# 56326 sc insight variable could be immutable **Submitted on Oct 14th 2025 at 16:18:58 UTC by @PotEater for** [**Audit Comp | Alchemix V3**](https://immunefi.com/audit-competition/alchemix-v3-audit-competition) * **Report ID:** #56326 * **Report Type:** Smart Contract * **Report severity:** Insight * **Target:** * **Impacts:** ## Description ## Brief/Intro In the `AlchemistV3Position.sol` contract, the declared variable `alchemist` could be immutable. This would significantly save on gas costs during contract initialization and also during contract interactions. ## Vulnerability Details The variable `alchemist` could be set as immutable. This would save on gas costs \~2,100 gas per call, this variable is used in the `onlyAlchemist` modifier. This modifier is used a lot in this contract. ```solidity address public alchemist; ``` Setting this variable to immutable would save gas costs because immutable variables cost less gas when interacted with, because they are not taken from the contract's storage. ## Impact Details This is a code optimization.. This will save \~2,100 gas per interaction with this variable. ## References ## Proof of Concept ## Proof of Concept Setting variable to immutable saves gas, because the contract will not have to read from the contract storage when interacting with this variable. This saves \~2,100 gas per call. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
