Olympus Inu - Smart Contract Audit Report
Summary
Olympus Inu ($OHMINU) is a new community-driven DeFi token on the Ethereum Blockchain that pays out static token rewards to holders and sends ETH to the team.
Notes on the Contract:Audit Findings Summary
- The total supply is set to 1 trillion $OHMINU [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, 49.51% of the token's supply has been sent to the 0x...dead address.
- 7.49% of the total supply is in Uniswap liquidity.
- Of that liquidity, 99.67% of the LP tokens are locked in a token locking contract and will vest to the team on April 28th, 2022.
- The next five holders own a cumulative 10.57% of the total supply.
- There is a 2% tax fee and a 10% team fee on all transactions for any "non-excluded" address that participates in a transfer.
- Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through taxes are removed from the circulating supply.
- The team fee charged on transactions is swapped for ETH and sent to the contract address. The received ETH is then transferred to wallets controlled by the team.
- The contract features a cooldown mechanism when buying from Uniswap that enforces a maximum buy amount of 70,500,000,000 tokens and prevents a user from making another trade until after the cool down time of 30 seconds has elapsed since the user's previous trade.
- The contract features a blacklist which prevents accounts specified by the owner from being able to participate in transfers.
- As the project is deployed with Solidity v0.8.x, it is protected from overflows.
- Ownership has been renounced.
- No external threats were identified.
- Please be aware of the amount of liquidity available in proportion to the largest wallets.
- Date: November 5th, 2021
- Updated: November 10th, 2021 after the team renounced ownership.
