PuppyDoge - Smart Contract Audit Report
PuppyDoge is a new token with automatic liquidity adds that pays users dividends in BNB.We audited PuppyDoge Finance's token contract at 0x19983df692be8fa81c60fd27d6fc91e8928fa97a on the Binance Smart Chain mainnet.
Overview of the Contract:
Audit Findings Summary
- The total supply of the token is set to one quadrillion.
- No mint 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, 81.53% of the total supply is stored in an unverified contract.
- The top 5 token holders control 5.17% of the total supply.
- The fixed sale is hardcoded to start on Aug 2, 2021 at 18:00 UTC and lasts for 10 minutes or until there has been 600 fixed sale buyers.
- During the fixed sale, only the bounce fixed sale wallet controlled by the team can perform transfers to fixed sale early participants.
- Trading is enabled for everyone starting on Aug 4, 2021 at 18:00 UTC.
- There is a maximum transaction amount of 1 trillion tokens during sell transactions to PancakeSwap; this does not apply to addresses excluded from fees and during liquidity-adds.
- There is a 20% tax fee charged on each transaction that is stored in the contract balance; fees are increased by a factor of 1.2x on sell tranasctions to PancakeSwap.
- Once a threshold value is met, 25% of the contract balance is used to fund PancakeSwap liquidity.
- Liquidity-adds are funded by selling half of the tokens collected as fees, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
- The newly created LP tokens are locked forever in the 0x..dead address.
- The remaining tokens in the contract balance are swapped for BNB and are automatically distributed as dividends to the token holders eligible for dividends.
- A user must hold 10 billion PUPPY tokens (0.001% of the total supply) to be eligible for dividends.
- Once dividends are distributed, they will need to be claimed; claiming happens automatically on each transfer.
- Dividend rewards can also be claimed manually by kicking off the claim cycle, which will process all eligible token holders.
- Alternatively, a user can manually claim dividends as an individual.
- There is a wait-time of 1800 seconds (0.5 hours) between claiming dividend rewards.
- Claimed dividends are sent to the user's wallet address.
- The owner is able to exclude any address from dividends or fees at any time.
- The owner is able to update the Dividend Tracker and UniswapV2Router contract addresses at any time.
- The owner is able to update the maximum amount of gas used for processing to a value between 200,000 and 500,000 at any time; the initial value is 300,000.
- The owner is able to update the amount of time a user must wait between claiming dividends to a value between 0.5 and 24 hours (in seconds).
- The owner is able to add any address as a fixed sale early participant at any time.
- Some functions could have been declared external and some state variables could have been declared constant for gas optimization.
- The contract utilizes the SafeMath library to prevent overflows along with following the ERC20 standard.
- No security threats from outside attackers were identified.
- As with any presale, ensure trust in the team prior to investing.
- Further, ensure trust in the team as they have some control in the ecosystem.
