detail page, find the "Identity and verifications" tile and click Manage verifications.
Issue verification
Click Issue verification and select the verification topic you want to issue (KYC, Accredited Investor, AML, or other topics based on your trusted issuer status).
Complete verification process
Click Continue to proceed, review the verification summary, then click Issue verification. Enter your PIN when prompted and wait for transaction confirmation.
Verify completion
After transaction confirmation, the verification appears in the user's verification list with a green shield indicating you were a trusted issuer for this topic. The user can now receive assets requiring this verification.
