RugRelief Token - Smart Contract Audit Report
RugRelief ($RR) is a new community-driven DeFi token on the Ethereum Block Chain that pays out static rewards to holders.
Notes on the Contract:
Audit Findings Summary
- The total supply of the token is initially set to 1 trillion $RR [1,000,000,000,000].
- 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, 31.5% of the total $RR token supply is in Uniswap liquidity.
- Out of that liquidity, 100% of the LP tokens are locked in a token locking contract that will vest to the team on July 23, 2022.
- The top 5 holders account for 15% of the total $RR token supply.
- There is a 'tax fee', 'liquidity fee', and 'marketing 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.
- A portion of the tax fee is redistributed to existing token holders instantly and automatically at the time of each transaction.
- The liquidity fee charged on transactions is stored in the contract and, once a threshold value is met, is used to buy WETH which is subsequently sent to the marketing address (which the team has the ability to change at any time). This functionality can be enabled/disabled by the owner.
- The marketing fee that is applied during transfers can vary depending on if the holder is selling to Uniswap as there will be a different fee structure in place that is set by the owner.
- 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.
- Ownership has not been renounced.
- The contract utilizes SafeMath libraries along with following the ERC20 standard.
- As the project is implemented with solidity version ^0.8.0, it is protected from overflows.
- No external threats were identified.
- We recommend that the team renounces ownership.
- Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
