1 Dollar - Smart Contract Audit Report

Summary

1 Dollar Token Audit Report 1 Dollar ($ONEUSD) intends to build a platform enabling flash loans to equalize DeFi markets.

For this audit we reviewed the project's token contract, deployed at 0xbf30a1dab8a2fa14b852a87914c377048cef18eb on the Binance Smart Chain Mainnet.

Notes of the Contract:

The initial total supply is 100 million [100,000,000] ($ONEUSD) tokens.
The team has the ability to mint tokens at any time.
There is one wallet that contains 79.5% of the tokens supply.
The second largest wallet contains ~14.5% of the tokens supply.
The remaining four wallets contain the other ~1% of the tokens supply.
No other ownership-related functions exist.
Some functions could be declared external instead of public to save a minimal amount of gas.
The token contract complies with the BEP20 standard.
Utilization of SafeMath to prevent overflows.
Audit Findings Summary:
No issues from external attackers were identified.
As with any ICO, ensure trust in the team prior to investing.
Further, ensure trust in the team as they have the ability to mint tokens.
