caver.kct.kip17

caver.kct.kip17 helps you easily handle a smart contract that implements KIP-17 as a JavaScript object on the Klaytn blockchain.

caver.kct.kip17는 KIP-17 토큰 컨트랙트를 구현하기 위해 caver.contract를 상속합니다. caver.kct.kip17caver.contract와 동일한 속성값들을 가지며, 추가 기능 구현을 위해 메서드를 더 가지고 있습니다. 이 장은 caver.kct.kip17 메서드들 중 오직 새롭게 추가된 것만을 소개합니다.

The code that implements KIP-17 for caver-js is available on the Klaytn Contracts Github Repo. KIP-17 for caver-js supports Ownable interface. Using this, you can designate a contract owner when deploying a contract

For more information about KIP-17, see Klaytn Improvement Proposals.

caver.kct.kip17.deploy

caver.kct.kip17.deploy(tokenInfo, deployer)

KIP-17 토큰 컨트랙트를 Klaytn 블록체인에 배포합니다. caver.kct.kip17.deploy를 사용해 배포한 컨트랙트는 KIP-17 표준을 따르는 대체 불가 토큰입니다.

성공적으로 배포된 후, 프로미스는 새로운 KIP17 인스턴스를 반환할 것입니다.

Parameters

NameTypeDescription

tokenInfo

object

Klaytn 블록체인에 KIP-17 토큰 컨트랙트를 배포하는 데 필요한 정보입니다. 자세한 내용은 아래 표를 참조하세요.

deployer

string | object

keyring 인스턴스에 있는 계정 주소입니다. 이 주소가 KIP-17 토큰 컨트랙트를 배포합니다. 이 주소는 반드시 배포를 위해 충분한 KLAY를 가지고 있어야 합니다. 자세한 내용은 Keyring을 참조하세요. 트랜잭션 전송 시 사용할 필드를 자체적으로 정의하고 싶다면 객체 타입을 매개변수로 전달하면 됩니다. KIP-17 컨트랙트 배포 시 수수료 위임을 이용하고 싶다면, 객체 내 수수료 위임과 관련된 필드를 정의할 수 있습니다. 이 필드의 사용에 관한 내용은 approve의 매개변수 설명을 참고하십시오.

tokenInfo 객체는 다음을 반드시 포함해야 합니다:

NameTypeDescription

name

string

토큰 이름입니다.

기호

string

토큰 심볼입니다.

Return Value

PromiEvent: 이벤트 이미터와 결합된 프로미스이며 새로운 KIP17 인스턴스를 반환합니다. 추가로 다음 이벤트가 발생할 수 있습니다.

NameTypeDescription

transactionHash

string

트랜잭션이 전송된 직후 및 트랜잭션 해시를 사용할 수 있을 때 발생합니다.

receipt

object

트랜잭션 영수증을 사용할 수 있을 때 발생합니다. 영수증 객체 속성값들에 관한 자세한 정보는 getTransactionReceipt를 참고하십시오. KIP17 인스턴스의 영수증은 'logs' 속성 대신에 ABI로 파싱된 'events' 속성을 가지고 있습니다.

error

Error

전송 중 오류가 나타나면 발생됩니다.

Token Enrollment

  1. To enroll a token on a block explorer, the contract creator must fill out a submission request form. Make note of the specified information required on the form.

kip17.transferFrom

kip17.transferFrom(from, to, tokenId [, sendParam])

Transfers the token of the given token id, tokenId from the token owner's balance to another address. The address that was authorized to send the token owner's token (the operator) or the token owner him/herself is expected to execute this token transfer transaction. Thus, an authorized account or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip17Instance.options.from. Unless both sendParam.from and kip17Instance.options.from are provided, an error would occur. 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

NameTypeDescription

from

string

주어진 토큰 소유자 주소 또는 주어진 토큰을 전송하도록 승인받은 operator 주소입니다.

to

string

토큰을 받을 계정 주소입니다.

tokenId

BigNumber | string | number

전송하고 싶은 토큰의 토큰 ID입니다.

sendParam

object

(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of approve.

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.

kip17.safeTransferFrom

kip17.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 that was authorized to send the token owner's token (the operator) or the token owner him/herself is expected to execute this token transfer transaction. Thus, an authorized address or the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip17Instance.options.from. Unless both sendParam.from and kip17Instance.options.from are 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

NameTypeDescription

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

The id of the token you want to transfer.

data

Buffer | string | number

(선택 사항) 호출 시 함께 보낼 데이터입니다.

sendParam

object

(optional) An object with defined parameters for sending a transaction. For more information about sendParam, refer to the parameter description of approve.

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.

Creates a token with the given uri and assigns them to the given account. This method increases the total supply of this token.

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

Parameters

NameTypeDescription

to

string

tokenId

BigNumber | string | number

발행될 토큰 ID입니다.

kip17.burn

kip17.burn(tokenId [, sendParam])

Destroys the token of the given token id. Without sendParam.from nor kip17.options.from being provided, an error would occur.

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