OurGlass - Smart Contract Audit Report
Summary
OurGlass is a new competitor in the meme-coin space that has gained a large community following in a short timeframe.
Notes on the Token Contract:Notes on the Staking Contract:
- 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 burn address, if desired.
- As of the date of this report, ~6.2% of the token's supply has been sent to the burn address.
- Pancakeswap holds ~11% of the token's supply as liquidity.
- 92% of liquidity has been locked in an unverified contract.
- The next largest holder has ~5.9%.
- Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
- A portion of the fee charged on transactions is stored in the contract and, once a threshold value is met, used to fund PancakeSwap liqudity.
- 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 owner of the contract will receive the LP tokens added from this process.
- There is a transfer limit of 5 trillion tokens per transaction.
- The owner of the contract can exclude and include users from transfer fees, update the maximum transaction amount, and update the fee percentages to any value.
- Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
- The contract utilizes SafeMath libraries to prevent overflows along with following the BEP20 standard.
- Users can deposit their GLASS tokens in this contract in order to earn further rewards in GLASS.
- Users can refer other users to deposit. To do so, they must have deposited at least 1 million tokens.
- The largest depositer and one pseudo-randomly chosen user will receive a reward each day .
- The randomness function, to an extent, relies on predictable environment variables. This is common, albiet not best practice; but the probability of miners maliciously changing these variables is extremley low.
- The team has worked with us to improve this contract for gas optimization and resolve issues around unbounded loops.
- SafeMath is utilized to prevent overflow issues.
Audit Findings Summary:
- No security issues were identified in our analysis.
- Ensure trust in the team as they have substantial control in the ecosystem and hold a modest number of tokens. We strongly recommend renouncing ownership.
- Be aware of the relatively low amount of liquidity available.
- Date: May 19th, 2021
- Update Date: May 25th, 2021 - Minor changes to the staking contract. Substantial issues exist.
- Update Date: June 14th, 2021 - Substantial logic rewrite to the staking contract to resolve numerous issues.
