Eros - Smart Contract Audit Report
Summary
Eros ($EROS) is a new BEP20 token on the Binance Smart Chain with a buyback system for burning supply.
Overview of the Contract:Audit Findings Summary
- The total supply of the token is set to 1 million [1,000,000] $EROS.
- No burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- The owner has the ability to assign and remove addresses to a Minter role.
- The assigned Minter(s) can mint tokens to any destination address at any time.
- At the time of writing this report, 100% of the total supply is in possession of the owner as the project was recently deployed.
- There is a 3% burn fee, a 3% buyback fee, and a 3% marketing fee on all transactions for any non-excluded address that participates in a transfer.
- The tokens collected through the burn fee and the buyback fee are used to fund the buyback functionality, which once a threshold value is met, is swapped for BNB and is stored in the contract address. Once a BNB buyback threshold is met, the BNB is used to buy tokens which are subsequently burned.
- The tokens collected through the marketing fee are stored in the contract and, once a threshold value is met, swapped for BNB and is sent to the team's marketing wallet. The Operator can update the marketing wallet to any address at any time.
- The owner has the ability to assign and remove addresses to an Operator role.
- The Operator of the contract can exclude and include accounts from all transfer fees.
- The threshold value for the burn, buyback, and marketing fees can be set by the Operator to any amount at any time.
- The contract features an Anti-Whale mechanism in which the Operator can impose a transaction limit for specified addresses. The transaction limit can be set to any value between 0.5% and 5% of the circulating supply.
- The Operator can enable/disable the AntiWhale functionality.
- The Operator can change the LP token address to any address at any time.
- The $EROS token smart contract utilizes logic from an external Referral contract that was not reviewed by our team as part of this audit.
- Ownership has not been renounced.
- The contract utilizes SafeMath libraries along with following the BEP20 standard.
- No issues from external attackers were identified.
- Please ensure trust in the team as they have subsantial control over the total token supply.
- We strongly recommend renouncing ownership after a successful deployment.
