Questions and Answers

ECB PUBLIC Questions and Answers Question : Multi-addressee payments Is it possible in T2 RTGS to prevent one Multi-addressee to send a payment as another Multi-addressee of the same direct participant? Example: MAA1 & MAA2 are two multi-addressees allowed to settle payments that will debit the RTGS DCA of DPA1 (direct participant and DCA holder). The DN of MAA1 & MAA2 will both be authorised as PTAs of DPA1 and linked to an A2A user of DPA1 with the proper roles attached; but without inbound DN/BIC routing What can prevent MAA1 to send payments as MAA2? 4 www.ecb.europa.eu ©

Questions and Answers

ECB PUBLIC Questions and Answers Answer: Recap of the scenario MAA1 - multi-addressee participant of DPA1 uses the following data: Technical Sender DN = PTA of MAA1 linked to DPA1 Signature DN = Certificate DN of MAA1 user In the BAH MAA1 uses the BIC of MAA2, i.e. BAH FROM = MAA2 The Business Sending User in the BAH is authorised for DPA1 and the signature DN is linked to the business sending user. As outlined in VR00100, an addressee BIC of the account given in the payload of the payment order (Instructing Agent) is to be used. Given that the BIC of MAA1 as well as the BIC of MAA2 are valid addressee BICs of the relevant account the payment order will be processed. Conclusion:

In the above scenario, MAA1 with its authorized PTA as technical sender could indicate also MAA2 instead of MAA1 as FROM BIC in the BAH. 5 www.ecb.europa.eu ©
