In CAST, there are three types of settlement technological configurations:
| Settlement technological configuration | Delivery leg | Payment leg |
|---|---|---|
| Cross-chain | Chain X | Chain Y |
| Mono-chain | Chain X | Chain X |
| Hybrid | Chain X | Current payment system |
For the Cross-chain and Hybrid models, there are two settlement centres (places of settlement):
- one for the delivery leg,
- the other one for the payment leg.
