napalm-core 0.1.2

Your project to manage napalm detection modules

🔥 Napalm Package: napalm-core

This is an automatically generated report on the detectors in this package.

Some quick stats:

• 3 collections
• 19 detectors

optimisations modules:

ID	Description	Severity
storage-variable-bool	Using bool as a storage variable is more expensive than uint256 or other types that fill a whole 256 bit word.	INFO
cache-array-length-loop	The compiler will re-execute each instance of .length for each loop iteration. Caching the length will reduce the amount of sloads necessary to perform the operation.	INFO
initialize-default-value	Initializing variables with their default value leads to unnecessary gas expenditure	INFO

indicators modules:

ID	Description	Severity
math-in-unsafe-block	Mathematical operators in unsafe blocks are not checked for under flows or overflows.	INFO
use-of-privilege-to-protect-sensitive-functions	It's necessary to implement proper controls on wallet security when privileged functions are used to protect sensitive functions.	INFO
import-safetransfer-solmate	Solmate's SafeTransferLib doesn't perform the same checks SafeERC20 does, in particular it doesn't check if a contract exists leading to potential vulnerabilities.	INFO
block-number-l2	Solidity's block.number semantics are not consistent on L2s, leading to potential vulnerabilities.	INFO
push-0-solc-version	Your solidity version uses PUSH0 which is not supported by all chains.	INFO

detectors modules:

ID	Description	Severity
int-cast-block-timestamp	Casting block.timestamp can lead to reduced precision and unexpected behavior, consider not casting instead.	WARNING
use-of-unsafe-erc20-functions	The ERC20 implementation does not automatically include checks that ensure the success of the operation. Using the OpenZeppelin's SafeERC20 library is recommended.	INFO
block-timestamp-swap	Passing block.timestamp as the deadline effectively removes the deadline functionality which prevents malicious validators from holding back transactions to execute them at a later time.	WARNING
dos-push-array-loop	Potential Denial of Service when users can push to an array that's irreducible and looped over.	HIGH
chainlink-circuit-breaker	Vulnerable to exploitation in case of a Chainlink circuit breaker event.	HIGH
unchecked-create-2	Unchecked return value for CREATE2 call.	MEDIUM
unchecked-approve	Unchecked token approve	HIGH
unchecked-equation-modifier	Potential lack of input control due to missing requires checks.	HIGH
erc721-transfer-from-stuck	transferFrom call on ERC721 can lead to stuck tokens	HIGH
erc721-mint-stuck	_mint call on ERC721 can lead to stuck tokens	HIGH
erc20-approve-call	Potential Denial of Service when tokens don't implement approve() consistently ( e.g. USDT ).	HIGH
