GOIN - Audit Report

Summary

GOIN ($GOIN) is buildig a new BEP20 token.

We reviewed the GOIN contract at commit 4688666cafbef6aaf2114e4798ca3107a02d07b8 on the team's private Github repository.

Notes on the Contract:
No mint functions are accessible beyond deployment.
Any user can burn their own tokens to reduce the total supply.
There was no token allocation for our team to analyze as the contract has yet to be deployed to the mainnet.

The contract complies with the BEP20 standard.
No ownership-restricted functions are present.
As the contract is implemented with Solidity v0.8.2 it is protected from overflows.
Some gas optimizations can be achieved through declaring functions external instead of public and some variables constant.

Audit Findings Summary
No external threats were identified.
As with any presale, please ensure trust in the team prior to investing.
