Why

We have a bytes.cairo file inherited from Kakarot where we couldn't write hints. This lib is suspected to be inefficient for standard conversions to fixed size types.

What

Write conversion utils in ethereum.base_types for fixed size types with custom hints.

How

This will depend on the data layout strategy for bytes in keth

  • 1 byte per felt ?
  • 8 bytes per felt ?
  • 31 bytes per felt ?
