Best practices for managing wallets in DeFi project

Hi everyone! Like many others here I am trying to create a DeFi project with own token and NFT. We already created some tokenomics model but stacked on step when we need managing incoming costs (BNB) from user.

I researched so many projects and I noticed that most have separate wallets/wallets for futher tokens flow. I am completely lost here. Can you give any advice/links, who faced similar design?

Thanks a lot!!!

You don’t need to manage wallets, you just need to connect to them. Or do you mean something else? Can you add more detail β€œI noticed that most have separate wallets/wallets for futher tokens flow” and give examples.
