Abstract

This standard proposes a mechanism to allow setting components’ configurable constants in the implementing contracts without needing to save them in storage. Component providers can leverage this standard to make them configurable while keeping the constants hardcoded in the bytecode, removing the extra storage reads required if storage were to be used for this matter.
