🅿️ [Pushin 🅿️] Token

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

PushinP._getCycle(uint256,uint256) (#1011-1016) uses a weak PRNG: "cycle = (secondsElapsed - (secondsElapsed % CYCLE_SECONDS)) / CYCLE_SECONDS + 1 (#1013)"
Do not use block.timestamp, now or blockhash as a source of randomness

Contract name (Pushin 🅿️) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

PushinP.addLiquidity(uint256,uint256) (#1056-1069) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1061-1068)
Ensure that all the return values of the function calls are used.

PushinP.allowance(address,address).owner (#953) shadows:
- Ownable.owner() (#570-572) (function)
PushinP._approve(address,address,uint256).owner (#982) shadows:
- Ownable.owner() (#570-572) (function)
Rename the local variables that shadow another component.

PushinP.setLiquidityFeePercent(uint256) (#924-926) should emit an event for:
- _liquidityFee = liquidityFee (#925)
Emit an event for critical parameter changes.

PushinP.setLiquidityAddress(address)._add (#928) lacks a zero-check on :
- liquidityAddress = _add (#929)
Check that the address is not zero.

- _isExcludedFromFee[owner()] = true (#883)

Ownable.unlock() (#617-622) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > _lockTime,Contract is locked until 7 days) (#619)
PushinP._getCycle(uint256,uint256) (#1011-1016) uses timestamp for comparisons
Dangerous comparisons:
- cycle >= FINAL_CYCLE (#1014)
PushinP._getSupply(uint256,uint256) (#1022-1034) uses timestamp for comparisons
Dangerous comparisons:
- currentCycle > era.endCycle (#1026)
Avoid relying on block.timestamp.

Pragma version^0.8.9 (#20) 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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#523-544):
