caver.klay.KIP17

KIP-17 표준을 구현한 스마트 컨트랙트와 상호작용하는 데 사용되는 caver-js 객체입니다.

caver.klay.KIP17은 KIP-17 표준을 구현한 스마트 컨트랙트를 JavaScript 객체 형태로 Klaytn 블록체인에서 손쉽게 다룰 수 있도록 돕습니다.

caver.klay.KIP17는 KIP-17 토큰 컨트랙트를 구현하기 위해 caver.klay.Contract를 상속합니다. caver.klay.KIP17은 caver.klay.Contract와 동일한 속성값들을 가지며, 추가 기능 구현을 위해 메서드를 더 가지고 있습니다. 이 장은 caver.klay.KIP17 메서드들 중 오직 새롭게 추가된 것만을 소개합니다.

caver-js에서 KIP-17을 구현한 예시는 Klaytn Contracts Github Repo에서 확인할 수 있습니다.

KIP-17에 관한 더 자세한 정보는 Klaytn Improvement Proposals를 참조하십시오.

참고 caver.klay.KIP17은 caver-js v1.4.1부터 지원됩니다.

caver.klay.KIP17.deploy

caver.klay.KIP17.deploy(tokenInfo, deployer)

KIP-17 토큰 컨트랙트를 Klaytn 블록체인에 배포합니다. caver.klay.KIP17.deploy를 사용해 배포한 컨트랙트는 KIP-17 표준을 따르는 대체 불가 토큰입니다.

성공적으로 배포된 후, 프로미스는 새로운 KIP17 인스턴스를 반환할 것입니다.

kip17Instance.transferFrom

kip17Instance.transferFrom(from, to, tokenId [, sendParam])

주어진 토큰 ID tokenId를 가진 토큰을 토큰 소유자 잔액에서 다른 계정으로 전송합니다. The address who was approved to send the token owner's token (the operator) or the token owner itself is expected to execute this token transferring transaction. 따라서 토큰을 보내도록 허락받은 계정 또는 토큰 소유자가 이 트랜잭션 발신자이어야 하며, 허락받은 계정의 주소는 반드시 sendParam.from 또는 kip7Instance.options.from에 주어져야 합니다. sendParam.from 또는 kip7Instance.options.from가 주어지지 않는다면 에러가 발생합니다. It is recommended to use safeTransferFrom whenever possible instead of this method.

Note that sending this transaction will charge the transaction fee to the transaction sender.

Parameters

Type
Description

from

String

The address of the owner or the approved operator of the given token.

kip17Instance.safeTransferFrom

kip17Instance.safeTransferFrom(from, to, tokenId [, data] [, sendParam])

Safely transfers the token of the given token id tokenId from the token owner's balance to another address. The address who was approved to send the token owner's token (the operator) or the token owner itself is expected to execute this token transferring transaction. Thus, the approved one or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip7Instance.options.from. Without sendParam.from nor kip7Instance.options.from being provided, an error would occur.

If the to is a contract address, it must implement IKIP17Receiver.onKIP17Received. otherwise, the transfer is reverted.

Note that sending this transaction will charge the transaction fee to the transaction sender.

Parameters

Name
Type
Description

from

String

The address of the owner or the approved operator of the given token.

to

String

The address of the account to receive the token.

tokenId

BigNumber \

String | Number

data

Buffer \

String | Number

sendParam

Object

NOTE The tokenId 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

Promise returns Object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP-17 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

Example

// Send via a sendParam object with the from field given (without data)

Note that the pause method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.

Parameters

Name
Type
Description

sendParam

Object

NOTE If sendParam.from or KIP17Instance.options.from were given, it should be a pauser with PauserRole.

Return Value

Promise returns Object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP-17 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

Example

// Send via a sendParam object with the from field given 
> kip17Instance.pause({ from: '0x{address in hex}' }).then(console.log)
