Immutables should use SCREAMING_SNAKE_CASE

Severity: Info ID: screaming-snake-case-immutable

Flags immutable state variables whose names do not follow SCREAMING_SNAKE_CASE.

What it does

Reports state variables declared immutable whose identifier deviates from SCREAMING_SNAKE_CASE. Single-character names are not checked, and leading and trailing underscores are preserved.

Why is this bad?

The Solidity style guide recommends SCREAMING_SNAKE_CASE for immutable variables so they visually align with constant ones and stand out from mutable state at call sites.

Example

Bad

address immutable owner;
address immutable Owner;

Good

address immutable OWNER;
