Hello,
I always been just investing over the years and never really ever used any type of dapps at all. I only ever used trust wallet dex feature. I was just wondering how should I go about learning how to use them correctly? Also, any safety concerns or anything that I should be aware off? I would like to try some type of defi or anything else that would be useful to try/learn/use etc.
Any help is appreciated as always thank you.

The internal code (smart contracts) of Dapps applications runs on a decentralized network, not on a centralized server. These applications use the Ethereum blockchain for data storage and smart contracts for their algorithms.
