ClearstreamXact testing environment

Clearstream provides a permanent, dedicated testing environment that allows clients to simulate a wide range of operations and connectivity solutions in a stable and secure setting. Engaging in testing helps reduce the risks and costs associated with errors that might otherwise occur in the live production environment.

The environment supports testing for all ClearstreamXact connectivity channels, including Xact Web Portal, Xact via Swift and Xact File Transfer (SFTP). It is fully compatible with future-mode Swift, facilitating the testing of messages in both ISO 15022 and, where applicable, ISO 20022 formats.

Clients can access the test environment directly via this link: https://xact-t2s-test.clearstream.com.

Testing options and requests

Clearstream’s testing process is designed to be flexible, supporting the testing of internal instructions, and the format of non-T2S domestic instructions. Clearstream offers two types of testing sessions to suit clients’ needs:

• Guided sessions: These sessions last up to three weeks and include dedicated connectivity support from our team, including matching or settlement of clients’ instructions. At the end of the session, the client’s setup remains active, allowing the client to continue testing independently.
• Independent Sessions: Ideal for clients who prefer to test on their own schedule and only require initial setup preparation.

How to request testing

All requests for client testing must be submitted via the online request form, which is available under Attachments.

When completing the form, please indicate in Question 7 whether a guided session is required.

Where guided testing is requested, clients are asked to limit their proposed testing window to a maximum duration of three weeks.

All testing requests are subject to review in light of current operational capacity. The final testing schedule and window will be mutually agreed upon with the client to ensure appropriate planning and support.

For any enquiries or specific requirements, please contact at the Connectivity Client Testing team at connect-test@clearstream.com.
Client requests will be duly reviewed, and a response will be provided in due course.
