NEPTUNES Token - Smart Contract Audit Report


NEP Token Audit Report NEPTUNES ($NEP) is a new DeFi token on the Binance Smart Chain.

For this audit we reviewed the project's token contract, deployed at 0xa74972093a7a1cc979d7dbede2ef921cbb53c91a on the BSC Mainnet.

Notes of the Contract:
  • The total supply of the token is initially set to 20,000 $NEP.
  • 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, 50% of the total supply belongs to the deployer address.
  • 25% of the total supply is stored in the $NEP contract address.
  • The remaining 25% belongs to an address that was granted tokens by the deployer.
  • The contract inclues the approveAndCall() function which enables additional use cases like cross-chain swaps.
  • No ownership-protected functions are present.
  • The contract utilizes SafeMath to prevent overflow and complies with the BEP20 standard.

Audit Findings Summary
  • No issues from external attackers were identified.
  • Date: July 24th, 2021.
