Guys, what is the difference between using and not using Indexed keyword in events? I am wanting to reduce gas costs

indexed is needed when you want to be able to filter by that parameter

Oh , so if my goal is to reduce gas costs on events , then indexed can be omitted right

Like I already have getters for params emitted in event , and also offchain solutions can get that with loops, so it that indexed necessary?

and those events are purely for the purpose of user readability of txs on etherscan

then yes remove indexed

okay , one more thing, what problems it might cause in future

just an estimation of the nature of the problem

if you don't use events there won't be any issue

alright 👌
