Disassemble an EVM bytecode string and print the instruction names and operands.

from evmdasm import EvmCode bytecode = "0x60606040526000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff1680600357" codes = EvmCode(bytecode) codes.disassemble() for instruction in codes.instructions: print(instruction.name, instruction.operand)

Debug

Known issues

gotchaEvmCode expects a hex string without '0x' prefix. If you include '0x', it may silently fail or raise an exception.

fix

Strip the '0x' prefix before passing to EvmCode: EvmCode(bytecode[2:])

affects: all

gotchaThe 'disassemble()' method returns nothing; it populates the 'instructions' attribute. A common mistake is to assign the return value, which is None.

fix

Call codes.disassemble() and then access codes.instructions.

affects: all
