描述

Issue

Sig hasher is currently written in the deprecated Serpent. We should stop relying on Serpent compiler.

Proposed implementation

  • Migrate current sig hasher from serpent to vyper LLL
  • Port contract to this repo
  • Add sanity check testing to pytest build
  • Compile Purity Checker from source instead of using bytecode in the testing setup

Example Vyper LLL and compile techniques here https://github.com/ethereum/casper/blob/master/tests/utils/valcodes.py
