Immutable variables let Vyper contracts embed constants in bytecode, cutting read costs and storage use. This post explains how they work, shows a real example, highlights trade‑offs, and tells you how to verify the savings in your own project.
Immutable variables in Vyper let you set a value once at deployment, reduce storage gas, and enable compiler inlining. This guide explains when to use them, their trade‑offs, and a step‑by‑step validation workflow.
