solidity

Can anyone help me how does bridge work in code. I know how it works practically but I need resources for it to build it from scratch or with help of libraries

Do you mean to make a bridge between chains?

If so, you need to use a messaging system of some sort. Suggest taking a look at wormhole if you're interested:
