ALORA Token

Alora.accumulatedOperatorTokensAmount (#608) is never initialized. It is used in:
- Alora.swapAndLiquify() (#737-752)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Alora.addLiquidity(uint256,uint256) (#764-775) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner,block.timestamp) (#766-773)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

Combination 1: Reentrancy vulnerabilities + 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.

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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

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-0.8.13 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.
