레거시 트랜잭션

caver.transaction.legacyTransaction.create(transactionObject)

LegacyTransaction은 레거시 트랜잭션을 의미합니다. Klaytn 계정은 AccountKeyLegacy을 사용해야만 LegacyTransaction을 실행할 수 있습니다. transactionObject는 LegacyTransaction을 생성하기 위해 아래와 같은 속성들을 가질 수 있습니다.

LegacyTransaction는 멤버변수로서 아래와 같은 속성들을 가지고 있습니다. 선택 사항인 속성들은 사용자가 LegacyTransaction를 생성할 때 transactionObject에 선택적으로 주어질 수 있는 속성들을 뜻합니다.

NOTE: You can create an instance of LegacyTransaction from RLP-encoded strings. Please refer to the below example. NOTE: caver.transaction.legacyTransaction.create is supported since caver-js v1.6.1.

NOTE: As of caver-js v1.8.1-rc.4, creating transactions is only supported using the create function. If you've been creating transactions using a constructor like new caver.transaction.legacyTransaction({...}), please change it to caver.transaction.legacyTransaction.create({...}).

Cancel

caver.transaction.cancel.create(transactionObject)

LegacyTransaction은 취소 트랜잭션을 의미합니다. transactionObject는 Cancel 트랜잭션을 생성하기 위해 아래와 같은 속성들을 가질 수 있습니다.

Cancel은 트랜잭션 풀에서 같은 논스를 가진 트랜잭션 실행을 취소합니다.

Cancel는 멤버변수로서 아래와 같은 속성들을 가지고 있습니다. 선택 사항인 속성들은 사용자가 Cancel 트랜잭션을 생성할 때 transactionObject에 선택적으로 주어질 수 있는 속성들을 뜻합니다.

NOTE: You can create an instance of Cancel from RLP-encoded strings. Please refer to the below example. NOTE: caver.transaction.cancel.create is supported since caver-js v1.6.1.

NOTE: As of caver-js v1.8.1-rc.4, creating transactions is only supported using the create function. If you've been creating transactions using a constructor like new caver.transaction.xcancelxx({...}), please change it to caver.transaction.cancel.create({...}).
