크 완전 감사합니다.

```auto
RoleBasedKeyring {
  _address: '0xfd19936562747321d37e0df555aa03fd075c3145',
  _keys: [[ [PrivateKey] ], [[PrivateKey] ], [[PrivateKey] ] ] }

```

이렇게 잘 나옵니다.

늦은 시간에도 감사해요!

테스트 환경  
Network : Baobab.  
SDK : Caver-js v 1.5.0 ( Fee delegation tx 사용시 )  
Caver-js v 1.4.1 ( Account update 사용시 )  
Ken version : 1.3.0

테스트 시나리오

1. ken attach
2. personal.newAccount 로 Acc 생성
3. Caver-js v 1.4.1 로 Account update 실행
4. caver.klay.accounts.encrypt 실행이후 나오는 Result 를 for 문으로 추출
5. Result 를 json 파일로 변환
6. Caver-js v 1.5.0 Fee delegation tx 테스트 ( TxtypeFeeDelegatedValuetransfer 테스트 )
7. 사이닝 완료 및 TxHash 를 Baobab 네트워크에서 확인

잘 됩니당.

참고차 남겨드립니다. 🙂
