DAOLand - Smart Contract Audit Report
Summary
DAOLand is a new BEP20 token.
We reviewed the DAOLand token contract at commit edb23af6c6bb3f7bf9bc499369720b8d1e845291 on the team's Github repository.
Notes of the contract:Audit Findings Summary
- The total supply of the token is 100 million [100,000,000].
- No minting or burn functions are present beyond deployment; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- There was no token allocation for our team to analyze as the contract has yet to be deployed to the mainnet.
- The contract utilizes an Admin role. The Admin address can withdraw any tokens erroneously sent to the contract.
- The contract includes functionality to interact with an external anti-sniper contract. The security of the anti-sniper contract cannot be verified by our team as this contract was out of scope for the purpose of this audit.
- The contract complies with the BEP20 standard.
- As the project is implemented with Solidity v0.8.x, it is protected from overflows.
- No external threats were identified.
- As with any presale, ensure trust in the team prior to investing.
