Bank messaging platform, SWIFT announced positive results from a pilot test of linking different central bank digital currencies (CBDCs) on 9 March. The 12-week testing period saw the simulation of almost 5,000 transactions between two blockchain networks and existing fiat payment systems, with over 18 financial institutions worldwide participating. SWIFT found that its experimental interlinking solution could meet the needs of central and commercial banks for CBDCs interoperability. It has outlined its plans to conduct a second phase of CBDC sandbox and further develop its “CBDC interlinking solution” into a beta version for payments with enhanced atomicity.
