Mongoose - Smart Contract Audit Report
Mongoose ($MONGOOSE) is a new ERC20 token on the Ethereum Blockchain that is an automatic liquidity providing protocol that pays out static rewards to holders.
Notes on the Contract:
Audit Findings Summary
- The total supply of the token is set to 69 sextillion $MONGOOSE [69,000,000,000,000,000,000,000].
- No minting or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- At the time of writing this report, 9.27% of the total supply is in Uniswap liquidity.
- Of that liquidity, 70.18% of the LP tokens have been sent to the 0x00 address.
- 28.45% of the LP tokens are stored in a Unicrypt token locking contract and will vest to the team on June 1st, 2022.
- The next five holders own a cumulative 11.34% of the total supply.
- There is a 1% tax fee and a 12% liquidity fee on all transactions for any "non-excluded" address that participates in a transfer.
- The tokens collected from the tax fee are removed from the circulating supply; This serves as a frictionless fee redistribution which automatically benefits all token holders at the time of each transaction.
- The tokens collected from the liquidity fee during transfers are stored in the contract address balance. Once the threshold value of 690 quintillion tokens is met, a swap will occur for the purpose of funding Uniswap liquidity.
- Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshold number of tokens is met), then pairing the received ETH with the token, and adding it as liquidity to the ETH pair.
- The recipient of the newly created LP tokens is the 0x00 address.
- The remaining portion of ETH in the contract is sent to the team's Marketing wallet.
- Although a maximum transaction amount exists in the contract, it is currently set to 100% of the total supply and cannot be changed.
- Although the Safemath library is utilized, the contract is deployed with Solidity v0.8.9 which has built-in overflow checks. Safemath could be safely removed to reduce contract size and increase gas savings.
- Some gas optimizations can be achieved through declaring functions external instead of public, and some variables that could be declared constant. As this contract is already deployed, this is merely informational.
- Ownership has been renounced by the team.
- No external threats were identified.
- Please be aware of the amount of liquidity available in proportion to the largest wallets.
