Impossible Finance is a builder-focused multichain ecosystem featuring decentralized incubator, launchpad, and swap.
The IDIA token is the core governance and access token for allocation into our launchpad sales. Users can stake the IDIA token into a variety of sectors and categories to secure allocation into the top project teams launching on Impossible.

Contract name (Impossible Decentralized Incubator Access Token) has length of 47 chars.
Not a direct threat, but may indicate unreliable intentions of developer.
ImpossibleDecentralizedIncubatorAccessToken.depositWithTransferPermit(address,uint256,uint256,uint8,bytes32,bytes32,address) (#320-323) ignores return value by IERC20(underlying).transferWithPermit(target,address(this),value,deadline,v,r,s) (#321)
Ensure that all the return values of the function calls are used.

ImpossibleDecentralizedIncubatorAccessToken.constructor(string,string,uint8,address,address)._vault (#278) lacks a zero-check on :
- vault = _vault (#293)
- pendingVault = _vault (#294)
Check that the address is not zero.

ImpossibleDecentralizedIncubatorAccessToken.transferWithPermit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#461-485) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,AnyswapV3ERC20: Expired permit) (#462)
Avoid relying on block.timestamp.

solc-0.8.2 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in SafeERC20.callOptionalReturn(IERC20,bytes) (#101-112):
- (success,returndata) = address(token).call(data) (#105)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable ImpossibleDecentralizedIncubatorAccessToken.DOMAIN_SEPARATOR (#125) is not in mixedCase
Follow the Solidity naming convention.
Additional information: link
ImpossibleDecentralizedIncubatorAccessToken.pendingDelay (#154) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
Swapout(uint256,address) should be declared external:
- ImpossibleDecentralizedIncubatorAccessToken.Swapout(uint256,address) (#257-263)
Use the external attribute for functions never called from the contract.
