Before using any platform on Binance Smart Chain - Cub Finance included - you should do your own research and understand the risks of getting involved. What you're looking at on Cub Finance or any DeFi platform is a nascent industry. Blow-ups happen and risks are all over the place.
The contracts and code bases being used for Cub Finance have been thoroughly audited on other platforms, but that does not mean there is a 0% chance of systemic risk. If these risks are unacceptable, then it might be unwise to participate in platforms like Cub Finance and other DeFi platforms whether you're on Ethereum or Binance Smart Chain.
The auditing companies we have hired are publishing in-depth reports and deploying various security "watchtowers" to keep an eye on the platform and watch for any malicious activity. With this in mind, security is always going to be the default for this platform but underlying risk will always be present. DYOR!
Until our audit is publicly published, you can view the EGG and CUB contracts side by side to see what we changed. With platforms like these, making less changes is better. You can see here that we only changed naming variables and did not change any business logic. This is important because Goose Finance (and the contracts they've forked) have already been thoroughly audited.
You can also compare our on-chain contracts to their on-chain contracts:
