    ethabi encode params [-v <type> <param>]... [-l | --lenient]
    ethabi decode function <abi-path> <function-name> <data>
    ethabi decode params [-t <type>]... <data>
    ethabi decode log <abi-path> <event-name> [-l <topic>]... <data>
    ethabi -h | --help

Options:
    -h, --help         Display this message and exit.
    -l, --lenient      Allow short representation of input params.

Commands:
    encode             Encode ABI call.
    decode             Decode ABI call result.
    abi                Load json ABI from file.
    params             Specify types of input params inline.
    log                Decode event log.
