Blue varyon smart contract


My solidity level isn’t sufficient to determine if theres anything wrong with this, could anyone have a look and see what they think?

I really like this project and want to support them, its a very intersting idea and the team really seems dedicated, they have the support of governments and NGOs. This could be a live changing project for the world and I really want to invest. Check out the project here https://www.blue-frontiers.com/en/ and check out the documents section. Their plan is well thought out, sustainable, efficient and environmentally conscious. Just imagine a floating crypto city.
