    • It requires to call this API as soon as the VASP finds the transaction ID (txHash) now, in contrast to the former version of the guide that required calling it after the transaction finality check.

    • Only required beneficiary information fields need to be filled out.

  • The name of an environmental variable has been changed as User Address Verification API is changed to User Account Verification API.



  • A new environment variable for VASP API Authorization Token header setup has been added.

  • The index definition of commands table updated.

    • A new column created_at is added to the index.

    • See Database page for more details.

Version 1.2.0

Major changes

  • Some enclave APIs were changed to work asynchronously.

    • Data that was delivered with synchronous API response is now delivered through the callback VASP API.

Why did VerifyVASP introduce asynchronous processes?

The user verification process necessarily includes connections to other VASPs whose immediate completion is not able to be guaranteed.

In this situation, synchronous interlocking might result in the burden of staying connected until the response comes, which can be a bottleneck at the time of heavy requests.

Therefore, some APIs are now changed to work in a non-blocking way. Get the processing result through the newly added callback API from now on.

  • Specific personal data specification requirements now can be designated in the request phase to VASP.

    • Refer to the newly added code specification to designate the data requirements.

Background of using personal data field code

When sharing user personal information between VASPs, the required fields might vary along with the policy of each VASP or national regulation.

For example, a VASP may need an additional field such as the date of birth for sanction screening, or geographical address to meet the legal necessities.

Simply including the additionally required data fields upon the request or response enables the VASPs to collect required data without any unnecessary custom precessing. All the verification requester VASPs must fill the requested fields to satisfy the data request, or the verification should be DENIED.

  • VASP API implementation policy updated.

VASP API policies

VerifyVASP, a Travel Rule solution, is a collaborative protocol among multiple VASPs.

Each VASP has its own internal operating policy or different implementation standard, which makes it hard to orchestrate the system to work fine.

Accordingly, building a minimal consensus on the implementation policy can help the counter-side VASP reduce unexceptional errors and build the system easily.

  • Now VerifyVASP supports a transaction in a single VASP, meaning a VASP can be both the originating VASP and beneficiary VASP of the transaction.

Supporting transaction inside a VASP

It is not mandatorily required for the users who trade virtual assets in the same VASP to be verified via VerifyVASP.

However, the VASP might need to operate an additional system to track the verification history of internal transactions under the regulation. Integrating VerifyVASP for both internal and external transactions is recommended to reduce the operational overhead.

Enclave API


  • Callback API is newly added.

    • The API is for getting notifications of the processing result asynchronously.

    • Strongly recommended implementing the callback API: Polling way of implementation for all the processing transaction results without enough care might be a burden to both VASP itself and the VerifyVASP network.

  • Implementation policies for each VASP API were updated.

  • Error codes from the user verification API are now provided.


  • The database table definition was updated.

    • Added: commands table

    • Modified: verifications table

      • message column is added

  • An environmental variable was added

    • VEGA_VERIFICATION_CALLBACK_API_PATH: A variable for callback API endpoint setup


  • IVMS101 Message Format Guide was updated.

    • Address field expansion to support multiple addresses in addition to the parent address (e.g. XPR, EOS)

    • The geographic address policy now requires corporations to fill out both headquarters address and branches.

Bugfix and minor updates

  • The problem in setting database port number adjustment has been fixed.

  • The endpoint scanning process during enclave boot now checks the endpoints of transaction status query API and address verification API too.

  • A diagram describing the transaction state transition has been added to the transaction status query API page.

  • Parameter names have been changed.

    • The query parameters for Verification Result List API are modified as follows. - fromAccount --> originatorAccountNumber - toAccount --> beneficiaryAccountNumber
