SAFESPACE - Smart Contract Audit Report
SAFESPACE is a new competitor in the meme-coin space that has gained a large community following in a short timeframe.We audited SAFESPACE's token contract contract at 0xe1DB3d1eE5CfE5C6333BE96e6421f9Bd5b85c987 on the Binance Smart Chain mainnet.
Overview of the Contract:
Audit Findings Summary
- 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 0x..dead address, if desired.
- As of the date of this report, ~32% of the token's supply has been sent to the 0xdead address.
- Pancakeswap holds ~7.6% of the token's supply as liquidity.
- 61% of liquidity has been locked with DxSale for 5 years. 37% of liquidity has been burned.
- The team holds 5% and then next largest holder has ~3.5%. The team has locked 1.8% of the supply in two equal parts for 6 and 12 weeks on our recommendation.
- 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, update the fee percentages and update how the fees are allocated.
- Ownership has been renounced, so none of these variables can be changed from their current state.
- 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.
- No security issues were identified in our analysis.
- Date: April 1st, 2021
- Update Date: April 28th, 2021 - Locking of tokens on our recommendation.
- Update Date: April 30th, 2021 - Renouncing of Ownership.
