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.
We use metamask to sign the transaction. To sign your transaction without metamask u would need private key and public key of the account with which you want to make transaction. after that you can follow this etherum stack exchange link which shows how to make transaction with private key
