Xi Token - Smart Contract Audit Report
SummaryXi Token ($XI) is a new ERC20 token on the Ethereum Blockchain.
The Xi Token Token contract is deployed at 0x295B42684F90c77DA7ea46336001010F2791Ec8c on the Ethereum mainnet.
Notes of the contract:
Audit Findings Summary
- The total supply is set to 1 billion [1,000,000,000] $XI.
- 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.
- At the time of writing this report, 20% of the total supply has been sent to the 0x..dead address.
- The top five holders own a cumulative 53.9% of the total supply.
- Please note that there are a significant number of wallets that hold at least ~2x as many tokens than the tokens in the liquidity pool. The negative price impact would be substantial if these users were to sell their tokens.
- The contract complies with the ERC20 standard.
- The contract utilizes SafeMath libraries to prevent overflows/underflows.
- Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
- No external threats were identified.
