Model multi-CBDC payment-versus-payment settlement across mBridge participant corridors. Select your CBDCs, design the settlement mechanism, diagnose time-zone overlap windows, and assess interoperability — then export a Policy Mandate for your architecture decision record.
Select 2–5 CBDC participants. Choose your origin and destination CBDC, transaction type, and size. mBridge MVP participants are pre-loaded; additional CBDCs reflect emerging interoperability candidates.
Select participants (2–5):
Design the settlement architecture: PvP atomicity, bridge layer, ISO 20022 message type, and FX discovery mechanism. mBridge uses a custom DLT ledger; hybrid options incorporate existing RTGS nostro rails.
