8.2.3 Interchain Services based on FISCO BCOS

Application Contract Development Guide in BSN production environment

The development of FISCO BCOS application contract is based on its own business scenario. The main implementation includes two parts: if the source chain initiates a cross-chain transaction, its application contract needs to get outbound to access the target chain; if the target chain receives a cross-chain transaction, its application contract needs to get inbound.

BAn example of a specific cross-chain transaction call can be found in Demo Contract Example.
