StackOS is an open protocol that allows individuals to collectively offer a decentralized cloud where you can deploy any full-stack application, decentralized app, blockchain privatenets and mainnet nodes.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
StackToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/erc20/StackToken.sol#229-255) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/erc20/StackToken.sol#242-243)
Don't use strict equality to determine if an account has enough Ether or tokens.

StackToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/erc20/StackToken.sol#89-128) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,STACK::delegateBySig: signature expired) (contracts/erc20/StackToken.sol#126)
Avoid relying on block.timestamp.

StackToken.getChainId() (contracts/erc20/StackToken.sol#266-272) uses assembly
- INLINE ASM (contracts/erc20/StackToken.sol#268-270)
Do not use evm assembly.

Different versions of Solidity is used:
- Version used: ['0.6.12', '>=0.6.0<0.8.0']
- >=0.6.0<0.8.0 (@openzeppelin/contracts/math/SafeMath.sol#3)
- >=0.6.0<0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#3)
- >=0.6.0<0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#3)
- >=0.6.0<0.8.0 (@openzeppelin/contracts/utils/Context.sol#3)
- 0.6.12 (contracts/erc20/StackToken.sol#3)
Use one Solidity version.

StackToken._beforeTokenTransfer(address,address,uint256) (contracts/erc20/StackToken.sol#274-280) is never used and should be removed
Remove unused functions.
Additional information: link
Pragma version>=0.6.0<0.8.0 (@openzeppelin/contracts/utils/Context.sol#3) is too complex
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.

Variable StackToken._delegates (contracts/erc20/StackToken.sol#23) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (@openzeppelin/contracts/utils/Context.sol#21)" inContext (@openzeppelin/contracts/utils/Context.sol#15-24)
Remove redundant statements if they congest code but offer no value.

StackToken.constructor(address) (contracts/erc20/StackToken.sol#10-14) uses literals with too many digits:
- amount = 1000000000e18 (contracts/erc20/StackToken.sol#11)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
decreaseAllowance(address,uint256) should be declared external:
- ERC20.decreaseAllowance(address,uint256) (@openzeppelin/contracts/token/ERC20/ERC20.sol#189-192)
Use the external attribute for functions never called from the contract.
