TGold [Terra Gold] Token

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

TerraGold._tFeeTotal (#87) is never initialized. It is used in:
- TerraGold.totalFees() (#179-181)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

TerraGold.totalSupply (#83) shadows:
- BEP20Basic.totalSupply (#54)
Remove the state variable shadowing.

Pragma version^0.4.26 (#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.

TerraGold.getTokens() (#216-273) uses timestamp for comparisons
Dangerous comparisons:
- msg.value >= requestMinimum && now < deadline && now < round1 && now < round2 (#227)
- msg.value >= requestMinimum && now < deadline && now > round1 && now < round2 (#235)
- now >= deadline && now >= round1 && now < round2 (#257)
Avoid relying on block.timestamp.

TerraGold.getTokens() (#216-273) compares to a boolean constant:
-Claimed[investor] == false && progress0drop <= target0drop (#249)
Remove the equality to the boolean constant.

TerraGold._previousTaxFee (#89) is set pre-construction with a non-constant function or state variable:
- _taxFee
TerraGold._previousLiquidityFee (#91) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.
