Welcome to your central self-service page for the OSTTRA Documentation Centre (ODC) Strategic Upgrade.
OSTTRA is officially transitioning its client network from the legacy Designation Notice Manager (DNM) to our upgraded infrastructure on the OSTTRA Documentation Centre (ODC). This mandatory system upgrade delivers a modern, cloud-hosted interface, streamlined static data management, and expanded agreement capabilities (including 4-Way Agreements and our new Document Framework)—all secured by unified Single Sign-On (SSO).
To ensure an operationally seamless transition for your team and counterparties throughout our phased rollout windows, we have centralized all essential documentation below.
