How are smart contacts, bep/erc network tokens and staking pools created?

Question

blockchain

Hello, I would like to study the development of smart contracts, the sphere itself is interesting, but I have no experience. I would like to know what language smart contacts write in, create tokens in the bep2 / bep20 erc / erc20 network, etc., such as PancakeSwap, how do Defi dapp applications, again as an example of PancakeSwap, and how do they create PoS Staking pools where they place various tokens? what language is used for this? Is there any literature? Couldn't find anything concrete. Where to start studying?

Answer 1

There is a lot of literature on the Internet, mostly in English.
Learn how the Ethereum blockchain works, how smart contracts work.
Contracts are written in the Solidity language. After learning the basics, theory, understand how pancakeswap, uniswap work. And further along the study task list: defi, dapp, etc.
