AMSTERDAM, NETHERLANDS — fairCT B.V., will officially open the User Acceptance Testing (UAT) sandbox for its Data Contributor API on Tuesday, August 4. This sandbox environment will be made available specifically for functional development against the contributors API.
The opening of the UAT environment to receive market data from the trading venues and APA’s marks another core milestone in fairCT’s roadmap for the establishment of the consolidated tape for bonds in the European Union. The opening of fairCT’s User Acceptance Testing (UAT) sandbox for data contributors marks a vital operational milestone toward realizing the core objectives of the European Union’s Savings and Investment Union. Enabling trading venues and APAs to test real-time data feeds in a risk-free environment ensures that, from day one, the Consolidated Tape will deliver the high-quality, continuous market data needed to bridge fragmented European markets and unlock cross-border capital flows.
