Calling approve() without first calling approve(0) if the current approval is non-zero will revert with some tokens, such as Tether (USDT). While Tether is known to do this, it applies to other tokens as well, which are trying to protect against this attack vector. safeApprove() itself also implements this protection. Always reset the approval to zero before changing it to a new value, or use safeIncreaseAllowance()/safeDecreaseAllowance()

It is often better to declare addresses as immutable, and assign them via constructor arguments. This allows the code to remain the same across deployments on different networks, and avoids recompilation when addresses need to change.

NFT thefts have increased recently, so with the addition of hacked NFTs to the platform, NFTs can be converted into liquidity. To prevent this, I recommend adding the denylist function.
Marketplaces such as Opensea have a denylist feature that will not list NFTs that have been reported theft, NFT projects such as Manifold have denylist functions in their smart contracts.
Here is the project example; Manifold
modifier nonDenylistRequired(address extension) {
require(!_denylistedExtensions.contains(extension), "Extension denylisted");
_;
}

In solidity versions 0.8.13 and 0.8.14, there is an optimizer bug where, if the use of a variable is in a separate assembly block from the block in which it was stored, the mstore operation is optimized out, leading to uninitialized memory. The code currently does not have such a pattern of execution, but it does use mstores in assembly blocks, so it is a risk for future changes. The affected solidity versions should be avoided if at all possible.

Division by large numbers may result in the result being zero, due to solidity not supporting fractions. Consider requiring a minimum amount for the numerator to ensure that it is always larger than the denominator

ecrecover() accepts as valid, two versions of signatures, meaning an attacker can use the same signature twice, or an attacker may be able to front-run the original signer with the altered version of the signature, causing the signer's transaction to revert due to nonce reuse. Consider adding checks for signature malleability, or using OpenZeppelin's ECDSA library to perform the extra checks necessary in order to prevent malleability.

When there are hard forks, users often have to go through many hoops to ensure that they control ownership on every fork. Consider adding require(1 == chain.chainId), or the chain ID of whichever chain you prefer, to the functions below, or at least include the chain ID in the URI, so that there is no confusion about which chain is the owner of the NFT.

The Openzeppelin’s Ownable used in this project contract implements renounceOwnership. This can represent a certain risk if the ownership is renounced for any other reason than by design. Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.

The non-upgradeable standard version of OpenZeppelin’s library are inherited / used by the contracts. It would be safer to use the upgradeable versions of the library contracts to avoid unexpected behaviour.
Where applicable, use the contracts from @openzeppelin/contracts-upgradeable instead of @openzeppelin/contracts. See this for list of available upgradeable contracts

The compiler for Solidity 0.8.20 switches the default target EVM version to Shanghai, which includes the new PUSH0 op code. This op code may not yet be implemented on all L2s, so deployment on these chains will fail. To work around this issue, use an earlier EVM version

Taking 0 as a valid argument in Solidity without checks can lead to severe security issues. A historical example is the infamous 0x0 address bug where numerous tokens were lost. This happens because 0 can be interpreted as an uninitialized address, leading to transfers to the 0x0 address, effectively burning tokens. Moreover, 0 as a denominator in division operations would cause a runtime exception. It's also often indicative of a logical error in the caller's code. It's important to always validate input and handle edge cases like 0 appropriately. Use require() statements to enforce conditions and provide clear error messages to facilitate debugging and safer code.

This project's specific package versions are vulnerable to the specific CVEs listed below. Consider switching to more recent versions of these packages that don't have these vulnerabilities.
-CVE-2023-26488 - MEDIUM - OpenZeppelin Contracts is a library for secure smart contract development. The ERC721Consecutive contract designed for minting NFTs in batches does not update balances when a batch has size 1 and consists of a single token. Subsequent transfers from the receiver of that token may overflow the balance as reported by balanceOf. The issue exclusively presents with batches of size 1. The issue has been patched in 4.8.2. (@openzeppelin/contracts >=4.8.0 <4.8.2)-CVE-2023-30541 - MEDIUM - OpenZeppelin Contracts is a library for secure smart contract development. A function in the implementation contract may be inaccessible if its selector clashes with one of the proxy's own selectors. Specifically, if the clashing function has a different signature with incompatible ABI encoding, the proxy could revert while attempting to decode the arguments from calldata. The probability of an accidental clash is negligible, but one could be caused deliberately and could cause a reduction in availability. The issue has been fixed in version 4.8.3. As a workaround if a function appears to be inaccessible for this reason, it may be possible to craft the calldata such that ABI decoding does not fail at the proxy and the function is properly proxied through. (@openzeppelin/contracts >=3.2.0 <4.8.3)-CVE-2023-30542 - HIGH - OpenZeppelin Contracts is a library for secure smart contract development. The proposal creation entrypoint (propose) in GovernorCompatibilityBravo allows the creation of proposals with a signatures array shorter than the calldatas array. This causes the additional elements of the latter to be ignored, and if the proposal succeeds the corresponding actions would eventually execute without any calldata. The ProposalCreated event correctly represents what will eventually execute, but the proposal parameters as queried through getActions appear to respect the original intended calldata. This issue has been patched in 4.8.3. As a workaround, ensure that all proposals that pass through governance have equal length signatures and calldatas parameters. (@openzeppelin/contracts >=4.3.0 <4.8.3)

[N-02] abi.encodePacked() should not be used with dynamic types when passing the result to a hash function such as keccak256()
Use abi.encode() instead which will pad items to 32 bytes, which will prevent hash collisions (e.g. abi.encodePacked(0x123,0x456) => 0x123456 => abi.encodePacked(0x1,0x23456), but abi.encode(0x123,0x456) => 0x0...1230...456). "Unless there is a compelling reason, abi.encode should be preferred". If there is only one argument to abi.encodePacked() it can often be cast to bytes() or bytes32() instead.
If all arguments are strings and or bytes, bytes.concat() should be used instead

In Solidity, while function overriding allows for functions with the same name to coexist, it is advisable to avoid this practice to enhance code readability and maintainability. Having multiple functions with the same name, even with different parameters or in inherited contracts, can cause confusion and increase the likelihood of errors during development, testing, and debugging. Using distinct and descriptive function names not only clarifies the purpose and behavior of each function, but also helps prevent unintended function calls or incorrect overriding. By adopting a clear and consistent naming convention, developers can create more comprehensible and maintainable smart contracts.

Large code bases, or code with lots of inline-assembly, complicated math, or complicated interactions between multiple contracts, should implementinvariant fuzzing tests. Invariant fuzzers such as Echidna require the test writer to come up with invariants which should not be violated under any circumstances, and the fuzzer tests various inputs and function calls to ensure that the invariants always hold. Even code with 100% code coverage can still have bugs due to the order of the operations a user performs, and invariant fuzzers, with properly and extensively-written invariants, can close this testing gap significantly.

To maintain readability in code, particularly in Solidity which can involve complex mathematical operations, it is often recommended to limit the number of arithmetic operations to a maximum of 2-3 per line. Too many operations in a single line can make the code difficult to read and understand, increase the likelihood of mistakes, and complicate the process of debugging and reviewing the code. Consider splitting such operations over more than one line, take special care when dealing with division however. Try to limit the number of arithmetic operations to a maximum of 3 per line.

While 100% code coverage does not guarantee that there are no bugs, it often will catch easy-to-find bugs, and will ensure that there are fewer regressions when the code invariably has to be modified. Furthermore, in order to get full coverage, code authors will often have to re-organize their code so that it is more modular, so that each component can be tested separately, which reduces interdependencies between modules and layers, and makes for code that is easier to reason about and audit.

Index event fields make the field more quickly accessible to off-chain tools that parse events. This is especially useful when it comes to filtering based on an address. However, note that each index field costs extra gas during emission, so it's not necessarily best to index the maximum allowed per event (three fields). Where applicable, each event should use three indexed fields if there are three or more fields, and gas usage is not particularly of concern for the events in question. If there are fewer than three applicable fields, all of the applicable fields should be indexed.

[N-53] Expressions for constant values such as a call to keccak256(), should use immutable rather than constant
While it doesn't save any gas because the compiler knows that developers often make this mistake, it's still best to use theright tool for the task at hand. There is a difference between constant variables and immutable variables, and they shouldeach be used in their appropriate contexts. constants should be used for literal values written into the code, and immutablevariables should be used for expressions, or values calculated in, or passed into the constructor.

Use a solidity version of at least 0.8.13 to get the ability to use using for with a list of free functions In 0.8.15 the conditions necessary for inlining are relaxed. Benchmarks show that the change significantly decreases the bytecode size (which impacts the deployment cost) while the effect on the runtime gas usage is smaller.In 0.8.17 prevent the incorrect removal of storage writes before calls to Yul functions that conditionally terminate the external EVM call; Simplify the starting offset of zero-length operations to zero. More efficient overflow checks for multiplication.

Code base has an extensive use of named function calls, but it somehow missed one instance where this would be appropriate. It should use named function calls on function call, as such:
library.exampleFunction{value: _data.amount.value}({
_id: _data.id,
_amount: _data.amount.value,
_token: _data.token,
_example: "", _metadata: _data.metadata

Consider implementing a two-step procedure for updating protocol addresses, where the recipient is set as pending, and must 'accept' the assignment by making an affirmative call. A straight forward way of doing this would be to have the target contracts implement EIP-165, and to have the 'set' functions ensure that the recipient is of the right interface type.

Due to how constant variables are implemented (replacements at compile-time), an expression assigned to a constant variable is recomputed each time that the variable is used, which wastes some gas.

public functions that aren't used internally in Solidity contracts should be made external to optimize gas usage and improve contract efficiency. external functions can only be called from outside the contract, and their arguments are directly read from the calldata, which is more gas-efficient than loading them into memory, as is the case for public functions. By using external visibility, developers can reduce gas consumption for external calls and ensure that the contract operates more cost-effectively for users. Moreover, setting the appropriate visibility level for functions also enhances code readability and maintainability, promoting a more secure and well-structured contract design.
