50) This section of the Guidance sets out the two broad types of entities that are able to provide Digital Securities settlement facilities to RIEs and MTFs, as allowed for by MIR Rules 3.8 and 4.3. In choosing a RCH or DSF to utilise for custody operations (MIR 2.10) or settlement (MIR 3.3), a RIE or MTF can only use a RCH or DSF when the FSRA has been able to determine that the relevant settlement facility allows the RIE or MTF to meet its MIR obligations. Further discussion regarding the FSRA's policy position and expectations in relation to these entities is set out below.
