# High Issues
## H-1: `abi.encodePacked()` Hash Collision
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, preventing hash collisions: https://docs.soliditylang.org/en/v0.8.13/abi-spec.html#non-standard-packed-mode. (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: https://ethereum.stackexchange.com/questions/30912/how-to-compare-strings-in-solidity#answer-82739. If all arguments are strings and or bytes, `bytes.concat()` should be used instead.

```
</details>
## H-2: Arbitrary `from` Passed to `transferFrom`
Passing an arbitrary `from` address to `transferFrom` (or `safeTransferFrom`) can lead to loss of funds, because anyone can transfer tokens from the `from` address if an approval is made.

## H-3: Constant functions changes state
Function is declared constant/view but it changes state. Ensure that the attributes of contract compiled prior to 0.5 are correct.
<details><summary>1 Found Instances</summary>
- Found in src/ConstFuncChangeState.sol [Line: 8](../tests/contract-playground/src/ConstFuncChangeState.sol#L8)
```solidity
function changeState() public view returns (uint) {
```
</details>
## H-4: Contract locks Ether without a withdraw function
It appears that the contract includes a payable function to accept Ether but lacks a corresponding function to withdraw it, which leads to the Ether being locked in the contract. To resolve this issue, please implement a public or external function that allows for the withdrawal of Ether from the contract.

## H-5: Dangerous unary operator

## H-7: Deletion from a nested mapping
A deletion in a structure containing a mapping will not delete the mapping. The remaining data may be used to compromise the contract.

## H-8: Direct assignment of array length
If the length of a dynamic array (storage variable) is directly assigned to, it may allow access to other storage slots by tweaking it's value. This practice has been deprecated in newer Solidity versions

## H-9: EnumerableSet.remove Corrupts Order
If the order of an EnumerableSet is required, removing items in a loop using `at` and `remove` corrupts this order.
Consider using a different data structure or removing items by collecting them during the loop, then removing after the loop.

## H-21: Out of Order Retryable Transaction
Do not rely on the order or successful execution of retryable tickets. Functions like createRetryableTicket, outboundTransferCustomRefund, unsafeCreateRetryableTicket are free to be re-tried in any

order of these transactions. Therefore, restrict the use to at most 1 ticket call per function.

## H-27: Signed integer array in storage (solc `<0.5.10`)

## H-28: Shadowed State Variable
This vulnerability arises when a derived contract unintentionally shadows a state variable from a parent contract by declaring a variable with the same name. This can be misleading. To prevent this, ensure variable names are unique across the inheritance hierarchy or use proper visibility and scope controls.

## H-34: Unchecked Low level calls
The return value of the low-level call is not checked, so if the call fails, the Ether will be locked in the contract. If the low level is used to prevent blocking operations, consider logging failed calls. Ensure that the return value of a low-level call is checked or logged.

## H-35: Unchecked `bool success` value for ETH send
The call `address(payable?).send(address)` may fail because of reasons like out-of-gas, invalid recipient address or revert from the recipient, but not revert the transaction.

## H-37: Unsafe Casting of integers
Downcasting int/uints in Solidity can be unsafe due to the potential for data loss and unintended behavior.When downcasting a larger integer type to a smaller one (e.g., uint256 to uint128), the value may exceed the range of the target type,leading to truncation and loss of significant digits. Use OpenZeppelin's SafeCast library to safely downcast integers.

## H-38: Weak Randomness
The use of keccak256 hash functions on predictable values like block.timestamp, block.number, or similar data, including modulo operations on these values, should be avoided for generating randomness, as they are easily predictable and manipulable. The `PREVRANDAO` opcode also should not be used as a source of randomness. Instead, utilize Chainlink VRF for cryptographically secure and provably random values to ensure protocol integrity.

## L-2: Using `block.timestamp` for swap deadline offers no protection
In the PoS model, proposers know well in advance if they will propose one or consecutive blocks ahead of time. In such a scenario, a malicious validator can hold back the transaction and execute it at a more favourable block number.Consider allowing function caller to specify swap deadline input parameter.

## L-12: `ecrecover` Signature Malleability
The `ecrecover` function is susceptible to signature malleability. This means that the same message can be signed in multiple ways, allowing an attacker to change the message signature without invalidating it. This can lead to unexpected behavior in smart contracts, such as the loss of funds or the ability to bypass access control. Consider using OpenZeppelin's ECDSA library instead of the built-in function.

## L-17: Inconsistent uint256/uint (or) int256/int types
Inconsistency in declaring uint256/uint (or) int256/int variables within a contract. Use explicit size declarations (uint256 or int256). Consider keeping the naming convention consistent in a given contract. Explicit size declarations are preferred (uint256, int256) over implicit ones (uint, int) to avoid confusion.

## L-27: PUSH0 Opcode
Solc compiler version 0.8.20 switches the default target EVM version to Shanghai, which means that the generated bytecode will include PUSH0 opcodes. Be sure to select the appropriate EVM version in case you intend to deploy on a chain other than mainnet like L2 chains that may not support PUSH0, otherwise deployment of your contracts will fail.

## L-30: Return Bomb
A low level callee may consume all callers gas unexpectedly. Avoid unlimited implicit decoding of returndata on calls to unchecked addresses. You can limit the gas by passing a gas limit as an option to the call. For example, `unknownAddress.call{gas: gasLimitHere}("calldata")` That would act as a safety net from OOG errors.

## L-31: Solmate's SafeTransferLib
There is a subtle difference between the implementation of solmate's SafeTransferLib and OZ's SafeERC20: OZ's SafeERC20 checks if the token is a contract or not, solmate's SafeTransferLib does not.
https://github.com/transmissions11/solmate/blob/main/src/utils/SafeTransferLib.sol#L9
