Summary

SafeElon Finance Audit Report SafeElon is a deflationary token with frictionless fee redistribution on Ethereum.

We audited SafeElon's token contract, deployed at 0x07be1ead7aebee544618bdc688fa3cff09857c32 on the Ethereum mainnet.

Overview of the Contract:
  • The initial total supply of the token is 400 million. Due to burns, the current total supply is about 388 million.
  • No minting functions are present.
  • 18.2% of the token's current supply has been sent to the Burn address.
  • 17% of the token's supply is locked and will vest to the team in 1 month.
  • Uniswap holds ~6.7% of the total supply as liquidity.
  • 98.5% of liquidity is locked for 6 months.
  • The charity wallet holds 5.1% of the supply.
  • The next largest holder has 4.7% of the supply.

  • Users who hold tokens will automatically receive a 1% of the 5% fee incurred on transactions.
  • 1% of the 5% transaction fee shall be burned.
  • The final 3% of the transaction fee will be sent to the charity.
  • The funds collected from charity fee will be held in a wallet controlled by the team.
  • In addition, the contract implements a maximum amount of tokens that can be sent in a transaction in the amount of 400 million. As this is the total supply, this has no impact on user functionality.

  • The owner has the ability to exclude and include users from the fee mechanism.
  • The owner can also update the address of the charity wallet at any time.
  • No other ownership-restricted functions are present.
  • The contract utilizes SafeMath libraries to prevent overflows.
Audit Findings Summary
  • No security issues were detected in the analysis.
  • Ensure trust in the team as they control the charity wallet and will be granted a large number of tokens in 1 month.
  • A few whales hold a somewhat large number of tokens.
