Firstly, SCT Inst scheme participants can formally commit to their respective customers to process a SCT Inst transaction faster than the default timeline defined by the scheme.
The second option is that SCT Inst scheme participants can also agree to apply a shorter hard time-out deadline.
With respect to these two SCT Inst scheme options, the default timeline and the hard time-out deadline have already been considerably shortened as of the 2025 SCT Inst rulebook.
A SCT Inst scheme participant must have an agreement with other individual SCT Inst scheme participants, or with communities of SCT Inst scheme participants (e.g., on country-level) before it can support any SCT Inst option.
A list of SCT Inst scheme participants supporting one of these SCT Inst options, and their concrete characteristics, will be made available on this webpage. The EPC will not be responsible for the accuracy and exhaustiveness of such list.
