I want to make a voting system with ethereum. I referred to this. : https://romeoh.tistory.com/entry/Solidity-Front-end-%EA%B5%AC%EB%8F%99%ED%95%98%EA%B8%B0?category=340661 It was possible to vote by implementing the Web. But I had to press the approval button directly using metamask. Is it possible to proceed voting and pay gas without metamask extension program in Chrome?
If so, please let me know what method or algorithm you need. Also, if you have a link to refer to, I'd appreciate it if you could attach a link.
