MonkeyWorld Token - Smart Contract Audit Report

Summary

MONKS Audit Report MONKS ($MONKS) is a new community-driven DeFi token on the Binance Smart Chain that is an automatic liquidity providing protocol that pays out static rewards to holders.

Monkey World's Token contract is deployed at 0xa265255cfeb09f578185b7be251f8089dc888f92 on the Binance Smartchain mainnet.

Notes on the Contract:
The total supply of the token is initially set to one-hundred million $MONKS [100,000,000].
No minting or burn functions are present; and holders are not allowed to send tokens to the burn address. Tokens can be sent to the burn address upon deployment. If the owner does not exclude the burn address after deploying, it will participate in the reward distribution (as a regular holder) and increase proportionally to the rewards it receives. This is often used as a deflationary mechanism.
At the time of writing this report, 100% of the total $MONKS supply is in possession of the owner as this project is preparing for its presale.

There is a 'tax fee' and 'liquidity fee' on all transactions for any "non-excluded" address that participates in a transfer. The owner has the ability to modify these fees to any percentage at any time.
Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through the "tax fee" are removed from the circulating supply.
The liquidity fee charged on transactions is stored in the contract and, once a threshold value is met, used to fund Pancakeswap liquidity. This functionality can be enabled/disabled by the owner.
Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshhold as determined by the owner is met), then pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
The recipient of the newly created LP tokens is the Owner of the contract.
The owner of the contract can exclude and include accounts from transfer fees and reward distribution.
The owner has the ability to set and update a maximum transaction percent at any time, which will impose a limit to the number of tokens that can be transferred during any given transaction.
This maximum transaction amount does not apply to the owner during transactions where the owner is either the sender or the recipient.
The owner has the ability to use the "lock" function in order to temporarily set ownership to address(0). Ownership is restored after the duration of time determined by the owner has passed and they use the 'unlock' function. Ownership can additionally be restored (even if ownership was previously renounced), by using the unlock function a second time.
Ownership has not been renounced.
The contract utilizes SafeMath libraries along with following the ERC20 standard.
Audit Findings Summary
No external threats were identified.
Two members of the project team have passed KYC'd on June 21st.
We strongly recommend that the team renounces ownership after a successful launch.
Please ensure trust in the team prior to investing as they have substantial control within the ecosystem including control over the structure of the fees applied on transfers, as well as ownership of the LP Tokens.
