PNT-01C: Redundant Code Imports
| Type | Severity | Location |
|---|---|---|
| Gas Optimization |  | ProtectedNativeTokenGateway.sol:L9, L10, L11, L12, L18, L19 |
Description:
All referenced code imports and use statements are redundant given that they are not actively utilized by any statement in the ProtectedNativeTokenGateway contract's code.
Example:
src/periphery/pToken/ProtectedNativeTokenGateway.sol
4import {Ownable} from '@aave/core-v3/contracts/dependencies/openzeppelin/contracts/Ownable.sol';5import {IERC20} from '@aave/core-v3/contracts/dependencies/openzeppelin/contracts/IERC20.sol';6import {GPv2SafeERC20} from '@aave/core-v3/contracts/dependencies/gnosis/contracts/GPv2SafeERC20.sol';7import {IPool} from '@aave/core-v3/contracts/interfaces/IPool.sol';8import {IAToken} from '@aave/core-v3/contracts/interfaces/IAToken.sol';9import {ReserveConfiguration} from '@aave/core-v3/contracts/protocol/libraries/configuration/ReserveConfiguration.sol';10import {UserConfiguration} from '@aave/core-v3/contracts/protocol/libraries/configuration/UserConfiguration.sol';11import {DataTypes} from '@aave/core-v3/contracts/protocol/libraries/types/DataTypes.sol';12import {DataTypesHelper} from '../libraries/DataTypesHelper.sol';13import {IWBNB} from './interfaces/IWBNB.sol';14import {IPERC20} from './interfaces/IPERC20.sol';15

22 IWBNB internal immutable WBNB;Recommendation:
We advise them to be safely omitted, greatly reducing the bytecode size of the contract.
Alleviation:
All redundant imports and usage statements have been properly omitted, reducing the contract's bytecode size significantly.
