title: How to Create a DAPP without metamask
body: <p>I want to make a voting system with ethereum.
  I referred to this. : <a href="https://romeoh.tistory.com/entry/Solidity-Front-end-%EA%B5%AC%EB%8F%99%ED%95%98%EA%B8%B0?category=340661" rel="nofollow noreferrer">https://romeoh.tistory.com/entry/Solidity-Front-end-%EA%B5%AC%EB%8F%99%ED%95%98%EA%B8%B0?category=340661</a>
  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?</p>
  <p>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.</p>
