Spaceman - Smart Contract Audit Report
Summary
Spaceman is a new token with frictionless fee redistribution and liquidity adds.
Overview of the Contract:Audit Findings Summary
- The total supply of the token is set to 100,000,000,000,000,000.
- No mint or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- As of the date of this report, 57% of the token's supply has been sent to the 0xdead address.
- The token was listed directly on PancakeSwap with 10 BNB being paired against the 40% of the total supply.
- 7.5% of the supply is locked in an unverified contract and will be released to the team in ~6 weeks.
- Pancakeswap holds 3.5% of the token's supply as liquidity.
- 90% of liquidity is locked in an unverified contract and will unlock to the team in 4 months. 9% of liquidity is unlocked and held by the team.
- Three wallets hold more than the liquidity pool, between ~3.7% and ~5.4%
- The next largest token holder has ~1.6%.
- 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 ETH with the token, and adding it as liquidity to the BNB pair.
- 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 transaciton amount.
- The contract utilizes Solidity 0.8.3 which has built-in checks to prevent overflow issues along with following the BEP20 standard.
- No security issues were identified in our analysis.
- Ensure trust in the team as they have significant control in the ecosystem. We recommend renouncing ownership.
- Some wallets hold a large number of tokens in relation to the liquidity pool. If they were to sell all at once, there could be a large negative price impact.
