DLINK Token - Smart Contract Audit Report

Summary

DLINK intends to build a platform enabling flash loans to equalize DeFi markets.

For this audit we reviewed the project's token contract, deployed at 0x7f5a49c8b2cc62bf11b1e9f73a1dbf2e7220a97b on the Binance Smart Chain. .

Notes of the Contract:

The initial total supply is 1 billion tokens.
There is no way for tokens to be minted after deployment.
No ownership-restricted functions are present.
There is a 1% burn on all transactions of the token.
The team has sent ~58% of the token's supply to a presale platform.
The team still holds ~41% of the token's supply. We advise locking or burning a large majority of these tokens.

Some functions could be declared external instead of public, and basePercent can be set constant to save a minimal amount of gas. As this is already deployed, this is merely informational
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 presale, ensure trust in the team prior to investing.
Further, ensure trust in the team as they hold ~41% of the total supply.
Date: April 9th, 2021.
