SIGNIN Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

SignIn (#5-147) has incorrect ERC20 function interface:SignIn.transfer(address,uint256) (#61-63)
Set the appropriate return values and types for the defined ERC20 functions.

Pragma version^0.4.16 (#1) allows old versions
solc-0.4.26 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.

SignIn.decimals (#9) should be constant
SignIn.name (#7) should be constant
SignIn.symbol (#8) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

SignIn.totalSupply (#11) is set pre-construction with a non-constant function or state variable:
- 1000 * 1000 * 1000 * 10 ** decimals
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
