transactions – How to create a simple lightweight wallet (without extraction) for an Altcoin


I am trying to create a wallet using electrum for an altcoin which uses the Scrypt algorithm. I'm looking for tutorials that can show a step-by-step process on how to create a simple wallet for this altcoin that simply sends, receives, and stores your coin for Windows, Linux, and Android. Anyone have any recommendations on how to do it or where I can try to build it myself?

I prefer to use electrum because there are several repositories of clones for electrum and it is quite simple to use, but I am open to other easier options.

Thanks again!
