[EIP 712 signtypeddata](https://eips.ethereum.org/EIPS/eip-712)

위의 링크가 EIP 712에 대한 링크입니다.

signtypeddata가 기존의 정해진 틀을 가지고 데이터를 서명하는 것인데, 사용자가 자신이 어떤 데이터를 서명하는지  
직접 볼수있다는 것이 특징입니다.(bytecode가 아닌 string(json))

이것을 지원하나요??  
한다면 klaytn의 sdk(caver-js, caver-java)에서 해당 기능을 하는 함수는 어떤것인가요?

안녕하세요 질문 감사합니다.

현재 Klaytn SDK에서 SignTypedData 기능은 아직 지원되지 않습니다.  
감사합니다.

I would like to see support for EIP 712 as well. It’s important for signers to have clear visibility into what they are signing.

+1 For this feature. It means I can’t integrate Kaikas into [Snapshot](https://snapshot.org/#/), and I would imagine there are quite a few other applications that KLAY is disqualified for because of the absence
