# 29484 - \[SC - Insight] Potential Loss of Precision in Conversion from ... Submitted on Mar 20th 2024 at 23:27:54 UTC by @Flare for [Boost | Immunefi Arbitration](https://immunefi.com/bounty/immunefiarbitration-boost/) Report ID: #29484 Report type: Smart Contract Report severity: Insight Target: Impacts: * Precision ## Description ## Brief/Intro The `setUp` function in the `WithdrawalSystem` contract involves converting a `uint256` value to a `uint32` for setting the cooldown period for withdrawals. This conversion may lead to a loss of precision and unexpected behavior if the original value exceeds the range representable by a `uint32` ## Vulnerability Details The `setUp` function in the `withdrawlSystem` contract accepts parameters, including `_txCooldown`, which represents the cooldown period for withdrawals. Within the function, the `_txCooldown` value is cast from uint256 to uint32 before being passed to the `_setTxCooldown` function. This type conversion can potentially lead to issues due to loss of precision if the original value is larger than what can be represented by a uint32 ## Impact Details the impact of the potential loss of precision in the conversion from `uint256` to `uint32` ## References change input var \_txCooldown as uint32 in `setUp` function ## Proof of Concept --- # 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.
