|
| S8.2.A2 |
Protect against potential DoS in functions like supportsERC165InterfaceUnchecked() by handling excessive data queries efficiently. |
|

✓ |
|
| S8.2.A3 |
Ensure that assertions do not lead to denial of service or unexpected contract reverts, especially in scenarios where conditions are not met. |
|
✓ |
✓ |
|
| S8.2.A4 |
Verify that return values from external function calls are checked to prevent issues related to unchecked return values, which could lead to unexpected behavior. |

✓ |
|
| S8.2.A5 |
Ensure that contract functions are protected against denial of service due to unexpected reverts by handling all possible error conditions appropriately. |

✓ |
|
| S8.2.A6 |
Ensure that functions such as supportsERC165InterfaceUnchecked() in ERC165Checker.sol handle large data queries efficiently to avoid excessive resource consumption. |
