It is crucial to validate inputs, even if the inputs come from trusted addresses, to avoid human error. A lack of robust input validation can only increase the likelihood and impact in the event of mistakes. Following is the list of places that can potentially benefit from stricter input validation: 1. qs-badge-fixed `ZNSAccessController.sol#77`: the `addresses` of the `_grantRoleToMany()` should not be zero. 2. qs-badge-fixed `ZNSDomainToken.sol#122`: the `royaltyFraction` of the `setDefaultRoyalty()` should be equal to or less than base `10_000`. 3. qs-badge-fixed `ZNSRegistry.sol#60`: the `msg.sender` of the `initialize()` should be a contract. The NatSpec claims the owner of 0x0 is a multisig. 4. qs-badge-acknowledged `ZNSRegistry.sol#262`: the `resolver` interface of the `_setDomainResolver` should be validated before setting the resolver address. 5. qs-badge-acknowledged `ARegistryWired.sol#35`: the `registry_` interface of the `_setRegistry()` should be validated before setting the registry. 6. qs-badge-fixed `ZNSCurvePricer.sol#109`: the `priceConfig.feePercentage` of the `setPriceConfig()` should be equal to or less than `PERCENT_BASIS`. 7. qs-badge-fixed `ZNSCurvePricer.sol#246`: the `feePercentage` of the `setFeePercentage()` should be equal to or less than `PERCENT_BASIS`. 8. qs-badge-fixed `ZNSFixedPricer.sol#130`: the `feePercentage` of the `_setFeePercentage()` should be equal to or less than `PERCENT_BASIS`.
