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​

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.
