When the Starknet compiler is installed, you can view this command-line help in a terminal by entering the following command: starknet-compile --help Usage starknet-compile [-h] [--abi ABI] [--disable_hint_validation] [--account_contract] [--dont_filter_identifiers] [-v] [--prime PRIME] [--cairo_path CAIRO_PATH] [--preprocess] [--output OUTPUT] [--no_debug_info] [--debug_info_with_source] [--cairo_dependencies CAIRO_DEPENDENCIES] [--no_opt_unused_functions] file [file ...] Example The following example compiles the file contract.cairo. It generates two files: contract_compiled.json The contract class. This file contains the bytecode and all other information necessary to execute a contract. For information on contract classes, see Contract classes. contract_abi.json The contract’s ABI. starknet-compile contract.cairo \ --output contract_compiled.json \ --abi contract_abi.json Description A tool to compile Starknet contracts.
