caver.kct.kip7는 JavaScript의 객체로서 KIP-7을 구현하는 스마트 컨트랙트를 Klaytn 블록체인 플랫폼에서 쉽게 다룰 수 있도록 도와줍니다.
caver.kct.kip7는 KIP-7 토큰 컨트랙트를 구현하기 위해 를 상속합니다. caver.kct.kip7은 caver.contract와 동일한 속성값들을 가지며, 추가 기능 구현을 위해 메소드를 더 가지고 있습니다. 이 장은 caver.kct.kip7 메소드들 중 오직 새롭게 추가된 것들만 소개합니다.
caver.kct.kip7에서 사용된 abi와 바이트 코드는 예시를 사용하여 구현되었습니다.
The code that implements KIP-7 for caver-js is available on the .
For more information about KIP-7, see .
KIP-7 토큰 컨트랙트를 Klaytn 블록체인에 배포합니다. caver.kct.kip7.deploy를 사용해 배포한 컨트랙트는 KIP-7 표준을 따르는 대체 가능 토큰입니다.

Example
토큰 소유자의 토큰을 spender가 amount만큼 사용하도록 허락합니다.
이 메서드는 토큰 소유자가 트랜잭션 발신자로서 Klaytn 네트워크에 트랜잭션을 전송하며, 트랜잭션 수수료가 트랜잭션 발신자에게 부과됩니다.
Parameters
참고 amount 파라미터는 Number 타입 값을 받지만, 입력된 값이 Number.MAX_SAFE_INTEGER 범위를 초과하면 예상치 못한 결과 또는 오류를 발생시킬 수 있습니다. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
The sendParam object contains the following:
Return Value
Example
주어진 amount만큼의 토큰을 토큰 소유자 잔액에서 recipient에게 보냅니다. 토큰 소유자는 이 토큰 전송을 직접 실행해야 합니다. 따라서 토큰 소유자는 이 트랜잭션 발신자이어야 하며, 토큰 소유자의 주소는 반드시 sendParam.from 또는 kip7.options.from에 주어져야 합니다. sendParam.from 또는 kip7.options.from가 주어지지 않는다면 에러가 발생합니다.
Note that sending this transaction will charge the transaction fee to the transaction sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
Return Value
Example
주어진 amount만큼의 토큰을 토큰 소유자 잔액에서 recipient에게 안전하게 보냅니다. The token owner should execute this token transfer with its own hands. Thus, the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip7.options.from. Without sendParam.from nor kip7.options.from being provided, an error would occur.
Note that sending this transaction will charge the transaction fee to the transaction sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
Return Value
Example
Transfers the given amount of the token from the token owner's balance to the recipient. 토큰 소유자의 토큰을 보내도록 허락받은 주소가 이 토큰 전송 트랜잭션을 실행할 수 있습니다. 따라서 토큰을 보내도록 허락받은 계정이 이 트랜잭션 발신자이어야 하며, 허락받은 계정의 주소는 반드시 sendParam.from 또는 kip7.options.from에 주어져야 합니다. Without sendParam.from nor kip7.options.from being provided, an error would occur.
Note that sending this transaction will charge the transaction fee to the transaction sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
Return Value
Example
Safely transfers the given amount of the token from the token owner's balance to the recipient. The address who was approved to send the token owner's tokens is expected to execute this token transferring transaction. Thus, the approved one should be the sender of this transaction whose address must be given at sendParam.from or kip7.options.from. Without sendParam.from nor kip7.options.from being provided, an error would occur.
Note that sending this transaction will charge the transaction fee to the transaction sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
Return Value
Example
amount만큼의 토큰을 만들어 account에게 발행합니다. 이 함수는 토큰 총 공급량을 증가시킵니다.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
참고 만약 sendParam.from 또는 kip7.options.from이 주어졌다면, 이 주소는 반드시 MinterRole를 가진 발행자이어야 합니다.
Return Value
Example
Adds an account as a minter, who are permitted to mint tokens.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.

Return Value
Example
amount만큼의 토큰을 트랜잭션 발신자 잔액에서 제거합니다. Without sendParam.from nor kip7.options.from being provided, an error would occur.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
