EVM implementation for Parity.
Copyright 2015-2020 Parity Technologies (UK) Ltd.
Usage:
openethereum-evm state-test <file> [--json --std-json --std-dump-json --only NAME --chain CHAIN --std-out-only --std-err-only --omit-storage-output --omit-memory-output]
openethereum-evm stats [options]
openethereum-evm stats-jsontests-vm <file>
openethereum-evm [options]
openethereum-evm [-h | --help]
Commands:
state-test Run a state test from a json file.
stats Execute EVM runtime code and return the statistics.
stats-jsontests-vm Execute standard json-tests format VMTests and return
timing statistics in tsv format.
Transaction options:
--code CODE Contract code as hex (without 0x).
--to ADDRESS Recipient address (without 0x).
--from ADDRESS Sender address (without 0x).
--input DATA Input data as hex (without 0x).
--gas GAS Supplied gas as hex (without 0x).
--gas-price WEI Supplied gas price as hex (without 0x).
State test options:
--chain CHAIN Run only from specific chain name (i.e. one of EIP150, EIP158,
Frontier, Homestead, Byzantium, Constantinople,
ConstantinopleFix, Istanbul, EIP158ToByzantiumAt5, FrontierToHomesteadAt5,
HomesteadToDaoAt5, HomesteadToEIP150At5, Berlin, Yolo3).
--only NAME Runs only a single test matching the name.
General options:
--json Display verbose results in JSON.
--std-json Display results in standardized JSON format.
--std-err-only With --std-json redirect to err output only.
--std-out-only With --std-json redirect to out output only.
--omit-storage-output With --std-json omit storage output.
--omit-memory-output With --std-json omit memory output.
--std-dump-json Display results in standardized JSON format
with additional state dump.
Display result state dump in standardized JSON format.
--chain CHAIN Chain spec file path.
-h, --help Display this message and exit.
