Olympus Inu - Smart Contract Audit Report


SLINK Audit Report 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.

Olympus Inu's Token contract is deployed at 0x98F817765f69c802a7b188A3165a3267aD2d1123 on the Ethereum mainnet.

Notes on the Contract:
  • 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.

Audit Findings Summary
  • 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.
