Source Code

setRemoteValue(string,string,string) :

This function is used to set a remote value on a different blockchain. It takes three parameters: the destination chain, the destination address, and the value to be set. The function first encodes the value into a byte array, and then checks if the msg.value is greater than 0. If it is, it pays the native gas for the contract call using the gasService.payNativeGasForContractCall function. Finally, it calls the gateway.callContract function with the destination chain, destination address, and payload as parameters. This will set the remote value on the destination chain. (autogenerated documentation)

_execute(string,string) :

This function is an internal override of the _execute() function in the CrossChainBase contract. It decodes the payload data passed to it and stores the source chain and source address in the sourceChain and sourceAddress variables respectively. (autogenerated documentation)
