Hi guys, im not developer. But how can i send transaction with edited code? Or my own code. What i need?

you can send bytecode with your transaction, thats also how contracts get deployed

Through metamask?

yeah, metamask can also do it

I need to represent my solidity code as bytecode, yes? And send to contract? Probably it better to do it from special soft like remix?

that would be the easiest, yes

Ok, thanks
