Meta Farm - Audit Report
Meta Farm ($MEF) is a new BEP20 token on the Binance Smart Chain.
We reviewed the MetaFarm contract that is deployed at 0x0Dc50b087EBCa4A5A4a2B68A2C736A6C8B3A3600 on the Binance Smart Chain Mainnet.
Notes on the Contract:
- The total supply of the token is set to 1 billion $MEF [1,000,000,000].
- No mint functions are accessible beyond deployment.
- Any user can burn their own tokens to reduce the total supply.
- At the time of writing this report, 100% of the total supply belongs to the owner.
- There is a tax fee on all transactions for any "non-excluded" address that participates in a transfer.
- The tokens collected through the tax fee are sent to the team's dev address.
- The owner can modify the tax fee to any percentage at any time.
- The owner can modify the dev address to any address at any time.
- The contract complies with the BEP20 standard.
- As the contract is deployed with Solidity v0.8.10 it is protected from overflows.
- Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
Audit Findings Summary
- No external threats were identified.
- Please ensure trust in the team prior to investing as they have substantial control in the ecosystem and own 100% of the total supply.
