SPSHIBA [SpringShiba] Token

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

SPSHIBA.blackLists (#103) is never initialized. It is used in:
- SPSHIBA.transfer(address,uint256) (#104-127)
- SPSHIBA.transferFrom(address,address,uint256) (#164-191)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Pragma version^0.6.0 (#2) allows old versions
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 Address.sendValue(address,uint256) (#41-45):
- (success) = recipient.call{value: amount}() (#43)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#59-74):
- (success,returndata) = target.call{value: weiValue}(data) (#61)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
