USTC Token

USTC.withdraw(address,uint256) (#215-217) sends eth to arbitrary user
Dangerous calls:
- address(target).transfer(amount) (#216)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Additional information: link

USTC.withdrawToken(address,address,uint256) (#219-225) ignores return value by IERC20(token).transfer(target,amount) (#224)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

USTC.withdraw(address,uint256).target (#215) lacks a zero-check on :
- address(target).transfer(amount) (#216)
Check that the address is not zero.

Pragma version^0.8.9 (#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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.

USTC.slitherConstructorVariables() (#134-250) uses literals with too many digits:
- GasToken = 0x0000000000004946c0e9F43F4Dee607b0eF1fA1c (#146)
Use: Ether suffix, Time suffix, or The scientific notation

USTC.name (#135) should be constant
USTC.symbol (#136) should be constant
USTC.decimals (#137) should be constant
Add the constant attributes to state variables that never change.

withdrawToken(address,address,uint256) should be declared external:
- USTC.withdrawToken(address,address,uint256) (#219-225)
withdraw(address,uint256) should be declared external:
- USTC.withdraw(address,uint256) (#215-217)
Use the external attribute for functions never called from the contract.
