OlaLand Token - Smart Contract Audit Report

Summary

OlaLand Audit Report OlaLand Token ($OL) is a new BEP20 token on the Binance Smart Chain.

The OlaLand Token contract is deployed at 0xab00faa74269cbe8465eedbd468cd4da2e92d478 on the Binance Smart Chain Mainnet.

Notes of the contract:
  • The total supply of the token is set to 21 million [21,000,000] $OL.
  • No minting functions are present 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 $OL token supply is in possession of the owner.

  • Although the contract inherits the Ownable library, no ownership-restriction functions are present.
  • Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
  • The contract complies with the BEP20 standard.
  • As the project is deployed with Solidity v0.8.5, it is protected from overflows.
Audit Findings Summary
  • No external threats were identified.
  • Please ensure trust in the team prior to investing as they have control over the total token supply.
