This is an audit done in the final version of the smart contract in which will be the one used when the project goes live.

This smart contract has been reviewed by George Stamp and found no backdoor code, and the owner has good amount privileges to make modifications to the contract once published mostly disabling/enabling of added features but not the users yield functions. There is no malicious code that allows the owner (or other) to withdraw all funds from the smart contract.

This is a distant fork of several projects such as BNB MINER, BNB CROPS MINER and other features from famous projects the team also did some original features such as gambling, fixed yield income and over income restrictions.

Rewards from these features are all being converted to miner which will not affect the TVL but will increase the capacity of investors to earn overtime.
Features are not being executed per user transaction with this version, which fixed with the gas fee issue.

The 'magic formula' has also been modified same as what was done with Crops.

The smart contract has a built in anti-bot feature that will blacklist wallets who will interact more than 2 times with the contract when it is not yet started. Those funds from will be treated as donations.

The smart contracts utilize re-entrancy guard to prevent re-entrant calls.

The has a built in auto-compound feature, user select the no of days that they want it to continuously compounding along with the required average gas fee amount. Users will need to manually start their auto-compound again once it ends.

This smart contract is deemed SAFE for investing, with the disclaimer that this is a ROI miner application where the users investments cannot be withdrawn, and the user earns their funds back over time through withdrawing investment interest.
