Calling contracts
Overview
The protostar call
command allows you to call any @view
function without mutating the blockchain
state.
The basic inputs that you need for the commands are:
- Contract address
- Function name
- Inputs to the function
- Network you want to target (i.e. its name or gateway URL)
For detailed API description, see call command reference.
Usage example
protostar call --contract-address 0x07ee8ac4d0c1b11eca79b347fb47be5a431cf84a854542b9fbe14f11cfba5466 --function "add_3" --network testnet --inputs 3
Call successful.
Response:
{
"res": 6
}
note
If you need to print machine-readable output in JSON format, you should use --json
flag.
This may come in handy for writing scripts that include protostar commands.
