Aurora Finance Token - Smart Contract Audit Report

Summary

Aurora Audit Report Aurora Finance is a new project that provides automated rewards to users who hold the token.

Aurora Finance's Token is deployed at 0xf6530899de1daae4388e1286eba6379d7ddf9c8f on the Binance Smart Chain Mainnet.

Notes on the Contract:
  • Aurora Finance is a fork of Reflect Finance. The key notable differences are the transfer tax which is 5x that of RFI, and the altered total supply.
  • The total supply of the token is 1 billion.
  • No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to 0x...dead.
  • 50% of the total supply has been send to the 0xdead address.
  • 5.2% of the tokens supply is locked with DxSale until October 2021.
  • 2.3% of the token's supply is in Pancakeswap liquidity.
  • 98% of liquidity has been locked locked with DxSale until October 2021.
  • The next largest holder has ~1.7%.

  • 100% of the fee 5% charged on token transfers is redistributed to existing token holders instantly and automatically at the time of each transaction.
  • The owner can exclude any address from the fee mechanism.
  • Ownership has been renounced.
  • Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant. As this contract is already deployed, this is merely informational.
  • Utilization of SafeMath to prevent overflows.

Audit Findings Summary
  • No external threats were identified.
  • The team will be vested a large amount of tokens.
  • A few wallets hold a large number of tokens in proportion to the liquidity pool.
  • Date: May 3rd, 2021
